The following judgments were delivered: KRISHNA IYER. The Root Thought The abolition of slavery has gone on for a long time. Rome abolished slavery	 America abolished it	 and we did	 but only the words were abolished not the thing. This agonising gap between hortative hopes and human dupes vis a vis that serf like sector of Indian society	 strangely described as Scheduled Castes and Scheduled Tribes (SCs and STs	 for short)	 and the administrative exercises to bridge this big hiatus by processes like reservations and other concessions in the field of public employment is the broad issue that demands constitutional examination in the Indian setting of competitive equality before the law and tearful inequality in life. A fasciculus of directions of the Railway Board has been attacked as ultra vires and the court has to pronounce on it	 not philosophically but pragmatically. "The philosophers have only interpreted the world in various ways; the point is to change it" this was the founding fathers ' fighting faith and serves as perspective setter for the judicial censor. 193 The Backdrop The social backdrop to the forensic problem raised in this litigation is best projected by lines of poetry quoted in Nehru 's Autobiography: Bowed by the weight of centuries he leans Upon his hoe and gazes on the ground	 The emptiness of ages on his face	 And on his back the burden of the world. The Problem The dynamics and dialectics of social justice vis a vis the special provisions of the Constitution calculated to accelerate the prospects of employment of the harijans and the girijans in the civil services with particular emphasis on promotions of these categories in the Indian Railways that	 in all these cases	 is the cynosure of judicial scrutiny	 from the angle of constitutionality in the context of the guarantee of caste free equality to every person. Petitioners ' Challenge The gravamen of the constitutional accusation levelled in this bunch of quasi class actions under article 32 of the Constitution and argued by a battery of counsel led by Shri Shanti Bhushan	 with heat and light	 passion and reason	 is the heartless discrimination shown against vast numbers of members employed by the Railway Administration through its policy directives	 by bestowal of unconscionably 'pampering ' concessions	 at promotion levels	 on these social brackets belonging to the historically suppressed SCs & STs	 heedless of over all administrative efficiency in the Indian Railways and frustrating the promotional hopes of the larger human segments of economically downtrodden senior members. The fall out of this 'benign discrimination ' of helping out the weakest sections has been to blow up	 out of all proportion to the social realities	 the 'backwardness ' syndrome so as embrace many politically powerful castes disguised as Backward Classes. This constitutional amulet	 rooted largely in caste	 the petitioners lament	 has been misused and applied in educational and employment fields on an escalating scale. The perverted result is that a caste riven nation is a spectre that haunts the land	 pushing back the patriotic prospect of a homogenised Indian Society of casteless equality and projecting instead the divisive alternative of a heterogeneous caste map of Bharat. The fundamental failure of this sterile scheme of reservation wise circumvention of the fundamental right to equality	 ideologically and pragmatically speaking	 has deepened the pathological condition of communalism besetting the Indian polity 194 and split the have nots into snarling camps a consummation disastrously contrary to the constitutional design of abolition of socioeconomic inequality through activist stratagem of equalisation geared to actual attainment of integrated equality. Logically	 the argument leads to the formulation that each caste and community is bargaining politically for bigger bites of the educational and employment cake so much so merit becomes irrelevant or takes a back seat and 'backward ' birth brings a boon. The constitutional stultification of an integrated India through misuse of 'reservation ' power provided for in articles 15 and 16 meant for the direct 'dalits ' the pollution	 by the political Executive	 of our founding creed of an egalitarian order by playing casteification politics and the morbid dilution of 'backwardness ' marring the dream of a secular republic by the nightmare of a feudal vivisection of the people if this picture drawn by some counsel be true	 even in part	 the basic task of transforming the economic order through social justice will be baulked through destructive communal disputes among the masses. Maybe	 this may weaken the social revolution	 leave an indelible stain and incurable wound on the body politic and justify the censure by history of the engineers of our political power and electoral processes. Hearing the arguments of the petitioners one wonders	 "Is caste the largest political party ?" Has protective discrimination	 so necessary in an insufferably unequal society	 created a Frankenstein 's monster ? Have we no dynamic measures to drown social	 economic and educational backwardness of whole masses except the traditional self perpetuating quasi apartheidisation called 'reservation ' ? Surely	 our democratic	 secular socialist republic is no wane moon but a creative power rooted in equal manhood	 an egalitarian reservoir of vast human potential	 a demographic distribution of talent benumbed by brahman centuries of social injustice but now seeking human expression under a new dispensation where 'chill penury ' shall no longer 'repress their noble rage '. Caste	 undoubtedly	 in a deep seated pathology to eradicate which the Constitution took care to forbid discrimination based on caste	 especially in the field of education and services under the State. The rulings of this court	 interpreting the relevant Articles	 have hammered home the point that it is not constitutional to base identification of backward classes on caste alone qua caste. If a large number of castes masquerade as backward classes and perpetuate that division in educational campuses and public offices	 the whole process of a caste free society will be reversed. We are not directly concerned with backward classes as such	 but with the provisions ameliorative of the 195 Scheduled Castes and the Scheduled Tribes. Nevertheless	 we have to consider seriously the social consequences of our interpretation of article 16 in the light of the submission of counsel that a vested interest in the caste system is being created and perpetuated by over indulgent concessions	 even at promotional levels	 to the Scheduled Castes and the Scheduled Tribes	 which are only a species of castes. "Each according to his ability" is being substituted by "each according to his caste"	 argue the writ petitioners and underscore the unrighteous march of the officials belonging to the SCs & STs over the humiliated heads of their senior and more meritorious brothers in service. The after math of the caste based operation of promotional preferences is stated to be deterioration in the over all efficiency and frustration in the ranks of members not fortunate enough to be born SCs & STs. Indeed	 the 'inefficiency ' bogie was so luridly presented that even the railway accidents and other operational calamities and managerial failures were attributed to the only villain of the piece viz.	 the policy of reservation in promotions. A constitutionally progressive policy of advantage in educational and official career based upon economic rather than social backwardness was commended before us by counsel as more in keeping with the anti caste	 pro egalitarian tryst with our constitutional destiny. And	 Shri Shanti Bhushan	 at one stage	 helped the court realise the consequences of its verdict if it upheld the pampering package of promotional preferences by warning us of running battles in the streets	 a sort of caste war	 against birth based 'privileges ' for the harijan girijan millions. Our Approach Of course	 judicial independence has one dimension	 not fully realised by some friends of freedom. Threats of mob hysteria shall not deflect the court from its true accountability to the Constitution	 its spirit and text belighted by all the sanctioned materials The other invisible sacrifice of judicial independence relevant to this case is the unwitting surrender to "the spirit of the group in which the accidents of birth or education or occupation or fellowship have given us (judges) a place. No effort or revolution of the mind will overthrow utterly and at all times the empire of these subconscious loyalties. " We quote what the great Justice Cardozo has courageously confessed : I have spoken of the forces of which judges avowedly avail to shape the form and content of their judgments. Even these forces are seldom fully in consciousness. They lie so near the surface	 however	 that their existence and 196 influence are not likely to be disclaimed. But the subject is not exhausted with the recognition of their power. Deep below consciousness are other forces	 the likes and the dislikes	 the predilections and the prejudices	 the complex of instincts and emotions and habits and convictions	 which make the man whether he be litigant or judge. The great tides and currents which engulf the rest of men do not turn aside in their course and pass the judges by. . . We shall never be able to flatter ourselves	 in any system of judicial interpretation	 that we have eliminated altogether the personal measures of the interpreter. In the moral sciences	 there is no method or procedure which entirely supplants that subjective reason. We may figure the task of the judge	 if we please	 as the task of a translator	 the reading of signs and symbols given from without. None the less	 we will not set men to such a task	 unless they have absorbed the spirit	 and have filled themselves with a love	 of the language they must read. The British echo of this judicial weakness is heard in Prof. Griffith 's words: These judges have by their education and training and the pursuit of their profession as barristers	 acquired a strikingly homogeneous collection of attitudes	 beliefs and principles	 which to them represents the public interest. The emphasis on the subtle invasions from within upon functional autonomy and forensic objectivity mentioned by Cardozo will be evident when we turn to the pathetic saga of the depressed classes	 even today	 painted by the other side. The learned Attorney General	 less militant but not less firm in his submissions	 called all this a caricature of the poignant facts of life and called upon us to assess the facts with cold objectivity and warm humanity casting aside possible sympathies suggested by Justice Cardozo and Prof. Griffith. We	 as judges dealing with a socially charged issue of constitutional law	 must never forget that the Indian Constitution is a National Charter pregnant with social revolution	 not a Legal Parchment barren of militant values to usher in a democratic	 secular	 socialist society which belongs equally to the masses including the harijan girijan millions hungering for a humane deal after feudal colonial history 's long night. Granville Austin quotes profusely from the Constituent Assembly proceedings to prove the goal of the Indian Constitution to be 197 social revolution. Radhakrishnan	 representing the broad consensus	 said that India must have a 'socioeconomic revolution ' designed not only to bring about the real satisfaction of the fundamental needs of the common man	 but to go much deeper and bring about 'a fundamental change in the structure of Indian society '. The Cultural Core of the Constitutional Protection: Let us get some glimpses of history to get a hang of the problem. 'In thy book record their groans ' may be the right quote to begin with. We cannot blink at the agony of the depressed classes over the centuries condemned by all social reformers as rank irreligion and social injustice. Swami Vivekananda	 for instance	 stung by glaring social injustice	 argued(2): The same power is in every man	 to the one manifesting more	 the other less. Where is the claim to privilege. All knowledge is in every soul	 even in the most ignorant	 he has not manifested it	 but	 perhaps he has not had the opportunity the environments were not	 perhaps	 suitable to him. When he gets the opportunity he will manifest it. The idea that one man is born superior to another has no meaning in Vedanta; that between two nations one is superior and the other inferior has no meaning whatsoever. . Men will be born differentiated; some will have more power than others. We cannot stop that. but that on account of this power to acquire wealth they should tyrannies and ride roughshod over those	 who cannot acquire so much wealth	 is not a part of the law	 and the fight has been against that. The enjoyment of advantage over another is privilege	 and throughout ages the aim of morality has been its destruction. . . Our aristocratic ancestors went on treading the common masses of our country under foot till they became helpless	 till under this torment the poor	 poor	 people nearly forgot that they were human beings. They have been compelled to be merely hewers of wood and drawers of water for centuries	 so much so	 that they are made to believe that they are born 198 as slaves	 born as hewers of wood and drawers of water. With all our boasted education of modern times	 if anybody says a kind word for them	 I often find our men shrink at once from the duty of lifting them up	 these poor downtrodden people. Not only so	 but I also find that all sorts of most demoniacal and brutal arguments	 culled from the crude ideas of hereditary transmission	 and other such gibberish from the western world are brought forward in order to brutalise and tyrannies over the poor	 all the more. Aye	 Brahmins	 if the Brahmin has more aptitude for learning on the ground of heredity than the Pariah	 spend no more money on the Brahmin 's education	 but spend all on the Pariah. Give to the weak	 for there all the gift is needed. Our poor people	 these down trodden masses of India	 therefore	 require to hear and to know what they really are. Aye	 let every man and woman and child	 without respect of caste or birth	 weakness and strength	 hear and learn that behind the strong and the weak	 behind the high and the low	 behind everyone	 there is that Infinite Soul	 assuring that infinite possibility and the infinite capacity of all to become great and good. Let us proclaim to every soul 'Arise	 awake and stop not till the goal is reached. Arise	 awake ! Awake from the hyprotism of weakness. None is really weak; the soul is infinite	 omnipotent and omniscient. Stand up	 assert yourself	 proclaim the God within you	 do not deny Him ! Too much of inactivity	 too much of weakness	 too much of hypnotism has been and is upon our race. . Power will come	 glory will come	 goodness will come	 purity will come	 and everything that is excellent will come	 when this sleeping soul is roused to self conscious activity. . Our proletariat are doing their duty. . is there no heroism in it ? Many turn out to be heroes	 when they have some great task to perform. Even a coward easily gives up his life	 and the most selfish man behaves disinterestedly when there is a multitude	 to cheer them on but blessed indeed is he who manifests the same unselfishness and devotion to duty in the smallest of acts. unnoticed by all and it is you who are actually doing this	 ye ever trampled labouring classes of India ! I bow to you. There was the Everest presence of Mahatma Gandhi	 the Father of the Nation	 who staked his life for the harijan cause. There was Baba 199 Saheb Ambedkar a mahar by birth and fighter to his last breath against the himalayan injustice to the harijan fellow millions stigmatised by their genetic handicap who was the Chairman of the drafting committee of the Constituent Assembly. There was Nehru	 one of the foremost architects of Free India	 who stood four square between caste suppression by the upper castes and the socialist egalitarianism implicit in secular democracy. These forces nurtured the roots of our constitutional values among which must be found the fighting faith in a casteless society	 not by obliterating the label but by advancement of the backward	 particularly that pathetic segment described colourlessly as Scheduled Castes and Scheduled Tribes. To recognise these poignant realities of social history and so to interpret the Constitution as to fulfil itself	 not eruditely to undermine its substance through the tyranny of literality	 is the task of judicial patriotism so relevant in Third World conditions to make liberation a living fact. The learned Attorney General drew our attention to the yawning gap between the legitimate expectations of the socially depressed SC & ST and their utter under representation in the Public Services except in such mean jobs as of scavengers and sweepers where no other caste was forthcoming. Equality of opportunity would be absent so long as equalisation strategy was not put into action	 and the State	 stage by stage and with great care and experimental eye	 took steps to secure the ends of articles 16(1) and 16(4)	 read in the light of the Preambular promise of equality	 fraternity and dignity	 the Part IV directive of promotion of educational and economic interests of the SC & ST and the Special Chapter	 especially article 336	 devoted to better representation of the SC & ST in the services and posts in connection with the affairs of the Union and States. We could not apprehend the social dimension of the stark squalour of SC&ST by viewing article 16 (4) through a narrow legal aperture but only by an apercu of the broader demands of social democracy	 without which the Republic would cease to be a reality to one fifth of Indian humanity. The final address to the Constituent Assembly by Dr. Ambedkar drives home this point	 not to interpret but to illumine the scheme of the equality code and the casteless society plea : The third thing we must do is not to be content with mere political democracy. We must make our political democracy a social democracy as well. Political democracy can 200 not last unless there lies at the base of it social democracy. What does social democracy mean ? It means a way of life which recognises liberty	 equality and fraternity as the principles of life. These principles of liberty	 equality and fraternity are not to be treated as separate items in a trinity. They form a union of trinity in the sense that to divorce one from the other is to defeat the very purpose of democracy. Liberty cannot be divorced from equality	 equality cannot be divorced from liberty. Nor can liberty and equality be divorced from fraternity. Without fraternity	 liberty and equality could not become a natural course of things. It would require a constable to enforce them. We must begin by acknowledging the fact that there is complete absence of two things in Indian society. One of these is equality. On the social plane	 we have in India a society based on the principles of graded inequality which means elevation of some and degradation for others. On the economic plane	 we have a society in which there are some who have immense wealth as against many who live in abject poverty. On the 26th January 1950	 we are going to enter into a life of contradictions. In politics we will have equality and in social and economic life we will have inequality. In politics we will be recognizing the principle of one man one vote and one vote one value. In our social and economic structure	 continue to deny the principle of one man one value. How long shall we continue to live this life of contradictions ? How long shall be continue to deny equality in our social and economic life ? If we continue to deny it for long	 we will do so only by putting our political democracy in peril. We must remove this contradiction at the earliest possible moment or else those who suffer from inequality will blow up the structure or political democracy which this Assembly has so laboriously built up (emphasis added). Indeed from another angle of vision	 article 16(4) serves to correct a gross social distortion and denial of human rights to whole groups ostracised by feudal history. A holistic concept of human rights includes among its components socioeconomic rights for	 without basic conditions of social justice	 survival with human dignity is an impossibility. Thus	 a great socioeconomic plan to uplift the harijan girijan groups is a must for living equality	 proclaimed by articles 14 to 16	 to become an active reality. It must be stated that the petitioners did not contest the need for State action to raise the lot of these backward most social sectors but objected	 its widespread 201 erosion of the right to basic equality which belongs to the have nots in the country. Where do we draw the line ? These are the disturbing issues going to the root of progressive nationalism raised by the writ petitioners and turned against them by the State	 but we are not inclined or entitled to venture into the political wisdom of governmental policies vis a vis 'backward ' community	 calculus save where constitutionality	 falling within the judicial jurisdiction	 confronts us. We must therefore confine the forensic focus to the specific issue of profound import projected by the aggrieved petitioners whose chief attack is against being passed over	 seniority and superior merit notwithstanding	 in favour of alleged neophytes or nitwits merely because	 by birth	 the latter belong to the SC&ST species	 trampling underfoot	 in the process	 the fundamental rights of equal opportunity entrenched in articles 14 and 16(1) of the Constitution. The dimensions of the problem	 the human numbers involved and the agitational potential said to be simmering in the civil services were vividly drawn at the bar by one side. The tragic tale of die hard decades of inequality even after Freedom	 the socioeconomic miles to go ' and the constitutional 'promises to keep ' (over which judges will not legally sleep) before the dalit brethren may break their chains and become at least distant neighbours to the less socially handicapped sector	 were highlighted pragmatically	 statistically	 hierarchically	 even desperately	 by the proponents of the impugned circulars (Annexures F to O covered by Prayers I to X). These submissions serve as poignant background but the decision on the vires of the Railway Board 's directives will depend on constitutional interpretation applied to Indian actualities	 not to idealised abstractions or theoretical possibilities. True	 the politicisation of casteism its infiltration into unsuspected human territories and the injection of caste consciousness in schools and colleges via backward class reservation are a canker in the rose of secularism. More positive measures of levelling up by constructive strategies may be the developmental needs. But the judicial process while considering constitutional questions	 must keep politics and administrative alternatives as out of bounds except to the extent economics	 sociology and other disciplines bear scientifically upon the proposition demanding court pronouncement. Here the sole issue	 spread out into the validity of the supposed sinful circulars (Annexures F to O covered by Prayers I to X) is whether article 16	 in its sweep and savings	 does permit State action in favour of socially and economically backward classes	 especially the constitutionally favoured category called the SC & ST	 to the point of liberal concessions slurring over 202 'age '	 'merit ' and the like	 not merely at the initial entrance gate but even at the higher promotional docks. Whether alternative policies should have been chosen by Government or would have served better to remove the handicaps of the SC & STs	 whether the advantages conferred on these classes are too generous and overly compassionate and whether the considerable numbers of the economically destitute receive the same sympathy as social have nots categorised as SC & ST these and other speculative maybes	 are beyond the courts orbit save where article 16 is hit by these omissions and commissions. Nor is it the court 's province to question the conscionableness or propriety of constitutional provisions which display ultra concern for members of the SC & ST. The court functions under the Constitution	 not over it	 interprets the Constitution	 not amends it	 implements its provisions	 not dilutes it through personal philosophy projected as constitutional construction. Objective tuned to constitutional wavelengths is our function and if only if constitutional guarantees have clearly been violated will the court declare as non est such governmental projects as go beyond the mandates of Part III read in harmony with Part IV. If	 on a reasonable construction	 the Administration 's special provisions under article 16(4) exceed constitutional limits	 it is the duty of the court to strike dead such project. Even so	 while viewing the legal issues we must not forget what is elementary that law cannot go it alone but must function as a member of the sociological ensemble of disciplines. If one out of a few reasonably tenable constructions of the constitutional provisions vis a vis the impugned executive directives may sustain the latter	 the court should and would refrain from using the judicial guillotine. There is a comity of coordinate constitutional instrumentalities geared to shared constitutional goals which persuades the judicature to sustain rather than slay	 save where the breach is brazen	 the transgression is plain or the effective co existence of the fundamental right and the administrative scheme is illusory. This Court has	 on former occasions	 upheld executive and legislative action hovering "perilously near" but not plunging into unconstitutionality (see In re: Kerala Education Bill (1959 SCR 995 at 1064). It is a constant guideline which we must vigilantly remember	 as we have stated earlier	 that our Constitution is a dynamic document with destination social revolution. It is not anaemic nor neutral but vigorously purposeful and value laden as they very descriptive adjectives of our Republic proclaim. Where ancient social injustice freezes the 'genial current of the soul ' for whole human segments our Constitution is not non aligned. Activist equalisation	 as a realistic strategy of 203 producing human equality	 is not legal anathema for articles 14 and 16. To hold otherwise is constitutional obscurantism and legal literalism	 allergic to sociologically intelligent interpretation. The Preamble which promises justice	 liberty and equality of status and opportunity within the framework of Secular	 Socialist Republic projects a holistic perspective. article 16 which guarantees equal opportunity for all citizens in matters of State Service inherently implies equalisation as a process towards equality but also hastens to harmonize the realistic need to jack up 'depressed ' classes to overcome initial handicaps and join the national race towards progress on an equal footing and devotes article 16(4) for this specific purpose. In a given situation of large social categories being submerged for long	 the guarantee of equality with the rest is myth	 not reality	 unless it is combined with affirmative State action for equalisation geared to promotion of eventual equality. Article 16(4) is not a jarring note but auxiliary to fair fulfillment of article 16(1). The prescription of article 16(1) needs	 in the living conditions of India	 the concrete sanction of article 16(4) so that those wallowing in the social quagmire are enabled to rise to levels of equality with the rest and march together with their brethren whom history had not so harshly hamstrung. To bury this truth is to sloganise article 16(1) and sacrifice the facts of life. This is not mere harmonious statutory construction of article 16(1) and (4) but insightful perception of our constitutional culture	 reflecting the current of resurgent India bent on making	 out of a sick and stratified society of inequality and poverty	 a brave new Bharat. If freedom	 justice and equal opportunity to unfold one 's own personality	 belong alike to bhangi and brahmin	 prince and pauper	 if the panchama proletariat is to feel the social transformation article 16(4) promises	 the State must apply equalising techniques which will enlarge their opportunities and thereby progressively diminish the need for props. The success of State action under article 16(4) consists in the speed with which result oriented reservation withers away as	 no longer a need	 not in the everwidening and everlasting operation of an exception [article 16(4)] as if it were a super fundamental right to continue backward all the time. To lend immortality to the reservation policy is to defeat its raison de 'etre; to politicise this provision for communal support and Party ends is to subvert the solemn undertaking of article 16(1)	 to costeify 'reservation ' even beyond the dismal groups of backward most people	 euphemistically described as SC & ST	 is to run a grave constitutional risk. Caste	 ipso facto	 is not class in a secular State. 204 The authentic voice of our culture	 voiced by all the great builders of modern India	 stood for abolition of the hardships of the pariah	 the mlecha	 the bonded labour	 the hungry	 hard working half slave	 whose liberation was integral to our Independence. To interpret the Constitution rightly we must understand the people for whom it is made the finer ethos	 the frustrations	 the aspirations	 the parameters set by the Constitution for the principled solution of social disabilities. This synthesis of ends and means	 of life 's maladies and law 's remedies is a part of the know how of constitutional interpretation if alienation from the people were not to afflict the justicing process. A statute rarely stands alone. Back of Minerva was the brain of Jove	 and behind Venus was the spume of the ocean. These broader observations are necessary to set our sights right	 to appreciate that our Constitution lays the gravestone on the old unjust order and the cornerstone of the new humane order. This constitutional consciousness is basic to interpretative wisdom. We may now start with the facts of the case and spell out the particular problems demanding our consideration. Constitutional questions cannot be viewed in vacuo but must be answered in the social milieu which gives it living meaning. After all	 the world of facts enlivens the world of words. And logomachy is not law but a fatal	 though fascinating	 futility if alienated from the facts of life. So	 before pronouncing on the legality of the impugned ten orders we must sketch the social setting in which they were issued and the socioeconomic facts which clothe article 16(4) with flesh and blood. 'The wisest in council	 the ablest in debate and the most agreeable companion in the commerce of human life	 is that man who has assimilated to his understanding the greatest number of facts. ' The facts The Indian Railways	 with an impressive record of expansion	 employs colossal numbers of servants in various typically hierarchical classes and grades. While the Indian Railways Act	 1890	 substantially regulates many of the functions of the railway administration in India	 the Railway Board is constituted under the 	 with a view more effectively to control the administration of railways. The Central Government is statutorily empowered 205 to invest the Railway Board with all or any of the powers and functions of the Central Government under the Indian Railways Act	 1890. Power is also given by section 2 to vest in the Railway Board the capacity to make general rules for railways administered by the Government. Of course	 the investment of powers upon the Railway Board is	 broadly speaking	 subject to the condition that the Central Government retains the ultimate authority in all matters connected with the Railway Administration. The Ministry of Home Affairs	 in the Government of India	 deals usually with all matters of personnel	 conditions of service of the Central Government staff and the like. Policy decisions regarding matters covered by article 16(4) apparently originate from the Ministry of Home Affairs and emanate to the various institutions like the Railway Board which responsively implement them. In the present case	 ten directives were issued by the Railway Board on different occasions	 which disclosed 'benign discrimination ' in favour of Scheduled Castes and Scheduled Tribes and are challenged by the petitioners as 'reverse discrimination '	 if we may use that expression popularised in American legalese. These directives were designed to protect and promote the interests of members of the SC & ST in the matter of their employment under the Indian Railway Administration and they specially related to the softer criteria for promotion. The Railway Board acted	 as is discernible from the relevant orders	 in obedience to the policy decisions of the Ministry of Home Affairs. Some argument was addressed on the validity of the Railway Board 's orders on procedural and other technical grounds. We see no substance in them. The Board was bound to carry out the Central Government 's directives under article 16(4) and did it. The broader issue of 'benign discrimination ' deserves close study. The meat of the matter	 to put it that way	 is the gross discrimination alleged to be implicit in the several Circulars of the Railway Board and the non applicability of article 16(4) to save these circulars. The focus of this litigation must primarily turn on that issue and the court must navigate towards egalitarian justice at the level of promotion posts in the public services	 keeping the land mark rulings of this Court as mariner 's compass. The disturbing perpetuation of socioeconomic suppression of a whole fifth of Indian manhood the dalits and the righteous resistance to prolonged 'reverse casteism ' resulting in deepening demoralization of the economically oppressed the soshits have been projected by counsel on the forensic screen as a conflict between equalisation and equality. Our founding fathers	 familiar with social dialectics and socialist enlightenment	 surely would have intended to bring both these have not categories together as a 206 broad brotherhood against the die hard Establishment and would never have contemplated a fratricidal strategy which would blind and divide brothers in distress the dalits and the soshits and harm the integration of the nation and its developmental march. Unless by dialectical approach sociologists lay bare this false dilema of dalits versus soshits	 the growing distrust in democracy will deepen	 the jurisprudence of constitutional revolution and egalitarian justice will fade in the books and the founding hopes of January 26	 1950	 will sour into cynical dupes of the masses	 decades after! Wider perspectives must	 therefore	 inform our study of the equality code (articles 14 to 16) to rid it of social contradictions and read into it the need for a dalit soshit partnership in demanding social justice. Felix Frankfurter set the judicial function when he said :(1) A Judge should be compounded of the faculties that are demanded of the historian and the philosopher and the prophet. The last demand upon him to make some forecast of the consequences of his action is perhaps the heaviest. To pierce the curtain of the future	 to give shape and visage to mysteries still in the womb of time	 is the gift of the imagination. It requires poetic sensibilities with which judges are rarely endowed and which their education does not normally develop. These judges must have something of the creative artist in them; they must have antennae registering feeling and judgment beyond logical	 let alone quantitative	 proof. Be that as it may	 the court must go to the constitutional basics for guidance	 decode the articles indifferent to agitational portents and ideological speculations	 but responsive to the urgent implementation of article 38 into the reality of Indian life. Article 38 reads: 38(1). The State shall strive to promote the welfare of the people by securing and protecting as effectively as it may a social order in which justice	 social	 economic and political shall inform all the institutions of the national life. (2) The State shall in particular	 strive to minimise the inequalities in income	 and endeavour to eliminate inequalities in status	 facilities and opportunities	 not only amongst individuals but also amongst groups of people residing in different areas or engaged in different vocations. (emphasis added) 207 The learned Attorney General	 while emphasising the egalitarian commitment of the Constitution over the whole range of public services throughout their career	 defended the impugned orders by law and logic	 pragmatics and statistics	 and countered the hypotheticals of the petitioners by the actual furnished by official facts and figures. He also relied on a few precedents	 in particular	 Rangachari 's case(1) and Thomas 's case(2) both of which bind this Bench. He also sought to explain away the effect of Balaji 's case(3) and Devadason 's case(4) on which the other side had heavily relied to nullify some of the circulars. The Union of India placed before us its case that notwithstanding measures for bringing the gap in the matter of gross under representation in the Administration	 no adequate improvement had been registered and	 and so	 more dynamic State action	 to fulfil its constitutional tryst with the frustrated fifth of the people described as SC & ST	 became necessitous. The raw reality of meagre harijan and girijan presence in the public services conscientised the Administration into taking a series of cautions steps to catalyse the prospects of these categories entering the many Departments of Government not merely at the initial stage but also at promotional points and in appointments to supervisory posts so as to become members of the higher echelons. The learned Attorney General contended that such affirmative actions	 slurring over fanatical and financial insistence on so called merit and seniority	 was in conformity with article 16(1) itself and	 in any case	 was protected by Art.16(4). Maybe	 the human numbers outside the SC & ST honestly suffer some meyhem in their career especially at the higher notches of promotion after long stagnation and are bitter that the shudra or panchama steals a march over him now	 although the poignant pages of earlier history have been a negation of personhood then for millions of the dregs of society	 desperately driving Dr. Ambedkar to vow "I shall not die a Hindu". But the synthesis of article 16	 not the antithesis between article 16(1) and article 16(4)	 gives the clue to creative constitutional construction. The learned Attorney General 's plea was that in a society of chronic inequality and scarcity of employment	 actual equality could never be midwifed without birth pangs	 and discriminatory unconstitutionality could not vitiate programmes meant to achieve real life 208 equality	 unless we took a pragmatic view. This approach is permissible if we follow Chief Justice Warren: Our judges are not monks or scientists	 but participants in the living stream of our national life	 steering the law between the dangers of rigidity on the one hand and of formlessness on the other. Our system faces no theoretical dilemma but a single continuous problem: how to apply to ever changing conditions the never changing principles of freedom. Let us draw the precise battle lines to contain the constitutional conflict within the actual limits. Equality of opportunity in matters of State employment is a constitutional guarantee and no citizen can be discriminated against on the score only of sex	 caste	 descent	 place of birth or residence. So	 one point pressed before us is that Scheduled Castes cannot be a favoured class in the public services because they are 'castes ' and cannot claim preference qua castes unless specially saved by article 16(4). And article 16(4) speaks of class	 not caste and the two are different	 however	 politically convenient the confusion may be. Another vital contention put forward by counsel for the petitioners was that article 16(4) could not apply to promotional levels. A third basic plea was that efficiency of administration was a constitutional consideration under article 335 and could not be a sacrificial goat to propitiate the backward class Kali. The impugned circulars offended against efficiency	 both by fomenting frustration among the Civil Services indirectly producing inefficiency and by manning higher posts which demand higher skills with men of lower competitive calibre and less experience in service thus posting 'efficiency risks ' in strategic positions violating article 335. The contentious issue is now clear. Are SC & ST mere castes within the sense of article 16(2) ? If so	 can article 16(4) help these castes through rule of promotional partiality ? And	 in any case	 can article 16(4) rescue rules of benign discrimination if the impact thereof is generation of gross inefficiency in administration ? Is not economic 'have notism ' a better yardstick of backwardness in secular India? A brief resume of the structure of the Railway Services may help understand the rival arguments in their precise setting. The pyramid begins	 at the base	 with Class IV posts and rises to the apex	 by stages	 through Class III	 Class II and Class I. True to our hierarchical culture	 pervasive in Indian Services	 there are further sub divisions	 consisting of many categories in each class and many grades in each category. The agencies for recruitment are the Union Public Service 209 Commission	 the Railway Service Commission and the top officers authorised by the Railway Board in this behalf. Ordinarily the first entry into each category is filled by direct recruitment	 if we may use language loosely. Thereafter	 appointments to higher grades/categories are usually by promotion. The promotional processes are traditionally two fold	 viz.	 (a) by departmental selection based on merit cum seniority	 and (b) by escalation	 in the order of seniority	 from the lower to the higher grade/category	 subject	 of course to being weeded out if found unfit. Candidates belonging to SC&ST receive certain pronounced advantages both at the stage of initial recruitment and later at the promotion stage. The Indian Railway Establishment Manual a compendious collection of rules and directions bearing on the conditions of employment of railway personnel	 sets out all the information. Speaking population wise and in approximate terms	 the Scheduled Castes constitute about 15% and the Scheduled Tribes 7 1/2%. Broadly based on the ratio of the strength of SC&ST to the whole population	 the Railway Administration provided for reservation for candidates belonging to the SC&ST. This percentage of reservation applied to Class IV	 Class III	 Class II and	 in a limited way	 to Class I posts. The reservation is worked out by the method known as 40 point roster. These special provisions notwithstanding the intake of these communities	 stagnating at the bottom of the Indian policy	 continued to be chronically niggardly. To increase the rate of absorption of SC&ST into the services	 further facilities	 concessions and relaxations were offered from time to time. Despite these seemingly attractive employment opportunities the dismal backwardness in the matter of representation in administration from among the SC&ST was such that the vacancies reserved for them remained	 in many cases	 unfilled by SC & ST candidates. Lest the overall representation of the members of the SC&ST should continue deplorably negligible Government adopted a policy of "carry forward"	 for upto three recruitment years	 of reserved vacancies if enough number of candidates from the said groups did not get selected. The "carry forward" rule was calculated to keep open reserved vacancies for at least three years so that the under representation could be made up at least in part. Homogenisation of the dalits into the national mainstream was regarded as vital to our democracy by the State and these positive strategies of special opportunities vis a vis SC&ST had	 as its raison d 'etre	 only the imperative need to exercise the haunting spectre of the socially and economically suppressed species and to abolish the utter squalour of SC&ST so that the community at large could march ahead without haggard groups dragging their feet. Social conscience considers balanced democratic development as the humane justification for selective discrimination. 210 With this backdrop	 we may epitomise the ten 'tainted ' directives and scan them for their unconstitutionality. Special provisions for depressed classes and even other castes have a pre constitution history. After the Constitution was enacted the legality of old rules based on caste became moot and the Central Government revised its policy. The post Constitution re incarnation of the communal G.O. concentrated not on caste orientation but on elimination of socioeconomic suppression and the diverse ways to achieve this objective. We must remember	 in this context	 not merely the four classes of Service but also the broad division of the staff into selection and non selection posts. The first policy statement of the Union of India on the issue of better representation of SC&ST in Government Service begins with Resolution No. 42/21/49 NG 8 of September 13	 1950. To understand the functional compulsions	 purpose	 orientation and constitutional parameters relevant to such a policy formulation we have to refer to a few articles of the Constitution. Articles 14 to 16 form a code by themselves and embody the distilled essence of the Constitution 's casteless and classless egalitarianism. Nevertheless	 our founding fathers were realists	 and so did not declare the proposition of equality in its bald universality but subjected it to certain special provisions	 not contradicting the soul of equality	 but adapting that never changing principle to the ever changing social milieu. That is how articles 15(4) and 16(4) have to be read together with articles 15(1) and 16(1). The first sub article speaks of equality and the second sub article amplifies its content by expressly interdicting caste as a ground of discrimination. Article 16(4) imparts to the seemingly static equality embedded in article 16(1) a dynamic quality by importing equalisation strategies geared to the eventual achievement of equality as permissible State action	 viewed as an amplification of article 16(1) or as an exception to it. The same observation will hold good for the sub articles of article 15. Thus we have a constitutional fundamental guarantee in articles 14 to 16; but it is a notorious fact of our cultural heritage that the Scheduled Castes and the Scheduled Tribes have been in unfree Indian nearly dehumanised	 and a facet of the struggle for Freedom has been the restoration of full personhood to them together with the right to share in the social and economic development of the country. Article 46 is a Directive Principle contained in Part IV. Every Directive Principle is fundamental in the governance of the country and it shall be the duty of 211 the State to apply that principle in making law. Article 46	 in emphatic terms	 obligates the State. "to promote with special care the educational and economic interests of the weaker sections of the people	 and	 in particular	 of the Scheduled Castes and Scheduled Tribes	 and shall protect them from social injustice and all forms of exploitation. Reading article 46 together with article 16(4) the luscent intent of the Constitution framers emerges that the exploited lot of the harijan girijan groups in the past shall be extirpated with special care by the State. The inference is obvious that administrative participation by SC&ST shall be promoted with special care by the State. Of course reservations under article 16(4) and promotional strategies envisaged by article 46 may be important but shall not run berserk and imperil administrative efficiency in the name of concessions to backward classes. Article 335 enters a caveat in this behalf: 335. The claims of the members of the scheduled Castes and the Scheduled Tribes shall be taken into consideration consistently with the maintenance of efficiency of administration	 in the making of appointments to services and posts in connection with the affairs of the Union or of a State. The positive accent of this Article is that the claims of SC&ST to equalisation of representation in services under the State	 having regard to their sunken social status and impotence in the power system	 shall be taken into consideration. The negative element	 which is part of the Article	 is that measures taken by the State	 pursuant to the mandate of articles 16(4)	 46 and 335	 shall be consistent with and not subversive of "the maintenance of efficiency of administration". Within this broad constitutional framework the Central Government worked out its policy	 way back in 1950	 and made subsequent alterations in keeping with the needs of the situation	 the poor progress registered	 the militant impatience of the affected SC&ST and the improved tactics to hasten abolition of the depressed status of these groups by effective equalisation with the rest. Even here	 it may be noticed that the Constitution has given a special position for the Scheduled Castes and the Scheduled Tribes. Article 341 makes it clear that a 'Scheduled Caste ' need not be a 'caste ' in the conventional sense and	 therefore	 may not be a caste within the meaning of articles 15(2) or 16(2). Scheduled Castes become such only if the President specifies any castes	 races or tribes or 212 parts or groups within castes	 races or tribes for the purpose of the Constitution. So	 a group or a section of a group	 which need not be a caste and may even be a hotchpotch of many castes or tribes or even races	 may still be a Scheduled Caste under article 341. Likewise	 races or tribal communities or parts thereof or part or parts of groups within them may still be Scheduled Tribes (article 342) for the purpose of the Constitution. Under this definition	 one group in a caste may be a Scheduled Caste and another from the same caste may not be. It is the socioeconomic backwardness of a social bracket	 not mere birth in a caste	 that is decisive. Conceptual errors creep in when traditional obsessions obfuscate the vision. This aspect has been referred to in the State of Kerala vs N. M. Thomas by me	 and dealt with at more length by Ray	 C.J.: Scheduled Castes and Scheduled Tribes are not a caste within the ordinary meaning of caste. In Bhaiyalal vs Hari kishan Singh and Ors.(2) this Court held that an enquiry whether the appellant there belonged to the Dohar caste which was not recognised as a Scheduled Caste and his declaration that he belonged to the Chamar caste which was a Scheduled Caste could not be permitted because of the provisions contained in Article 341. No Court can come to a finding that any Caste or any tribe is a Scheduled Caste or Scheduled Tribe. Scheduled Caste is a caste as notified under Article 366(25). A notification is issued by the President under Article 361 as a result of an elaborate enquiry. The object of Article 341 is to provide protection to the members of Scheduled Castes having regard to the economic and educational backwardness from which they suffer. The President notifies Scheduled Castes not with reference to any caste characteristics but their abysmal backwardness	 as is evident from the scheme of Part XVI. He appoints	 under article 338	 a Special Officer whose duty is to investigate into all matters relating to safeguards for the SC&ST. The Constitution provides not merely for adequate representation of SC&ST to services and posts under the Union and States	 but also provides for reservation of seats for SC&ST in the Legislatures. The cursory study of the Articles relating to the status and safeguards of SC&ST puts it beyond doubt that the founding fathers have assigned to them a special place and shown towards them special concern and charged the State with special mandates to redeem 213 these handicapped human sectors from their grossly retarded situation. Indeed	 they are not merely backward	 but are the backwardmost and cannot be equated with just any other caste in the Hindu fold. It is	 therefore	 problematic whether article 16(2) when it refers to equality among castes deals with the Scheduled Castes which	 as shown above	 may even be made of a plurality of castes or groups or races and may vary from State to State. Also	 a caste	 subjected qua caste	 to the most humiliating handicaps may be a backward class although the Court will hesitate to equate caste with class except where the degree of dismalness is dreadful. The relevance of this point will be clear when we deal with the legal submissions of counsel. We will now state	 in an abbreviated form	 the various measures of the Railway Board (in response to decisions of the Ministry of Home Affairs) for reservation in services of SC&ST. After noting the policy of communal representation in the Services before the Constitution and the constitutional ban on discrimination by way of reservation on the ground of caste save in the case of SC&ST (and in some cases Anglo Indians with whom we are unconcerned here) the Home Ministry proceeded to spell out the new stance: Pending the determination of the figures of population at the Census of 1951 the Government of India have decided to make the following reservations in recruitment to posts and services under them: (a) Scheduled Castes: The existing reservation of 12 1/2 % of vacancies filled by direct recruitment in favour of the Scheduled Castes will continue in the case of recruitment of posts and services made	 on an all India basis by open competition	 i.e. through the Union Public Service Commission or by means of open competitive test held by any other authority. Where recruitment is made otherwise than by open competition the reservation for Scheduled Castes will be 16 2/3 as at present. (b) Scheduled Tribes: Both in recruitment by open competition and in recruitment made otherwise than by open competition there will be a reservation in favour of members of Scheduled Tribes of 5% of the vacancies filled by direct recruitment. Under the Constitution all citizens of India are eligible for consideration for appointment to posts and services under the Central Government irrespective of their 214 domicile or place of birth and there can be no recruitment to any Central Service which is confined by rule to the inhabitants of any specified area. In practice however recruitment to class I and II services and posts is likely to attract candidates from all over India and will be on a truly all India basis	 while for the majority of Class III services & posts which are filled otherwise than through the Union Public Service Commission only those residing in the area or locality in which the Office is located are likely to apply. In the latter class of cases the percentages of reservations for Scheduled Castes and Scheduled Tribes will be fixed by Government taking into account the population of the Scheduled Castes and Scheduled Tribes in that area. Reservations were excluded for promotions and minimum qualifications were a 'must '. But age relaxation by 3 years (from the maximum fixed for others) was allowed. This policy is not challenged as unconstitutional and rightly so. However	 this special provision showed only minimal concessions to SC&ST	 being the first cautious	 conservative	 post constitutional measure under article 16(4). But law is what law does. Did this reluctant relaxation only on a few grounds work? Constant monitoring of law in action	 with an eye on the end result	 is social engineering. The goal here was to awaken the sleeping soul and harness the harijan resource by mainstreaming techniques constitutionally sanctioned. The policy proved non viable and a change of strategy was called for and by Annexure D the Railway Board altered the rules "with a view to securing increased representation of Scheduled Castes and Scheduled Tribes in the Railway Services". At the instance of the Home Ministry the Railway Board decided on 5 10 1955 that more realistic relaxations were needed and authorised recruiting bodies to slur over low places obtained by the SC&ST candidates: . .except where such authority considers that the minimum standard necessary for the maintenance of efficiency of the administration has not been reached. Whenever candidates are selected in this manner	 the appointing authorities will make necessary arrangements to give additional training and coaching to the recruits so that they might come up to the standard of other recruits appointed along with them. The anxiety to level up the lowly human layers by special training so as to maintain administrative efficiency is evident in this directive. 215 Likewise	 where direct recruitment	 otherwise than by examination was provided for	 taking of SC&ST candidates '. . fulfilling a lower standard of suitability than from other communities	 was permitted so long as the candidates have the prescribed minimum education and technical qualifications and the appointing authorities are satisfied that the lowering of standards will not unduly affect the maintenance of the efficiency of administration. ' Here again	 obsession with 'efficiency ' is manifest. Then comes what is called the 'carry forward ' rule: (3)(a) if a sufficient number of candidates considered suitable by the recruiting authorities	 are not available for the communities for whom reservations are made in a particular year	 the unfilled vacancies should be treated as unreserved and filled by the best available candidates. The number of reserved vacancies thus treated as unreserved will be added as an additional quota to the number that would be reserved in the following year in the normal course	 and to the extent to which approved candidates are not available in that year against this additional quota	 a corresponding addition should be made to the number of reserved vacancies in the second following year. * * * * (b) In the event of suitable Scheduled Caste candidate not being available	 a Scheduled Tribe candidate can be appointed in the subsequent reserved vacancy and vice versa subject to adjustment in the subsequent points of the roster. The quota for two years	 if carried forward	 would not materially affect the stream of 'merit worthy ' candidates	 nor substantially diminish the prospects of non SC&ST candidates in a given year. So the Railway Board introduced the principle consistently with article 335. Government moved further because real power could be shared by the weakest sections only if the doors of the higher decks were pened to them. The higher echelons are the real controllerates	 not the menial levels	 hierarchically structured as our society is. Obviously	 article 16(4) was not designed to get more harijans into Government as scavengers and sweepers but as 'officers ' and 'bosses '	 so that administrative power may become the common property of the high and low	 homogenised and integrated into one community. Social stratification	 216 the bane of the caste system	 could be undone and vertical mobility won not by hortative exercises but by experience of shared power. Viewed thus	 the 'open sesame ' strategy for entry into superior cadres could only be by extending concessions at higher levels of 'promotions '. Annexure D did not make reservations for SC&ST for promotion posts	 but merely asked for sympathy on the part of promoting authorities. Lachrymal exercises	 even in government directives	 are in practice	 little more than skin deep; and elitist alibis	 when the ancient anguish of the lowliest & the lost besieges the citadels of the status quo	 readily checkmate ameliorative moves. The harijan lot	 in administrative services at the promotional levels	 remained a paper hope	 a teasing illusion and a promise of unreality. Article 46	 whether we like it or not	 ordains that the State shall 'with special care ' promote the interests of the SC&ST. And so long as the harijan girijan remained an alien to the Civil Service and the janitors for the higher chambers of Administration were themselves non harijan girijan gentlemen	 he would be a naive sociologist who thought that mere plea for more sympathy made in official orders would work magic. Government	 on a performance audit of its policy of 'no reservation ' for promotion posts	 discovered that the harijan could hardly reach higher positions. More effective methods were needed. A radical change in policy was effected by the Railway Board through Annexure F of April 27	 1959. 'Merit '	 sanctified by tradition	 lost the battle. 'Tradition is a great retarding force	 the vis inertiae of history; ' and so	 heroic measures of progressive thrust	 the Railway Board realised	 alone could effect the break through and bring the harijan girijan groups into the higher brackets of Administration Annexure was promulgated providing for reservation in promotions. This has been challenged before us. The tepid provision opening up promotion posts for 'reserved ' categories was first confined to Class III and Class II	 Class I being too sacrosanct to be soiled by meritless members. Annexure F reads: Sub: Reservation for members of Scheduled Castes and Scheduled Tribes in posts filled by promotion in Railways. Reference is invited to Board 's letter No. E55CMI/3 dated 5 10 55. The Railway Board have	 in partial modification of para IV of the above letter	 decided as follows: (a) Promotion from Class IV to Class III and from Class III to Class II. 217 The Railway Board have decided that promotions from Class IV to Class III and from Class III to Class II service are of the nature of direct recruitment and the prescribed quota of reservation for Scheduled Castes and Scheduled Tribes should be provided as in direct recruitment. The field of eligibility in the case of Scheduled Castes and Scheduled Tribes candidates should be four times the number of posts reserved without any condition of qualifying period of service in their case	 subject to the condition that such consideration should not normally extend to staff beyond two grades immediately below the grade for which the selection is held. This reservation was confined to 'selection posts ' and the circular was explicit that "there will be no quota for Scheduled Castes and Scheduled Tribes candidates in respect of promotion to "non selection" posts. For "general posts" of certain types in Class III	 it was laid down: (c) "General Posts" in Class III. There are certain other types of posts on Railways such as Passenger Guides	 Welfare Inspectors	 Safety Inspectors Platform Inspectors	 Publicity Inspectors	 Vigilance Inspectors	 etc.	 which are ex cadre posts filled by drawing staff from more than one branch. Filling of these posts is in the nature of direct recruitment and the reservation for Scheduled Castes and Scheduled Tribes as applicable to direct recruitment should be applied. " More chances to pass tests	 additional training and coaching to raise the standard of the sub standard were also provided for in the Board 's order. Homage was thus paid to the 'administrative efficiency ' component of article 335. This departure regarding reservation at the promotion tier for selection posts was challenged before this Court but upheld in Rangachari 's case. We will dwell at some length on that ruling later but we may merely mention than an appeal was made to us by counsel for the petitioners that we should reconsider	 by reference to a larger bench	 the ratio of Rangachari which has been approvingly referred to for nearly two decades by this Court	 acted upon by Government throughout and enjoys	 if we may say so with great respect	 our full concurrence. Constitutional propositions on which a whole nation directs its destiny are not like Olympic records to be 218 periodically challenge and broken by fresh exercises in excellence but solemn sanctions	 with judicial seal set thereon	 for the country to navigate towards the haven of human development for everyone. To play cross word puzzle with constitutional construction is to profane it	 unless	 of course	 a serious set back to the progress of human rights or surprise reversal of constitutional fundamentals has happened. We find the question discussed	 decided and consistently followed since Rangachari and see no reason to open the Pandora 's box. So it was that we rejected the plea for reconsideration. Even so	 the alternative method of containing Art	 16(4) within the contours of Rangachari was open to counsel and that has been done in argument as will be evident from the discussion on the vires of the subsequent orders of the Board. All the fire was turned by petitioners ' counsel on promotion 'excesses ' through Railway Board circulars. Annexure H of August 27	 1979 is one such: Annexure H The Railway Board have now revised their policy in regard to reservation and other concessions to Scheduled Castes and Scheduled Tribes in posts filled by promotion. The particular concessions are concretised thus: (B) Promotion by selection method (i) Class II appointments: In promotion by selection from Class III to Class II	 as a measure of improving representation of Scheduled Castes/ Scheduled Tribes	 it has now been decided that	 if they are within the zone of eligibility the Scheduled Caste and Scheduled Tribe employees will be given	 by the Selection/Departmental promotion Committee	 one grading higher than the grading otherwise assignable to them on the basis of their record of service i.e. if any Scheduled Caste or Scheduled Tribe employee has been categorised by the Committee	 on the basis of his record of service as "Good"	 he should be recategorised by the Committee as "Very Good". Likewise	 if any Scheduled Caste or Scheduled Tribe employee is grades as "Very Good" on the basis of his record of service	 he will be recategorised by the Committee as "Outstanding". Of course	 if any Scheduled Caste or Scheduled Tribe employee has already been categorised by the Committee as "Outstanding" on the basis of his record of service	 no recategorisation will be needed in his case. This recategorisation will then 219 form the basis of allotment of marks in respect of 'Record of service '. The above concession would be confined to only 25 per cent of the total number of vacancies in a particular grade or post filled in a year. In the matter of selection to Class III and Class IV posts the concession runs thus: There will be reservation of 12 per cent and 5 per cent of the vacancies for Scheduled Castes and Scheduled Tribes respectively in promotions made by selection in or to Class III and Class IV posts	 in grades or services in which the element of direct recruitment	 if any	 does not exceed 50 per cent. Promotion against reserved vacancies will continue to be subject to the candidates satisfying the prescribed minimum qualifications and standards of fitness. It has also been decided that in respect of promotions to selection posts in Class III where safety aspect is not involved	 the qualifying marks under "Professional ability" in respect of Scheduled Caste and Scheduled Tribe candidates should be 25 out of 50 instead of 30 out of 50 as applicable to the candidates belonging to the unreserved groups. Similarly	 qualifying marks in aggregate in respect of Scheduled Castes and Scheduled Tribes should be 50 out of 100 instead of 60 out of 100 for others. It must be noticed that while grading has been modified and qualifying marks reduced as indicated above	 for SC&ST	 care has also been taken to exclude from these concessions	 posts which involve "safety aspects" and not to relax prescribed minima of qualifications and standards of fitness. Article 335 has been honoured	 making a margin on merit inevitable when choosing the second best. The next Order assailed by counsel is that of 20th April 1970 (Annexure I) and its highlights are revealed by relevant excerpts: ANNEXURE I The policy of the Government of India in regard to reservations for Scheduled Castes and Scheduled Tribes in posts and services under the Government of India was laid down in the Ministry of Home Affairs Resolution No. 42/21/49/NGS dated 13th September	 1950 circulated with Railway Board 's letter No. E47CMI/49/3 dated 23rd December	 1950. The question of revising the percentages 220 of reservation for Scheduled Castes and Scheduled Tribes in post and services under the Government of India in the light of the population of these communities as shown in the 1961 census has been under consideration of the Government for some time. It has now been decided in modification of the decisions contained in paras 2 and 4(1) of the Ministry of Home Affairs ' Resolution dated 13th September 1950	 that the following reservations will hereafter be made for the Scheduled Castes and Scheduled Tribes in posts and services which are filled by direct recruitment; What are they? 12% and 5% are raised to 15% and 7% respectively for SCs and STs	 consequent on the census picture and population ratio. Likewise	 in local or regional recruitments (presumably	 they are inferior posts) the population ratio prevalent in the concerned States was to be the basis for reservation quota for SC&ST. By the same order	 the "carry forward" rule was carried a little further forward by increasing it	 in the absence of suitable candidates from SC&ST	 from 2 to 3 years. It was also provided that the reserved vacancies	 if candidates were available (and vice versa) could well be filled by them	 instead of being thrown open to the general community. The Board 's letter dated April 29	 1970 made a further change by revising the roster. Positions Nos. 1	 4	 8	 14	 17	 22	 28	 36 were to go to SC/ST candidates. The Note takes care to avoid total deprivation of changes for a particular year for general candidates when the vacancies are few: NOTE: If there are only two vacancies to be filled in a particular year	 not more than one may be treated as reserved and if there be only one vacancy	 it should be treated as unreserved. If on this account	 a reserved point is treated as unreserved the reservation may be carried forward to the subsequent three recruitment years. Similar provisions	 though somewhat different in detail	 were made for posts filled by direct recruitment otherwise than by open competition. A big break with the past was next made by the Board 's proceedings of 11 1 1973 (Annexure K) which hurt the lower classes of employees whose promotion was regulated by seniority cum suitability (i.e.	 non selection posts	 according to official jargon). That directive states: 221 ANNEXURE K After careful consideration the Board have now decided that a quota of 15% and 7 1/2% for Scheduled Castes and Scheduled Tribes respectively may also be provided in promotion to the categories and posts in Class I	 II	 III and IV filled on the basis of seniority cum suitability provided the element of direct recruitment to those grades	 if any	 does not exceed 50%. The number of reserved vacancies in a recruitment year (viz.	 financial year on the Railways) should be determined under Board 's letter No. E(SCT) 70CM15/10 dated 20 4 70. . . In the case of reserved community candidates equal to the number of reserved vacancies are not found suitable for promotion even with relaxed standard	 the reserved vacancies may be dereserved after following the procedure prescribed for dereservation as in the case of selection categories. The quota so dereserved will be carried forward to three subsequent recruitment years; the year in which no panel is formed is not to be taken into account for this purpose. This order has been fiercely attached as unconstitutional. The order attached in Rangachari 's case (supra) related to selection posts at the promotion level but Annexure K (11 1 1973) covers promotion to non selection posts. The whole gamut of promotions in Classes II	 III and IV areas thus comes under the reservation formula. Annexure I extended the principle of reservation to lower ranks of Class I services (i.e. Junior Class I scale). The 'carry forward ' project	 calculated to ensure adequate representation by broadening the time zone to three years	 was applicable to all cases of reservations in promotion posts. One of the major broadside attacks made on the validity of the Railway Board 's circulars was the serious peril to administrative efficiency	 a non negotiable value under article 335. The hazards to railway travel	 it was urged	 would so increase because of the harijan component and its sub standard performance that rail road accidents would escalate and threaten human life! We must	 by way of antidote to this caricature	 notice	 however	 that provisions for special training and coaching where the recruit was somewhat sub standard	 was specially insisted on and this	 at least partially	 overcame the 222 'awesome ' deficiency. No factual material to blame all the ills of the Indian Railways on the reservation policy was placed before us except a hunch in a Report to be referred to later. If harijans were excluded would railway accidents have a long holiday ? Courts are not credulity in robes ! A comprehensive programme of balancing administrative competency with adequacy of SC&ST representation was attempted by the Railway Board in Annexure M which provided for in service training for candidates who were below standard. This letter of the Board dated 31st August 1974 recalled the earlier letter of 27 4 1959 which provided: While filling the posts on promotion	 however	 candidates of three communities should be judged in a sympathetic manner and arrangements made where necessary to give to such staff additional training and coaching	 to bring them upto the standard of others. In the light of actual experience and the complex of considerations implied in articles 16(4)	 46 and 335 the Board directed	 with disturbing concern for the continued exclusion of SC&ST candidates	 as follows: The matter has been further considered by the Board and it has been decided that if	 during the selection proceedings it is found	 that the requisite number of Scheduled Caste and Scheduled Tribe candidates are not available for being placed on the panel in spite of the various relaxations	 already granted	 the best among them i.e. who secure highest marks	 should be earmarked for being placed on the panel to the extent vacancies have been reserved in their favour. The panel excluding the names of such persons may also be declared provisionally. Thereafter the Scheduled Caste and Scheduled Tribe candidates who have been so earmarked may be promoted ad hoc for a period of six months against the vacancies reserved for them. During the said six months period	 the Administration should give them all facilities for improving their knowledge and coming upto the requisite standard	 if necessary by organising special coaching classes. At the end of the six months period	 a special report should be obtained on the working of these candidates and the case put up by the Department concerned to the General Manager through SPO(RP) for a review. The continuance of the Scheduled Caste and Scheduled Tribe candidates in the 223 higher grades would depend upon this review. If the candidates are found to have come upto the requisite standard	 their names would be included in the panel and the vacancies dereserved and filled in the usual manner by candidates from other communities. The procedure indicated in the preceding para would also apply to promotion to the posts filled on the basis of seniority cum suitability	 with the only difference that the Review at the end of the six months period would be carried out by the authority competent to approve the Select List. This directive takes good care of harijan girijan obtuseness	 if any. We move on to Annexure N of February 21	 1976 which relates to carrying forward of reserved vacancies remaining unfilled. We need not go into its details except to state that further facilities are offered to SC&ST promotees	 on account of unsatisfactory intake as a fact. Although on paper what might appear to be pampering concessions were offered to SC&ST candidates	 the painful reality	 according to the Union of India	 was alarming under representation and utter inadequacy of SC&ST personnel in the Railway Services. Arithmetical manipulations and national concessions incorporated in government proceedings did not impact on the raw life of depressed classes unless activist tactics of upgrading the competence and awareness of those human sectors were fruitfully carried out in a result oriented manner. The Union of India and the Railway Board apparently pinned their faith on increasing the percentage hoping that thereby more harijans would be attracted. The twin reservations of 15% and 7 1/2% for the SCs and STs to be filled by promotion in Class I	 II	 III and IV services	 whereby seniority cum suitability or selection on the strength of competitive examinations	 had all along been limited in such manner as not to exceed 50%	 even on the application of the 'carry forward ' formulae. Since this did not ensure fair representation	 a change was contemplated by Annexure O: The question of enlarging the scope of the existing scheme of reservation for Scheduled Castes and Scheduled Tribes in the aforesaid cases has been under the consideration of the Government of India for some time past and in partial modification of the instructions contained in the above letters it has now been decided that henceforth the reservations in posts filled by promotion under the existing scheme as indicated above would be applicable to all grades or services where 224 the element of direct recruitment	 if any	 does not exceed 66 2/3% as against 50 per cent as at present. What was done was to raise the maximum from 50% to 66 2/3% its vice	 writ on its face according to counsel 's argument being promotion of inefficiency along with promotion of SC&ST appointees. The furious charges of inefficiency in Administration	 injected by incompetence imported through SC&ST candidates and by frustration and demoralisation of the non SC&ST members who were passed over by their less competent juniors	 was sought to be supported by reliance on the Report of the Railway Accidents Enquiry Committee 1968. There was reference in it to discontent among supervisors inter alia on account of the procedure of reservation of posts for SC&ST. It is true that the Report has a slant against the SC&ST promotion policy notwithstanding the assurance given by the Railway Board to the Committee that instructions had been issued not to relax standards in favour of SC&ST members where safety was involved. We need hardly say that it is straining judicial gullibility to breaking point to go that far. This is an argumentum an absurdum though urged by petitioners with hopeful ingenuity. Nor are we concerned with certain newspaper items and representations about frustration and stagnation. On the other hand	 the plea	 forcefully put forward that economic backwardness should be the touchstone of any reservation policy in a secular	 socialist republic may merit better examination. Surely	 extraneous factors	 however passionately projected	 cannot shake or shape judicial conclusions which must be founded on constitutional criteria and relevant facts only. What then is the defence of the Union to the charge of departure from equal treatment for all citizens alike ? What is the principle derivable from the precedents on the points raised ? A technical point is taken in the counter affidavit that the 1st petitioner is an unrecognised association and that	 therefore	 the petitioner to that extent	 is not sustainable. It has to be overruled. Whether the petitioners belong to a recognised union or not	 the fact remains that a large body of persons with a common grievance exists and they have approached this Court under article 32. Our current processual jurisprudence is not of individualistic Anglo Indian mould. It is broad based and people oriented	 and envisions access to justice through 'class actions '	 'public interest litigation '	 and 'representative proceedings '. Indeed	 little Indians in large numbers seeking remedies in courts through collective proceedings	 instead of being driven to an expensive plurality of litigations	 is an affirmation of participative justice in our democracy. We have no hesitation in holding that the narrow concept 225 of 'cause of action ' and 'person aggrieved ' and individual litigation is becoming obsolescent in some jurisdictions. It must fairly be stated that the learned Attorney General has taken no objection to a non recognised association maintaining the writ petitions. The case of the Union of India is that articles 46	 335	 16(1) and 16(4) must be taken as a constitutional package and not read in isolation. In that view	 the policy of reservation is geared to equalisation of opportunities for employment and	 therefore	 a fulfillment of article 16(1). Reading the two sub articles as complementary to each other and giving a wider connotation to the expression "appointment"	 the learned Attorney General sought to include in its semantic circle appointments by way of promotion	 deputation	 transfer and on contract. On this footing	 it was urged that article 16(4) completely protected the various directives regarding appointments by promotion. It is the case of the Government that SC&ST have all along suffered social and economic deprivation and utter under representation in the Government service. Naturally	 reservation to boost the chances of the SC&ST in Government services had to be resorted to as a pragmatic policy of levelling up. Having regard to administrative efficiency and other social factors	 Government had been reviewing the position from time to time and had tailored its reservation policy to fit the needs of a given service or state of affairs. The stand of the State is that . once the Government have decided after reviewing the overall position of representation of Scheduled Castes/Scheduled Tribes in Government Services that the reservation principles should continue in certain types of appointments	 the reservation of a certain number of vacancies have to be provided	 irrespective of whether Scheduled Castes/Scheduled Tribes are already duly represented or not in specific cadres of the Services. Although Rangachari 's case covered only selection posts	 the Union of India took the view that the same principle held good for nonelection posts also. In fact	 if at all the prospects of SC&STs in Government Service were to be improved	 it had to begin with non selection posts. They are the lower categories where the members of the SC&ST have a chance. Provision of reservation in Class I services would be theoretically attractive to SC&STs but not so much in practice. . reservation in promotional appointments made by means of seniority cum suitability is necessary because the 226 Scheduled Castes/Scheduled Tribes who generally occupy the lower positions in the recruitment/promotional panels cannot get further promotion at all or as per the requisite percentage alongwith other employees because of their very low position in the seniority list The submission of the Central Government is that not with standing the extension of the principle of reservation	 the presence of harijans and girijans is sparse. In this connection	 an extract from the half yearly report of the Ministry of Railways for the period ending 31 3 1978 showing the representation of the Scheduled Castes and Scheduled Tribes in the various Railway Services presented to the Parliament by the Government is reproduced below. The table furnished as in 1978 shows that Scheduled Castes have in Class I around 7% representation	 in Class II 9.5%	 in Class III 11.1% and even in Class IV (excluding safaiwalas) only 18%. Safaiwalas	 who are menials like scavengers and sweepers	 are mostly drawn from harijans since other communities consider such jobs infra dig. So	 there is 83% representation of SCs among safaiwalas. This is not because of representation but because no one else is forthcoming for such 'untouchable ' jobs. The Scheduled Tribes have a more pathetic tale to tell. In Class I services they have 1% representation	 in Class II	 1.8%	 in Class III	 2.2% and in Class IV (excluding safaiwalas) 5.1% and even among safaiwalas only 1.5%. On the basis of these statistics the Railway Board 's case is that adequacy of representation for SC&STs even according to their population (forgetting centuries of total exclusion) is a long way off. These official figures culled from the Reports of the Commissioner for Scheduled Castes and Scheduled Tribes are for employment in Central Govt. not confirmed to the Railways	 and reveal how a square deal to SCs and STs may take centuries	 observing the current snail 's pace in the intake. Social realists will read these pessimistic figure of the last ten years which prove the myth and negate the neurotic rhetoric about the SC&ST communities having cornered all the posts in the Central Government from Chaprasi to Secretary	 accelerating there by the impending calamity of administrative collapse due to the disproportionate presence of the 'inefficient ' social components! A mere formula of reservation is not the factum of recruitment. That is 227 morbid fancy. The truth is that more aggressive policies than paper reservations are the need if equality and excellence are the creed. Reservation is but one strategy and historically has established itself. More must be done by a complex of processes by which harijans/girijans will get boosted in 'capabilities '	 and mainstreamed to share in the Civil Service cake. The poor annual assimilation into the public employment sector of the weakest social segments makes a tragic mockery of the statistical jugglery of harijan monopoly. Any theory or formula is best tested by how it works	 not by how it is worded. Nikita Kruschev once remarked: ". a theory isolated from practice	 is dead	 and practice which is not illumined by . theory is blind". The theoretical attack on over representation flowing from the reservation rule must be tried out in practice	 as the figures for the last 10 years show; and the justification for more facilities and higher percentage in public employment must be validated by the thesis of social justice. Assertions either way end in a blind alley. That is why we have been at pains to project the constitutional theory and resultant representation of SC and ST reservations under article 16(4). Percentage of reservations made in favour of Scheduled Castes (SC) and Scheduled Tribes (ST).

Classes II and III for the whole of the central services have a range of 3.84% to 7.37% and 9.27% to 12.55% for Scheduled Castes and 0.37% to 1.03% and 1.47% to 3.11% for Scheduled Tribes while their eligibility is of the order of 15% and 7 1/2% respectively. What a grievous beeway after 33 long years may be the acid comment of the victim sector (i.e. the harijans and the girijans). The Central Government has countered the submission of the petitioners	 presented persuasively by Shri Venogopal	 that reservation compounded by the carry forward rule has ended up almost in cent per cent reservation to SC&STs (thus wholly excluding others from job opportunities). The counter affidavit states thus: I do not admit that the Government is giving 100% reservation to the Scheduled Castes and Scheduled Tribes. I submit that normally only 15% and 7 1/2% of the vacancies by means of a roster mechanism are reserved for the Schedule Castes and Scheduled Tribes respectively. However	 in the following cases	 it may look as if 100% of the available vacancies are being given to the Scheduled Castes/Scheduled Tribes. Of course	 based on Rangachari (supra) the State contends that entry even at the promotional points is constitutionally permitted and protected. The grievance that junior harijans steal a march over other senior members of service is exceptional rather than general	 according to the Railway Board	 and	 in any case	 is inevitable where reservation is permissible. Furthermore the Ministry of Railways	 having regard to article 335 had taken special care to give training	 coaching and the like	 to prevent inefficiency and to promote competency of SC&ST members in service. The deponent on behalf of the Union of India has explained the position thus: I submit that the Ministry of Railways	 in 1974 after reviewing the position of intake of Scheduled Castes and Scheduled Tribes in groups of posts filled by promotion in Railway Services	 and on the basis of a recommendation made by the Parliamentary Committee on the Welfare of Scheduled Castes and Scheduled Tribes	 introduced a scheme of training of the Scheduled Castes/Scheduled Tribes employees on the jobs of the posts to which they are to be promoted. According to this scheme	 if	 during selection proceedings	 it is found that the Scheduled Castes/ 229 Scheduled Tribes of requisite standards are not available for being placed on the panel	 the best among them numbering to the extent of reserved vacancies i.e. who secure the highest marks	 are provided with in service training. For this purpose	 such candidates are promoted an ad hoc basis for a period of six months to the grade of the post on the jobs of which they are to receive training. During the said six months ' period	 the administration give them all facilities for improving their knowledge and coming upto the requisite standard	 if necessary by organising special coaching classes. At the end of six months ' period	 a special report is obtained on the working of such candidate which is reviewed by the General Manager or other competent authority. If	 as a result of this review	 they are found to have come upto the requisite standard of fitness to hold the post on regular basis	 they are included in the panel and are promoted to the grade regularly. If	 however	 the said review reveals that such candidates	 even after receiving the training on the jobs to which they are to be promoted regularly	 have not come upto requisite standard of suitability	 such candidates are immediately reverted to the grade from which they were given ad hoc promotion for the purpose of training. A further plea is taken that temporary promotions on ad hoc basis are sometimes given to SC&ST members purely for short duration "for the purpose of imparting them with in service training on the jobs of the post to which they aspire for promotion". This had to be treated as a training period rather than an unconstitutional promotion over the heads of seniors. In short	 the factual submission of massive infiltration of incompetent harijans/girijans into the Railway Service vertically all along the line is refuted by facts and figures. Secondly	 the legal contentions of the petitioners have also been contested by the Union of India (given earlier). In this background	 we may formulate the following points round which arguments have ranged and then deal with some mini submissions and technical objections put forward before us. (1) Does article 16(1) insist on absolute equality or permit realistic and rational classification of unequal classes and treatment of such classes differently ? (2) Do SC&STs stand in a different class from the rest of the Indian community? 230 (3) Are SC&ST castes	 within the scope of article 16(2) ? If so	 does article 16(4) save special provisions in their favour in matters promotion and allied matters ? (4) Do the directives under attack impair administrative efficiency to a degree that it is violative of article 335 ? (5) Do the ten circulars reduce the fundamental right under article 16(1) to a husk or cipherise it altogether ? We must state certain constitutional fundamentals and societal elementals before we make a dialectical study of the basic issues thrown up by these cases. Most of the submissions made by counsel for petitioners cannot survive Rangachari and Thomas (supra) and our task is simplified by abiding by the propositions laid down therein	 because these twin rulings bind us being of benches of five and seven judges. Even though we would	 we could not and even though we could	 we would	 not depart from the holdings in these twin land mark cases which set the gravestone on many of the contentions. What are the constitutional fundamentals bearing on egalite vis a vis backward classes	 especially the SC&STs ? What are the social essentials afflicting the life style of the SCs&STs ? What is economic backwardness as distinct from social injustice and how does the Constitution strike the path of remedial jurisprudence harmonising the demands of both categories? A luminous preface to the constitutional values nullified by social realities is found in Dr. Ambedkar 's address to the Constituent Assembly earlier extracted	 which draws poignant attention to the life of contradictions between the explosive social and economic inequalities and the processes of political democracy. "How long shall we continue to live this life of contradictions ? How long shall we continue to deny equality in our social and economic life?" Was the interrogation before the framers of the Constitution and they wanted to enforce the principle of 'one man	 one value '. This perspective must inform the code of equality contained in articles 14 to 16. Equality being a dynamic concept with flexible import this Court has read into articles 14 to 16 the pragmatic doctrine of classification and equal treatment to all who fall within each class. But care must be taken to see that classification is not pushed to such an extreme point as to make the fundamental right to equality cave in and collapse. (See observations in Triloki Nath Khosa and Ors. vs State of Jammu and Kashmir 231 Ray	 C.J. in Kerala vs Thomas epitomised the position in a few passages: Articles 14	 15 and 16 from part of a string of constitutionally guaranteed rights. These rights supplement each other. Article 16 which ensures to all citizens equality of opportunity in matters relating to employment is an incident of guarantee of equality contained in Article 14. Article 16(1) gives effect to Article 14. Both Articles 14 and 16(1) permit reasonable classification having a nexus to be the object to be achieved. Discrimination is the essence of classification. Classification is	 therefore	 to be founded on substantial differences which distinguish persons grouped together from those left out of the groups and such differential attributes must bear a just and rational relation to the object sought to be achieved. There is no denial of equality of opportunity unless the person who complains of discrimination is equally situated with the person or persons who are alleged to have been favoured. Article 16(1) does not bar a reasonable classification of employees or reasonable tests for their selection. State of Mysore vs V. P. Narasinga Rao. This equality of opportunity need not be confused with absolute equality. Under Article 16(1) equality of opportunity of employment means equality as between members of the same class of employees and not equality between members of separate	 independent class. The rule of parity is the equal treatment of equals in equal circumstances. The rule of differentiation in enacting laws differentiating between different persons or things in different circumstances. The circumstances which govern one set of persons or objects may not necessarily be the same as governing another set of persons or objects so that the question of unequal treatment does not really arise between persons governed by different conditions and different sets of circumstances. A classification in order to be constitutional must rest upon distinctions that are substantial and not merely illusory. The test is whether it has a reasonable basis free from artificiality and arbitrariness embracing all and omitting none naturally falling into that category. 232 The learned Chief Justice relied upon earlier decisions to substantiate this proposition. In Triloki Nath Khosa vs State of J & K(1) this Court had held that the State may make rules guided by realities just as the legislature "is free to recognise degrees of harm and it may confine its restrictions to those classes of cases where the need is deemed to be the clearest." Thus we arrive at the constitutional truism that the State may classify	 based upon substantial differentia	 groups or classes and this process does not necessarily spell violation of articles 14 to 16 Therefore	 in the present case if the SC&STs stand on a substantially different footing they may be classified group wise and treated separately since there is a Great Divide between the SC&STs on the one hand and the rest of the Indian community on the other. This is no matter of speculation or investigation because the Constitution itself has recognised the direst socioeconomic backward status of these species of humanity. We may quote Ray	 C.J. where he observed: The Constitution makes a classification of Scheduled Castes and Scheduled Tribes in numerous provisions and gives a mandate to the State to accord special or favoured treatment to them. Article 46 contains a Directive Principle of State Policy fundamental in the governance of the country enjoining the State to promote with special care educational and economic interests of the Scheduled Castes and Scheduled Tribes and to protect them from any special injustice and exploitation. Article 335 enjoins that the claims of the members the Scheduled Castes and Scheduled Tribes to the services and posts in the Union and the States shall be taken into consideration. Article 338 provides for appointment by the President of a Special Officer for the Scheduled Castes and Scheduled Tribes to investigate all matters relating to the safeguards provided for them under the Constitution. Article 341 enables the President by public notification to specify castes	 races or tribes which shall be deemed to be Scheduled Castes in the States and the Union Territories. Article 342 contains provision for similar notification in respect of Scheduled Tribes. Article 366(24) and (25) defines Scheduled Castes and Scheduled Tribes. The classification by the impugned rule and the order is with a view to securing adequate representa 233 tion to Scheduled Castes and Scheduled Tribes in the services of the State as otherwise they would stagnate in the lowest rung of the State services. Article 335 of the Constitution states that claims of members of the Scheduled Castes and Scheduled Tribes shall be taken into consideration in the making of appointments to the services and posts in connection with affairs of the State consistent with the maintenance of efficiency of administration. I had made similar observations in the same case: The Directive Principles of State Policy	 fundamental in the governance of the country	 enjoin on the State the promotion 'with special care the educational and economic interests of the weaker sections of the people	 and	 in particular	 of the Scheduled Castes and the Scheduled Tribes. and protect them from social injustice '. To neglect this obligation is to play truant with article 46. Undoubtedly	 economic interests of a group as also social justice to it are tied up with its place in the services under the State. Our history	 unlike that of some other countries	 has found a zealous pursuit of government jobs as a mark of share in State power and economic position. Moreover	 the biggest and expanding	 with considerable State undertaking	 employer is Government	 Central and State	 much so appointments in the public services matter increasingly in the prosperity of backward segments. The Scheduled Castes and Scheduled Tribes have earned special mention in article 46 and other weaker section ' in this context means not every 'backward class ' but those dismally depressed categories comparable economically and educationally to Scheduled Castes and Scheduled Tribes. Proceeding on this footing	 the fundamental right of equality of opportunity has to be read as justifying the categorization of SC&STs separately for the purpose of "adequate representation" in the service under the State. The object is constitutionally sanctioned in terms	 as articles 16(4) and 46 specificate. The classification is just and reasonable. We may	 however	 have to test whether the means used to reach the end are reasonable and do not outrun the purposes of the classification. Thus the scope of the case is narrowed down. 234 Of course	 apart from article 16(1)	 article 16(2) expressly forbids discrimination on the ground of caste and here the question arises as to whether the Scheduled Castes and Tribes are castes within the meaning of article 16(2). Even assuming that there is discrimination	 article 16(2) cannot be invoked unless it is predicated that the Scheduled Castes are 'castes '. Terminological similarities are an illusory guide and we cannot go by verbal verisimilitude. It is very doubtful whether the expression caste will apply to Scheduled Castes. At any rate	 Scheduled Tribes are identified by their tribal denomination. A tribe cannot be equated with a caste. As stated earlier	 there are sufficient indications in the Constitution to suggest that the Scheduled Castes are not mere castes. They may be something less or some thing more and the time badge is not the fact that the members belong to a caste but the circumstance that they belong to an indescribably backward human group. Ray	 C.J. in Kerala vs Thomas (supra) made certain observations which have been extracted earlier to make out that "Scheduled Castes and Scheduled Tribes are not a caste within the ordinary meaning of caste". Since a contrary view is possible and has been taken by some judges a verdict need not be rested on the view that SCs are not castes. Even assuming they are	 classification	 if permitted	 will validate the differential rules for promotion. Moreover	 article 16(4) is an exception to article 16(2) also. The constitutional enquiry is whether the harijan/girijan fold is so sharply marked off from the rest of the Indian human family as to justify classification for considerate treatment in the field of public employment ? Let us be sure of the social facts. Mark Twain cynically remarked once: "Get your facts first	 and them you can distort them as much as you please. " By that token	 let us scan the status of the SC&STs	 the result of reservations in habilitating them into State services and the depressment impact on efficiency by supersession of meritorious seniors. It is a fact of our social history and a blot on our cultural heritage that 135 million men and women	 described as SC&STs	 have been suffering as "suppressed classes"	 denied human dignity and languishing as de facto bonded labour. They still are	 in several places	 "worse than the serf and the slave" and "their social standard is lower than the social standard of ordinary human beings" (Ambedkar). Tortured	 violated and even murdered	 the saga of the SC&STs is not only one of economic exploitation but of social ostracisation. Referring to the sorrows of the suppressed shudras (what I 235 prefer to call the panchama proletariat) Swami Vivekananda demanded shudra raj and refuted the incapabilities of the groaning untouchables: "Aye	 Brahmins	 if the Brahmin has more aptitude for learning on the ground of heredity than the Pariah	 spend no more money on the Brahmin 's education but spend all on the Pariah. Give to the weak	 for there all the gift is needed. Our poor people	 these downtrodden masses of India	 therefore	 require to hear and to know what they really are. Aye	 let every man and woman and child	 with out respect of caste or birth	 weakness and strength	 hear and learn that behind the strong and the weak	 behind the high and the low	 behind everyone	 there is that Infinite Soul	 assuring that infinite possibility and the infinite capacity of all to become great and good. Let us proclaim to every soul 'Arise	 awake and stop not till the goal is reached. ' Arise	 awake! To make democracy functional and the republic real the social and economic personality of these backwardmost sections had to be restored. From this angle	 the ancient injustice on the shudras among the shudras has to be liquidated by effective equalising measures. Power	 material power	 is the key to socioeconomic salvation and the State being the nidus of power the framers of the Constitution have made provision for representation of these weaker sections both in the legislature and the executive. More poignant is the fact that all the welfare programmes have been only on paper	 not in practical life. With all the 'pampering ' complained of	 we find that these downtrodden millions remain at the bottom of the socioeconomic scale and totter in the administrative services surviving with difficulty and securing some promotion here or there amidst a hostile milieu. If the concessions	 reservations	 relaxations and other partisan provisions had actually brought into the Services a considerable percentage at least commensurate with their population	 maybe	 the grievance voiced may ring true. But as late as 1971	 a former Minister	 B. section Murthy	 in his book "Depressed and Oppressed (Forever in Agony)" has given a sombre picture of the actual plight of the harijans of India and the figures of employment in Government Services of Scheduled Castes and Tribes as on 1 1 1970 (20 years after the Constitution) furnished by him (p. 74) are tell tale. In Class I services percentage wise these castes which constitute 22.5% of India 's population had 0.40% in Class II	 0.40	 in 236 Class III	 1.47 and in Class IV	 3.41. This was socioeconomic democracy in reverse gear and a callous picture of under representation in administration as if harijans and girijans were still untouchable and unapproachable	 vis a vis Services under the State. Once we realise with John Tyndall that "It is as fatal as it cowardly to blink facts because they are not to our taste"	 the wind is taken out of the sails of the case of the petitioners. For	 in truth and actual life whatever the Railway Board 's orders may say the representation of the SC&STs remains substantially below the sanctioned level although fair representation	 at least in proportion to their population is what is demographically just	 ignoring for the moment the neutralisation of the iniquitions past. We must remember that article 14 speaks of equality before the law and article 16 vouchsafes equality of opportunity. The social dynamics of equality involve the strategy of equalisation in a society of stratification through casteification. One of us did observe : "In a spacious sense	 'equal opportunity ' for members of a hierarchical society makes sense only if a strategy by which the under privileged have environmental facilities for developing their full human potential. This consummation is accomplished only when the utterly depressed groups can claim a fair share in public life and economic activity	 including employment under the State	 or when a classless and casteless society blossoms as a result of positive State action. To help the lagging social segments	 by special care	 is a step towards and not against a larger and stabler equality. . It is a statistically proved social reality in India that the depressed employment position of harijans is the master problem in the battle against generations of retardation	 and 'reservation ' and other solutions have made no significant impact on their employment in public services. In such an unjust situation	 to maintain mechanical equality is to perpetuate actual inequality. A battery of several programmes to fight down this fell backwardness must be tried out by the State." Subha Rao	 J. in Devadasan 's case brought out the need for equalisation to produce stable equality in society by a telling imagery. Although he was in a minority on one point in that case	 that did not detract from the validity or force of the general observations: 237 Article 14 lays down the general rule of equality. Article 16 is an instance of the application of the general rule with special reference to opportunity of appointments under the State. It says that there shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State. If it stood alone	 all the backward communities would go to the wall in a society of uneven basic social structure; the said rule of equality would remain only an utopian conception unless a practical content was given to it. Its strict enforcement brings about the very situation it seek to avoid. To make my point clear	 take the illustration of a horse race one is a first class race horse and the other an ordinary one. Both are made to run from the same starting point. Though theoretically they are given equal opportunity to run the race	 in practice the ordinary horse is not given an equal opportunity to compete with the race horse. Indeed	 that is denied to it. So a handicap may be given either in the nature of extra weight or a start from a longer distance. By doing so	 what would otherwise has been a force of a competition would be made a real one. The same difficulty had confronted the makers of the Constitution at the time it was made. Centuries of calculated oppression and habitual submission reduced a considerable section of our community to a life of serfdom. It would be well nigh impossible to raise their standards if the doctrine of equal opportunity was strictly enforced in their case. They would not have any chance if they were made to enter the open field of competition without Adventitious aids till such time when they could stand on their own legs. A strikingly similar strain of justice thinking has been developed in other jurisdictions in the field of equal protection and benign discrimination by Polyvos G. Polyviou in his book "The Equal Protection of the Laws". It may be meaningful to notice the argument : ". focuses on the concepts of equal treatment and equal opportunity	 professes to construe them realistically	 and declares that '(t) he minority applicant does not have an opportunity "equal" to the white 's because the discriminatory denial of educational	 professional and cultural opportunities for generations past has severely handicapped him in any contest of early intellectual attainment '. As Professor Cox has well put the question	 '(d) we achieve 238 equality by putting each individual on the same starting line today or by giving minority applicants head starts designed to offset the probable consequences of past discrimination and injustice against the group with which the applicant is identified ? The same author deals with 'reverse discrimination ' in school admissions and refers to Prof. Dworkin 's socio jural defense of preferences: Nor should it be forgotten in this connection that	 at least in terms of traditional theory	 rights to equal treatment and to freedom from discrimination	 as normally conceived	 are personal and individual	 and that '(e)qual protection is not achieved through (the) indiscriminate imposition of inequalities for the alleged benefit of groups	 however disadvantaged. Benevolent quotas and reverse discrimination on this view	 fatally offend fundamental notions of individualism inherent in the notion of equality. In answer	 it may be said that to regard the concept of equality simply from this (traditionally) individualistic point of view is to take an unduly restrictive view of its social function and to ignore its allegedly multifaceted character. Or	 to adopt a somewhat different strategy	 one may read the right to equal treatment (both the more general right to equality and the right enshrined in the constitutional guarantee of equal protection) in a particularly abstract way and formulate it in such a manner that it is not necessarily violated by the adoption of benign racial classifications. In this way	 Professor Dworkin distinguishes between two 'different sorts of rights ' which individuals may be said to have. The first is the right to equal treatment	 which is the right to an equal distribution of some opportunity or resource	 and the second is the right to treatment as an equal	 'which is the right	 not to receive the same distribution of some burden or benefit	 but to be treated with the same respect and concern as anyone else '. For Dworkin it is the right to treatment as an equal that is fundamental	 whilst the right to equal treatment is only derivable	 and it is the former that	 as a general matter	 is given 'constitutional standing ' by the Equal Protection Clause. In other words	 white applicants for admission to Law School who may have been turned away because of the reservation of some places for members of disadvantaged minority groups cannot (in a case like the one set out above) successfully complain	 the reason being that they 239 do not have a right to equal treatment in the assignment of places	 but they do have the right to be treated as equals	 that is	 with equal respect	 concern and sympathy	 in the making of decisions as to which admissions standards should be used. More specifically	 this right is viewed by Dworkin as meaning that each candidate for admission has a right that his interests should be looked at 'as fully and sympathetically ' as the interests of any others when decisions are being taken as to which of the many possible criteria for admission to elevate to the status of the pertinent ones. But if this condition is satisfied	 rejected white applicants will fail in their contention that the particular admissions program was unfair and unconstitutional (even if they had been effectively excluded from consideration as a result of the adoption of racial criteria in determining the allocation of some of the available places). The simple question Dworkin would ask in these cases is whether the particular admissions program serves a proper policy that respects the right of all members of the community to be treated as equals	 but not otherwise. No debate is needed to uphold reservation in promotions as such. Not only has Rangachari sustained it in regard to selection posts	 Thomas 's case decided by a Bench of seven Judges	 has expressly approved Rangachari. The only question bearing on reservation vis a vis promotion is as to whether it is unconstitutional if it is extended to non selection posts while it is constitutional in regard to selection posts. Anyway	 Annexure F	 one of the circulars sought to be quashed by the petitioners relates only to selection posts and has been expressly upheld in Rangachari 's case. The quantum of reservation is not excessive; the field of eligibility is not too unreasonable	 the operation of the reservation is limited to selection posts and no relaxation of qualifications is written into the circular except that candidates of the SC&ST communities "should be judged in a sympathetic manner". Moreover	 administrative efficiency is secure because there is a direction "to give such staff additional training and coaching	 to bring them up to the standard of others". The rejection of the invalidatory contention of the petitioners is inevitable. Annexure H is bad for unconstitutionality according to the petitioners for many reasons. For one thing	 an SC/ST employee gets one grading higher than otherwise assignable to him on the record of his service. So much so	 if he is 'good ' he will be categorised as 'very 240 good '. This fiction or fraud in grading is said to be a vice rendering the promotional prospects unreasonable. We do not agree. Superficially viewed	 this clumsy process of reclassifying ability may strike one as disingenuous. Of course	 this concession is confined to only 25% of the total number of vacancies in a particular grade or post filled in a year. So there is no rampant vice of every harijan or girijan jumping over the heads of others. More importantly	 we think this is only an administrative device of showing a concession or furtherance of prospects of selection. Even as under article 15(4) and article 16(4) lesser marks are prescribed as sufficient for SC&STs or extra marks are added to give them an advantage the re grading is one more method of boosting the chances of selection of these depressed classes. There is nothing shady about it. If there is advancement of prospects of SC&ST by addition of marks or prescribing lesser minimum marks or by relaxing other qualifications	 I see no particular outrage in re categorisation which is but a different mode of conferring an advantage for the plain and understandable reason that SC&STs do need some extra help. It is important to note that the prescribed minimum qualifications and standards of fitness are continued even for SC&STs under Annexure H. The other vice pointed out against Annexure H is that the qualifying marks in respect of SC&ST candidates is somewhat less than is applicable to candidates of unreserved groups. There is no merit in this objection and no good ground exists which militates against the constitutionality of Annexure H. Annexure I is also unexceptionable since all that it does: is to readjust the proportion of reservation in conformity with the latest Census. Posts for which recruitment	 realistically speaking	 takes place on a regional basis are subjected to reservation taking into account the percentage of SC&ST population in the concerned State. This is also reasonable. Likewise	 the carry forward rule being raised from 2 years to 3 years also cannot be struck down. It must be realised that law is not an abstraction but an actual prescription in action. So what we have to be more careful about is to scrutinise whether the carry forward rule by being increased to 3 years is going to confer a monopoly upon the SC&ST candidates and deprive others of their opportunity for appointment. From the percentage furnished by the Railway Board we find that even if we carry forward vacancies for any number of years there is no prospect	 within the reasonable future	 of sufficient number of SC & ST candidates turning up to fill them. There is a provision that if sufficient number of candidates from the SC & ST are not found	 applicants from the unreserved communities will be given the appointment provisionally. After 3 years those vacancies cease to be reserved. Going by the actuals it is clear that no serious infraction of 241 any individual 's fundamental right under article 16(1) takes place and no monopoly is conceivably conferred on SC&ST candidates	 they are not available in sufficient numbers to reach anywhere near the percentage reserved. Even going by the majority	 Devadasan 's case ( ' ) lays down the proposition that under article 16(4) "reservation of a reasonable percentage B of posts for members of the Scheduled Castes and Tribes is within the competence of the State. What the percentage ought to be must necessarily depend upon the circumstances obtaining from time to time. " Madholkar	 J. speaking for the majority has struck down only one restriction. "In order to effectuate the guarantee each year of recruitment will have to be by itself and the representation for backward communities should not be so excessive as to create a monopoly or to disturb unduly the legitimate claims of other communities. " (emphasis added). Unlimited reservation of appointments may be impermissible because it renders article 16(1) nugatory. At the same time	 article 16(4)	 calculated to promote social justice and expressive of the deep concern of the Constitution for the limping bracket of Indians	 must be given full play. That is why the only restraint imposed by Mudholkar	 J. is that an exercise of power under article 16(4) "does not mean that the provision made by the State should have the effect of virtually obliterating the rest of the Article	 particularly clauses (1) and (2) thereof."( ') By the three year 'carry forward ' rule one is unable to see how	 in practice	 the total vacancies will be gobbled up by the harijan/girijan groups "virtually obliterating" article 16(1). The court has made it very clear that the problem of giving adequate representation to backward classes under article 16(4) is a matter for the Government to consider	 bearing in mind the need for a reasonable balance between the rival claims as pointed out in Balaji 's case.(2) It is true that in Balaji 's case and Devadasans case(l) 'the carry forward ' rule for backward classes for exceeded 50% and was struck down. We must remember that the percentage of reservation for backward classes including SC&ST was rather high in both the cases. In Devadasan 's case the court went into the actuals	 not into the hypothetical. This is most important. The Court actually verified the degree of deprivation of the 'equal opportunity ' right and discovered: (3 ) In the case before us 45 vacancies have actually been filled out of which 29 have gone to members of the Scheduled (1) ; at 695. (2) [1963] Supp. 1 SCR 439. (3) Ibid at 693 94. 242 Castes and Tribes on the basis of reservation permitted by the carry forward rule. This comes to about 64.4% of reservation. Such being the result of the operation of the carry for ward rule we must	 on the basis of the decision in Balaji 's case hold that the rule is bad. (emphasis added) What is striking is that the Court did not take an academic view or make a notional evaluation but checked up to satisfy itself about the seriousness of the infraction of the right. On that footing	 the petitioners have not demonstrated that in any particular year	 virtually and in actual terms of promotion	 there has been a substantial excess over 50% in favour of the SC&ST promotees. Mathematical calculations	 departing from realities of the case	 may startle us without justification	 the apprehension being misplaced. All that we need say is that the Railway Board shall take care to issue instructions to see that in no year shall SC&ST candidates be actually appointed to substantially more than 50% of the promotional posts. Some excess will not affect as mathematical precision is different in human affairs	 but substantial excess will void the selection. Subject to this rider or condition that the 'carry forward ' rule shall not result	 in any given year	 in the selection or appointments of SC&ST candidates considerably in excess of 50%	 we uphold Annexure I. Heated arguments about the hurt caused by Annexure 'J ' have been addressed to us. It deals with the 40 point roster and the posts allotted to the SC&ST allottees. Once the fundamental premises are accepted there is nothing unreasonable or wrong in Annexures 1 and 2 to Annexure J. It is significant that with a view to prevent total exclusion of others there is a provision that if there are only two vacancies in a given year	 in more than one may be treated as reserved and if there is only one vacancy	 it should be treated as unreserved. Implementation of reservations necessarily involves practical steps like evolving a roster system. Once the parameters of reservation are within the framework of the fundamental rights	 minute scrutiny of every administrative measure and hunting for unconstitutionality is not permissible. Far more serious is the criticism of Annexure 'K ' on the basis of which reservations were introduced even to promotion posts filled by the 'seniority cum suitability ' rule. Some other relaxations and con cessions also are granted under it to SC/ST candidates. But the maximum mayhem inflicted by Annexure K is in the extension of the operation of promotional reservation to non selection posts. It was urged that Rangachari (supra) did not cover non selection posts and	 there 243 fore	 could not be an authority to sustain its validity. There is no force in this submission. The sting of the argument against reservation is that it promotes inefficiency in administration by choosing sub standards candidates in preference to those with better mettle. Competitive skill is more relevant in higher posts	 especially those where selection is made by competitive examinations. Lesser classes of posts	 where promotion is secured mechanically by virtue of seniority except where the candidate is unfit	 do not require a high degree of skill as in the case of selection posts. (See 1968 1 SCR p. 721 at 734). It is obvious that as between selection and non selection posts the role of merit is functionally more ` relevant in the former than in the latter. And if in Rangachari reservation has been held valid in the case of selection posts	 such reservation in non selection posts is an afortiori case. If	 in selecting top officers you may reserve posts for SC/ST with lesser merit	 how can you rationally argue that for the posts of peons or lower division clerks reservation will spell calamity ? The part that efficiency plays is far more in the case of higher posts than in the appointments to the lower posts. On this approach Annexure K is beyond reproach. One may easily sympathise with holders of non selection posts. They are many in number in the lower stations of life. They are economically backward and burdened with the drudgery of life. That is why there is a ballyhoo raised by a larger number of people when some categories in far more distressing social situations enter the arena with preferential treatment. Looking at the problem from the point of view of law and logic and the constitutional justification under article 16(4) for reservation in favour of the panchama proletariat there is nothing to strike down in Annexure K. As between the socially	 even economically depressed and the economically backward	 the Constitution has emphatically cast its preference for the former. Who are we	 as Judges to question the wisdom of provisions made by Government within the parameters of article 16(4)? The answer is obvious that the writ of the court cannot quash what is not contrary to the Constitution however tearful the consequences for those who may be adversely affected. The progressive trend must	 of course	 be to classify on the have not basis but the SC/ST	 category is	 generally speaking	 not only deplorably poor but also humiliatingly pariah in their lot. Maybe	 some of the forward lines of the backward classes have the best of both the words and their electoral muscle qua caste scares away even radical parties from talking secularism to them. We are not concerned with that II dubious brand. In the long run	 the recipe for backwardness is not creating a vested interest in backward castes but liquidation of handi 244 caps	 social economic	 by constructive projects. All this is in another street and we need not walk that way now. Trite arguments about efficiency and inefficiency are a trifle phoney because	 after all	 at the higher levels the harijan/girijan appointees are a microscopic percentage and even in the case of Classes III and II posts they are negligible. The preponderant majority coming from the well reserved communities are presumably efficient and the dilution of efficiency caused by the minimal induction of a small percentage of 'reserved ' candidates cannot affect the over all administrative efficiency significantly. Indeed	 it will be gross exaggeration to visualise a collapse of the Administration because 5 to 10% of the total number of officials in the various classes happen to be sub standard. Moreover	 care has been taken to give in service training and coaching to correct the deficiency. It is fashionable to say and there is	 perhaps	 some truth in it that from generation to generation there is a deterioration in efficiency in all walks of life from politics to pedagogy to officialdom and other professions. Nevertheless	 the world has been going forward and only parties whose personal interest is affected forecast a doom on account of progressive deficiency in efficiency. We are not impressed with the misfortune predicted about governmental personnel being manned by morons merely because a sprinkling of harijans/girijans happen to find their way into the Services. Their apathy and backwardness are such that in spite of these favourable provisions	 the unfortunates have neither the awareness nor qualified members to take their rightful place in the Administration of the country. The malady of modern India lies elsewhere	 and the merit mongers are greater risks in many respects than the naive tribals and the slightly better off low castes. Nor does the specious plea that because a few harijans are better off	 therefore	 the bulk at the bottom deserves no jack up provisions merit scrutiny. A swallow does not make a summer. Maybe	 the State may	 when social conditions warrant	 justifiably restrict harijan benefits to the harijans among the harijans and forbid the higher harijans from robbing the lowlier brethren We have adverted to Annexure M earlier in this judgment which shows the determination of Government to impart in service training to those SC&ST candidates who are found to be below par. Even temporary promotions on an ad hoc basis are limited to six months only to give training and experience than the spoil permanently the efficiency of the system. The Annexure has come under attack because the reservation quota has been raised thereby from 50 to 66 2/3%. We have earlier dis 245 cussed this aspect and pointed out that what is important is not so much the figures mentioned on paper but the facts and circumstances in real life. We have also entered a caveat that in any particular year there shall not	 as a fact	 be a substantial increase upon 50% of induction of 'reserved ' candidates. It is true that Shri Venugopal	 counsel for some of the petitioners tried to demonstrate that on account of reservation percentages coupled with the carry forward rule it is perfectly within the realm of possibility that in some years a monopoly may be conferred on the SC&ST candidates for certain categories or classes of posts. The mystic "maybe" do not scare us. The actual "must be" will alert us. The Constitution deals with social realities	 not speculative possibilities. I have limited the physical operation of reservation in any particular year in such a manner that there will be a real opportunity for the exercise of the right under article 16(1) for every candidate of the unreserved communities. Certain minor attacks such as that a candidate of the SC&ST communities who has failed may still be tried if other successful candidates from those communities are not forthcoming. This may seem strange disbelief in examinations as measure of merit. But to read stray provisions in isolation may be unfair to the scheme. Look at the desperate State in which Government is trying to give fair representation to harijans/girijans in Administration. These miserables suppressed by centuries of trampling are still slumbering despite inducements to awaken. It is a genetic calumny and unscientific assertion to castigate the SC&ST communities as possessed of less intellectual potential what with Valmiki and Vyasa to Baba Sahib Ambedkar. The darkening and be numbing environment of ages in which shudras and panchamas have suffered their mental powers to be chained accounts for their seeming	 retardation. Once brighter atmosphere and better opportunity enliven their talent their contribution to the Indian treasury will raise the human resources and democratic status of Bharat. A democracy of talent is an inarticulate major premise of our culture. The fundamental question arises as to what is "merit" and "suitability". Elitists whose sympathies with the masses have dried up are	 from the standards of the Indian people	 least suitable to run Government and least meritorious to handle state business	 if we envision a Service State in which the millions are the consumers. A sensitized heart and a vibrant head	 tuned to the tears of the people	 will speedily quicken the developmental needs of the country	 including its rural stretches and slum squalour. Sincere dedication and intellectual integrity these are some of the major components of "merit" and "suitability" not degrees from Oxford or Cambridge	 Harvard or Stanford or simian	 though Indian	 246 institutions. Unfortunately	 the very orientation of our selection process is distorted and those like the candidates from the SC&ST who	 from their birth	 have had a traumatic understanding of the conditions of agrestic India have	 in one sense	 more capability than those who have lived under affluent circumstances and are calIous to the human lot of the sorrowing masses. Moreover	 our examination system makes memory the master of 'merit ' and banishes creativity into exile. We need not enter these areas where a fundamental transformation and a radical re orientation even in the assessment of the qualities needed by the personnel in the Administration and the socialist values to be possessed by the echelons in office is a consummation devoutly to be wished. This may have to be subjected to a national debate. The colonial hangover still clings to our selection processes with superstitious tenacity and narrower concepts of efficiency and merit are readily evolved to push out Gandhis and J.Ps	 Ambedkars and Nehrus	 to mention but a few who knew the heart beats of the people. I diva gate and make these observations only to debunk the exaggerated argument about harijans and girijans being sub standard. We may put aside this angle of vision and approach the problem traditionally because every new idea has resistance to encounter before acceptance	 every original thought has been branded a hearsay. Be that as it may	 the constitutional merits of the various Board Circulars now discussed do not warrant their judicial 'execution ' subject to certain cautionary limitations already indicated. The argument that there are rich and influential harijans who rob all the privileges leaving the serf level sufferers as suppressed as ever. The Administration may well innovate and classify to weed out the creamy layer of SC&ST but the court cannot force the State in that behalf. For a comparative thought we may glance at Polyviou 's 'The Equal protection of the laws ': ( ') "A third argument traditionally employed against the use of preferential discrimination is that affirmative measures of the kind discussed here may significantly curtail efficiency. It does indeed stand to reason that the immediate result of benignity in admission and selection process will almost certainly be the selection of those who are not as competent or as able as some of those left out. 'Special admission programmes	 almost by definition	 operate to in sure that students are placed in schools for which they are (1) The equal protection of the laws by G. Polyviou p. 360. 247 not qualified ! The same objection applies with equal	 if not more	 force to the area of employment and elsewhere. One possible answer is that the importance of efficiency must be compared with and ultimately set against the significance of integration or the prevention of discrimination	 and that integration and the rectification of socially harmful deprivation are the more pressing needs. Or one can fall back on the very different arguments that traditional admission processes are unfair because these are geared to the usual type of applicant and that preferential treatment after all only seeks to counteract such inherent bias. There is a human problem behind these writ petitions which we clearly appreciate. Most of the Classes II	 III and IV employees are economically backward and struggle for survival what with price spirals and other tribulations. They hope	 after years of yeomen service	 to get some promotion and augment their poor resources in the afternoon of their life. Then they find another class	 with which the Constitution shows ultra sympathy	 elbowing them out	 not on a massive scale	 but minimally. Even this marginal push hurts these species living at subsistence level and so they scream. The economically backward and the socio economically backward truly belong to the 'have not ' camp and must jointly act to bring about a transformation of the economic order by putting sufficient pressure and make article 38 a living reality. Estrangement between the two categories weakens the militancy of a joint operation to inject social justice in the current economic order. The truth is that the employment market is distressingly a musical chair business and when starvation faces men their sympathy for their far weaker brethren vanishes. The true solution for the country 's problems	 as reflected in these writ petitions	 is in developmental expansion involving the millions	 rather than denial to the weakest sector of Indian life the morsel to which it is justly entitled. Even Administration will do well to remember that Indian despair	 after infinite patience	 may augur danger unless 'the sorry scheme of things entire ' is remoulded nearer to article 38. Even these observations are made only to emphasise that the legal content of the contentions put forward by the petitioners is less than presentable although their economic grievance may be agonisingly genuine. The Court has its limitations unlike the Administration and can give justice only under the Constitution and not over it. The human pressure behind these writ petitions is the chronic drought of employment opportunities despite talent enough to make 248 deserts bloom. So long as this scarcity persists and power goes with office	 the jaundiced politics of snatching the jobs going	 initially or at promotion level	 by hook or crook	 is the only 'development ' that takes place	 whatever the National Plans proclaim. The vast human potential of the harijans and girijans	 on fifth of the Indian people	 goes to thistles and every communal effort to twist the politics of power for promoting chances of getting jobs becomes inevitable caste being a deeprooted pathology in our country. Thus jobbery	 politics	 casteism and elections make an unholy	 though invisible	 alliance against national development which alone can liberate Indians from social and economic privation. If democracy itself thus plays into the hands of hostile forces	 the jurisprudence of keeping the backward as backward and perpetuation of discrimination as a vested caste right may prevail as a rule of life. The remedy of 'reservations ' to correct inherited imbalances must not be an overkill. Backward classes	 outside the Scheduled Castes and Tribes	 cannot bypass article 16(2) save where very substantial cultural and economic disparity stares at society. The dubious obsession with 'backwardness ' and the politicking with castes labelled backward classes may	 on an appropriate occasion	 demand judicial examination. The politics of power cannot sabotage the principles of one man	 one value. No sociological explanation for the flood of ruinous writ petitions regarding service conditions can be found except on this basis. Behind the writ petitions we deal with now is caste clamour to keep all the jobs safe from being 'robbed ' by 'reserved ' communities. It is forward caste versus backward caste	 wearing the casteless caste marks! And the political process is likewise caste polluted Gunnar Myrdal writes in his Asian Drama: ( ' ) The type of appeal that can be made by politicians has also changed greatly since the liberation movement. They can no longer put the blame for poverty and stagnation on colonial masters	 but must explain why there is not great progress now that India is independent Thus a key to the understanding of the power of the political bosses is the inherited social stratification of India and	 above all	 its caste system. At election times the caste groups function as political vote banks whereby the ballots of their members are joined to the candidate with a party label. For this reason alone the local political bosses have a vested interest in preserving the social and economic status quo and exploiting it as a matrix for political action. (1) Gunnar Myrdal	 Asian Drama	 Vol. I	 pp. 249 M. N. Srinivas	 the noted sociologist is more than right (1) A One cannot help wondering whether the drive to political maturity is	 after all	 a good thing in a country which has still not had a proper social revolution. It may well result in premature old age. We need now	 not stagnation wearing the mask of stability and scrambling acrimoniously over the same shrunken cake	 but progress by the constructive process of explosive rural development and exploitation of the untapped human potential of the Scheduled Castes and Scheduled Tribes. Sterile 'reservations ' will not help us go ahead unless	 alongside of it	 we have heroic national involvement of the masses in actual action	 not paper logged plan exercises. In the last analysis	 privation can be banished only by production	 discontent by distributive justice and litigation by socially relevant Justice. The writ petitions are	 regrettably	 negative	 although the driving force of penury deserves sympathy. This	 perhaps	 is a materialist interpretation of 'service litigation ' and a trim foot note to these writ petitions. D Before I conclude	 I must strike a futuristic note. Excellence and equality may cooperating fruitfully and need not compete destructively. Ultimately harijan/girijan militancy must find fulfillment in effective main streaming and creative contribution. While they have miles to go	 they have promises to keep. The poignant words of the Reverend Jesse Jackson come to my mind (1) "I don 't see how	 we can survive as a people if we don 't have a great push for excellence now. A lot of what we 've done in the past will be in vain if we don 't. We can make one of the most valid contributions to Western civilization	 even more of a contribution than slavery. Because slavery was our great contribution against our will. Now it 's time for us to make a great contribution as an act of will. " Given the opportunity and the environment	 the Indian dalits can make India great and give up crutches. The writ petitions as well as the Special Leave Petitions cannot but be dismissed. PATHAK	 J. My brothers Krishna Iyer and Chinnappa Reddy are agreed that the writ petitions should be dismissed. They have held against the petitioners on the several contentions raised in the (1) M. N. Srinivas	 "Changing Attitudes in India Today" Yogana	 October I 1961	 p. 26. 250 case. With respect	 I find myself unable to agree with all that they have said. I intend to confine myself here to certain aspects of the case which appear to possess a fundamental importance. Three provisions of the Constitution relate to reservations for Scheduled Castes and Scheduled Tribes. They are article 46	 article 16(4) and article 335. The three form a single frame of reference. article 46	 a Directive Principle of State Policy	 proclaims the principle that the State shall promote with special care the educational and economic interests of the weaker sections of the people	 and	 in particular	 of the Scheduled Castes and the Scheduled Tribes	 and shall protect them from social injustice and all forms of exploitation. One of the modes in which the economic interests of the Scheduled Castes and Scheduled Tribes can be promoted is the reservation of appointments or posts in their favour in services under the State where they are not adequately represented. article 16(4) declares that when the State intends to make such provision nothing in article 16 shall prevent it from doing so. The equality of opportunity guaranteed to all citizens in matters relating to employment or appointment to any office under the State will not restrain the State from making such reservation. It is now well accepted that the "equality provisions of Part III of the Constitution constitute a single code	 illustrating the multi faceted character of the central concept of equality. article 16(4) also is one facet. It enables a backward class of citizens	 by the process of reservation in Government service	 to move along the road to ultimate equality with the more advanced classes. It is part of the process of equalization. Then follows article 335. It provides that the claims of the members of the Scheduled Castes and Scheduled Tribes shall be taken into consideration in the making of appointments to services and posts in connection with the affairs of the Union or a State	 but and this is imperative such consideration must be consistent with the maintenance of efficiency of administration. The paramount need is to maintain the efficiency of administration. That is dictated by the common good. It embraces the need of all	 the national good	 and not of a mere section of the people. To its primacy all else is subordinate. Therefore	 whatever is done in considering the claims of the Scheduled Castes and Scheduled Tribes must be consistent with that supreme need	 the maintenance of efficiency of administration. article 335	 it must be clearly stated	 does not contain a positive principle	 the advancement of Scheduled Castes and Scheduled Tribes	 and a negative principle	 the maintenance of efficiency of administration. This analysis of the article does not 251 truly comprehend its contents. It contains a single principle	 the A advancement of Scheduled Castes and Scheduled Tribes	 but through modes and avenues which must not detract from the maintenance of an efficient administration. That limitation is imposed as a clear and positive condition. A generally acknowledged and long established principle for securing an efficient administration is throwing open the doors to general recruitment	 either directly or by promotion	 where the governing criterion is excellence and the emphasis is solely on quality. I he net of selection is spread far and wide	 and the competitive best are collected	 regardless of religion	 race	 caste	 sex	 descent	 place of birth or residence. However	 a quota of the posts may be reserved in favour of a backward class of citizens	 but the interests of an efficient administration require that at least half the total number of posts be kept open to attract the best of the nation`s talent and not more than half be made the sum of reserved quotas. If it was otherwise	 an excess of reserved quotaas would convert the State service into a collective membership predominantly of backward classes. This	 it is evident	 will be inconsistent with the all important goal of maintaining the efficiency of administration. In considering the proportion of reserved quotas in the context of college admissions	 this ( 'court laid down in M. R. Balaji vs State of Mysore( ') that broadly a special provision providing for reservation should be less than 50%	 .and how much less than 50% would depend upon the relevant prevailing circumstances in each case. And	 in this connection	 Gajendragadkar	 J. (as he then was) speaking for the Court	 observed: " . when the State makes a special provision for the advancement of the weaker sections of society specified in article 15(4)	 it has to approach its task objectively and in a rational manner. Undoubtedly	 it has to take reasonable and even generous steps to help the advancement of weaker elements; the extent of the problem must be weighed	 the requirements of the community at large must be borne in mind and a formula must be evolved which would strike a reasonable balance between the several relevant considerations." (Emphasis supplied) The Court struck down the reservation of 68% as constitutionally Invalid. (1) [1963] Supp. 1 S.C.R. 439. 252 The principle that reserved quotas should not together exceed 50% of the vacancies available in a year was affirmed by this Court	 by a majority of four learned judges to one	 in T. Devadasan vs Union of India	( ') as the reason for striking down a "carry forward" rule which	 for promotions in the Central Secretariat Service	 permitted a carry forward for two successive years of the annual reserved quota. It was found in that case that observance of the rule had resulted in 65%	 of the vacancies of the year being filled by reserved quotas	 current and carried forward. The "carry forward" rule was held constitutionally invalid on the basis that for the purpose of article 16(1) each year of recruitment had to be considered as a distinct unit for applying the 50% rule. Mudholkar	 J.	 on behalf of the majority	 said: "We would like to emphasize that the guarantee contained in article 16(1) is for ensuring equality of opportunity for all citizens relating to employment	 and to appointments to any office under the State. This means that on every occasion for recruitment the State should see that all citizens are treated equally. The guarantee is to each individual citizen and	 therefore	 every citizen who is seeking employment or appointment to an office under the State is entitled to be afforded an opportunity for seeking such employment or appointment whenever it is intended to be filled. In order to effectuate the guarantee each year of recruitment will have to be considered by itself and the reservation for backward communities should not be so excessive as to create a monopoly or to disturb unduly the legitimate claims of other communities. " It seems to me that apart from the impact that an excessive reservation in a particular year is bound to have on the general community of citizens	 there is the further far reaching significance this assumes in the context of article 335. The maintenance of efficiency of administration is bound to be adversely affected if general candidates of high merit are correspondingly excluded from recruitment because the large bulk of the vacancies	 numbering anything over 50%	 is allotted to the reserved quota. In view of a maximum age limit invariably prescribed	 some of such meritorious candidates may be loss to the service altogether. Viewed in that light	 a maximum of 50% for reserved quotas in their totality is a rule which appears fair and reasonable	 just and equitable	 and violation of which would contravene Art 335. (1) ; 253 It has been urged by the respondents that Devadasn (supra) is A no longer good law in view of the 7 Judge decision in State of Kerala v N. M. Thomas( '). It does appear from some of the individual Judgments delivered in the latter case that although Devadas (supra) has not been expressly overruled by a majority of the Bench there are observations by the majority of Judges which throw doubt on the validity of the principle enunciated by it and ultimately the Court has upheld the promotion of 34 Scheduled Caste and Scheduled Tribe candidates among the total promotion of 51 candidates. It would seem then that there is an apparent conflict between Devadas (supra) and N. M. Thomas (supra). The validity of Rule 13AA of the Kerala State and Subordinate Service Rules	 1958 was questioned in N. M. Thomas (supra). That Rule permitted the exemption of Scheduled Caste and Scheduled Tribe members from passing the promotion tests for a specified period. That more than 50% of the promotions went to the Scheduled Caste and Scheduled Tribe candidates was a consequence of the operation of Rule 13AA. It is doubtful whether the petitioners ' challenge to the "carry forward" rule can avoid what has been said in N. M. Thomas (supra) and	 therefore	 a conclusion in their favour does not seem possible in this case. As the position is not clear	 and in any event as my learned brothers have taken a definite view in favour of the "carry forward" rule	 I have confined myself to expressing these observations. The petitioners have challenged other provisions prescribed in favour of members of the Scheduled Castes and Scheduled Tribes and have attempted to support their submissions by reference to data purporting to prove that those measures have resulted in reverse discrimination and are also inconsistent with the maintenance of efficiency of administration. We have been taken through charts and statistics among other documentary material but the material placed before us does not clearly and definitely establish what it seeks to prove. In the circumstances	 it is not possible to record a finding in favour of the petitioners on those points. G Accordingly	 the writ petitions are dismissed but without any order as to costs. CHINNAPPA REDDY J. In the name of Equality (of opportunity)	 we are asked to deny Equality (of opportunity)	 in these Writ Petitions. That we cannot do and that we will not do. If we do that we will be subverting the spirit and the sense of the Constitution. The (1) ; 254 petitioners claim that their Fundamental Right to Equality of Opportunity in the matter of public employment	 guaranteed by article 16(1) of the Constitution has been flouted by a series of orders and circulars issued by the Railway Board reserving posts at several levels and making various concessions in favour of members of the Scheduled Castes and the Scheduled Tribes. This has been done	 it is claimed	 at the cost of efficiency	 though forbidden by article 335 of the Constitution. The plain answer of the respondents is that everyone of the orders and circulars has the backing of article 16(1)	 16(4) and other special provisions of the Constitution and that the alarm of inefficiency is nothing but a bogey. My brother Krishna Iyer	 J. has considered the questions raised in his own characteristic	 scintillating way and in some depth. Though respect for my brother would ordinarily prevent me from venturing to write a separate opinion	 specially when I agree whole heatedly with his conclusions and the	 route traversed by him	 I propose to make	 in this case	 certain general observations because I expect the same questions to be raised repeatedly in different situations and in different forms and it is just as well that I project my own prosaic and pedestrian point of view	 without going into the detail or depth already explored by my brother. The class of people known compendiously as 'the Scheduled Castes '	 recognized and described as such in the Constitution of India have been treated as 'casteless ' outcastes and untouchables and have been oppressed and subjected to every manner of depravation and discrimination for centuries upon centuries by a unique system of social and economic segregation	 a system of "graded inequality" (Dr. B.R. Ambedkar)	 of "gradation and degradation" (Dr. C.R. Reddy) and of "gigantic cold blooded repression" ( Rabindranath Tagore). And for centuries they were even prevented from protesting their plight. Nor was any attempt made by the superior and elitist classes to know anything about them. All that a Scheduled Caste parent could do was to lament: "Hush	 my child; don 't cry	 my treasure; Weeping is in vain	 For the enemy will never Understand our pain. For the ocean has its limits Prisons have their walls around But our suffering and our torment have no limit and no bound. " Then	 in 1950	 came the Constitution rousing expectations	 raising hopes	 making promises and generally heralding a new	 a bitter and 255 a more decent life for the underprivileged and the oppressed people of India. While the preamble to the Constitution proclaims the resolution of the people to constitute India into a Sovereign (also. 'Socialist	 Secular '	 Since the 42nd Amendment) Democratic Republic and to secure to all its citizens	 "Justice	 Social	 economic and political" and "Equality of Status and opportunity" and to promote 'Fraternity	 assuring the dignity of the individual"	 while the Right to Equality before the Law (article 14) and Equality of Opportunity n the matter of public employment (article 16) are guaranteed as Fundamental Rights and while the State is enjoyed by the Directive Principles of State Policy to promote the welfare of the p people by securing a social order in which justice	 social	 economic and political shall inform all the institutions of the national life article 38(1)	 to endeavour to eliminate inequalities in status	 facilities and opportunities article 38 (2)	 and	 to direct its policy towards securing that the ownership and control of the material resources of the community are so distributed as best to subserve the common good article 39(b) and that the operation of the economic system does not result in the concentration of wealth and means of production to the common detriment article 39(c)	 pursuant to the very preamble and the provisions of the Constitution	 special provisions have been made. in particular	 for the protection and advancement of the Scheduled Castes and the Scheduled Tribes in recognition of their existing	 low social and economic status and the consequent inability and failure on their part to avail themselves of any opportunity for self advancement. It is recognized that the failure of the State to create a climatic situation and provide the necessary impetus for the increasing participation of the members of the Scheduled Castes and the Scheduled Tribes in the public services would tentamount to a denial to them of equal opportunity in the matter of public employment. article 335 which is included in part XVI of the Constitution dealing with 'special provisions relating to certain classes ' expressly provides: "The claims of the members of the Scheduled Castes and the Scheduled Tribes shall be taken into consideration	 consistently with the maintenance of efficiency of administration in the making of appointments to services and posts in connection with the affairs to the Union or of a State. " article 46	 one of the Directive Principles of State Policy	 enjoins: "The State shall promote with special care the educational and economic interest of the weaker sections of the 256 people	 and	 in particular	 of the Scheduled Castes and the Scheduled Tribes	 and shall protect them from social in justice and all forms of exploitation. " i article 16 (1) and 16 (4) which guarantee equality of opportunity in matters of public employment read as follows: "16 (1) There shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State." "16 (4) Nothing in this article shall prevent the State from making any provision for the reservation of appointments or posts in favour of any backward class of citizens which	 in the opinion of the State is not adequately represent in the services under the State " article 16 (2) which bars discrimination on certain rounds is as follows: "16 (2) No citizen shall	 on grounds only of religion	 race	 caste	 sex	 descent	 place of birth	 residence or any of them	 be ineligible for	 or discriminated against in respect of	 any employment or office under the State. " Now	 it has been said	 very rightly	 a Constitutional instrument is sui generis and	 obviously and necessarily	 its interpretation cannot always run on the same lines as the interpretation of statutes made in exercise of the powers conferred by it. A constitution	 like ours	 born of an anti imperialist struggle	 influenced by Constitutional instruments	 events and r evolutions elsewhere	 in search of a better world and wedded to the idea of justice	 economic	 social and political	 to all	 must receive a generous interpretation so as to give all its citizens the full measure of justice so proclaimed instead of 'the austerity of tabulated legalism '(1). And so	 when the Constitutional instrument to be expounded is a constitution like the Indian Constitution	 the expositors are to concern themselves not with words and mere words only	 but	 as much	 with the philosophy or what we may call 'the spirit and the sense ' of the Constitution. Here we do not have to venture upon a voyage of discovery to find the spirit and the sense of the Constitution; we do not have to look to any extraneous sources for inspiration and guidance; they may be sought and found in the Preamble to the Constitution	 in the Directive Principles of State Policy	 and other such provisions. See Minister of Home Affairs : ; 257 Because Fundamental Rights are justiciable and Directive Principles are not	 it was assumed	 in the beginning	 that Fundamental Rights held a superior position under the Constitution than the Directive Principles	 and that the latter were only of secondary importance as compared with the Fundamental Rights. That way of thinking is of the past and has become obsolete. It is now universally recognised that the difference between the Fundamental Rights and Directive Principles lies in this that Fundamental Rights are primarily aimed at assuring political freedom to the citizens by protecting them against excessive State action while the Directive Principles are aimed at securing social and economic freedoms by appropriate	 State action. The Fundamental Rights are intended to foster the ideal of a political democracy and to prevent the establishment of authoritarian rule but they arc of no value unless they can be enforced by resort to Courts. So they are made justiciable. But	 it is also evident that notwithstanding their great importance	 the Directive Principles cannot in the very nature of things be enforced in a Court of law. It is unimaginable that any Court can compel a legislature to make a law If the Court can compel Parliament to make laws then Parliamentary democracy would soon be reduced to an oligarchy of Judges. It is in that sense that the Constitution says that the Directive Principles shall not be enforceable by Courts. It does not mean that Directive Principles are less important than Fundamental Rights or that they are not binding on the various organs of the State. article 37 of the Constitution emphatically states that Directive Principles are 'nevertheless Fundamental in the governance of the country and it shall be the duty of the State to apply these principles in making laws. It follows that it becomes the duty of the Court to apply the Directive Principles in interpreting the Constitution and the laws. The Directive Principles should serve the Courts as a code of interpretation. Fundamental Rights should thus be interpreted in the light of the Directive Principles and the later should	 whenever and wherever possible	 be read into the former. Every law attacked on the ground of infringement of a Fundamental Right should	 among other considerations	 be examined to find out if the law does not advance one or other of the Directive Principles or if it is not in discharge of some of the undoubted obligations of the State	 constitutional or otherwise	 towards its citizens or sections of its citizens	 flowing out of the preamble. the Directive Principles and other provisions of the Constitution. So	 we have it that the Constitutional goal is the establishment of a Socialist Democracy which Justice	 economic	 social and political 258 is secure and all men are equal and have equal opportunity. Inequality	 whether of status	 facility or opportunity	 is to end	 privilege is to cease and exploitation is to go. The under privileged	 the deprived and the exploited are to be protected and nourished so as to take their place in an egalitarian society. State action is to be towards those ends. It is in this context that article 16 has to be interpreted when State action is questioned as contravening article 16. Let us now take a look at article 16(1) and Art 16(4). article 16(1) guarantees equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State. To the class of citizens who are economically and socially backward this guarantee will be no more than mere wishful thinking	 and mere 'vanity. wind and confusion"	 if it is not translated into reality by necessary state action to protect and nurture such class of citizens so as to enable them to shake off the heart crushing burden of thousand years ' deprivation from their shoulders and to claim a fair proportion of participation in the Administration. Reservation of posts and all other measures designed to promote the participation of The Scheduled Castes and the Scheduled Tribes in the Public Services at all levels are in our opinion necessary consequences flowing fro the Fundamental Right guaranteed by article 16(1)S This very idea is emphasised further by article 16(4). article 16(4) is not in the nature of an exception to article 16(1). It is a facet of article 16(1) which fosters and furthers the idea of equality of opportunity with special reference to an under privileged and deprived class of citizens to when egalite de droit (formal or legal equality) is not egalite de fait (practical or factual equality). It is illustrative of what the State must do to wipe out the distinction between egalite de droit and egalite de fait. It recognises that the right to equality of opportunity includes the right of the underprivileged to conditions comparable to or compensatory of those enjoyed by the privileged. Equality of opportunity must be such as to yield 'Equality of Results ' and not that which simply enables people	 socially and economically better placed	 to win against the less fortunate	 even when the competition is itself otherwise equitable. John Rawls in 'A Theory of Justice ' demands the priority of equality in a distributive sense and the setting up of the Social System "so that no one gains or loses from his arbitrary place in the distribution of natural assets or his own initial position in society without giving or receiving compensatory advantages in return". His basic principle of social justice is: "All social primary goods liberty and opportunity	 income and wealth	 and the bases of self respect are to be distributed equally unless an unequal distribution of any or all these goods is to the advantage of the least 259 favoured". One of the essential elements of his conception of social A justice is what he calls the principle of redress: "This is the principle that undeserved inequalities call for redress; and since inequalities of birth and natural endowment are undeserved	 these inequalities are somehow to be compensated for". Society must	 therefore	 treat more favourably those with fewer native assets and those born into less favourable social positions. If the statement that 'Equality of opportunity must yield Equality of Results ' and if the fulfillment of Articles 16(1) in article 16(4) ever needed a philosophical foundation it is furnished by Rawls ' Theory of Justice and the Redress Principle. The interpretation of articles 16(1) and 16(4) came up for consideration in several cases before this Court. Perhaps the most important of them is State of Kerala & Anv. vs N. M. Thomas & Ors.	(1) which was decided by a Bench of seven Judges. The question was whether a certain rule which gave a longer period of exemption to members belonging to Scheduled Castes and Scheduled Tribes than to others from passing certain departmental tests in order to be eligible for promotion from the Post of Lower Division Clerk to that of Upper Division Clerk was not violative of article 16(1) of the Constitution. The Court by a majority of five to two upheld the rule as valid. Ray	 C. J.	 observed: "The rule of equality within Articles 14 and 16(1) will not be violated by a rule which will ensure equality of representation in the services for unrepresented classes after satisfying the basic needs of efficiency of administration. Article 16(2) rules out some basis of classification including race	 caste	 descent	 place of birth etc. Article 16(4) clarifies and explains that classification on the basis of backwardness does not fall within Article 16(2) and is legitimate for the purposes of Article 16(1). If preference shall be given to a particular under represented community other than a backward class or under represented State in an All India Service such a rule will contravene Article 16(2). A similar rule giving preference to an under represented backward community is valid and will not contravene articles 14	 16(1) and 16(2). Article 16(4) removes any doubt in this respect". (I) ; @930 933. 260 "The classification of employees belonging to Scheduled Castes and Scheduled Tribes for allowing them an extended period of two years for passing the special tests for promotion is a just and reasonable classification having rational nexus to the object of providing equal opportunity for all citizens in matters relating to employment or appointment to public office. " xx xx xx "The Constitution makes a classification of Scheduled Castes and Scheduled Tribes in numerous provisions and gives a mandate to the State to accord special or favoured treatment to them." xx xx xx "Article 335 of the Constitution states that claims of members of the Scheduled Castes and Scheduled Tribes shall be taken into consideration in the making of appointments to the services and posts in connection with affairs of the State consistent with the maintenance of efficiency of administration. The impugned rule and the impugned orders are related to this constitutional mandate." "Our constitution aims at equality of status and opportunity for all citizens including those who are socially	 economically and educationally backward. The claims of members Or backward classes require adequate representation in legislative and executive bodies. If members of Scheduled Castes and Tribes	 who are said by this Court to be backward classes	 can maintain minimum necessary requirement of administrative efficiency	 not only representation but also preference may be given to them to enforce equality and to eliminate inequality. Articles 15 (4) and 16(4) bring out the position of backward classes to merit equality Special provisions are made for the advancement of backward classes and reservations of appointments and posts for them to secure adequate representation. These provisions will bring out the content of equality guaranteed by Articles 14	 15(1) and 16(1). The basic concept of equality is equality of opportunity for appointment. Preferential treatment for members of backward classes with due regard to administrative efficiency alone	 can mean equality of opportunity for all citizens. Equality under 261 Article 16 could not have a different content from equality under Article 14. Equality of opportunity for unequals can only mean aggravation of inequality Equality of opportunity admits discrimination with reason and prohibits discrimination without reason. Discrimination with reasons means rational classification for differential treatment having n nexus to the constitutionally permissible object. Preferential representation for the backward classes in services with due regard to administrative efficiency is permissible object and backward classes are a rational classification recognised by our Constitution. Therefore	 differential treatment in standards of selection are within the concept of equality". xx xx xx xx "All legitimate methods are available for equality of opportunity in service under Article 16(1). Article 16(1) is affirmative whereas Article 14 is negative in language. Article 16(4) indicates one of the methods of achieving equality embodied in Article 16(1)". Equally illuminating observations were made by Mathew	 J.	 Beg. 	 J.	 Krishna Iyer	 J.	 and Fazal Ali	 J.	 in their separate concurring opinions but I do not propose to extract them in the interest of space. It is enough to mention that all five learned judges who constituted the majority were emphatic in repudiating the theory (propounded in earlier cases) that article 16(4) was in the nature of an exception to article 16(1). All were agreed that article 16(4) was a facet	 an illustration or a method of application of article 16(1). So	 it is now no longer necessary to apologetically explain laws aimed at achieving equality as permissible exceptions; it can now be boldly claimed that such laws are necessary incidents of equality. It all began with The General Manager)	 Southern Railway vs Rangachari(1). Two circulars issued by the Railway Board reserving selection (promotional) posts in Class III of the Railway Service in favour of the members of the Scheduled Castes and the Scheduled Tribes	 were questioned in that case as offending article 16. It was contended that article 16(4) applied only to reservation of posts at the stage of initial appointment and not to promotional posts. The contention was rejected and it was held that article 16(4) applied at the stage of initial appointment as well as at the stage of promotion by selection. It was in the case that observations were made to the (1) ; 262 effect that article 16(4) was in the nature of an exception to article 16(1)	 but	 as we have seen such a view is no longer tenable in view of State of Kerala & Anr. vs N. M. Thomas & Ors. (supra). Much of the argument of the learned counsel for the petitioners was anchored to	 T. Devodasan vs Union of India(z & Anr.(1) 17 1/2% of vacancies in an establishment were reserved for members of the scheduled Castes and Scheduled Tribes. Alongside the reservation rule	 there operated what is known as "the carry forward rule" familiar to all Govt. employees and those connected with 'service problems '. The carry forward rule so operated in the particular case that out of 45 appointments made by the Government 29 were from among the candidates belonging to the Scheduled Castes and Scheduled Tribes. In other words the reservation Came to 65% which was far in excess of the 177% originally contemplated by the Reservation rule. In those circumstances	 a Constitution Bench of this Court (Subba Rao	 J. dissenting) declared the carry forward rule bad. The Court did not strike down the carry forward rule on the ground that it was inherently vicious or on the hypothetical consideration that it was bound to lead to vicious results in the future if permitted to operate without inhibition. The learned judges indicated that the repercussions of such a rule would have to be watched from year to year. Another case upon which the petitioners placed reliance was M. R. Balaji & Ors. vs State	 of Mysore(2). In that case the percent age of seats reserved in the Engineering and Medical colleges for the educationally and socially backward classes and Scheduled Castes and Scheduled Tribes came to 68% leaving only 32% of the seats for the merit pool. The Court held that generally and broadly reservation should not exceed 50%. The actual percentage was to depend upon the relevant prevailing circumstances in each case. As the reservation in that case for exceeded what was generally and broadly permissible	 the reservation was held to be bad. There again the Court was concerned directly with the immediate	 actual	 practical result of the Reservation rule. In A. Peeriakaruppan	 etc. Y. State of Tamil Nadu & Ors. 	(3) reservation of 41% of the seat in medical college in the State of (1) ; (2) [1963] Suppl. I SCR 439. (3) [1971] 2 SCR 430 @ 441 442. 263 Tamil Nadu for students coming from socially and educationally back ward classes was upheld. Hegde	 J.	 observed (at p. 441 442): "There is no basis for the contention that the reservation made for backward classes is excessive. We were not told why it is excessive. Undoubtedly we should not forget that it is against the immediate interest of the Nation to exclude from the portals of our medical colleges qualified and competent students but then the immediate advantages of the Nation have to be harmonised with its long range interests. It cannot be denied that unaided many sections of the people in this country cannot compete with the advanced sections of the Nation. Advantages secured due to historical reasons should not be considered as fundamental mental rights. Nation 's interest will be best served taking a long range view if the backward classes are helped to march forward and take their place in line with the advanced sections of the people. That is why in Balaqi 's case [1931] Suppl 1 SCR (439)	 this Court held that the total of reservations for backward classes	 scheduled castes and scheduled tribes should not ordinarily exceed 50% of the available seats. In the present case it is 41%. On the material before us we are unable to hold that the said reservation is excessive". In State of Punjab vs Hiralal & Ors. 	(l) a rule reserving the first out of every ten vacancies to a member of the Scheduled Castes and Scheduled Tribes and providing for 'carry forward ' of the vacancy if suitable candidate was not available was struck down by the High Court by visualising various hypothetical cases which could lead to anomalous situations in which a person getting the benefit of reservation may jump over the heads of several of his seniors not only in his own grade but even in higher grades. This Court reversed the decision of the High Court observing: "The extent of reservation to be made is primarily a matter for the State to decide. By this we do not mean to say that the decision of the State is not open to judicial re view. The reservation must be only for the purpose of giving adequate representation in the service to the Scheduled Castes	 Scheduled Tribes and Backward Classes". xx xx (1) ; @ 272	 273	 274. 264 "The mere fact that the reservation made may give extensive benefits to some of the persons who have the benefit of the reservation does not by itself make the reservation bad. The length of the leap to be provided depends upon the gap to be covered". xx xx xx xx "There was no material before the High Court and there is no material before us from which we can conclude that the impugned order is violative of article 16(1). Reservation of appointments under article 16(4) cannot be struck down on hypothetical grounds or on imaginary possibilities. He who assails the reservation under that article must satisfactorily establish that there has been a violation of article 16(1)". The report of the Commissioner for Scheduled Castes and Scheduled Tribes for 1977 78 and the 'Reports on the progress made in the intake of Scheduled castes and Scheduled Tribes against vacancies reserved for them in recruitment and promotion categories in the Rail ways ' for the half years ending March 31	 1974	 March 31	 1975	 September 30	 1976	 March 31	 1977 and September 30	 1979 were placed before us. they reveal how painfully slow and woefully in significant has been progress achieved by the members of the Scheduled Castes and Scheduled Tribes in the matter of their participation in the Railway administration. My brother Krishna Iyer J has extracted some of the facts and figures. I do not think it is necessary for me to refer to them over again. It is sufficient to say that members of the Scheduled Castes and Scheduled Tribes far from acquiring any monopolistic or excessive representation over any category of posts (other than sweepers) are nowhere near being adequately represented. Neither the Reservation rule nor the 'carry forward for three years ' rule has resulted in any such 'disastrous ' consequences. The complaint of the petitioners that the circulars and orders had resulted in excessive representation of the Scheduled Castes and Scheduled Tribes is without foundation generally or with reference to any particular year. One of the contentions vehemently submitted by the learned counsel for the petitioners was that efficiency of administration would suffer and safety of the travelling public would consequently be jeopardised if reservations were made and promotions affected in the manner sought to be done by the Railway Board. This is claimed by the respondents to be no more than a bogey. In the counter affidavit filed on behalf of the Railway Board it has been pointed out that minimum standards arc insisted upon for every appointment 265 and in the case of candidates wanting in requisite standards	 those h with the highest marks are given special intensive training to enable them to come up to the requisite standards. In the case of posts which involve the safety of movement of trains there is no relaxation of standards in favour of candidates belonging to Scheduled Castes and Scheduled Tribes and they are required to pass the same rigid tests as other candidates. Therefore	 we see that when posts whether at the stage of initial appointment or at the state of promotion are reserved or other preferential treatment is accorded to members of the Scheduled Castes	 Scheduled Tribes and other socially and economically backward classes	 it is not a concession or privilege extended to them	 it is in recognition of their undoubted Fundamental Right to Equality of Opportunity and in discharge of the Constitutional obligation imposed upon the state to secure to all its citizens 'Justice	 social	 economic and political ' and 'Equality to status and opportunity '	 to assure 'the dignity of the individual ' among all citizens	 to 'promote with special D. care the educational and economic interests of the weaker section of the people '	 to ensure their participation on equal basis in the administration of the affairs of the country and generally to foster the ideal of a 'Sovereign	 Socialist	 Secular	 Democratic Republic '. Every lawful method is permissible to secure the due representation of the Scheduled Castes and Scheduled Tribes in the public Services. There is no fixed ceiling to reservation or preferential treatment in favour of the Scheduled Castes and Scheduled Tribes though generally reservation may not be far in excess of fifty percent. There is no rigidity about the fifty percent rule which is only a convenient guideline laid down by Judges. Every case must be decided with reference to the present practical results yielded by the application of the particular rule of preferential treatment and not with reference to hypothetical results which the application of the rule may yield in the future. Judged in the light of this discussion I am unable to find anything illegal or unconstitutional in any one of the impugned orders and circulars. Each order and circular has been individually discussed by my brother Krishna Iyer J with whose reasoning and conclusions I agree and to which I wish to add no more. PBR Petitions dismissed.

In so far as the initial recruitment and later promotion to classes II	 III and IV are concerned	 the Railway Administration provided for reservation of certain percentage of vacancies for candidates belonging to the Scheduled Castes and Scheduled Tribes. Since	 despite the special provision the intake of these communities into the Railway Services continued to be negligible further concessions and relaxations were offered from time to time to members belonging to the Scheduled Castes and Scheduled Tribes. Even so	 in many cases the vacancies reserved for them remained unfilled. Yet another step taken by the Railway Administration to keep open the reserved vacancies was to adopt a policy of "carry forward" of the unfilled reserved vacancies for at least three years. In obedience to the policy decision of the Ministry of Home Affairs	 the Railway Board issued certain directives designed to protect and promote the interest of members of the Scheduled Castes and Scheduled Tribes in the matter of their employment in the Railway Administration. The policy directive of reserving certain percentage of posts in favour of these communities having not proved effective	 the Railway Board altered the rules "with a view to securing increased representation of Scheduled Castes and Scheduled Tribes in the Railway Services" (Annexure D). The Railway Board authorised the recruiting bodies to slur over low places obtained by Scheduled Castes and Scheduled Tribes candidates except where it was found that the minimum standard necessary for the maintenance of efficiency of the administration had not been reached. The appointing authorities were directed to give additional training and coaching to the recruits so that they might come up to the standard of other recruits appointed alongwith them. Likewise where direct recruitment	 otherwise than by examination	 was provided for	 the Railway Board directed the selection of Scheduled Castes and Scheduled Tribes candidates fulfilling a lower standard of suitability than from other communities	 so long as the candidates had the prescribed minimum educational and technical qualifications and the appointing authorities were satisfied that the lowering of standards would not unduly affect the maintenance of efficiency of administration. In the case of selection posts the Railway Board decided that promotions from class IV to class III and from class III to class II were of the nature of direct recruitment and the prescribed quota of reservation for Scheduled Castes and Scheduled Tribes should be provided as in direct recruitment. This reser 186 vation was confined to 'selection posts '. In regard to filling of "general posts" in class III it was stated that they were in the nature of direct recruitment and the reservation for Scheduled Castes and Scheduled Tribes as applicable to direct recruitment should be applied. (Annexure F). In 1969 the Railway Board further revised their policy in regard to the reservation and other concessions to the Scheduled Castes and Scheduled Tribes candidates in posts filled by promotion (Annexure H). The circular stated that in promotion by selection from class III to class II	 if a member of the Scheduled Castes and Scheduled Tribes was within the zone of eligibility the employee would be given one grading higher than the grading otherwise assignable to him on the basis of his record of service. In April	 1970 the percentage of vacancies to be reserved for Scheduled Castes and Scheduled Tribes was raised from 121/2% and 5% to 15% and 71/2% respectively (Annexure I). By the same order the "carry forward" rule was altered from 2 to 3 years. In 1973 the Railway Board issued a directive stating that the quota of 15% and 71/2% for Scheduled Castes and Scheduled Tribes may be provided promotion to the categories and posts in classes I	 II	 III and IV filled on the basis of the seniority cum suitability provided the element of direct recruitment to those grades does not exceed 50% (Annexure K). In August	 1974 the Railway Board further directed that if the requisite number of Scheduled Castes and Scheduled Tribes candidates were not available for being placed on the panel in spite of the various relaxations the best among them i.e. those who secure highest marks should be earmarked for being placed on the panel to the extent vacancies had been reserved in their favour. The Scheduled Castes and Scheduled Tribes candidates so earmarked might be promoted ad hoc for a period of six months against the vacancies reserved for them. During the period of six months the administration was asked to give them all facilities for improving their knowledge and for coming upto the requisite standard. The procedure was required to be applied in cases of promotion to the posts filled on the basis of seniority cum suitability (Annexure N). A further modification to the then existing rules was made by Annexure 'O ' which stated that "reservations in posts filled by promotion under the existing scheme would be applicable to all grades or services where the element of direct recruitment	 if any	 does not exceed 66 2/3% as against 50% as at present". It was contended on behalf of the petitioners that Scheduled Castes cannot be a favoured class in the public services because (i) they are "castes" and cannot claim preference qua castes unless specially saved by Article 16(4) which speaks of "class" and not "castes"	 (ii) that Article 16(4) could not apply to promotional levels and (iii) efficiency of administration envisaged by Article 335 had been jeopardised by the impugned circulars which fomented frustration among the civil services and produced inefficiency by placing men of lower efficiency and less experience in higher posts. 187 A preliminary objection was raised that since the first petitioner was an unrecognised union	 it was not a "person aggrieved" and so its petition was unsustainable. Dismissing the petitions [Per majority Krishna Iyer and Chinnappa Reddy	 JJ	 Pathak J. concurring in the result with reservation on certain questions] There is nothing illegal or unconstitutional in the impugned orders. [Per Krishna Iyer	 J] The argument that since the first petitioner was an unrecognized association the petition is not sustainable must be overruled because whether the petitioners belonged to a recognised union or not	 the fact remains that a large body of persons with a common grievance exists and they approached this Court under Article 32. Our current processual jurisprudence is broad based and people oriented and envisions access to justice through "class actions"	 "public interest litigation" and "representative proceedings". The narrow concept of cause of action and person aggrieved and individual litigation is becoming obsolescent in some jurisdictions. [224 G H] The well settled position in law is that the State may classify	 based upon substantial differentia	 groups or classes and this process does not necessarily spell violation of Articles 14 to 16. Therefore	 in the present case if the Scheduled Castes and Scheduled Tribes stand on a substantially different footing they may be classified groupwise and treated separately. [232 B C] The fundamental right of equality of opportunity has to be read as justifying the categorisation of Scheduled Castes and Scheduled Tribes separately for the purpose of "adequate representation" in the services under the State. The object is constitutionally sanctioned in terms as Article 16(4) and 46 specificate. The classification is just and reasonable. [233 G H] Apart from Article 16(1)	 Article 16(2) expressly forbids discrimination on the ground of caste and here the question arises as to whether the Scheduled Castes and Tribes are castes within the meaning of Article 16(2). Assuming that there is discrimination	 Article 16(2) cannot be invoked unless it is predicated that the Scheduled Castes are "castes". There are sufficient indications in the Constitution to suggest that the Scheduled Castes are not mere castes. They may be something less or something more and the time badge is not the fact that the members belong to a caste but the circumstance that they belong to an indescribably backward human group. [234 A C] Articles 14 to 16 form a Code by themselves and contain a constitutional fundamental guarantee. The Directive Principles which are fundamental in the governance of the country enjoin upon the State the duty to apply that principle in making laws. Article 46 obligates the State the promote with special care the educational and economic interests of the weaker sections of the people and in particular of the Scheduled Castes and the Scheduled Tribes. Article 46 read with Article 16(4) makes it clear that the exploited lot of the harijan groups in the past shall be extirpated with special care by the State. A C] 188 At the same time reservations under Article 16(4) and promotional strategies under Article 46 should not be used to imperil administrative efficiency in the name of concessions to backward classes. The positive accent of Article 335 is that the claims of these communities to equalisation of representation in services under the State shall be taken into consideration. The negative element of this Article is that measures taken by the State pursuant to the mandate of Articles 16(4)	 46 and 335 shall be consistent with and not subversive of the maintenance of efficiency of administration. [211 D F] Under Article 341	 Scheduled Castes become such only if the President specifies any castes	 races or tribes or parts or groups within castes	 races or tribes for the purpose of the Constitution. It is the socioeconomic backwardness of a social bracket that is decisive and not mere birth in a caste. [212 A] Annexure F relates only to selection posts and has been expressly upheld in Rangachari 's case. The quantum of reservation is not excessive; the field of eligibility is not too unreasonable; the operation of the reservation is limited to selection posts and no relaxation of qualifications is written into the circular except that candidates of the Scheduled Castes and Scheduled Tribes communities should be judged in a sympathetic manner. Moreover administrative efficiency is secure because there is a direction to give such staff additional training and coaching	 to bring them upto the standard of others. [239 F G] There is no vice in giving one grade higher than is otherwise assignable to an employee. based on the record of his service rendering the promotional prospects unreasonable because this concession is confined to only 25% of the total number of vacancies in a particular grade or post filled in a year and there is no rampant vice of every harijan jumping over the heads of others. More importantly	 this is only an administrative device of showing a concession or furtherance of prospects of selection. Even as under Articles 15(4) and 16(4) lesser marks are prescribed as sufficient for these communities or extra marks are added to give them an advantage	 the regrading is one more method of boosting the chances of selection of these communities. The prescribed minimum qualification and standard of fitness are continued even for Scheduled Castes and Scheduled Tribes under Annexure H. [240 B D] Annexure I is unexceptionable since all that it does is to readjust the proportion of reservation in conformity with the latest census. [240 E F] Similarly "carry forward" raised from two years to three years cannot be struck down. There is no prospect	 even if the vacancies are carried forward	 of sufficient number of Scheduled Castes and Scheduled Tribes candidates turning out to fill them. Moreover	 there is a provision that if a sufficient number of candidates from these communities are not found	 applicants from the unreserved communities would be given appointment provisionally. After three years these vacancies cease to be reserved. [240 G A] Even in Devadasan 's case	 this Court has laid down the proposition that under Article 16(4) reservation of a reasonable percentage of posts for member of the Scheduled Castes and Scheduled Tribes is within the competence of the State. What was struck down was that the reservations should not be so excessive as to create a monopoly or to disturb unduly the legitimate claims of other communities. By this rule there is no danger of the total vacancies 189 being gobbled up by the harijan/girijan groups virtually obliterating Article 16(1). The problem of giving adequate representation to backward classes under Article 16(4) is a matter for the Government to consider	 bearing in mind the need for a reasonable balance between the rival claims. [241 B F] Subject to the condition that the carry forward rule shall not result in any given year in the selection or appointment of Scheduled Castes and Scheduled Tribes candidates considerably in excess of 50%	 the Annexure I is upheld. [242 E] There is nothing unreasonable or wrong in Annexure J. Once the parameters of reservation are within the framework of the fundamental rights	 minute scrutiny of every administrative measure is not permissible. [242 F] Annexure K is beyond reproach. As between selection and non selection posts the role of merit is functionally more relevant in the former than in the latter. If in selecting top officers	 posts could be reserved for Scheduled Castes and Scheduled Tribes with lesser merit it cannot rationally be argued that for the posts of peons	 or lower division clerks reservation would spell calamity. The part that efficiency plays is far more in the case of higher posts than in the appointments to the lower posts. [243 D] Dilution of efficiency caused by the minimal induction of a small percentage of reserved candidates cannot affect the over all administrative efficiency significantly. Moreover	 care has been taken to give in service training and coaching to correct the deficiencies. [244 B C] [Chinnappa Reddy	 J concurring] The preamble to the Constitution of India proclaims the resolution of the people to secure to all its citizens justice	 social	 economic and political	 equality of status and opportunity and to promote fraternity assuring the dignity of the individual. The right to equality before the law and equality of opportunity in the matter of public employment are guaranteed as fundamental rights. The State is enjoined upon by the Directive Principles to promote the welfare of the people	 to endeavour to eliminate inequalities in status	 facilities and opportunities and special provisions have been made	 in particular	 for the protection and advancement of the Scheduled Castes and Scheduled Tribes in recognition of their low social and economic status and their failure to avail themselves of any opportunity of self advancement. In short the constitutional goal is the establishment of a socialist democracy in which justice economic	 social and political is secure and all men are equal and have equal opportunity. Inequality whether of status	 facility or opportunity is to end	 privilege is to cease and exploitation is to go. The under privileged	 the deprived and the exploited are to be protected and nourished so as to take their place in an egalitarian society. State action is to be towards those ends. It is in this context that Article 16 has to be interpreted when State action is questioned as contravening Article 16. [255 A F] A Constitution	 such as ours	 must receive generous interpretation so as to give an its citizens the full measure of justice so proclaimed. While interpreting the Constitution the expositors must concern themselves not so much with words as with the spirit and sense of the Constitution which could be found in the Preamble the Directive Principles and other such provisions. [256 G] 190 At one time it was assumed that because the fundamental rights are enforce able in a court of law while Directive Principles are not	 the former were superior to the latter	 that way of thinking has become obsolete. The current thinking is that while Fundamental Rights are primarily aimed at assuring political freedom to the citizens against excessive State action	 the Directive Principles are aimed at securing social and economic freedoms by appropriate State action. The Directive Principles are made unenforceable in a limited sense because no Court can compel a Legislature to make laws. But that does not mean that they are less important than Fundamental Rights or that they are not binding on the various organs of the State. They are all the same fundamental in the governance of the country and it shall be the duty of the State to apply these principles in making laws. The Directive Principles should serve the Courts as a Code of Interpretation. Every law attacked on the ground of infringement of Fundamental Right should be examined to see if the impugned law does not advance one or other of the Directive Principles or if it is not in the discharge of some of the undoubted obligations of the State towards its citizens flowing out of the Preamble	 the Directive Principles and other provisions of the Constitution. [257 A G] Reservation of posts and all other measures designed to promote the participation of the Scheduled Castes and Scheduled Tribes in public services at all levels are a necessary consequence flowing from the Fundamental Rights guaranteed by Article 16(1). This very idea is emphasized further by Article 16(4) which is not in the nature of an exception to Article 16(1) but a facet of that Article. In the State of Kerala vs N.M. Thomas the court has repudiated the theory propounded in earlier cases that Article 16(4) is in the nature of an exception to Article 16(1). It is no longer correct to say that laws aimed at achieving equality as permissible exceptions. Such laws are necessary incidents of equality.

[1976] 1 S.C.R. 906 @ 930 933 and The General Manager	 Southern Railway vs Rangachari [1962]2 S.C.R. 586 referred to. The figures quoted from the report of the Commissioner of Scheduled Castes and Scheduled Tribes for the year 1977 78 reveal how slow and insignificant the progress achieved by the members of these communities in the matter of participation in the Railway Administration had been. Far from acquiring any monopolistic or excessive representation over any category of posts these communities are nowhere near being adequately represented. Neither the reservation rule nor the "carry forward" rule for these years has resulted in any such disastrous consequence. Therefore	 the complaint of the petitioners that the circulars had resulted in excessive representation of these communities is without foundation generally or with reference to any particular year. [246 D G] There is no substance in the argument that efficiency of administration would suffer if the Railway Board 's directives were followed in the matter of reservations and promotions. The Railway Board had stated that minimum standards were insisted upon for every appointment and in the case of candidates wanting in requisite standards of efficiency those with higher marks were given special intensive training to enable them to come up to the requisite standards. In the case of posts which involved safety of movement of trains there was no 191 relaxation of standards in favour of candidates belonging to Scheduled Castes and Scheduled Tribes and they were required to pass the same rigid tests as others.[265 A B] There is no fixed ceiling to reservation or preferential treatment in favour of the Scheduled Castes and Scheduled Tribes though generally reservation may not be far in excess of 50% about which there is no rigidity. Every case must be decided on its own facts. [265 E] There is nothing illegal or unconstitutional in any one of the impugned orders and circulars. [265 G] [Pathak J concurring in the result with reservation on certain questions.] Article 46 of the Constitution enjoins upon the State to treat with special care the educational and economic interest of the weaker sections of the people and in particular the Scheduled Castes and Scheduled Tribes. One of the modes in which the economic interest of these communities can be promoted is by reservation of appointments or posts in their favour in services under the State where they are not adequately represented. By virtue of Article 16(4)	 when the State intends to make reservation of appointments or posts in favour of these communities in services under it nothing in Article 16 prevents it from doing so. Article 335 provides that claims of the members of these communities shall be taken into consideration in the making of appointments to services and posts in connection with the affairs of the Union or a State. But such consideration must be consistent with the maintenance of efficiency of administration which is regarded as paramount. It is dictated by the common good and not of a mere section of the people. Therefore	 whatever is done in considering the claims of Scheduled Castes and Scheduled Tribes must be consistent with the need for maintenance of efficiency of administration. This Article contains a single principle	 namely	 the advancement of Scheduled Castes and Scheduled Tribes but through modes and avenues which must not detract from the maintenance of an efficient administration. [250 B H] For securing an efficient administration the governing criterion in the matter of appointments to posts under the State is excellence and the emphasis is solely on quality. The selection is made regardless of religion	 race	 caste	 sex	 descent	 place of birth or residence. However	 a quota of the posts may be reserved in favour of backward citizens. But the interests of efficient administration require that at least half the total number of posts be kept open to attract the best of the nation 's talent. If it was otherwise an excess of the reserved quota would convert the State service into a collective membership predominantly of backward classes. The maintenance of efficiency of administration is bound to be adversely affected if general candidates of high merit are correspondingly excluded from recruitment. Viewed in that light the maximum of 50% for reserved quota appears fair and reasonable	 just and equitable violation of which would contravene Article 335. [251 B D] M.
