Summarize the following court judgment. Appeal No. 2063 of 1973. Appeal by special leave from the judgment and decree dated the 25th July. 1973 of the Calcutta High Court in Appeal from Appellate Decree No. 1193 of 1972. Civil Appeal No. 1304 of 1973. From the judgment and order dated the 3rd February	 1972 of the Calcutta High Court in L.P.A. No. 14 of 1969. P. Chatterjee and Rathin Das	 for the appellant (In C. A. 2063/73). Urmila Kapoor and Shobha Dikshit	 for the respondent (In C.A. No. 2063/73). P.K. Chatterjee	 G. section Chatterjee	 and Sukumar Basu	 for the Advocate General for the State of West Bengal. Sukumar Ghose	 for the appellants. (In C.A. No. 1304/73). D. N. Mukherjee	 for the respondents (in C.A. No. 1304/73). The judgment of M. H. Beg and V. R. Krishna Iyer	 JJ was delivered by Krishna Iyer	 J. P. K. Goswami	 J. gave a separate Opinion. KRISHNA IYER	 J. Calcutta or Cochin	 for the urban people of India	 the shocking scarcity of a roof to rest one 's tired bones is an L346SupCI/75 778 unhappy problem of social justice that compels control of rent. and eviction laws. In the case now before us	 attacking the constitutionality of legislation handcuffing the landlord proprietariat 's right of eviction	 the law has to be tested not merely by the cold print of article 19(1)(f) but also by the public concern of article 19(5) and the	 compassionate animus of article 39	 Parts III and IV of the Constitution together constitute a complex of promises the nation has to keep and the legislation challenged before us is in partial fulfilment of this tryst with the people. These observations become necessary in limine since counsel for the respondents dismissed the concept of social justice as extraneous to an insightful understanding of the section invalidated by the High Court	 while we think that judicial conscience is not a mere matter of citations of precedents but of activist appraisal of social tears to wipe out which the State is obligated under the Constitution. The two appeals before us	 raising substantially identical points	 have been heard together and are being disposed of by a common judgment. Both of them stem from a decision of the Calcutta High Court reported as Sailendra Nath vs section E. Dutt(1). One of the decisions under appeal (C.A. 2063 of 1973) was rendered by a Single Judge of the High Court following a Division Bench ruling of the same Court (i.e.	 the one reported as Sailendra Nath vs section E. Dull) since he was obviously bound by it. A provision imparting some sort of retroactivity to a 1969 legislative amendment implanting additional restrictions on eviction of premises under the earlier West Bengal rent control law has been voided by the High Court in the judgment& under appeal. The aggrieved tenant in each case has appealed and the State	 not being directly a party to the legislation	 has entered appearance to support	 the legislation and to challenge the Calcutta decision to the extent it has invalidated the retrospective part of the statute. Welfare legislation calculated to benefit weaker classes	 when their vires is challenged in Court	 casts an obligation on the State	 particularly when notice is given to the Advocate General	 to support the law	 if necessary by a Brandeis brief and supply of socio economic circumstances and statistics inspiring the enactment. Courts cannot	 on their own	 adventure into social research outside the record and if Government lets down the Legislature in Court by not illumining the provisions from the angle of the social mischief or economic menace sought to be countered	 the victims will be the class of beneficiaries the State professed to protect. In this case	 we are unable to compliment the State or the Advocate General from this point of view. It may happen that when the Court decides against the validity of a measure or order because Government fails to bring the socially relevant totality of facts	 it is used Is an alibi by (1) A.1 R. 779 he latter for the misfortune. Courts cannot help cover up the Executive 's drowsy default or half hearted help in making the socioconomic conspectus available. The West Bengal Premises Tenancy Act	 1956 (Act XII of 956) (for short	 referred to as the basic Act) clamped down several restrictions on ejectment of tenants by landlords from buildings	 the policy behind it being alleviation of the lot of the weaker segment of the urban community without their own homes in the context of the scarcity of accommodation and the colossal sociceconomic upheaval which would follow if unbridled evictions were allowed. The temptation to evict or rack rent under scarcity conditions is an irresistible evil in our economic order and it is an all India phenomenon that the social conscience of the State Legislatures has responded to this large scale threat by effective control measures. Indeed	 for decades now	 every State in India has on	 the statute book rent control law and	 what is more pertinent to the present case	 tactics of circumvention have compelled the enactment of additional safeguards from time to time by vigilant statutory measures. West Bengal	 a populous State	 with an overcrowded city choked by the largest human congregation in the country	 enacted the basic Act whereby the plenary right of landlords to recover possession of their buildings was shackled in many ways. Industrial growth and other factors induced demographic congestion such as was witnessed in the urban areas of that State. Consequently	 the legislature	 was faced with a fresh danger in the shape of ingenious transfers of ownership of buildings by indigenous but indigent landlords and the transferees resorting to eviction on a large scale equipped as they were with better financial muscles and motivated as they were by hope of speculative returns from their investments oil eviction. Presumably	 the phenomenal increase of the menance of eviction by the new species of transferee owners of building was countered by a legislative measure the West Bengal Premises Tenancy (Second Amendment) Act	 1969 (Act XXXIV of 1959) (hereinafter referred to as the amendment Act). By this legislation the new class of transferee landlords was subject to a stringent trammel viz. that they should not sue for eviction within three years of the date of transfer (We are not immediately concerned here with certain other changes effected by the Amendment Act). The social objective and the practical effect of this fetter will be con Court has upheldthis provision which is now contained in section 13(3A) sidered briefly the little later. Suffice it to say at this stage the High of the basic Act. However 	 while holding the provision substantial intra vires the Court has invalidated the giving effect to the provision to pending suits and appeals. Such limited retrospectivity had been incorporated by section 13 of the amending Act and	 if the law were only prospective the landlords in the two cases who had initiated their litigation several years prior to the enactment of the Amendment Act would be free from the three year interdict and the other extra restrictions. Once the embargo is out of their way	 the decree 	 for eviction they have secured must stand. On tile contrary	 if the restriction on eviction by the transferee landlords were to operate on 780 pending litigation the appellants tenants are immune to eviction in the current proceedings as they now stand. Thus the short constitutional issue is as to whether section 13(3A) of the basic Act to the extent it applies to pending litigation on the strength of section 13 of the Amending Act is violative of articles 14 and 19(1)(f) of the Constitution	 weapons relied upon for the attack before the High Court	 and here. We will proceed to consider the constitutional vulnerability of this limb of the protective legislation. By way of anticipating our conclusion we may also pose the problem whether sections 1 3 and 4 of the Amendment Act can be validly implemented vis a vis pending actions in any other just manner which will preserve the additional protection	 minimise multiplicity of litigation and make law and justice bedfellows in the &hanged statutory circumstances. Some background observations to appreciate the contest in court are necessary. No social realist will deny the frightful dimensions of the problem of homeless families and precarious tenancies; and if the Directive Principles of State Policy are not to be dismissed by the masses as a 'teasing illusion and promise of unreality '	 curtailment	 in public interest	 of such extreme rights of the landlord as are 'red in tooth and claw ' is a constitutional compulsion. The Court	 informed by this sore economic situation and reinforced by the initial presumption of constitutionality	 hesitates to strike a socially beneficial statute dead	 leading to escalation of the mischief to suppress which the House legislated unless	 of course	 a plain breach of the fundamental right of the citizen is manifest. The perspective of the amending Act is sketched by the High Court in lurid language : "The scarcity of accommodation is a burning problem	 not only of the State of West Bengal but of the other States as well. Keeping pace with the needs of the gradually swelling population of West Bengal	 new buildings have not been built owing to abnormal high price of land and materials. A large majority of the people of West Bengal live in those premises at the mercy of the landlords. " The explosive import of neglecting such a distressing urban development reasonably obliges the State to impose drastic restrictions on landlords ' right to property. And when circumvention of wholesome legal inhibitions are practised on a large scale the new challenge is met by clothing the law with more effective amount and that is the rationale of the Amendment Act. The learned Judges rightly refer to the legislative proceedings	 notorious common knowledge and other relevant factors properly brought to their ken. The 'sound proof theory ' of ignoring voices from parliamentary debates	 once sanctified by British tradition	 has been replaced by the more legally realistic and socially responsible canon of listening to the legislative authors when their artifact is being interpreted We agree with the High Court when it observes : "Proceedings of legislature can be referred to for the limited purpose of ascertaining the conditions	 prevailing at 781 or about the time of the enactment in question	 which actuated the sponsor of the bill to introduce the same and the extent and urgency of the evil	 sought to be remedied. In the Statement of Objects and Reasons of the West Bengal Premises Tenancy (Second Amendment) Bill	 1969	 it is stated that it has been consider necessary that some more reliefs should be given to the tenants against eviction. It is found from the speech of the Minister at the time of introducing the Bill in the legislature	 that the problems of tenants are many : there are landlords of different kinds : there is one class original owners who are the old inhabitants of the city : these owner landlords are Dot affluent: they solely depend upon the rents received from the tenants. It has been ascertained from experience that two of the	 grounds of eviction	 namely	 of the landlords and for the purpose of building and rebuilding	 have been misused by the landlords. In the city of Calcutta and other towns	 there are millions of tenants who are left at the mercy of the landlords. In this background and after taking into account similar provisions in other States	 it has been decided that some restrictions ought to have been imposed upon transferee landlords prohibiting them from bringing ejectment suits against the tenants within three years from their purchase. On the above two grounds and for that purpose	 the said classification has been made. " The conclusion of the Court	 crystellised in the following words	 commends itself to us : "Taking an overall view of the various considerations	 the statement of	 the Minister	 the objects of the Bill	 matters of common knowledge and state of facts	 existing at the time of the legislation	 it may be well conceived that underlying policy and objects of the amended provision is to give more protection to the tenants against eviction and the classification of landlords into owner landlords and transfereelandlords is based upon a rational and intelligible differentia and we hold accordingly. " Proceeding to examine the limited attack on section 13(3A) of the basic Act read with section 13 of the Amending Act	 we have to remember die comity of constitutional instrumentalities and raise the presumption that the legislature understands and appreciates the needs of the people and is largely aware of the frontiers of and limitations upon its power. (See: The State of Bombay vs R. M. D. Chamar baguwala(1) and Shri Ram Krishna Dalmia vs Shri Justice section R. Tendolkar & Others(2). Some Courts have gone	 to the extent of holding that "there is a presumption in favour of constitutionality	 and a law will not be declared unconstitutional unless the case is so clear as to be free from doubt; and 'to doubt the constitutionality of a law is to resolve it in	 favour of its validity. "(3) Indeed	 the Legis (1) ; (2) ; (3) Constitutional law of India by H. M. Seervai p 54 vol. 1. 782 lature owes it to the Court to make like respectful presumptions. We therefore view the provision impugned through a socially constructive	 not legally captious	 microscope to discover glaring unconstitutional infirmity	 if any	 and not chase every chance possibility of speculative	 thought which may vitiate the law. Stray misfortunes when laws affecting large chunks of the community are enacted are inevitable and the respondents before us may perhaps belong to that category. Social legislation without tears	 affecting vested rights	 is impossible. Statutory construction has a benignant sensitivity and we are satisfied the High Court	 in substantially upholding the Amendment Act	 has done right	 but in striking down the retrospective portion of the section has stumbled into a specious error. It is helpful to reproduce the relevant portion of section 13 of the basic Act in its unamended state and the amendments dovetailed into it by the 1969 Act	 The so called 'retrospectivity ' of this provision has been anathematised by the respondent landlords and annulled by the High Court : "13(1) Notwithstanding anything to the contrary in any other law	 no order or decree for the recovery of possession of any premises shall be made by any Court in favour of the landlord against a tenant except on one or more of the following grounds	 namely: unamended cl. (f) : where the premises are reasonably required by the landlord either for purposes of building or rebuilding or for making thereto substantial additions or alterations or for his own occupation if he is the owner or for the occupation of any person for whose benefit the premises are held; cls. (f) and (ff) substituted therefor (f)subject to the provisions of sub section (3A)	 and section 18A	 where the premises are reasonably required by the landlord for purposes of building or re building or for making thereto substantial additions or alterations and such building or rebuilding or additions or alterations cannot he carried out without the premises being vacated	 (ff) subject to the provisions of subsection (3A)	 where the premises are reasonably required by the landlord for his own occupation if he is the owner or for the occupation of any person for whose benefit the premises are held and the landlord or such person is not in possession of any reasonably suitable accommodation	 Sub section (3A) newly introduced. 13(3A) Where a landlord has acquired his interest in the premises by transfer	 no suit for the recovery of possession of the premises on any of the grounds mentioned in clause (f) or clause (ff) of sub section (1) shall be insti 78 3 tuted by the landlord before the expiration of a period of three years from the date of his acquisition of such interest : Provided that a suit for the recovery of the possession of the premises may be instituted on the ground mentioned in clause (f) of sub section (1) before the expiration of the said period of three years if the Controller	 on the application of the landlord and after giving the tenant an opportunity of being beard	 permits	 by order	 the institution of the suit on the ground that the building or rebuilding	 or the additions or alteration	 as the case may be	 are necessary to make the premises safe for human habitation. " Once the substantive restriction super added by section 13(3A) is held valid	 we have to focus attention only on the extension of the new ban to pending proceedings. That legislative competence to enact retroactively exists is trite law and we have only to test its validity on the touchstone of articles 14 and 19 (1) (f) pressed into service before us. Law is a social science and constitutionality turns not on abstract principles or rigid legal canons but concrete realities and given conditions; for the rule of law stems from the rule of life. We emphasize this facet of sociological jurisprudence only because the High Court has struck down section 13 of the Amendment Act on surmises	 possi bilities and may be rather than on study of actualities and proof of the nature	 number and age of pending litigations caught in the net of the retrospective clause. Judges act not by hunch but on hard facts properly brought on record and sufficiently strong to rebuff the initial presumption of constitutionality of legislation. Nor is the Court a third Chamber of the House to weigh whether it should legislate retrospectively or draft the clause differently. We find no foundation for the large assumptions made by the High Court and duly repeated before us by counsel that there may be cases of ejectment instituted prior to 1956 or that a number of suits and decrees perhaps decades old will unjustly be nullified by the previous operation of the new ban. Recondite instances and casual hardships cannot deflect constitutional construction of social legislation	 if the main thrust of the statute relates to a real social evil of dimensions deserving to be antidoted by antedated legislative remedy. In the present case	 indubitably the State was faced with a new	 insidious and considerable situation of exploitation	 undermining the security of tenancy conferred by the basic Act. A large number of original landowners living in their own home could not	 under the basic Act	 claim recovery of possession	 being occupants of their own houses. Likewise	 they could not urge the ground of recovery for rebuilding	 not being financially able to invest on such a costly venture. They had to look up to modest old time rentals as the only source of return and lest the penurious tenantry desperately inhabiting little tenements be forced to pay extortionate rents the rent control law of 1956 froze the rates at the 1940 level with gentle increases as provided therein. However	 for now buildings to be constructed 784 special incentive provision was made by deeming the contract rent as fair rent	 thus ensuring a high return on building investment. The social upshot of this scheme was that the old landlords found their ownership a poor return investment	 saw a new class of wealthier investors streaming into cities and towns ready to buy the premises evict old tenants	 re let on rack rents or re build and reap a rich return. They had no buildings of their own and could prove plans to rebuild	 thus disarming the nonevictability provision of section 13 of the basic Act. The transferees could thus get decrees for eviction under the basic Act. Naturally	 transfers of buildings to this somewhat speculating class increased and the spectacle of eviction litigation ' or potential eviction proceedings was projected on the urban scene. The Legislature promptly reacted by the Amendment Act to rescue the lessees by clamping down new restrictions by way of section 13 (3A). A three year moratorium was given to the tenants from being hunted out of their homesteads by imposing a ban on institution of suits for eviction by transferee landlords. This would both disenchant speculative purchases and provide occupants time to seek alternative housing. Presumably	 these objects inspired the law makers to extend the embargo backwards to pending eviction proceedings. Quite conceivably	 the tendency to create a transferee class of real estate owners gradually gathered in volume and showed up in rashes of pending actions. When Government was alerted amending legislation was proposed. Unfortunately	 the State 's legal wing has failed to protect	 in Court the class for whose benefit the amending law was made by placing luscent social or statistical materials on these aspect . As earlier stated by us	 Government have a duty	 where social legislation to protect the weak are challenged	 to exhibit the same activism in the Halls of Court as in the Houses of Legislature. Failure in the former duty can be as bad as not promulgating the law. Not an elucidatory affidavit by the State nor even the Minister 's explanatory speech has been filed in this Court. We make these observations because of the handicaps we have faced and the little help on facts the State has given to sustain the legislation. The Calcutta High court has upheld the vires of sub section (3A) but invalidated its application to pending litigation. So the short issue is whether this projection into the past of the otherwise reasonable restriction on the right of eviction arbitrary	 irrational	 ultra vires ? If yes	 the lethal sting of articles 14 and 19(1) (f) will deaden section 13 of the Amendment Act. And the High Court has held so on 	he latter Article. The prospective validity of the restriction under articles 14 and 19(1) (f)	 the High Court thinks	 is vindicated by sound classification and sanctioned reasonably by the interest of the general public. Having regard to the policy of the legislation	 the classification of landlords into two classes of owner landlords and transferee landlords and the imposition of an embargo on the latter minacious class against bringing eviction suits within three years of purchase passes the dual tests of reasonable classification and the differentia having a rational nexus with the statutory object. Therefore	 the High Court had no hesitation and we totally concur that the provision is 78 5 impregnable. The controversy rages round giving effect to these stringent restraints newly enacted on earlier legal actions. This	 it is contended	 is a horrendous invasion of property right	; and unjust anteriority which hits innocent plaintiffs whose	 purchases were beyond three years. Before us respondents ' counsel have contended that article 14 is violated. by section 3 read with section 4 of the Amendment Act although the high Court has negatived this submission thus : "We have carefully considered the arguments advanced by the learned counsel and we are of the Opinion that the retrospective operation of sub section (3A) on pending suits and appeals does not offend Article 14 of the Constitution. " Since the argument	 dressed	 differently	 has been urged before us again we will briefly deal with it	 agreeing as we do with the High Court. Plaintiffs whose transfers are twenty years ago or two years before the Act	 are lugged together and subjected to the same ban if their suits were instituted within three years of the transfer. This blanket ban regardless of the varying periods which have elapsed after the transfers and before the Act was passed was unequal treatment or rather harshly equal subjection to restriction of plainly unequally situated transferees. There is seeming attractiveness in this presentation. But Courts are concerned not how best to hammer out equal justice but to oversee whether the classification is without rational basis unrelated to the object of the Act. That is why we are confined to check whether the reasoning on this aspect adopted by the High Court is not tenable. We may or may not disagree with the wisdom of the Legislature in the grouping adopted or hold views about fairer ways of treatment. But our powers are judicial	 not legislative and arbitrariness and irrationality are not writ large in the method of differentiation the legislature has here chosen. In the words of A. K. Mukuherji J : "In the instant case	 suits of the affected transfereelandlords may be regarded as a sub class	 within a class and	 if within the said sub class	 the suits are not differently treated	 they will not be hit by Article 14. The persons affected are transferee landlords who instituted their suits within three years of their purchase and they form a separate class and	 among the suits of that 'affected class '	 there is no discrimination. The law applied equally with respect to the pending suits with regard to this affected class. " Some hardship is bound to occur peripherally in any mode of classification and a few hard cases (we have not been shown whether many have been struck by this pattern of grouping) cannot guide the Court in upsetting legislative compartmentalisation. The next attack by the respondents is that the deprivation of the right to sue is absurdly beyond the object of the Act when applied to pending cases where the transfers took place more than three years before the Act. Were we draftsmen of legislation	 may be counsel 's submission could have had more potency. But our limited power is to 786 examine the reasonableness of the restriction	 not by substituting our personal notions but by interfering if the Legislature has gone haywire in unreasonably hamstringing transferee landlords by dismissing suits brought long before the legislative bill was in the womb of time. In an earlier case this Court observed(1) "Right at the	 threshold we must warn ourselves of the limitations of judicial power in this jurisdiction. Mr. Justice Stone of the Supreme Court of the United States has delineated these limitations in United States vs Butter ; 80 Law. Ed. 477 thus: The power of courts to declare a statute unconstitutional is subject to two guiding principles of decision which ought never to be absent from judicial consciousness. One is that courts ire concerned only with the power to enact statutes	 not with their wisdom. The other is that while unconstitutional exercise of power by the executive and legislative branches of the government is subject to judicial restraint	 the only check upon our exercise of power is our own sense of self restraint. For the removal of unwise laws from the statute books appeal lies not to the courts but to the ballot and to the processes of democratic government. " In short	 unconstitutionality and not unwisdom of a legislation is the narrow area of judicial review." The High Court has assumed that even proceedings started prior to 1956 may be affected. This	 admittedly	 is wrong as pre basic Act suits will be governed by the	 then law as provided in section 40 and the Amendment Act amends only the 1956 Act. It may also be conceded that in both the appeals before us	 thanks to Indian longevity of litigation	 more than three years from the date of transfer in favour of the plaintiff has passed and thus the spirit of the protection in that sense is fulfilled. Indeed	 counsel for the. respondents urged that the validation of the retrospective limb of the law would only drive the parties to fresh suits	 thus promoting multiplicity of suits ruinous to both sides with no social gain. There is force in this submission. Its relevance to decide	 the constitutional issue is doubtful but its influence on our ultimate solution in this case	 as will be seen later	 is undeniable. A closeup of the social milieu leading up to the enactment in 1969 of the Amendment Act is useful to identify the substantial	 mischief the law was intended to overpower. Did that evil reasonably necessitate	 for effectual implementation of purpose	 the extension of the new law to pending suits and appeals ? How many suits	 appeals and second appeals by transferees within the three year belt were pending? How long had they been so pending? Were there only stray eviction cases of long ago and was it feasible or necessary to (1) Murthy Match Works vs Asst. Collector of Central Excise	 A.T.R. 1974 8.C. 497	 503. 787 draw a line somewhere to prevent injustice to non speculative and old time buyers of buildings without impairing the limited immunity meant for tenants and intended against now realty investors ? On these facts the State has sat with folded hands and we have been thrown on our own to scan and sustain or strike down. But here arises the significance of initial presumption of constitutionality. The High Court has made short shrift of this plea thus : "There is nothing on the record to show that the mischief	 sought So be remedied by the amended legislation	 was in existence since 1956. On the other hand	 the ministerial speech	 referred to above	 rather indicates that the said mischief was of comparatively recent origin. In this context	 the application of the restriction on the omnibus scale to ill pending suits and appeals would smack of unreasonableness. " Who has the onus to place compelling facts	 except in flagrant cases of gross unreasonableness	 to establish excessiveness	 or perversity	 in the restriction imposed by the statute? Long ago in Dalmia 's Case(1) this Court held that "there is always a presumption in favour of the constitutionality of an enactment and the burden is upon him who attacks it to show that there has been a clear transgression of the constitutional principles"; and 'that it must be presumed that the legislature understands and correctly appreciates the need of its own people	 that its laws are directed to problems made manifest by experience and that its discriminations are based on adequate grounds 	 If nothing is placed on record by the challengers the verdict ordinarily goes against them. Moreover, what is the evil corrected by the Amendment Act? The influx of a transferee class of evictors of tenants and institution of litigation to eject and rack rent or re build to make larger profits. Apparently, the inflow of such suits must have been swelling slowly over the years and when the stream became a flood the Legislature rushed with an amending bill. Had it made the law merely prospective, those who bad, in numbers, already gone to Court and induced legislative attention would have escaped the inhibition. This would defeat the object and so the application of the additional ban to Pending actions could not be called unreasonable. To omit to do so would have been unreasonable folly. The question is whether those cases which were filed several years ago should have been carved out of the category of transferees hit by the Act ? Where do you draw the line ? When did the evil assume proportions ? These are best left to legislative wisdom and not court 's commonsense although there may be grievances for some innocent transferees. (1) ; , 297 propositions (b) and (c). 788 If this be the paradigm of judicial review of constitutionality, we have to ignore exceptional cases which suffer misfortune unwittingly. The law is made for the bulk of the community to produce social justice and isolated instances of unintended injury are inevitable martyrs for the common good since God Himself has failed to make perfect laws and perfect justice, Freaks have to be accepted by the victims rightly or wrongly as forensic fate: Not that it should be so but human infallibility being unattainable, easily the next best in social justice is to promote the public weal sacrificing some unmerited private hurt as unfortunate but unavoidable. It must be conceded that prima facie the two landlord respondent 's had purchased the buildings in the early sixties and three time three years or more have now passed since that date. But while considering constitutionality can we be moved by such accidental instances ? No. The substantial evil has been substantially met by a broad application of the new ban to pending proceedings. We see in the Amendment Act no violation of article 19(1) (f) read with 19(5). The same High Court, in a later case Kalyani Dutt vs Pramila Bala Dassi(1) came to the same conclusion by what it called 'independently considering the question '. We discern nothing substantially different in the analysis or approach to merit review of our result. We hold section 13 of the Amendment Act valid and repel the vice of unreasonableness discovered in both the reported rulings of the High Court. And if reasonable interpretation can avoid invalidation, it is surely preferable. Here humanist considerations, public policy and statutory purpose may provide guidelines of construction within reasonable limits. Section 13 of the Amendment Act reads: 13. Retrospective effect. The amendments made to the said Act by section 4	 7	 8 and 9 of this Act shall have effect in respect of suits including appeals which are pending at the date of commencement of this Act. " The Court is called upon 'to give effect to section 4. of this new Act. ' Section 4 introduced amendments in section 13 of the basic Act which we have set out earlier. There is no doubt that the purpose of the law is to interdict	 for a spell of three years	 institution of suits for eviction on grounds (f) and (ff) of sub section Section 13 of the Amending Act makes it expressly applicable to pending actions	 so much so the operation of the prohibition is not simply prospective as in the Kerala case cited before	 us (Nealakandhayya Fillai vs Sankaran(2). Section 13	 fairly read	 directs that the amendment made by section 4 shall have effect in respect of suits	 including appeals	 pending at the commencement of the Act. We are therefore bound to give effect to section 4 in pending actions	 regardless of isolated anomalies and individual hardships. As earlier noticed	 section 4 has two limbs. It amends section 13 of the basic Act by substituting two new clauses (f) and (ff) in place of the old clause (f) of sub section (1) of section 13 Secondly	 it forbids	 for a period of three years from the date of acquisition	 suits by new acquirers of (1) I.L.R. (2) (1961) R.L.T. 755. 789 landlord 's interest in premises	 for recovery of possession on any of the grounds mentioned in cl. (f) or cl. (ff) of sub section (1). The result of the= two mandatory provisions has to be clearly understood. For one thing although the old cl. (f) is substantially similar to the present cls. f) and (ff)	 the latter imposes more severe restrictions protecting the tenants. Much more has to be proved by the landlord now before he can get eviction than when he was called upon to under the earlier corresponding provision of the basic Act. Moreover	 the three year prohibition against institution of the suit is altogether new. It follows	 therefore	 that on the present allegations and evidence the landlord may not get a decree	 his suit having been instituted at a time when he could not have foreseen the subsequent enactment saddling him with new	 conditions. We consider that where two interpretations are possible that which validates the statute and shortens litigation should be preferred to the one which invalidates or proliferates it. We are guided by that consideration in the interpretative process. We are satisfied further that originally brought in	 is defective since it did not contain and ordinarily could not averments complying with the new cls. (f) and (ii) of sub section (1) of section 13 and we are making it effectively by construing the word 'institute ' in a natural and grammatical way. The suit is really instituted in compliance with cls. (f) and/or (ff) only when the new pleading is put in. The bigger roadblock in the way of the plaintiff is in a pending action lies in the prohibition of the institution of the suit within three years of the transfer from the landlord. Indeed	 such prohibitions are common in rent control legislation as has been noticed by the Calcutta High Court and is found even in agrarian reforms laws (vide Malaber Tenancy Act	 as amended by Act VII of 1954	 Madras). Section 13 of the Amendment Act compels the postponement of the institution of the suit (including appeal) for a period of three years from the date of the transfer. In both the cases before us	 the suits were instituted within the prohibited period of three years. The argument therefore is that the suits must be straightaway dismissed	 the institution being invalid. We do not think that this consequence is inevitable. 'To institute	 is 'to begin or commence '	 in plain English. The question then is whether the suit can be said to begin on the date it was filed in 1961 or 1964 as the case may be. Here we have to notice a certain nice but real facet of sub section The prohibition clamped down by sub section (3A)	 carefully read	 is on suits for recovery of possession by transferee landlords 'on any of the grounds mentioned in cl. (f) or cl. (ff) of subs.(1) '. Obviously the suits with which we are concerned are not for recovery on grounds contained in cis. (f) and (ff). They were based on the repealed cl. (f) of section 13 of the basic Act. Strictly speaking	 sub section (3A) brought in by section 4 of the Amending Act applies only if (a) the suit is by a transferee landlord; b) it is for recovery of possession of premises and (c) the ground for recovery is what is mentioned in cl. (f) and cl. (ff) of sub section Undoubtedly the third condition is not fulfilled and there fore sub section (3A) is not attracted. This does not mean that the suit 790 can be proceeded with and decree for recovery passed	 because section 13 of the basic Act contains a broad ban	 on eviction in the following words : "13(1) Notwithstanding anything to the contrary in any other law	 no order or decree for the recovery of possession of any premises	 shall be made by any Court in favour of the landlord against a tenant except on one or more of the following grounds	 namely: (emphasis	 ours) Since the new cls. (f) and (ff) are included by the Amendment Act in section 13 of the basic Act and since the suits we are concerned with	 as they now stand	 do not seek eviction on those grounds they will have to be dismissed on account of the omnibus inhibition on recovery of possession contained in section 13 itself. A just resolution of this complex situation was put by us to counsel on both sides and the learned Advocate representing the State readily agreed that the policy of the legislation and the conditions in the Amendment Act would be fulfilled if the interpretation we proposed were to be accepted. We are satisfied that as far as possible courts must avoid multiplicity of litigation. Any interpretation of a statute which will obviate purposeless proliferation of litigation	 without whittling down the effectiveness of the protection for the parties sought to be helped by the legislation	 should be preferred to any literal	 pendantic	 legalistic or technically correct alternative. On this footing we are prepared to interpret section 13 of the Amendment Act and 	give effect to section 4 of that Act. How do we work it out ? We do it by directing the plaintiffs in the two cases to file fresh pleadings setting out their grounds under cls. (f) and/or (ff)_ of sub s.(1) if they so wish. On such pleading being filed we may legitimately bold that the transferee landlord institutes his suit on grounds mentioned in cls. (f) or (ff) of sub section (1) on that '.ate. It is only when he puts in such a pleading setting out the specific ground covered by sub section (3A) of section 13 that we can say he	 has begun or instituted a suit for the recovery of possession of the premises on that ground. Institution of a suit earlier has to be ignored since that was not based on grounds covered by cls. (f) and/or (ff) and is not attracted by sub section (3A). He begins proceedings on these new grounds only when he puts in his pleading setting out these_grounds. In spirit and in letter he institutes his suit for recovery on the new grounds only on the date on which he puts in his new pleading. We cannot be ritualistic in insisting that a return of the plaint and a representation thereof incorpo rating amendments is the sacred requirement of the law. On the other hand	 social justice and the substance of the matter find fulfilment when the fresh pleadings are put in	 subject of course to the three year interval between the transfer and the filing of the additional pleading. Section 13 of the Amendment Act speaks of suits including appeals. It thus follows that these fresh pleadings can be put in by the plaintiff either in the suit	 if that is pending. or in appeal or second appeal	 if that is pending. Thereupon	 the opposite party. tenant	 will be given fin opportunity to file his written statement and the Court 'Will dispose of it after giving both sides the right to lead 791 additional evidence. It may certainly	 be open to the appellate Court either to take evidence directly or to call for a finding. Expeditious disposal of belated litigation will undoubtedly be a consideration with the court in exercising this discretion. The proviso to sub section (3A) can also be complied with if the plaintiff gets the permission of the Rent Controller in the manner laid down therein before filing his fresh pleading. We	 are conscious that to shorten litigation we are straining language to the little extent of interpreting the expression 'institution of the suit ' as amounting to filing of fresh pleading. By this construction we do no violence to language but	 on the other hand	 promote public justice and social gain	 without in the least imperiling the protection conferred by the Amendment Act. Ruinous protraction of litigation	 whoever may temporarily seem to benefit by delay	 bankrupts both in the end and inflicits wounds on society by sterile misuse of money. Tenant passengers who prolong their expensive flight on the litigation rocket	 are buying tickets for financial crash	 drugged though they be by the seeming blessings of law 's delays. Courts	 by interpreting the expression 'institution of suits ' cannot authorize reincarnation	 all over again	 of litigation for eviction. We save the tenant by applying it to pending cases and save him also from litigative waste. This consideration is itself germane	 to the larger concept of justice which it is the duty of Courts to promote. Law finds its finest hour when it speaks to justice on fair terms. In the present case our interpretative endeavour has been imbued with this spirit. In the process of interpretation where alternatives are possible ' the man in the law influences the law in the man may be and the construction on sections 4 and 13 of the Amendment Act herein adopted	 we admit	 appeals to us as more	 humane. The calculus of statutory construction relating to complex problems of the community cannot be hide bound by orthodox text book canons. An obiter	 maybe. More buildings is the real solution for dwelling shortage; freezing scarcer accommodation relieves for a little while. Tiger balm is no serious cure for brain turnover We make no more comments on the need for dynamic housing policies beyond statutory palliatives. These belong to legislative 'wisdom ' and administrative 	activism ' and not to judicial 'constitutionalism '. It was noticed in the course of arguments that a later Amending Act of 1970 purporting to give relief to tenants against whom decrees for eviction bad been passed but dispossession had not ensued	 had been put on the statute book. It is surprising that counsel on either side did not choose to address us any arguments on the basis of those provisions. We therefore do not go into the impact of that Act on situations where eviction has been ordered by Courts. We therefore allow the appeals with costs but direct the High Court to dispose of the cases in the light of the directions and obser 792 vations we have made. It will be open to the	 Court seised of the matter to direct	 in its discretion	 award of costs to be incurred hereafter. GOSWAMI	 J.Civil Appeal No. 1304 of 1973 is by certificate granted by the Calcutta Hi Court and Civil Appeal No. 2063 of 1973 is by Special Leave of this Court. The first one arises out of Letters Patent Appeal No. 14 of 1969 of the Calcutta High Court dismissed on February 3	 1972	 relying upon its earlier decision in Kalyani Dutt vs Pramila Bala Dassi since reported in I.L.R. (1972) 2 Calcutta 660. A preliminary question had arisen in connection with the aforesaid Letters Patent Appeal along with three other appeals at an earlier stage with regard to the constitutionality of section 13(3A) of the West Bengal Premises Tenancy (Second Amendment) Act	 1969 (briefly the Amendment Act). A Division Bench repelled the contention of the appellants in decision which has since been reported in A.I.R. (1971) Calcutta 331 (Sailendra Nath Ghosal & Ors. vs Sm. Ena Dutt & Others). The Division Bench had held that sub section (3A) of section 13 in so far as it was retrospective in operation was ultra vires Article 19(1) (f) of the Constitution on the ground of unreasonableness. Since	 however	 the Letters Patent Appeal was not completely disposed of	 the bar of sub section (3A) was this time pleaded asserting that Article 19 was not at all attracted to the present case on the ground that the right of reversion of the landlord	 namely	 the right to recover possession of the property from the tenant	 is not a right of property which is a condition precedent to the application of Article 19(1) (f) and consequently	 the question as to the infringement of fundamental right did not at all rise and that there could not be	 any scope for holding that the provision of sub section (3A) offended against Article 19(1)(f). This second contention which was allowed to be raised by the Letters Patent Bench was also repelled following its earlier decision in Kalyani Dults case (supra) disposed of on September 7	 1971. Civil Appeal No. 2063 of 1973 arises out of the decision of the High Court in Second Appeal No. 1193 of 1972 disposed of on 25th July	 1973 relying upon Sailendra Nath Ghosal 's case (supra) which is the subject matter of appeal in Civil Appeal No. 1304 of 1973. The history of tortuous litigation in both the appeals may also be noticed. In Civil Appeal No 1304 of 1973 the plaintiff (respondent herein) purchased the premises in suit on February 16	 1961. She instituted Title Suit No. 480 of 1961 in the court of Munsif of Sealdah	 District 24 Pargana	 for ejectment of the defendant	 on July 24	 1961. The suit was decreed by the Munsif on July 21	 1964	 but was dismissed by the lower appellate court on May 17	 1965. On second appeal at the instance of the plaintiff	 the High Court framed an additional issue and remanded the suit to ram a finding on the same. On receipt of the finding of the court below	 the learned single Judge of the High Court	 dismissed the second appeal and granted 793 leave to a Letters Patent Appeal. That appeal was dismissed on February 3	 1972. The High Court granted certificate to appeal against that decision to this Court on May 24	 1973	 referring to the earlier certificate granted by that Court in Kalyani Dutt 's case (supra). That is how Civil Appeal No. 1304 of 1973 is now before us. The facts in Civil Appeal No. 2063 of 1973 are these. The property in suit was purchased by the plaintiff (respondent herein) on February 7	 1964 and the eviction suit No. 76 of 1966 was instituted in February 1965. The suit was dismissed by the Trial Court on October 11	 1966. On appeal by the plaintiff	 the Additional District Judge allowed the appeal on June 8	 1967	 and remanded the suit for disposal after taking additional evidence. The Munsif thereafter decreed the plaintiff 's suit on December 23	 1968. On appeal by the defendant the Additional District Judge allowed the same and dismissed the suit on April 8	 1969. On plaintiff 's appeal to the High Court in Second Appeal No. 968 of 1969	 the High Court allowed the same on April 3	 1971 and remanded the suit to the Munsif for retrial. The Munsif again dismissed the plaintiff 's suit on September 13	 1971. On appeal by the plaintiff the Additional District Judge allowed the same and decreed the suit on April 29	 1972. The High Court on appeal by the defendant dismissed the second Appeal on July 25	 1973	 relying upon Salindra Nath Ghosal 's case (supra) disposed of on January 28	 1971. The defendant then obtained special leave. Thus the life of litigation in Civil Appeal No. 1304 of 1973 is now in the fourteenth year after purchase of the premises by the plaintiff six months earlier. The second one is a decade old; the property having been purchased about a year earlier. Both the appeals were argued together and will be governed by this common judgment. The suits in both the appeals are by what has come to be known as transferee landlords. They have instituted suits in one case within six months of the purchase in 1961 and in the other within one year of the purchase in 1965. During the long pendency of the litigation the West Bengal Premises Tenancy (Second Amendment) Act was passed which came into force on November 14	 1969. and section 4	 inter alia	 was made applicable to pending suits including appeals. It amended the West Bengal Premises Tenancy Act	 1956 (West Bengal Act XII of 1956) (briefly the Original Act). Section 4 of the Amendment Act introduced the following changes in section 13 of Section 13(1) (f) of the Original Act stood as follows the Original Act : "13(1) Notwithstanding anything to the contrary in any other law	 no order or decree for the recovery of possession of any premises %hall be made by any Court in favour of the landlord against a tenant except on one or more of the following grounds	 namely (f)Where the premises are reasonably required by the landlord either for purposes of building or rebuilding; or 4 L346Sup. CI/75 794 for making thereto substantial additions or alterations or for his own occupation if he is the owner or for the occupation of any person for whose benefit the premises are held". After the amendment of section 13 by section 4 of the Amendment Act clause (f) was split up into two clauses (f) and (ff) which read as under : "(f) Subject to the provisions of	sub section (3A) and section 18A	 where the premises are reasonably required by the landlord for purposes of building or rebuilding or for making thereto substantial additions or alterations	 and such building or re building	 or additions or alterations. cannot be carried out Without the premises being vacated; (ff) Subject to the provisions of sub section (3A)	 where the premises are reasonably required by the landlord for his own occupation if he is the owner or for the occupation of any person for whose benefit the premises are held and the landlord or such person is not in possession of any reasonably suitable accommodation". In addition	 section 4 of the Amendment Act introduced a new subsection (3A) which reads as follows : "Where a landlord has acquired his interest in the premises by transfer	 no suit for the recovery of possession of the premises on any of the grounds mentioned in clause (f) or clause (ff) of sub section (1) shall be instituted by the landlord before the expiration of a period of three years from the date of his acquisition of such interest; Provided that a suit for the recovery of the possession of the premises may be instituted on the ground mentioned in clause (f) of sub section (1) before the expiration of the said period of three years if the Controller on the application of landlord and after giving the tenant an opportunity of being heard	 permits	 by order	 the institution of the suit on the ground that the building or re building or the additions	 or alterations	 as the case may be	 are necessary to make the premises safe for human habitation". It should be noted that the grounds for ejectment in the earlier sub section (f) 	ire the same as the new grounds in clauses (f) and (ff) except for some additional restrictions. The common grounds for eviction are	 broadly speaking	 reasonable requirement for the Purpose of building or rebuilding	 etc. [sub clause (f)] and reasonable requirement for occupation by the landlord	 etc. [sub clause (ff)]. There is	 there fore	 no particular significance to the mention of " grounds" in clause (f) or clause (ff) of subsection (1) in subsection (3A). 	Section 13 of the Amendment Act which is the bone of contention grants retrospectivity to section 4 of the Amendment Act and	 therefore	 necessarily to sub section (3A) and section 13(1)(f)(ff). The grievance centres round retrospectivity of sub section (3A) and 795 section 13(1)(f) and (ff) made applicable by force of section 13 of the Amendment Act to suits and appeals pending on the commencement of the Act. It may be in order first to deal with the question of retrospectivily of sub section (3A) which is the principal ground of attack in these appeals. Section 13 of the Amendment Act provides that. effect should be given to section 4 of the Amendment Act in pending suits including appeal on the date of the commencement of the Act. The suits of the particular category by transferee landlords	 therefore	 could be pending on commencement of the Amendment Act and these may have been instituted several years prior to the Amendment Act. There may also be appeals pending in different appellate courts against decrees in such suits. The appeals necessarily have to be understood as appeals arising out of suits instituted within the three years ' ban. The tenants are now permitted to take objection on the score of contravention of section 13(3A)	 before the courts either in a pending suit or in a pending appeal against decrees in such suits and the point for consideration then would be whether such a suit was instituted within three years ' ban and the appeal was pending against such a banned suit. When section 13 of the Amendment Act provides that section 4 therein has to be given effect in pending suits including appeals	 effect has to be given by the courts. Now how will effect be given to section 13(3A) ? Retrospectivity to be given under section 13 of the Amendment Act to section 4 broadly requires compliance as follows (1) that no suit for eviction by a transferee landlord shall be instituted within three years of his acquisition of the premises; (2) if eviction is sought on the ground under section 13(1)(f) of the Amendment Act	 an additional restriction is put	 namely	 that "such building or rebuilding or additions or alterations cannot be carried out without the premises being vacated"; (3) if eviction is sought on the ground under section 13(1)(ff)	 a further restriction is put upon the right of the landlord to evict	 viz.	 that "the landlord or such person is not in possession of any reasonably suitable accommodation". Under proviso to section 13(3A) a transferee landlord can	 however	 institute a suit within three years ' ban provided he obtains prior permission from me Controller who on an application by the landlord and after hearing the parties may decide whether permission should be given or not. Prime facie	 a suit which had already been instituted prior to the Amendment Act would not come within the mischief of section 13(3A) since this sub section	 in terms	 prohibits only institution of suits and does not provide for dismissal of suits already instituted. Similarly while there is a relaxation in favour of a transferee landlord under the proviso to obtain permission from the Controller this bene fit is out of the way even in a genuine case where the suit had already 796 been instituted within three years of purchase and the same or an appeal therefrom is now pending after the passing of the Amendment Act. In this regard also it appears sub section (3A) is not intended to be attracted to suits which were already instituted prior to the Amendment Act. But as will be seen hereafter the above position is altered by the express provision of section 13 of the Amendment Act whereby it is intended that the court should give retrospectivity	 inter alia	 to section 4 of the Amendment Act. On the terms of only section 13 (3A) it is difficult to hold that it would bring old sections within the mischief of section 13 (3A) which imposes a ban expressly on institution of suits within three years of the acquisition of ownership of the premises subject to the relaxation contained in the proviso thereto. This being the correct interpretation of sub section (3A)	 taken by itself	 what is the effect of section 13 of the Amendment Act upon this provision? Section 13 of the Amendment Act in seeking to give retrospective effect to sub section (3A) does exactly what sub section (3A) by itself contra indicates. The first part of section 13(3A) which provides for a ban against institution of suits for eviction within three years of acquisition of the premises must be given effect to under section 13 of the Amendment Act in pending suits and in pending appeals arising out of the decrees passed in such suits provided the former had been instituted within the period of the ban. If	 therefore	 after the Amendment Act it is found in a pending suit or in a pending appeal that the particular suit was instituted within the three years ' ban the same will have to be dismissed and only in that way the court will be able to give effect to sub section (3A). With regard to the proviso of subsection (3A)	 when the ground of eviction is relatable to section 13(1)(f) of the Amendment Act the court will have to dismiss the suit in absence of the requisite permission. That being the practical result of restrospectivity given to subsection (3A)	 is that sub section	 in so far as it is retrospective	 violative of Article 19(1)(f) of the Constitution? That takes us to the object and purpose of the Amendment Act. The Statement of Objects and Reasons as quoted in Kalyani Dutt 's case (supra) is as follows "It has been considered necessary that some more relief should be given to the tenants against eviction	 that the necessity of tender of rent to the landlord every time the rent is deposited with the Controller during a continuous period should be dispensed with	 that the interests of the residents of hotels and lodging houses should be safeguarded and that the penalties for contravention of some of the provisions of the West Bengal Premises Tenancy Act	 1956	 should be made more stringent". In the earlier judgment of the High Court which is also the subject matter of Civil Appeal No. 1304 of 1973 the High Court referred to the statement of the Minister at the time of piloting of the Bill in the following words: 797 "It is found from the speech of the Minister at the time of introducing the Bill in the legislature	 that the problems of tenants are many: there is one class original owners who are the old inhabitants of the city; these owner landlords are not affluent; they solely depend upon the rents received from the tenants. It has been ascertained from experience that two of the grounds of eviction	 namely	 requirement of the premises for own use of the landlords and for the purpose of building and re building	 have been misused by the landlords. In the city of Calcutta and other towns	 there are millions of tenants who are left at the mercy of the landlords. In this background and after taking into account similar provisions in other States	 it has been decided that some restrictions ought to have been imposed upon transferee landlords prohibiting them from bringing ejectment suits against the tenants within three years from their purchase". The High Court also observed further that "there is nothing on the record to show that the mischief	 sought to be remedied by the amended legislation	 was in existence since 1956. On the other hand	 the ministerial speech	 referred to above	 rather indicates that the said mischief was of comparatively recent origin". Again in Kalyani Dutt 's case (supra) the High Court in para 27 observed that "such suits are not many and at the same time most of them are pending for more than ten years". The materials relied upon by the High Court stand uncontradicted by any affidavit before US. On the above materials it is safe to hold that the main object of the Amendment Actis to counteract the "recent" mischief of circumvention of theprovisions of the original Act in order to evict tenants on even bona fide requirements specified under the law of device of transfer of premises held under the occupation of tenants. Although the Amendment Act has not completely barred institutions of suits by transferee landlords postponement of litigation for a period of three years from acquisition of the premises was provided for under subsection (3A). This had a twofold purpose	 namely	 to enable tenants a reasonable respite to arrange their affairs and also to discourage speculative acquisitions with an ulterior motive. This salutary pro vision for the general body of tenants cannot be called unreasonable. But the question is whether by applying the provision to pending suits and appeals has that object been achieved in the interest of the general body of tenants which would certainly constitute the general public within the meaning of clause 5 of Article 19? From the fact 	; and circumstances extra fed above from the two judgments of the High Court. it is not possible to bold that the interest of the general body of tenants would be served by application of sub section (3A) to pending suits and appeals. If the mischief was of "recent" origin	 there is no reason to overshoot the mark and outstretch the long rope of the law beyond the 798 requirements of the situation. It is clear that in trying to include old actions that may be surviving in courts	 per chance	 because of laws ' proverbial delay	 section 13 of the Amendment Act has gone far in excess of the actual needs of the time and problems and the provisions thereof cannot be said to impose a reasonable restriction on the right of the transferee landlords	 albeit a well defined class	 amongst tile landlords	 to hold and enjoy their property in the interest of the general public. Such transferee landlords with pending old sections in suits or in appeals are	 as observed by the High Court	 not likely to be of a large number and necessarily so the tenants of such a sub sec class. It is not in the general interest of the large body of tenants to impose such restrictions on a few transfree landlords of this sub class subject to unbearable delay in litigation	 understandably not on their own account. If relief in the shape of postponement of a landlord 's suit were the object of sub section (3A) in giving retrospectivity to it	 the law did not take count of the inevitable long delay that takes place in pending litigation of this type as a result of man made laws of procedure in courts such as has even been clearly demonstrated by the cases at hand. The law that misses its object cannot justify its existence. Besides	 it will be a sterile relief if tenants have to face a fresh summons next day. Hard cases will be on both sides of the line. law contemplates in terms of generality and is not intended to hit a few individuals by making invidious distinction. Article 19 of the Constitution confers protection of rights specified therein belonging to all citizens. Any individual citizen may complain of encroachment of his rights and freedom guaranteed under the Article. Law 's encroachment upon such rights and freedom of citizens can survive challenge if it passes the tests laid down in the six saving clauses of Article 19. Coming now to article 19(1)(f)	 with which we are concerned in these appeals	 the said provision confers upon each individual citizen the right to acquire	 hold and dispose of property	 This right is subject to clause (5) which we may read so far as material for our purpose: "Nothing in sub clauses (d)	 (e) and (f) of the said clause shall . prevent the State from making any law imposing reasonable restrictions on the exercise of any of the rights conferred by the said sub clauses . in the interests of the general public. . Even a single citizen may complain against violation of his fundamental rights under Article 19 (1) (f) and his vindication of his right may be defeated only if the impugned infringement brought upon by the law can be considered as a reasonable restriction and the 	aid restriction is also in the interests of the general public. It is manifest	 therefore	 under the Constitution. that an individual 's right will have to yield to the common weal of the general community. That general community may be in broad segments	 but even then must form a class as a whole. A few individuals cannot take the place of a class and for the matter of that the general public In the present case the particular relief contemplated by the Amendment Act is in favour 799 of tenants in general and the restriction under sub section (3A) must 	be viewed in that context. It cannot be said that the legislature in applying sub section (3A) restrospectively has achieved that avowed object at all. The matter would have been different it	 in view of any prevailing conditions	 a reasonable date for giving retrospective effect were fixed under the law in the light of the known mischief. In its. absence	 applicability of the blanket ban to pending suits and appeals cannot be said to be a reasonable restriction in the interests of the general public. It may help a few tenants in litigation but will prejudice the right of transferee landlords locked up in old and costly litigation. The gain of the few as opposed to the general public cannot be the touchstone for justifying reasonableness of the restriction imposed on the rights of the transferee landlords in applying subsection (3A) to pending suits and appeals. In the social combat between the interests of a few and the general welfare of the community the latter is the clinching factor to be reckoned and hard cases of a few individuals cannot be assigned a higher place and status than they deserve to the detriment of the fundamental rights of even a single individual. Therefore	 the retrospectivity so far as sub section (3A) is concerned with regard to institution of suits made applicable to pending suits and. appeals is clearly very wide of a reasonable mark and is	 thus	 an imposition of an unreasonable restriction on the rights of the transferee landlords in pending suits which had been instituted prior to the Amendment Act and in appeals arising therefrom and it is not saved by the protective clause (5) of Article 19 of the Constitution. Sub section (3A) so far as it is retrospective and as such applicable to pending suits including appeal is ultra vires Article 19 (1)(f) of the Constitution. The provision is valid only prospectively. So far as the retrospectivity of section 13(1)(f) and (ff)	 the position is entirely different. Clearly further reliefs have been sought to be given to the tenants as a class by these provisions in the Amendment Act. These further reliefs are in the general interests of tenants and can be applied without any difficulty to pending suits including appears. There is nothing unreasonable about such a retrospectivity in applying these provisions for the general welfare of tenants in securing for them a safe and sure tenure as far as practicable untrammelled by inconvenient litigation. It is well established that the legislature in enacting laws can legislate prospectively as well as retrospectively. Section 13(1)(f) and (ff) are	 therefore	 not ultra vires Article 19(1) (f) of the Constitution. With regard to another contention of the appellants that the right of tile landlords that is affected by sub section (3A) is only a mere right to sue and at best a right of reversion and hence it is not a right to property under Article 19(1)(f) of the Constitution	 it is sufficient to state that the question is covered by two decisions of this Court in The Commissioner	 Hindu Religious Endowments	 Madras vs Sri Lakshmindra Thirtha Swamiar of Sri Shirur Mutt(1) and Swami (1) ; 800 Motor Transport (P) Limited and Another vs Sri Sankaraswamigal Butt and Another(1). The right to own and hold property in order to make an effective right under the Constitution must include tine right to possession of the property including the right to evict tenants in accordance with law. The submission is	 therefore	 without any force. The position	 therefore	 is that in a pending suit or even in a pending appeal a landlord may be given an opportunity to adduce evidence to establish such of the new requirements in 13(1) (f) or (ff) as are relevant to the proceedings. In that case the tenant will have also an opportunity to produce evidence in rebuttal. If the matter arises in a pending suit	 it will be disposed of by the trial court. If	 however	 the matter arises in appeal	 it will be open to the appellate court	 in order to shorten the life of litigation	 to remand the matter to the appropriate court to return a finding on such additional issues as may be framed to meet the requirements of (f) and/or (ff)	 as the case may be	 under order 41	 rule 25	 Civil Procedure Code. In the result these appeals are partly allowed. The judgment of the High Court with regard to invalidity of sub section (3A) so far as it is retrospective and applicable to pending suits and appeals is upheld. The orders dismissing the appeals are	 however	 set aside and the appeals are remanded to the High Court for disposal in the light	 of the observations with reference to section 13(1)(f) and/or (f) whichever is applicable. The landlords may now be given by the High Court an opportunity	 if they so wish	 to adduce evidence with regard to such further requirements under (f) and/or (ff) as may be applicable and the High Court will call for a finding from the appropriate court in that behalf and thereafter dispose of the appeals on merits. Since success is shared	 there will be no orders as to costs in these appeals. ORDER In accordance with the majority judgment	 the appeals are allowed with costs; the cases are remanded to the High Court	 and the High Court is directed to dispose of the case in the light of the directions and observations made in the majority judgment. It will be open to the Court seised of the matter to direct	 in its discretion	 amount of costs to be incurred hereafter. P.B.R. (1) [1963] Supp. 1 S.C.R. 282.

Section 13(1)(f) of the West Bengal Premises Tenancy Act	 1956 Act XII of 1956) enacted that no order or decree for the recovery of possession of any premises shall be made by any court in favour of the landlord against the tenants except among others	 on the ground that the premises are reasonably required by the landlord either for the purpose of building or rebuilding or for making thereto substantial additions or alterations or for his own occupation if he is the owner or for the occupation of any person for whose benefit the premises are held. Section 13(4) of the Act provides that where a landlord requires the premises on any of the grounds mentioned in cl. (1)(f) and the Court is of opinion that such requirement may be substantially satisfied by ejecting the tenant from a part only of the premises the Court shall pass a decree accordingly. In 1969 the Act was amended by West Bengal Premises Tenancy (Second Amendment) Act. Section 13 of the original Act was amended by introducing sub section (3A) in it. This sub section prohibits institution of a suit for ejectment of a tenant by a landlord who has purchased the premises for his own use within three years of the purchase. The Amending Act also enacted that the said Act shall apply to suits and appeals	 which are pending at the date of the commencement of the Act. The respondent purchased the suit premises in which the appellant was a tenant and instituted a suit for ejectment of the tenant under s.13(1)(f) of the original Act. The suit was decreed by the lower court and affirmed by the lower appellate court. A single Judge of the High Court dismissed the appeal. When the Letters Patent Appeal was pending before the High Court	 the Amending Act of 1969 was passed	 whereupon	 the tenant appellant invoked the provisions of the new sub sec. (3A) and contended that since the landlord had instituted a suit the ejectment within three years of the purchase	 the suit should be dismissed. The High Court held that s.3A was valid prospectively but that the restriction imposed by the sub section. giving it retrospective effect	 was violative of article 1(1) (f) of the Constitution. Per Beg and Krishna Iyer	 JJ: Allowing the appeals and remitting the case to the High Court	 HELD : (1) (a) There is no violation of article 19(1) (f) read with article 19(5) of the Constitution in the Amending Act	 and s.13 of the original Act	 as amended is valid. The evil corrected by the Amendment Act is to stop the influx of a transferee class of evictors of tenants and institution of litigation to eject and rack rent or re build to make large profits. Apparently the inflow of such suits must have been swelling slowly over the years and when the stream became a flood the Legislature rushed with an amending bill. Had it made the law merely prospective	 those who had	 in numbers	 already gone to Court and induced legislative attention would have escaped the inhibition. This would defeat the object and so the application of the additional ban to Pending actions could not be called unreasonable. There is no foundation for the assumptions made by the High Court that there may be cases of ejectment instituted prior to 1956 or that a number of suits and decrees	 perhaps decades old. will unjustly be nullified by the previous operation of the new ban. Recondite instances and casual hardships cannot deflect constitutional construction of social legislation	 775 if the main thrust of the statute relates to a real social evil of dimensions deserving to be antidoted by antedated legislative remedy. Questions such as whether those cases which were filed several years ago should have been carved out of the category of transferees hit by the Act	 and at what point of time the evil assumed proportions were best left to legislative wisdom and not to courts commonsense. [788C D; 787F G; 783F; 787H] In the instant case the two landlord respondents had purchased the buildings in the early sixties	 but while considering the constitutionality the Court would not be moved by such accidental instances. The substantial evil has been substantially met by a broad application of the new ban to pending proceedings. [788C] Section 13. fairly read	 directs that the amendment made by section 4 shall have effect in respect of suits	 including appeals	 pending at the commencement of the Act. The Court is	 therefore	 bound to give effect to section 4 in pending actions regardless of isolated anomalies and individual hardships. [788G] (b)Where two interpretations are possible that which validates the statute and shortens litigation should be preferred to the one which invalidates or proliferates it. Although the old cl. (f) is substantially similar to the present cls.(f) and (ff) the latter imposes more severe restrictions protecting the tenants. Much more has to be proved by the landlord now before he can get eviction than when he was called upon to under the earlier corresponding provision of the basic Act. Moreover	 the three year prohibition against institution of the suit is altogether new. It follows	 therefore	 that on the present allegation and evidence the landlord may not get a decree	 his suit having been instituted at a; time when he could not have foreseen the subsequent enactment saddling him with new conditions. [789C; 789B] Though therefore	 the suit	 as originally brought in	 would be defective since it did not and could not contain the averments complying with the new cls. (f) and (ff) of section 13(1) it is made effective by construing the term 'institute ' in a natural and grammatical way. [789D] (c) 'To institute is 'to begin or commence '. The prohibition clamped down by sub section (3A)	 carefully read	 is on suits for recovery of possession by transferee landlords on any of the grounds mentioned in cl. (f) Qr cl. (ff) of sub section (1). [789G] In the instant case the suits were not for recovery on grounds contained in clauses (f) and (ff). They were based on the repealed cl.(f) of s.13 of the basic Act. Strictly speaking sub section (3A) brought in by section 4 of the Amending Act applies only if (a) the suit is by a transferee landlord; (b) it is for recovery of possession of premises; and (c) the ground for recovery is what is mentioned in cls. (f) and (ff) of sub section (1). Undoubtedly the third condition is not fulfilled and therefore sub section (3A) is not attracted. [789H] (d)But since the new cls.(f) and (ff) were included by the Amendment Act in s.13 of the basic Act and since the suits did not seek eviction on those grounds they will have to be dismissed on account of the omnibus inhibition on recovery of possession contained in section 13 itself. [790C] Per Goswami	 J : (1)(a) In trying to include old actions that may be surviving in courts because of laws ' proverbial delay section 13 of the Amended Act has gone far in excess of the actual needs of the time and problems and the provisions therefore cannot be said to impose a reasonable restriction on the right of the transferee landlords	 albeit a well defined class amongst the landlords	 to hold and enjoy their property in the interest of the general public. Such transferee landlords with pending old actions in suits or in appeals are not likely to be of a large number. The imposition of such restrictions on a few transferee landlords cannot be in the general interests of the large body of tenants. If relief in the shape of postponement of the landlord 's suit were the object of sub section (3A) in giving retrospectivity to it. the law did not take count of the inevitable long 776 delay that takes place in pending litigation as a result of man made laws of procedure in courts such as have been clearly demonstrated by the cases at hand. The lawthat misses its object cannot justify its existence. Besides it will be a sterilerelief if tenants have to face a fresh summons next days. [798A C] (b)Under the Constitution an individual 's right will have to yield to the commonweal of the general community	 That general community may be in broad segments but even then must form a class as a whole. A few individuals cannot take the Place of a class and for the matter of that the general public. [798H] In the present case the relief contemplated by the Amendment Act is in favour of tenants in general and the restriction under sub section (3A) must be viewed in that context. It cannot be said that the legislature in applying sub section (3A) retrospectively has achieved that avowed object at all. The applicability of the blanket ban to pending suits and appeals cannot be said to be a reasonable restriction in 	he interest of general public. [799A B] (c)Sub section (3A) so far as it is retrospective and as such applicable to pending suits including appeals is ultra vires article 19(1) (f) of the Constitution. The provision is valid only prospectively. The retrospectivity so far as subsection (3A) in concerned with regard to institution of suits made applicable to pending suits and appeals is clearly very wide of a reasonable mark and is an imposition of an unreasonable restriction on the right of the transferee landlords in pending suits which had been instituted prior to the amendment Act and in appeals arising therefrom and it is not saved by the protective clause (5) of article 19 of the Constitution. [799D E] (2)On the terms of only section 13 (3A) it is difficult to hold that it would bring old actions within the mischief of section 13(3A) which imposes a ban expressly on institution of suits within three years of the acquisition of ownership of the premises subject to the relaxation contained in the proviso thereto. [796B C] (3)Section 13(1)(f) and (ff) are not ultra vires of article 19(1)(f) of the Constitution. Further reliefs have been sought to be given to the tenants as a class by these provisions in the Amendment Act. These further reliefs are in the general interests of tenants and can be applied without any difficulty	 to pending suits including appeals. There is nothing unreasonable about such a retrospectivity in applying these provisions for the general welfare of tenants in securing for them asafe and sure tenure as far as practicable untrammelled by inconvenient litigation.[799F G] Arguments for theappellants In C.A. 2063/73 by P. C. Chatterjee There is no vestedright to eject on determination of the tenancy but it is conditioned by section 13	 Cl. (a) to (k) and therefore right to eject is not vested in the landlord until a decree is passed. Upto that stage it is contingent depen ding on the satisfaction of cl. (a) to (k) of s.13. If there is no vested property right	 no question of article 19(1)(f) of the Constitution will arise. By denying the right to eject for three years from the date of purchase the right to property is not restricted or burdened. The approach of the High Court of separately treating prospectivity and retrospectivity is not correct. The correct approach adopted by this Court is that in considering the reasonableness of any provision retrospectivity of the law is a factor to be considered. Retrospective operation is not bad because it covers a period of 10 years or so. For respondent (In C.A. 1304 of 1973.) The object of the new sub section (3A) being to give protection to tenants for a limited period of three years from the date of purchase of the premises by the landlord	 by giving retrospective effect to ' the said sub section the period limited by the subsection cannot be enlarged. Therefore	 s.13 of the Amending Act which gives retrospective effect to the said sub section (3A) should be construed in a manner so as to keep the effect of retrospectively within the period 777 limited by the said new sub section 3A. Sections 4 and 13 of the Amending Act have to be construed harmoniously keeping the object of the Act in view and in doing that if the court has to supply some words to make the meaning clear	 it should prefer the construction which is more in consonance with reason and justice. at 745. The language of sub section 3A and the object and reason for introduction of the said sub section make it clear that Only Prospective effect could be given to the sub section and in any case its effect cannot go beyond three years of purchase of the premises by the landlord. If	 s.13 of the Amending Act means that section 4 of the Amending Act applies to all pending suits including appeals filed by a transferee landlord after the principal Act came into force	 then it is clearly violative of art 19(1)(f) of the Constitution. The High Court therefore	 rightly struck down s.13 giving retrospective effect to section 4 of the 	 Act. Further no law can impose restrictions retrospectively on fundamental rights. Arguments for the respondent in C.A. No. 2063 of 1973. The impugned section cannot be so interpreted as to give it retrospective effect so as to bring within its mischief all suits and proceedings including appeals which may be pending since the enforcement of the Act. This Court can depart from the general rule to apply the law as it is on the date of institution of the suit and apply the law as on the date when the appeal comes up for disposal specially because no injustice is going to be caused between the parties and as such a course would avoid multiplicity of proceedings. Section 13 of the Amending Act is ultra vires of article 19	 because	 construed literally the section cannot give protection to such of the tenants against whom proceedings are pending for more than 10 years or so	 a protection for a period more than what is envisaged by the Amending Act. This is clearly not what is intended or contemplated by the legislature. Giving retrospective effect to the section would only benefit a few and is not in the public interest of the tenants of the transferee landlords. The restriction is arbitrary and invades the right to property and is not saved by cl. (5) of article 19. The restriction is not reasonable.
