Summarize the following court judgment. ition (Civil) No. 13369 of 1984 (Under Article 32 of the Constitution of India). M. K. Ramamurthi and Uma Datta for the Petitioners. Shanti Bhushan and R.P. Kapur for the Respondents. The Judgment of the Court was delivered by VENKATACHALIAH	 J. This Writ Petition under Article 32 of the Constitution of India raises the question of the validity of Regulation 7 read with Schedule I of State Bank of Patiala (Officers ') Service Regulations	1979 ( Regulations ' for short) pertaining to the place ment and fitment of existing officers in the service of the State Bank of Patiala in the new grades and scales of pay. In the year 1959	 all "State Banks" State Bank of Patiala was one of them were made subsidiaries of the State Bank of India under (Subsidiary Banks) Act 1959. Section 63 of this Act provided: "63. Power of the State Bank to make regulations: (I) The State Bank may with the approval of the Reserve Bank	 make in respect of a subsidiary bank regulations	 not inconsistent with this Act and the rules made thereunder	 to provide for all matters for which provision is	 necessary or expedient for the purpose of giving effect to the provisions of this Act. (2) In particular and without prejudice to the generality of the foregoing power	 such regulations may provide for (a) to (I) . Omitted as unnecessary PG NO 482 (m) the conditions and limitations	 subject to which the subsidiary bank may appoint officers	 advisers and other employees and fix their remuneration and other terms and conditions of service; (n) to (y) . Omitted as not necessary Pursuant to and in exercise of the powers of Section 63 State Bank of Patiala (Officers ') Service Regulations	 1979 were promulgated. On the pattern of the recommendations made in regard to the Rationalisation and Standardisation of pay scales of nationalised banks made by what is known as the "Pillai Committee"	 the pay scales in State Bank of Patiala were also revised and restructured introducing new grades and scales. The Regulations were to take effect from 1st October	 1979. Regulation 7 read with Schedule I provided the placement and fitment of the existing officers of the bank in the new grades and scales Of pay. In the present case	 we are concerned with the placement and fitment of existing officers "Grade A" to which both the petitioners Sri Tarsem Lal Gautam and Sri C. V. Madan belong. The "Regulations" were promulgated. in exercise of the powers conferred by the State Bank of India (Subsidiary Banks) Act.1959	 by the Central Board of Directors of the State Bank of India in consultation with the Board of Directors of State Bank of Patiala and with the previous approval of the Reserve Bank of India. Regulation 4(1) introduced the following new grades and scales of pay for the officers in the Bank: "4(1) There shall be the following tour grades for officers with the scales of pay specified against each of the grades: (A) Top Executive Scale VII Rs.3000 125 3500 Grade Scale VI Rs.2750 125 3250 (B) Senior Management Scale V Rs.2500 100 2700 Grade Scale IV Rs.2000 100 2400 (C) Middle Management Scale III Rs.1800 75 Grade 2250 Scale II Rs. 1200 70 1550 75 2000 PG NO 483 (D) Junior Management Scale I RS.700 40 900 Grade 50 1 100 EB 1200 60 1800 The petitioners were "existing officers" as on the appointed date i.e. on 1.10.1979 in Grade A. Existing Officers in Grade A were placed in the corresponding new grades and scales of pay. The officers in the earlier existing Grade A in the pay scale of RS.1200 60 50 75 950 were placed in two different cadres and scale of pay	 viz.	 "Senior Management Grade Scale IV" with the pay scale of RS.2000 100 2400	 and "Middle Management Grade Scale III" with the pay scale of Rs. 1800 75 2250	 on the sole basis whether the officers had been promoted to the existing Grade A on or prior to 31.12.1975 or there after. The effect of Regulation 7 read with Schedule I was that all existing Grade A officers who had been promoted to that grade prior to 31.12.1975 were placed in the new scale ("Senior Management Grade Scale IV": RS.2000 100 2400) and those existing Grade A Officers who are promoted as such after 31. 12.1975 were placed in the new scale of "Middle Management Grade Scale Ill: RS.1800 75 2250". Petitioners challenged this classification of existing officers belonging to same grade and scale of pay into two different categories for fitment in the revised pay scales solely on the basis of date of their promotion as arbitrary and violative of Article l4 of the Constitution of India. Regulation 7 reads: "Subject to the provisions of Regulation 6	 existing officers serving in the grades and scales of pay mentioned in column I of the table given in schedule I to these regulations shall be placed as on the appointed date in the grades and scale specified there against in column ' of the said schedule. Provided that any difficulties or anomalies arising out of the above placement shall be referred to a committee of such persons as the Board or Executive Committee may appoint and the decision of that committee in this regard shall be final." Relevant entries in Schedule I are: PG NO 484 Schedule I [See regulation 7] Placement of existing Officers in the new grades and scales in the State Bank of Patiala Grade and scale Grade and scale immediately before the in which placed appointed date 1. Omitted as unnecessary 2. Officers 'A ' Grade Senior Management promoted as such on or Grade Scale IV December	 1975 Scale Rs.2000 100 2400 Rs.1200 60 1500 75 1950 4. Other Officers 'A ' Middle Management Grade Scale Rs.1200 60 Grade Scale III 1500 75 1950 Rs.1800 75 2250 5. Omitted as not necessary 6. do Sri Tarsem Lal Gautam was promoted as Grade A Officer on 1.12.1978. C.V. Madan was promoted as Grade A Officer on 1.12.1976. Both of them having been promoted after 31.12.1975 in the matter of their placement they	 by circular dated 23.7.1980 of the First respondent	 were held to fall outside entry 3 of Schedule I and within entry 4 of that Schedule and	 accordingly	 placed them in the 'Middle Management Grade Scale III" and not in the higher revised scale	Senior Management Grade Scale IV. It is to be mentioned here that second petitioner Sri C.V. Madan was removed from service on 30.12.1977. But the prayers in the petition	 to the extent they bear upon the correctness of his placement in so far as the benefits that he may be entitled to on that basis up to 30.12.1977	 shall survive. The main grievance of the petitioners is that the new Regulations merely brought about a revision of pay scales and that the differentiation amongst the existing "Grade A" Officers who were doing the same nature of work and who PG NO 485 would continue even after the placement in the new cadre to do the same work into two grades with different scales of pay based purely on the fortuitous circumstance of the date of their promotion to the existing "Grade A" is aroitrary. The effect of this is illustrated by the possibility that two officers doing the same duty both in the existing grades and in the revised grades are placed in two different scales of pay by reason alone that one of them had been promoted to "Grade A" on 31st December	 1975	 would go to the Higher Grade and scale of pay in the revised scale and the other would be placed in the lower scale by reason alone of the fact that he was promoted to the existing Grade the next day. In the memorandum of writ petition	 petitioners contend that existing officers belonging to Grade A are split into two groups with reference to their date of promotion to Grade A and this differentium is an irrational one. It is averred: ". . Thus	 the same class of officers i.e. Officers "A" Grade	 were bifurcated into two different categories with reference to wholly irrational	 illegal	 inequitable	 unreasonable and arbitrary criteria like the fortuitous event of promotion to "A" Grade on or before 31st December	 1975 . ." "The number of posts in SMGS IV were far more than the officers were arbitrarily cut off and intially placed in SMGS IV at that time . " In counter affidavit dated 15.3.1985 filed by the General Manager of the first respondent bank it is stated: ". It is denied that 'A ' grade officers were bifurcated into two different categories with reference to irrational	 illegal	 inequitable	 unreasonable and arbitrary criteria like the fortuitous event of promotion as alleged. This date was fixed having regard to the number of posts vacant with the respondent No. I in the Senior Management Grade Scale IV and the number of such posts came to 32 and it was further found that 26 officers had been promoted to then officer Grade 'A ' on or before December 31	 1975 . The seniority of the officers for placement in Senior Management Grade Scale IV was strictly maintained and no officer junior to the petitioner was placed in Senior PG NO 486 Management Grade Scale IV. Thus	 there was a rational differentia in placing certain officers in Senior Management Grade Scale IV and there was rational relationship of such placement to the objects sought to be achieved	 procuring the services of senior most experienced officers for the senior management Grade Scale IV posts. " Setting out the antecedents and the background for this restructuring of the cadres and pay scales it is averred: "It is submitted that in the year 1973	 a Committee known as Pillai Committee was appointed by the Government of India for bringing uniformity and standardisation in the conditions of service of the officers of various nationalised Banks. The recommendations of the Pillai Comrnittee were later on sought to be applied to the State Bank of India and its associate banks with suitablc modifications having regard to their special features . " I say that the new structure of grades and scales created by State Bank of Patiala [Officers`] Service Regulations	 1979	 does not lay down grades and scales corresponding to the earlier grades and scales	 but it is an entirely new structure created on the basls of recommendations of the Pillai Committee suitably adopted for the subsidiary banks of the State Bank of India with some modifications and there have been bifurcations	 which have resulted in intermediate grades and scales. As such	 it cannot be said that the new grades and scales correspond to gold grades and scales and they cannot be construed in a manner that a person who was in a particular grade or scale earlier	 would automatically get entitled to be placed in some specified corresponding grade and scale without any reference to the date of his promotion in an earlier grade or scale. It is very likely that whenever reorganization of cadres takes place in service	 some grades may have to be split up into more than one grade or class of posts	or more than one grade or class of posts may have to be merged to form a single cadre and as long as the inter se seniority of the officers is not disturbed	 it would be quite permissible to do so in law. In the present case also	 the grades and scales were reorganised	 but the inter se seniority of the vis a vis the petitioner was not disturbed and no officer PG NO 487 junior to the petitioner got higher grade or scale in the reorganised structure . " We have heard Shri M.K. Ramamurthy	 learned Senior Counsel in support of the petitioners and Shri Shantibhushan	 learned Senior Counsel for the first respondent bank. Though in addition to the challenge to the unconstitutionality of the classification of the existing A Grade Officers into two classes for purposes of fitment into the revised scales of pay	 petitioner	 Sri Tarsem Lal Goutam has alleged mala fies on the part of senior officers. It would appear	 that he had appeared before the Selection Committee for purposes of promotion from 'Middle Management Grade Scale III ' to the 'Senior Management Grade Scale IV ' and was allegedly	 over looked for promotion owing to what according to him was a hostile bias against him. There are lengthy averments in the memorandum of petition in regard to these grievances and equally lengthy reputations thereof in the counter affidavit. At the hearing	 Sri Ramamurthy	 did not rest the case on mala fides and bias but confined the arguments to the question of constitutionality of the criteria of classification in Entry 3 of Schedule I. Sri Ramamurthy contended that the exercise contemplated by the Regulations. in so far us pay scales were concerned	 was a mere revision of the scales of pay and that when in the year 1983	 the placements and fitments were undertaken with retrospective effect from 1.10.1979	the two sets of existing officers Grade A	 who were earlier doing the same kind of work and who even thereafter continued to do same kind of work	 were bifurcated into two classes on the mere fortuitous line of demarcation of the respective dates of their promotion to the Existing Grade A post. Sri Ramamurthy submitted that the line of demarcation was irrational in fact and impermissible in law. Those who had put in longer number of years of service	 learned counsel submitted	 would	 of course	 be entitled to and get higher pay in the same pay scale; but dividing the Officers of the same cadre into two groups for purposes of the benefit of revision of pay merely on the basis of the date of their promotion would be palpably arbitrary and violative of Article 14. Shri Ramamurthy contended even on the avowed basis of justification of the choice of the cut off date line of 31.12.1975	 namely	 that it was intended to bring about a uniformity in all the subsidiary banks would	 apart altogether from its legality	 by itself negate and detract PG NO 488 from the feebly suggested stand of the First Respondent that the cut off date was intended to secure the requisite number of senior and more experienced officers to man certain posts which were to be categorised against "Senior Management Grade Scale IV". Sri Ramamurthy submitted that the words 'promoted as such on or before 31.12.1975 ' occurring in item 3 of the Schedule I of the Regulations	 which has the effect of bringing about this hostile discrimination	 would require to be struck down. With those words so deleted from item 3 of Schedule I	 it was urged	 the provision would be purged of the vice of unconstitutionality. In support of his contention that mere seniority of service cannot support a classification for purposes of higher pay scales	 Sri Ramamurthy placed particular reliance on the pronouncement of this Court in P. Savita vs Union of India	 [1985] 1 Supp. SCR 101. In that case	 Senior Draughts men who were holding the posts as on 31.12. 1972	 were alone held entitled to a higher pay scale and those who had been promoted after 31.12.1972 were denied the benefit of the revision of the pay scale. The High Court did not see substance in the challenge of the Senior Draughtsmen who were denied the benefit to the Rule; but this Court relying on the principle of "Equal pay for Equal work" as recognised and effectuated in Randhir Singh vs Union of lndia; 	 held that the classification to be bad. Shri Ramamurthy invited our particular attention to the following observations of this court made while striking down the basis of the classification. ". The explanation is that this division is based on seniority. This cannot be accepted as sufficient to meet the requirements of law. By seniority	 a Senior Draughtsman will get higher pay with the increments that he earns proportionate to the number of years he is in service. Here that is not the case. It is the classification of the Senior Draughts men into two groups	 that is responsible for the higher pay . .In view of the total absence of any plea on the side of the respondents	 that the Senior Draughts men who are placed in the advantageous group. do not perform work and duties more onerous or different from the work performed by the appellants group	 it will have to be held that this grouping violates Article 14 of the Constitution . "For the purposes of the case on hand	 it is sufficient PG NO 489 to note that the classification between two groups of Senior Draughtsmen is without any basis. They do the same work	 they perform the same duties	 and as such the ratio of the decision in Randhir Singh 's case applies to this case with greater force . ." Shri Ramamurthy submitted that this is a full answer to the First Respondent 's contention and stated that the proper authority to plead any tenable justification for the purported classification in item 3 of Schedule I of the Regulations was the State Bank of India	 which has framed and promulgated the regulations and said that though the State Bank of India was impleaded as a party	 it did not enter appearance and seek to justify the principle justifying the classification. Shri Shanti Bhushan	 however	 submitted that the petitioners ' approach to the matter on the strength of Savitha 's case some what misconceived as the former case was one of Revision of pay scales simpliciter while the present Regulations do not contemplate a mere revision of pay scales of the existing cadres of officers but an exercise involving Rationalisation	 Standardisation and Re structuring of the whole Administrative set up of the management cadres of the Subsidiary Banks of the State Bank of India. Shri Shantibhushan submitted that where	 as here	 new categories of posts and new Scales of Pay	 not corresponding to the pre existing categories of posts and scales are created	 criteria will have to be evolved and applied for the subsumption and fitment of the existing officers into the new categories of posts and scales of pay. It might happen that all the Officers of any particular pre existing category	 it was urged	 cannot. en bloc	 be grafted on a particular new category or scale of pay and a fair and reasonable criteria would	 therefore	 require to be formulated which	 while protecting the inter se seniority of the existing officers would also make for their absorbtion and distribution in the new cadres and scales of pay on some reasonable basis. Shri Shanti bhushan submitted that the Regulations 4	 6 and 7 read with Schedule I envisage such an exercise and that	 indeed	 similar exercises have been undertaken and implemented both in the State Bank of India and in all the other subsidiary banks. Shri Shantibhushan submitted that any acceptance of the contentiones urged for by the petitioners would have the effect of introducing new and unforeseen complications and unsettlements in respect of a large number of similar cases. Referring to Savita 's case	 Shri Shantibhushan submitted that that was a case of a mere unreasonable withholding of the benefits of pay revision to some of the members who PG NO 490 were part of a well defined class. That apart	 that was case where Senior Draughtsmen were divided into two pay scales of Rs.330 560 and Rs.425 700 respectively and the important factor was that under the same pay revision the lesser grade of "Draughtsmen" had the benefit of revised pay scale of Rs.330 560. The unreasonableness and injustice of the case were writ large and set it apart. On a careful consideration of the matter	 we are pursuaded to the view that the 'Regulations ' did not bring about a mere revision of pay and that the analogy of precedents dealing with revision of pay would not be wholly determinative and that 1he contentions urged by Shri Shantibhushan are not without force. Regulation 6 required the categorisation of posts under the various new categories of posts. At the hearing	 Shri Shantibhushan brought to our notice that about 32 posts had been categorised against the 'Senior Management Grade IV" by the statutorily envisaged committee constituted for the purpose. It has been urged for the First Respondent Bank that the seniority and greater experience of the existing Officers in Grade A have been taken into account by the Regulations in the placement and fitment of the existing officers in the "Senior Management Grade Scale IV". This	 we think	 is not an instance to which the principle of equal pay for equal work could straight away be applied. Indeed	 the qualitative differences of regard to degrees of reliability and responsibility cannot be put aside as irrelevant. There cannot be any Thumb Rule to decide the invalidity of the provisions which recognise and provide for differentiation on the basis of higher experience	 reliability and responsibility. Indeed	 the observations of this Court All Customs & Central Excise Stenographers (recognised) and Others vs Union of India	 [1988] 2 JT 519 are apposite| "There may be qualitative difference as regards reliability and responsibility. Functions may be same but the responsibilities make a difference. One cannot deny that often the difference is a matter of degree and that there is an element of value judgment by those who are charged with the administration in fixing the scales of pay and other conditions of service. So long as such value judgment is made bona fide	 reasonably on an intelligible criteria which has a rational nexus with the object of PG NO 491 differentiation	 such differentiation will not amount to discrimination . " "The same amount of physical work may entail different quality of work	 some more sensitive	 some requiring more tact	 some less it varies from nature and culture of employment. The problem about equal pay cannot always be translated into a mathematical formula. If it has a rational nexus with the object to be sought for	 as reiterated before a certain amount of value judgment of the administrative authorities who are charged with fixing the pay scale has to be left with them and it cannot be interfered with by the Court unless it is demonstrated that either it is irrational or based on no basis or arrived mala fide either in law or in fact. " In Randhir Singh 's case itself it was recognised thus: " . . The higher qualifications for the higher grade	 which may be either academic qualifications. or experience based on length of service reasonably sustain the classification of the officers into two grades with different scales of pay. The principle of equal pay for equal work would be an abstract doctrine not attracting article 14 if sought to be applied to them. " In a recent pronouncement	 this Court dealt with a case	 the facts of which	 in comparison with those of the present one	 would render the latter as a fortiori position. In State of U.P. vs J.P. Chaurasia and Ors	 (Civil Appeal No. 56 of 1987 dated 27.9.1988 this Court noticed the question thus: " The question is whether it is permissible to have two pay scales in the same cadre for persons having same duties and having same responsibility ? Reversing the decision of the High Court which in the facts of the case answered in the negative this Court observed: ' 'The second question formulated needs careful examination. The question is not particular to the present case. It is pertinent to all such cases. It is a matter affecting the civil services in general. The question is whether there could be two scales of pay in the same cadre PG NO 492 of persons performing the same or similar work or duties. All Bench Secretaries in the High Court of Allahabad are undisputedly having same duties. But they have been bifurcated into two grades with different pay scales . " ". In service matters	 merit or experience could be the proper basis for classification to promote efficiency in administration. He or she learns also by experience as much as by other means. It cannot be denied that the quality of work performed by persons of longer experience is superior than the work of new comers . " We think that the principle of classification amongst the existing officers Grade A for purposes of fitment in the new dispensation brought about by the statutory regulations cannot be said to be unreasonable and arbitrary requiring to be struck down as violative of Article 14. Some arguments were advanced on the question if the number of pots categorised against "Senior Management Grade Scale IV" was higher than those filled up by the initial fitment under Regulation 7 read with Schedule I	 the excess number of posts would automatically go	 by way of placement	 to the existing officers in Grade A without the requirement of "promotion". The categorisation of posts under Regulation 6 is an exercise which is not in any way fettered by Regulation 7. If more number of posts are categorised under 'Senior Management Grade Scale IV ' than the number of existing officers placed into the higher scale pursuant to Regulation 7 read with Schedule I	 the proper construction to be placed on the scheme of the Regulation is that these extra number of posts in the higher scale would have to be filled up by promotion under Regulation 17 and not by a continuing process of placement and fitment. There is thus	 no merit in the writ petition which is accordingly dismissed. But in the circumstances	 we make no order as to costs. R.S.S. Petition dismissed.

The petitioners were working as Grade A officers on the appointed date	 i.e.	 1.10.1979 when the State Bank of Patiala (Officers ') Service Regulation	 1979 pertaining to the placement and fitment of existing officers in the new grades and scales of pay became effective. By virtue of Regulation 7 read with Schedule 1	 the pre existing Grade A officers were placed in two different grades Senior Management Grade and Middle Management Grade Depending on their date of promotion to Grade A being before or after 31.12.1975. The petitioners who were placed in the Middle Management Grade have challenged in their writ petition to this Court the validity of Regulation 7 read with Schedule I of the Regulations on the grounds that (i) the Regulations merely brought about a revision of pay scales; (ii) to divide the officers of the same cadre and doing the same nature of work into two groups for the purposes of mere revision of pay scales purely on the basis of the fortuitous circumstance of the date of their promotion to the existing Grade A would be arbitrary and violative of Article 14; and (iii) the number of posts in the revised senior grade were far more than the officers arbitrarily cut off and initially placed in that grade. P. Savita vs Union of India	 [1985] Suppl I S.C.R. 101 and Randhir Singh vs Union of India	 ; 	 relied upon. PG NO 479 PG NO 480 On behalf of the Bank it was contended that: (i) the Regulations did not contemplate revision simpliciter of pay scales of the existing cadres of officers; (ii) new categories of posts and new scales of pay not corresponding to the pre existing categories of posts and scales had been created and	 therefore	 new criteria had to be evolved and applied for the placement and fitment of the existing officers into the new categories of posts and scales of pay; (iii) all the officers of any particular pre existing category could not	 en bloc	 be grafted on a particular new category or scale of pay; and (iv) there was a rational differentia in placing certain officers in the Senior Management Posts as the cut off date was fixed having regard to the number of posts vacant in that grade on the appointed date. Dismissing the petition	 it was	 HELD: (l) The Regulations did not bring about a mere revision of pay. [490B C] (2) This was not a case to which the principle of 'equal pay for equal work ' could straight away be applied.
