P. Murugesan and Others v. State of Tamil Nadu and Others

B.P. JEEVAN REDDY, J. Heard the Counsel for the parties. Leave granted. The dispute is between the degree holders and the diploma holders in the engineering service under the Madras Municipal Corporation. The Corporation of Madras is governed by the Madras City Municipal Corporation Act, 1919. It employs a good number of engineers F in connection with the discharge of its duties. Till 1%5, there was only one category of supervisors. Recruitment to this category was by direct recruit­ ment of graduate engineers as well as by promotion from the lower category 9f overseers. Diploma holders were not eligible for direct appoint­ ment as supervisors; they were first appointed to the category of overseers and then promoted as supervisors. The category above the supervisors was G that of assistant engineers. Supervisors, whether directly recruited (graduates) or promotees (diploma-holders) were required to put in 20 years' service in the category of supervisors io become eligible for promo­ tion to the category of assistant engineers. No distinction was made as between the degree holders (graduates) and diploma-holders in the matter H of promotion or in the matter of eligibility criteria. MURUGESAN i·. STA~OF TAMIL NADU (REDDY, J.] 411 In the year 1965, say the a pellants (who are all graduate engineers), A the Corporation resolved (on 7 .. 65) to follow the rule in vogue in State Government service and apply 'the ratio of 3:1 between graduates and diploma-holders in the matter of promotion to the category of assistant engineers. The respondents who are all diploma-holders, deny that any such resolution was passed. According to them it was only a recommenda­ B tion of the Ad-hoc Committee constituted by the Corporation and that the said recommendation was never accepted as such by the Corporation. The respondents rely upon the Division Bench judgment dated 21.12.89 in writ appeal No. 990 of 1984 etc. holding that no such ratio was actually enforced in the Corporation Engineering Service. Be that as it may, some time prior to 1969, the Act was amended empowering the Government to frame rules C regulating the recruitment and conditions of service of the employees of the Corporation. In exercise of the said power, the Government of Tamil Nadu framed rules called Madras Corporation Engineering Service Rules (contained in G.0.M.S. No. 31 RD-LA dated 7.1.69). These rules applied only to class lA, lB and class II of engineering services under the Car- D poration and riot to other posts. The post of assistant engineer was in category III in class-II. Recruitment to this category was by (a) direct recruitment (b) promotion from the category of supervisors and (c) by appointment on deputation from the Government department. So far as promotion is concerned, a distinction was made as between degree-holders and diploma-holders. The graduate supervisors were required to put in a E minimum of five years service in the category of supervisors for becoming eligible for promotion, whereas the diploma-holder-supervisors were re­ quired to put in a minimum service of ten years as supervisors to become eligible for such promotion. At about this time, a practice developed whereunder graduate-supervisors were referred to as Junior engineers. The diploma-holders-supervisors (who are necessarily promotees in the category of supervisors) continued to be referred to as supervisors. In the year 1978 the Government ofTan;til N.adu altered the desig­ nations of the categori~ relevant before us by G.O.M.S. No. 954 dated 2.6.1978. Para-2 of theiG~O. stated that the diploma-holder-supervisors G shall be designated a5 junior engineers while the degree-holders-super­ visors (who had come to be known as junior engineers meanwhile) would be desi$'11lted as assistant engineers. Consequently the erstwhile post of assistant engineer was re-designated as assistant executive engineer. By G.O.M.S. No. 907 dated 20.5.1981, this change. in designation was given H 4U SUPREME COURJ REPORTS (1993) 1 S.C.R. A effect to and incorporated in the Statutory Rules issued in 1969 (Madras Corporation Engineering Service Rules). The recruitment and conditions of service of assistant engineers and juniors (formerly known together as Supervisors) were governed by the B by-laws made by the Corporation. In the matter of pay scales too, a distinction was being maintained between graduates and diploma-holders even when they were in the same category of Supervisors. The pay scale admissible to the category of supervisors was 325-650 but the graduates were given a higher start-their initial pay was fixed at 400. No such treatment was given to the diploma-holders. According to the appellants C there was yet another distinction from 1972 onwards; the pay-scales prescribed for the graduate engineers and dip!Oma-holder-engineers were different as per the particulars mentioned in para 33 of the S.L.P. They point out that in the counter filed to the Special Leave Petition, the respondents have not denied the said averment; they merely stated in para D 20 of their counter that the "allegations in paragraphs 33 to 36 are of no avail to the petitioner." Whether in pursuance of the Resolution of 1965 or otherwise, certain promotions were made to the category of assistant executive engineers, in the year 1978, applying the ratio of 3:1 as between graduate-engineers and E diploma-holder-engineers. We may refer to these two categories hereinafter as assistant engineers and junior engineers, since that was the designation given to them by G.O.M.S. No. 954 dated 2.6.1978. The said promotions were questioned by diploma-holders in a batch of writ petitions (2810 of 1978 etc.) in the Madras High Court. It was dismissed by a learned F Single Judge. On appeal, however, a Division Bench of that court held Gudgment dated 21.12.1989 in Writ Appeal No. 990 of 1984 etc.) that inasmuch as the Statutory Rules framed in 1969 did not provide for any such ratio, it is not open to the Corporation to prescribe such a ratio by a mere resolution or by an executive order. Accordingly, the Division Bench G quashed the said promotions. A Special leave petition preferred against the said judgment in this Court was dismissed on 25.1.1990. It is then that the Government of Tamil Nadu stepped in and amended the 1969 Rules providing for the said ratio of 3:1 by way ofG.O.M.S. No. 138 (Municipal Administration and Water Supply) dated 9th February, 1990. So far as relevant herein, the said G.O. prescribed the "ratio of 3:1 between the H degree holders and diploma holders" in the matter of promotion to the ...... \ - MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.] 413 assistant executive engineers. It was further provided that a junior engineer A {diploma-holder) who acquired an engineering degree or its equivalent during his service as junior engineer will be eligible for appointment as assistant executive engineer if he puts in three years of service in the Corporation Engineering Subordinate Service after obtaining the engineer- ing degree or its equivalept. The result of this amendment was that a B two-fold distinction came to be made between graduates and diploma­ holders in the matter of promotion to the post of assistant executive engineers. In addition to the hitherto existing distinction in the matter of length of qualifying period of service {10 years for diploma-holders/junior engineers as against 5 years for degree-holders/assistant engineers), the new restriction imposed by the said amendment was that the diploma C holders/junior engineers were restricted to only one out of four posts of assistant executive engineers; the remaining three were ·reserved for graduates/assistant engineers. (Of course, according to the appellant such a ratio was in vogue as a matter of fact since 1965. the respondents deny this assertion. Be that as it may, the ratio - or quota, as it may be called - D was statutorily imposed by the said amendment. The validity of the 1990 amendments, in particular the introduction of ratio of 3:1, was questioned by diploma-holders in the Madras High Court in a batch of Writ Petitions being Writ Petition 2943 of 1990 etc. A learned Single Judge dismissed the batch by his Judgment and Order dated E 21.3.1991, upholding the validity of the said ratio. On appeal, a Division Bench took a contrary view and quashed the amendment introducing the ratio of 3:1. In this appeal, the correctness of the view taken by the Division Bench is called in question. Mr. M.K Ramamurthy, learned counsel for the appellants' submitted that classification on the basis of academic qualifications is a well accepted basis for the purpose of promotion and that the Division Bench of the Madras High Court was in error in holding otherwise. He submitted that assistant engineers and junior engineers constituted different categories though performing similar functions and discharging similar respon- G sibilities. Their pay-scales were different-at any rate from 1972. Even earlier, the pay fJXation formula was different in the case of graduates. Even the Statutory Rules of 1969 made a distinction between the two categories inasmuch as while only five years' qualifying service was prescribed for graduates, ten years' qualifying service was prescribed for diploma-holders. H 414 SUPREME COURT REPORTS (1993) 1 S.C.R. A In sui;h a situation imposing an additional restriction upon the promotional chances of diploma hold~rs by the impugned amendment is neither incom­ petent nor can it be characterised as discriminatory. He submitted that right from 1972 onward, a clear distinction was being observed between the graduates and diploma-holders and that the impugned amendment is B but another step in the same process. On the other hand the learned counsel for the respondents-diploma­ holders submitted that wheiher graduates or diploma-holders, they were all in the category of supervisors till the year 1981. There was only one category of supervisors to which graduates were appointed by direct C recruitment and diploma-holders by promotion from the lower category of overseers. They performed identical functions and discharged identical responsibilities. They were inter-transferable. On some occasions, graduates (assistant engineers) were posted to assist a diploma holder Gunior engineer) in discharging certain duties. Even after 1978 when the D graduates-supervisors werti'designated as assistant engineers and diploma, holders-supervisors were designated as junior engineers, the same situation continued. In such a situation prescription of a quota as between them for promotion to the higher category is discriminatory and is violative of Articles 14 and 16 of the Constitution. Learned coun~el submitted that in any event once the diploma-holders were required to put in ten years' E service (as against five years' service in the case of graduates) in the category of supervisors for becoming eligible for promotion as assistant executive engineers, the eligible graduates and the eligible diploma-holders became equals in all respects. No distinction is permissible thereafter in the matter of and for the purpose of promotion. Creating such a distinction, F imposing a disability upon the diploma-holders, is not only unjust and inequitable, it is also a clear case of hostile discrimination. Lastly and alternatively counsel submitted that the vacancies which arose prior to the coming into the force of the impugned amendment, at any rate, should be filled up in accordance with the unamended Rules. It is pointed out that the impugned amendment is only prospective in operation. Section 87 of G the Act is relied upon in this behalf. It is true that theory of classification should not be carried too far lest it may subvert, perhaps submerge, the precious guarantee of equality, as pointed out by Chandrachud, J. in State of Jammu & Kashmir v. Triloki H Nath Khosa, [1974) 1 SCR 771. Minute and microcosmic classification MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.j 415 should not be permitted nor should the Court countenance "mini classifica- A tions based on micro distinctions", as pointed out by Krishna Iyer, J. in the same case. Looked at from this broad angle, it may appear there is some force in what the respondents contend viz., that. once the graduate-en­ gineers and diploma-holder-engineers constitute one class, perform same .duties and discharge same responsibilities, placing a restriction on the B diploma holders alone (limiting their chances of promotion to one out of four promotions, as has been done by the impugned Amendment) is not justified but this may be a too simplistic way of looking at the issue. We cannot fail to take note of the fact that right from 1974 i.e., since the decision of the Constitutions Bench in Triloki Nath Kilosa this Court has been holding uniformily that even where direct recruits and promotees are C integrated into a common class, they could for purposes of promotion to the higher .cadre be classified on the basis of educational qualifications. In the Kashmir Engineering Service, the post of assistant engineer could be filled both by direct recruitment as well as by promotion. There D were degree-holders and also diploma-holders in the category. By the Kashmir Civil Services (Revised Pay) Rules, 1968 it was provided that a diploma-holder-assistant engineer shall not cross the stage of Rs. 610 in the scale of Rs. 300-30-540-EB-35-610-EB-35-750, which was the scale applicable to assistant engineers. In 1970, Jammu and Kashmir Engineering (Gazetted) Service Recruitment Rules, 1970 were issued providing that the post of executive engineer (the next higher post) shall be filled only by promotion from among the assistant engineers, who possessed a bachelor's degree in engineering or its equivalent qualification provided they have put in seven years'· '·service in the assistant engineer's category .. Assistant en­ gineers who were not degree-holders were thus barred from promotion to the category of executive engineers. Both the Rules, namely 1968 Pay Rules and 1970 Recruitment Rules were questioned by diploma-holders in the J & K High Court. Though a learned Single Judge dismissed the writ petition, his judgment was reversed in appeal by the Division Bench. The Division Bench was of the opinion that where the employees were grouped together and integrated into one unit without reference to their qualifica- G tions, they form a single class in spite of initial disparity in the matter of their educational qualifications and that no discrimination is permissible to be made between them on the basis of such qualifications. On appeal this Court reversed the Judgment of the Division Bench. Two judgments were delivered, one by Chandrachud J. on behalf of himself A.N. Ray, C.J. and H A D.G. Palekar, and the other by Krishna Iyer, J. for himself and Bhagwati J. Chandrachud J. while affirming the principle that a classification niust be truely founded on substantial differences which distinguished persons grouped together from those left out of the group and that such differential attributes must bear a just and ·rational relation to the object sought to be achieved, stated the scope of the Judicial scrutiny in such matters in the following words : "Judicial scrutiny can therefore extend only to the con­ sideration whether the classification rests on a reasonable basis whether it bears nexus with the object in view. It cannot extend to embarking upon a nice or mathematical evaluation of the basis of classification, for were such an inquiry permissible it would be open to the courts to substitute their own judgment for that of the legislature or the rule-making authority on the need to classify or the desirability of achieving a particular object." The learned Judge held that judged from the above stand-point it was impossible to accept the proposition that the classification of Assistant Engineers into Degree-Holders and Diploma-Holders rests on any unreal or unreasonable basis. They accepted the plea that the said classification E was brought about with a view to achieving administrative efficiency in the Engineering services. The higher academic qualifications, the learned Judge held, is atleast presumptive evidence of a higher mental equipment. The learned Judge said "what is relevant is that the object to be achieved here is not a mere pretence for an indiscriminate imposition of inequalities F and the classification cannot be characterized as arbitrary or absurd. That is the farthest that judicial scrutiny can extend." The learned Judge referred to the earlier decision of this Court in State of Mysore & Anr. v. P. Narasing Rao, (1968] 1SCR407 and the Union of India v. Dr. (Mrs.) S.B. Kohli, AIR 1973 SC 811 to demonstrate that a distinction made on the basis of G academic qualifications was always upheld by this Court. Indeed, in the latter case, the relevant rule required that a professor of orthopaedics must have a post-graduate degree in the particular speciality. It was upheld as a relevant requirement, The learned Judge then explained the decision in Roshan Lal Tandon v. Union of India (upon which substantial reliance was placed by the respondents in that case) as an authority certainly for the H proposition that "no discrimination could be made between promotees and -{' MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.] 417 direct recruits by reference to the source from which they were drawn" but A that it does not bar a classification based upon academic qualifications. In the words of Chandarchud. J. Roshanlal Tandon's case is thus no authority for the proposition that if direct recruits and promotees are integrated into one class, they cannot be classified for purposes of promotion on a basis other than the one that they were drawn from different sources." Having B thus distinguished Roshan/a/ Tandon's case and Menyn v. Collector of Bombay, AIR 1967 S.C. 52, the learned Judge concluded : "We are therefore of the opinion that though persons appointed directly and by.promotion were intregrated into a common class for Assistant Engineers, they could, for purposes of promotion to the cadre of Executive En­ gineers, be classified on the basis of educational qualifica­ tions. The rule providing that graduates shall be eligible for such promotion to the exclusion of diploma-holders does not violate articles 14 and 16 of the Constitution and must be upheld." This decision clearly supports the appellants' contention and goes to sustain the validity of the impugned amendment. If the diploma-holders can be barred altogether from promotion, it is difficult to appreciate how and why is the rule making authority preciuded from restricting the promotion. The Rule making authority may be of the opinion, having regard to the efficien­ cy of the administration and other relevant circumstances that while it is not necessary to bar the diploma-holders from promotion altogether, their chances of promotion should be restricted. On principles, there is no basis for the contention that only two options are open to a rule making authority-either bar the diploma-holders altogether or allow them un­ restricted promotion on par with the graduates. This aspect has been emphasised by Venkatachaliah J. in Roop Chand Adlakha and Ors. v. D.DA. and Ors., [1988] 3 Supp. SCR 253 in the following words. "If Diploma-Holders - of course on the justification of the job-requirements and in the interest of maintaining a certain quality of technical expertise in the cadre - could validily be excluded from the eligibility for promotion to the higher cadre, it does not necessarily follow as an inevitable corollary that the choice of the recruitment 418 SUPREME COURT REPORTS (1993) 1 S.C.R. policy is limited only two choices, namely either to con­ sider them "eligible" or "not eligible". State, consistent with the requirements of the promotional-posts and in the interest of the efficiency of the service, is not precluded from conferring eligibility on Diploma-Holders condition­ ing it by other requirements which may, as here, include certain quantum of service-experience. In the present case, eligibility-determination was made by a cumulative­ criterion of a certain educational qualification plus a par­ ticular quantum of service experience. It cannot, in our opinion, be said, as postulated by the High Court, that the choice of the State was either to recognise Diploma' Holders as "eligible" for promotion or wholly exclude them as 11 not-eligible'.'· Counsel for the respondents however placed strong reliance upon D certain observations made by Bhagwati, J. in Mohammad Shujat Ali & Ors. etc. v. Union of India and Ors. etc., (1975) 1 SCR 449. After referring to the facts of, and the principles enunciated in, T.N. Khosa the learned Judge made the following observations: "But where graduates and non-graduates are both regarded as fit and, therefore, eligible for promotion, it is difficult to see how, consistently with the claim for equal opportunity, any differentiation can be made between them by laying down a quota of promotion for each and giving preferential treatment to graduates over non­ graduates in the matter of fixation of such quota. The result of fixation of quota of promotion for each of the two categories of Supervisors, would be that when a vacan­ cy arises in the post of Assistant Engineer, which, accord­ ing to the quota is reserved for graduate Supervisors, a non-graduate supervisor cannot be promoted to that vacancy, even if he is senior to all other graduate Super­ visors and more suitable than they. His opportunity for promotion would be limited only to vacancies available for non-graduate Supervisors. That would clearly amount to denial of equal opportunity to him." MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.] 419 ..). On the basis of the above observations it is argued that once the A diploma-holders are also held eligible for promotion, it is not permissible for the rule-making authority to make any distinction between graduates and diploma-holders. We cannot agree. As a matter of fact; this court in Shujat Ali case upheld the validity of the Andhra Pradesh rule which made a distinction between the graduate supervisors and non-graduate super- B visors in the ·matter of promotion to the higher categories on the ground ~ that in the erstwhile States of Andhra and Hyderabad, graduate supervisors were always treated as distinct and separate from the non-graduate super- visors, their pay scales were different; they were never really integrated into one class and graduate supervisors were called Junior Engineers. Accord- ingly, it was held that reducing the chances of promotion of non-graduate c supervisors vis-a-vis graduate supervisors was not discriminatory. (As we shall presently point out, the factual situation in Madras Corporation Engineering service is similar). The observations quoted above cannot be ~ read in isolation nor can they be read as running counter to the ratio of T.N. Khosa. Both decisions were rendered by Constitution Benches. In any event, the facts and circumstances of the case before us are akin to those D in Shujat Ali. Secondly as explained hereinbefore there would be no justification in principle for holding that the rule-making authority has only two options namely either to bar the diploma-holders altogether from ,>-.. promotion or to allow them equal opportunity with the graduate engineers in the matter of promotion. It must be remembered that the power of rule-making under the proviso to Article 309 bas been held to be legislative E in character. Vadera - A.I.R. 1%9 S.C. 118. If so, the test is whether such a restrictive view is permissible vis-a-vis legislature. If not, it is equally impermissible in the case of the rule-making authority under the proviso to Article 309. The only test that such a rule has to pass is that of Articles 14 and 16 - and to that aspect we may turn now. F )' The facts of this case, narrated hereinbefore, clearly disclose that long prior to the impugned amendment, a clear distinction was being maintained between these two categories. The 1969 Rules, as originally issued, prescribed a five years' qualifying service for graduate engineers G while prescribing ten years' qualifying service for diploma holders, though ~ earlier it was twenty years for both uniformly. No one ever questioned it. The graduates were designated as Assistant Engineers while Supervisors were designated as junio; engineers in the year 1978. This distinctive designations were recognised by and incorporated into the Statutory Rules (1%9 Rules) in the year 1981. No grievance was made on that count. Even H 420 SUPREME COURT REPORTS (1993] 1 S.C.R. A when both of them were in the same pay scale, the graduates were being given a higher start at Rs. 400 straightway, while no such benefit was given to a promotee. Further, from 1972 onwards, it appears, their very pay­ scales were different. It is thus clear that though they belonged to one class they represented two different categories, while it is true, they performed B similar duties and discharged similar responsibilities. It is asserte(j by the Respondent's counsel that there is also a common seniority list but this fact is denied by the appellant. According to them, there were two separate . seniority lists till 1979 and that when in 1979 a single seniority list was prepared, it was objected to by the graduates. Be that as it ·may, the question still remains whether it is not permissible to the rule-making C authority, if it thinks it necessary in the interests of administration to limit the promotional chance::i of non-graduate to one out or four vacancies, on the basis of academic qualifications. In the light of the Constitution Bench decision in Triloki Nath Khosa, we cannot say that it is not permissible. In Shamkant Narayan Deshpande v, Maharashtra Industrial Develop­ ment Corporation & Ors.., 1992 (2) Scale 857 a Bench consisting of P .B. Sawant and G.N. Ray, JJ. took the same view as we do in this case. We also agree with the basis upon which the learned Judges di.stinguished the decision in H.C. Sharma and .Ors. v. Municipal Corporation of Delhi and Others, [1983] 3 SCR 372. The learned counsel for respondents relied upon the decision in Punjab State Electricity Board and Anr. v. Ravinder Kumar Sharma and Ors., . [1987] 1 SCR 72, a decision rendered by a Bench ·comprising A.P. Sen and B.C. Ray, JJ .. the category of line-men in the service of the Punjab State F Electricity Board comprised both diploma-holders and others who may be referred to as non-diploma-holders. They censtituted one single category having a common seniority list. By means of the Rules issued under the proviso to Article 309, a quota was prescribed for diploma-holders, :he result of which was that diploma-holders who were far junior to the non··diploma-holders we~e promoted ignoring the non-diploma-holders. G The rule was held to be bad by the learned Subordinate Judge, Patiala. On appeal, the Additional District Judge, Pa ti ala affirmed the judgment. It was affirmed by the High Court as well. The matter was brought to this Court. This court affirmed the judgment of the High Court. A persual of the judgment shows that the attention of the Bench was not diawn either to H T.N. Khosa or to other decisions. Reference was made only to the obser- - MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.] 421 vations in Shujat Ali quoted hereinbefore and it was held that the distinc- A tion· made between the diploma-holders and non-diploma-holders was discriminatory and bad. Apart from the distinction on facts between that case and the case before us, it is evident that non-consideration of the T .N. K)losa and other decisions relevant under the subject has led to the laying down of a proposition which seems to run counter to T.N. Khosa. With great respect to the learned Judges who decided that case, we are unable B to accept the broad proposition flowing from the case. The counsel for the respondents then relied upon N. Abdul Basheer & Ors. etc. etc. v. KK. Karunakaran & Ors., (1989] 3 SCR 201 a decision of a Bench of three learned Judges. On an examination of the facts of that C case, it was held by Pathak, C.J. speaking for the Bench, that the history of the evolution of the Kerala Excise and Prohibition Subordinate Service does not show that the graduates and non-graduates were treated as two separate categories. The following observations bring out the factual posi- tion found in that case. nThe history has varied with the circumstances Prevailing before and after the reorganisation of the State on 1 November, 1956. Originally when more emphasis was laid on the induction of graduates, the ratio of graduate to non-graduate officers was maintained at 3:1 but from 9 September, 1974 the' ratio was changed inversely to 1:3. More non-graduates were now inducted into the Service. The trend shows, if anything, that it ran in favour of absorbing more non-graduates. The conditions pertaining to the service, and respecting which the constitution of the service varied from time to time, showed fluctuations. A consistent or coherent policy in favour of graduates was absent. This is not a case where the cadre of officers was kept in two separate divisions. It was a single cadre, and they were all equal members of it. There is no evidence that graduate Preventive Officers enjoyed higher pay than non-graduate Preventive Officers. The High Court has noted that the nature of the duties of Preventive Officers whether graduate or non-graduate was identical, and both were put_ to field work. Non-graduate Preventive Officers were regarded as competent as graduate Preventive Of- 422 SUPREME COURT REPORTS (1993] 1 S.C.R. A ficers. There is no evidence of any special responsibility being vested in graduate Preventive Officers. Once they were promoted as Excise Inspectors there was no distinc­ tion between graduate and non-graduate Excise lnspec­ tors. tt B It is thus clear that the facts of that case were entirely different and it is those facts which influenced the decision holding that no distinction can be made between graduates and non-graduates inspectors in the matter of promotion. The said decision, however, cannot be read as containing any proposition contrary to T.N. Khosa. We are, therefore, of the opinion C that the principle of the said decision cannot help the respondents. So far as the factual situation is concerned, the facts of the case before us do show, as discussed hereinbefore, that since 1%9 the graduate supervisors and non-graduate supervisors were treated differently in the matter of pay, designation and in the matter of promotion though they were discharging identical functions and duties. It may also be noticed in this connection that in the government service, the ratio of 3:1 as between graduates and diploma-holders has been in vogue since prior to 1965 and the corporation has been trying to implement the said ratio in its service too. Another argument urged by the learned counsel for the Respondents is that by precribing a longer qualifying period of service for diploma­ holders, they have been equated with the graduates and that thereafter no further distinction is permissible. We cannot agree. The distinction aforesaid was also in the matter of promotion and not for any other purpose. If that distinction is not discrimination, it is difficult to see how and why another distinction now created (quota rule) is discriminatory. Suppose, if these two requirements (i.e., longer qualifying service and quota rule) had been introduced at the same time, there could h_ave been no room for the present argument. The rule woulg_liave-beeii g~od. How G does it become bad, if they are introduced ·at atfferent times? Both relate to their eligibility and chances of promotion. To wit, the basic question is - if they can be barred altogether from promotion, <!SJield--in T.N. -Khosa, why can't their chances of promotion be restricted, curtailed or hedged in. Sri Thyagarajan, learned counsel for respondents 3 to 8 (diploma­ H holders) raised an alternative contention based upon Section 87 of the MURUGESAN v. STATE OF TAMIL NADli [REDDY, J.] 423 Madras City Municipal Corporation Act. Section 87 reads as follows : A "87. TIME WITHIN WHICH VACANCY IN CERTAIN POSTS MUST BE FILLED UP : (1) If a vacancy occurs in any office included in (* *) Class I,B or Class II, or any new office in Class 1-B or Class II is created, the council shall within three monthi; appoint any qualified and suitable person to hold such office. (2) If the State Government refuse to confirm the appointment so made, the council shall appoint some other qualified and suitable person within forty-five days from the receipt of the order refusing confirmation. (3). In default of any appointment being made in . accordance with sub-section (1) or sub-section(2), as the case may be, the State Government may appoint a person who in their opinion, is qualified and suitable to hold the office and such person shall be deemed to have been appointed by the council. (4) Pending an appointment under sub-section (1) or sub-section (2), the council may appoint a person to hold the office temporarily and assign to him such salary as it may think fit : Provided always that the salary so assigned shall not exceed the maximum fixed by the State Government by rules in respect of the office." The contention of the learned counsel is this: sub-section (1) of Section 87 obligates the council to fill up a vacancy within three months of occurrence of a vacancy by a qualified and suitable person. Sub-section (3) G provides the consequence of the· default of the council in making an appointment within the time prescribed by sub-section (1). In such even- -4.. tuality the State Government becomes entitled to appoint a person, who in their opinion is qualified and suitable for such office and the person so appointed shall be deemed to have been appointed by the council. Sub- H 424 SUPREME COURT REPORTS (1993] l S.C.R. A section (4) empowers the council to make a temporary appointment pend­ ing an appointment under section (1) or sub-section (2). [Sub-section (2) says that if the State Government refuses to confirm the appointment made -""' by the council under sub-section (1), the council shall have to appoint some other qualified and suitable person within forty-five days from the date of B receipt of the order of the Governmen\ refusing confirmation]. The counsel contends that in view oft' ,e said provision, the vacancies which arose three months prior to the date of the commencement of the impugned amend­ ment should be filled according to the unamended rules i.e., without reference to the quota. He relies upon the decisions of this Court in Rangiah v. Srinivasa Rao, (1983] 3 sec 284; P. Ga11eshwar Rao v. State of c A11dhra Pradesh, (1988] Supp. SCC 740; P. Mahendran a11d Others v. State of Kamataka a11d Ors., (1990 ] I SCC 411 and Devin Kalli & Others v. Kamataka Public Service Commission and Others, [1990] 3 SCC 157. On the other hand the learned counsel for the appellant submits D firstly, that this argument was not raised before the High Court and should not be allowed to be raised at this stage for the first time, secondly, he says Section 87 is not mandatory but only directory. The learned counsel also argues that in pursuance of the judgment of the learned Single Judge dated 21.3.1991 (upholding the validity of the impugned amendment and giving E certain directions in the matter of making promotions to the post of assistant executive engineer) and also because stay was refused by the Division Bench of High Court in the Writ Appeals preferred against the said judgment, the Corporation promoted thirty degree-holders including six appellants on 5.6.1991. In fact, it is stated, by an order dated 30.4.1991, F the Division Bench allowed the Corporation to make promotions pending the Writ Appeals, of course, subject to the result of the writ appeals. It is submitted further that by another Order passed in May, 1992, the Corpora­ tion promoted another twelve degree-holders and three diploma-hold~rs. It is alw brought to our notice that in the Special leave petition preferred against the judgment of the Division Bench, this Court stayed the reversion G of the appellants/petitioners by its order dated 14.9.1992 which order was continued by another order dated 21.9.1992. It is submitted that in the above circumstances a direction of the nature sought for by respondents 3 to 8 will mean the reversion of the appellants who have been promoted in pursuance of the order of the learned Single Judge. It is pointed out if this ' MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.] 425 Court is upholding the impugned amendment, it would not be just to A permit the reversion of degree-holders on the ground urged by the respon­ dents for the first time in this appeal. In our opinion Section 87 does indicate and manifest the concern of the Legislature that the vacancies occurring in the Corporation Service should not be kept unfilled for a period of more than three months. Sub-section (3) which provides for the consequence of default on the part of the council to abide by sub-section ( 1) emphasises the concern of the Legisiature. So also does sub-section (2). Sub-section (4) says that if there is going to be any delay or if a suitable or qualified person is not available, the council may appoint a person on temporary basis. The said provision C is, therefore, analogous to, and indeed more specific than rule 4 of the Andbra Pradesh Registration and Subordinate Service Rules considered in· Rangiah v. Srinivasa Rao. Accordingly it must be held that the learned counsel for respondents 3 to 8 is right in his submission that the vacancies occurring prior to three months before the date of commencement of the D impugned amendment ought to have been filled in accordance with the rules then obtaining. At the same time we cannot fail to recognise the force in the argument of the learned counsel for the appellants that the respon­ dents not having raised the said contention in the High Court i.e., before the learned Single Judge or the Division Bench should not be allowed to E raise the same in this Court for the first time. On a balancing of the contending equities, we are of the opinion that the following direction would be the appropriate one in the particular facts and circumstances of this case. The direction is this : The Corporation shall ascertain the vacancies in the category of Assistant executive engineers, that have arisen three months prior to the coming into force of the impugned amendment (introducing the quota of 3:1 as between degree-holders and diploma-holders) and shall work out the vacancies which would have g()ne to the diploma-holders if unamended Rules had been followed. The Corporation shall also ascertain which of G the diploma-holders would have been promoted in those vacancies. Such diploma-holders will be promoted in the vacancies that may be existing as on today and those that may arise in future. Until these diploma-holders are so promoted to the category of Assistant Executive Engineers, no degree-holders shall be be promoted. After these diploma-holders are so H 426 SUPREME COURT REPORTS [1993) 1 S.C.R. A promoted and thereafter, it is obvious the amended Rules shall be applied and followed. It is further directed that as and when a diploma-holder is promoted in pursuance of this direction, his promotion shall be given effect to from the date he ought to have been promoted. Such diploma-holders­ promotees shall be entitled to the benefit of seniority and pay-fixation B flowing from such retrospective promotions, but they shall not be entitled to the arrears of difference in salary for the period they have not actually worked as Assistant Executive Engineers. For the reasons recorded hereinabove the appeal is allowed subject to the direction made in the preceding paragraph. The Order of the C Division Bench of the Madras High Court in Writ Appeal No. 518 of 1991 is set aside. There shall be no orders to costs. V.P.R. Appeal allowed. )
