THE VICE CHAIRMAN DELHI DEVELOPMENT AUTHORITY Vs. NARENDER KUMAR &amp; ORS
benefit already available to the employee under the existing rule is arbitrary, discriminatory and violative of the rights guaranteed under Articles 14 and 16 of the Constitution. We are unable to hold that these decisions are not in consonance with the decisions in Roshan Lal Tandon [ (1968) 1 SCR 185 ] B.S. Vedera [ (1968) 3 SCR 575 ] and Raman Lal Keshav Lal Soni [(1983) 2 SCR 287] . 34. In the present context, none of the employees actually earned a second financial up-gradation. They undoubtedly became eligible for consideration. However, the eligibility ipso facto could not, having regard to the terms of the ACP scheme translate into an entitlement. The eligibility was, to put it differently, an expectation. To be entitled to the benefits, the public employer (here DDA) had to necessarily review and consider the employees records, to examine whether they fulfilled the eligibility conditions and, based on such review individual orders had to be made by DDA. In other words, second ACP up-gradation was not automatic but dependant on external factors. Furthermore, as held by this Court in M.V. Mohanan Nair (supra), MACP benefits are only an incentive meant to relieve stagnation – framed under the executive policy. Its continued existence cannot be termed as an enforceable right. 35. Such expectation is akin to a candidate being declared successful in a recruitment process and whose name is published in the select list. That, such candidate has no vested right to insist that the public employer must issue an employment letter, has been held by a Constitution Bench Judgment of this Court in Shankarsan Dash vs Union Of India (1991) 3 SCC 47 . Therefore, it is held that employees contention that they acquire a vested right in securing the second ACP benefit is insubstantial. 36. The employees in this case approached the High Court, complaining that their vested right, which was the assumed entitlement to be given by second ACP, was taken away by the MACP, introduced with effect from 01-09-2008, by an order dated 19-05-2009. No doubt, the MACP scheme is an executive order. Usually, such orders are expressed to be prospective. However, the executive has the option of giving effect to such an order, from an anterior date; especially if it confers some advantages or benefits to a sizeable section of its employees, as in this case. The nature of benefits- as emphasized by this court earlier, were by way of incentives. They are not embodied under rules. In such circumstances, a set of employees, who might have benefitted from the then prevailing regime or policy, cannot in the absence of strong and unequivocal indications in the later policy (which might be given effect to from an anterior date, like in this case), insist that they have a right to be given the benefits under the superseded policy. It is noteworthy that a larger section of employees would benefit from the MACP benefits, because they are to be given after 10-, 20- and 30-years service (as compared with two benefits, falling due after 12 and 24 years of service) and further that such benefits under MACP scheme are subjected to less rigorous eligibility requirements, than under the ACP scheme. 37. The myriad intricate details which the executive has to consider, while framing a scheme applicable generally, to a large section of the employees, may not always admit of one, or one set of solutions. To insist that a particular kind of benefit, hitherto applicable, should be continued for a set of employees, while the others should be governed by another, new set or scheme, would be imposing a significant burden on the administration, apart from swelling financial costs as well as administrative energies. Such directions would result in creating different time warps, rendering efficient administration of personnel policies impracticable. Sans palpable or facial arbitrariness, the courts should be circumspect in adding conditions, or tampering with such arrangements. In Ajoy Kumar Banerjee v Union of India (1984) 3 SCR 252 a five judge Bench of this court had emphasized this aspect in the following terms: 46…. The legislature however is free to recognise the degree of harm or evil and to make provisions for the same. Making dissimilar provisions for one group of public sector undertakings does not per se make a law discriminatory as such. It is well-settled that courts will not sit as super- legislature and strike down a particular classification on the ground that any under-inclusion, namely, that some others have been left untouched so long as there is no violation of constitutional restraints…… The same principle was reiterated by this Court in the case of State of Gujarat v. Shri Ambica Mills Ltd., Ahmedabad [1974 (3) SCR 760 ]. In that case, this Court was of the view that in the matter of economic legislation or reform, a provision would not be struck down on the vice of under-inclusion, inter alia, for the reason that the legislature could not be required to impose upon administrative agencies task which could not be carried out or which must be carried out on a large scale at a single stroke. It was further reiterated that piece meal approach to a general problem permitted by under-inclusive classifications, is sometimes justified when it is considered that legislatures deal with such problems usually on an experimental basis. It is impossible to tell how successful a particular approach might be, what dislocation might occur, and what situation might develop and what new evil might be generated in the attempt. Administrative expedients must be forged and tested. Legislators recognizing these factors might wish to proceed cautiously, and courts must allow them to do so…. This court is of the opinion that the same considerations apply in the present case. That, some employees could have benefitted more under the ACP benefits, if the MACP scheme had not been introduced from an earlier date, is no ground to hold so and compel an executive agency to grant the claimed benefits.
1[ds]In that decision, the question which arose for consideration was the correct date from which the MACP up- gradation scheme, was applicable to employees (below the rank of officer). This court held that the scheme had to be applied from 01.01.2006, and not the date designated by the concerned order (01.09.2008). The Armed Forces Tribunal (AFT) held that ACP benefits granted to employees is part of the pay structure which not only affects pay but also pension. ACP then ruled that it is not an allowance but a part of pay relied on a Government Resolution to hold that the MACP scheme was payable w.e.f. 01.01.2006. This Court in Balbir Singh Turn (supra) upheld that finding recorded by the AFT. Instructions issued on 30-5-2011 were found to be contrary to the Resolution dated 30-8-2008 as, according to the resolution 1-1-2006 was the effective date for implementation of MACPS in matters relating to pay and dearness allowance. There is no such parallel, in the facts of this case.25. In M.V. Mohanan Nair (supra) a three judge Bench of this court held, in the context of a dispute, which asserted that MACP benefits would result in regular promotional advancement, that:The change in policy brought about by supersession of ACP Scheme with the MACP Scheme is after consideration of all the disparities and the representations of the employees. The Sixth Central Pay Commission is an expert body which has comprehensively examined all the issues and the representations as also the issue of stagnation and at the same time to promote efficiency in the functioning of the departments. MACP Scheme has been introduced on the recommendation of the Sixth Central Pay Commission which has been accepted by the Government of India. After accepting the recommendation of the Sixth Central Pay Commission, the ACP Scheme was withdrawn and the same was superseded by the MACP Scheme with effect from 01.09.2008. This is not some random exercise which is unilaterally done by the Government, rather, it is based on the opinion of the expert body – Sixth Central Pay Commission which has examined all the issues, various representations and disparities. Before making the recommendation for the Pay Scale/Revised Pay Scale, the Pay Commission takes into consideration the existing pay structure, the representations of the government servants and various other factors after which the recommendations are made. When the expert body like Pay Commission has comprehensively examined all the issues and representations and also took note of inter-departmental disparities owing to varying promotional hierarchies, the court should not interfere with the recommendations of the expert body. When the government has accepted the recommendation of the Pay Commission and has also implemented those, any interference by the court would have a serious impact on the public exchequer.26. This court, in R.K. Sharma & Ors. (2021) 5 SCC 579,  commented on the effect of M.V. Mohanan Nair (supra) on the MACP scheme, especially the date from which it was operative. It was held that:The judgment in M.V. Mohanan Nair clinches the issue. Benefits flowing from ACP and MACP Schemes are incentives and are not part of pay. The Resolution dated 29-8-2008 is made effective from 1-9-2008 for implementation of allowances other than pay and DA which includes financial upgradation under ACP and MACP Schemes. Therefore, the respondents and other similarly situated officers are not entitled to seek implementation of the benefits of MACPS with effect from 1-1-2006 according to the Resolution dated 29-8-2008. Moreover, the implementation of MACPS by granting financial upgradation only to the next grade pay in the pay band and not granting pay of the next promotional post with effect from 1-1-2006 would be detrimental to a large number of employees, particularly those who have retired.27. It is therefore, quite clear that both Mohanan Nair(supra) and R.K. Sharma(supra), examined the MACP scheme; the latter, especially, ruled that the scheme was operable from 01-09-2008, and that the respondents officers are not entitled to seek implementation of the benefits of MACPS with effect from 1-1-2006 according to the Resolution dated 29-8-2008. Having regard to this clearly enunciated principle, which, in this courts opinion, stems from a correct reading of the scheme, the reasoning of the High Court, that the MACP scheme is operative not from 01-09-2008, but from 01-01-2006, is untenable. The mere circumstance that the resolution of the Government which led to adoption of the MACP also contained the effective date for implementation of the pay-benefits of the Pay Commission recommendations, did not obliterate the fact that the date from which the scheme was to be made effective, was another one.28. The submissions of the DDA, that the executive agencys considerations, while extending a benefit or new regime such as the promotion or career advancement program, is to be effective, involves decision making that is complex and nuanced, is justified. The date of operation of new pay scales cannot be per se the same when the operation of another scheme (which may also involve pay benefits) need not be the same. The shifting of dates (once settled by the executive after due deliberations) may seemingly have no consequences, but inevitably would have radical financial implications. Given these factors, it has been held, in previous decisions [Govt of AP v N. Subbarayadu 2008 (14) SCC 702 ; Ami Lal Bhat v State of Rajasthan (1997) 6 SCC 614 ; State of Bihar v. Ramjee Prasad (1990) 3 SCC 368 ; Union of India v. Sudhir Kumar Jaiswal (1994) 4 SCC 212  Union of India v. Shivbachan Rai (2001) 9 SCC 356  and Council of Scientific & Industrial Research v. Ramesh Chandra Agrawal (2009) 3 SCC 35]  that courts should in the absence of any facially compelling reason disclosing arbitrariness desist from stepping into the arena of decision making, and avoid directing their re- formulation or even requiring such schemes to be administered from any anterior period.29. The other reason why the High Court went wrong, in holding what it did, is that DDA is an autonomous – a statutory – organization. No doubt, it largely follows the Central Governments policies, in respect of pay and allowances, and other benefits for its employees. However, any revision of pay-structure or revision in other terms and conditions, of Central Government personnel cannot and do not automatically apply to the DDA; it has to consider the new or fresh scheme formulated by the Central Government, and adopt it, if necessary, after appropriate adaptation, to suit its needs. Therefore, the Central Governments MACP scheme did not apply to it automatically. The DDA decided to apply it, through an office order dated 06.10.2009 (Establishment Order, dated 6 October, 2009). The High Court has overlooked this aspect, and apparently assumed that the MACP scheme applied automatically, upon its adoption by the Central Government, to the DDA.31. Para 9 recognises the fact that if there is any ambiguity in the interpretation of the MACP scheme it would be resolved by the Department of Personnel and Training. It also clarifies in the last sentence that financial up- gradation would be granted till 31.08.2008 (given that the MACP scheme itself became operative on 01.09.2008), although the office memorandum was issued on 19.05.2009. In the opinion of this Court the undue influence placed upon the last sentence cannot be met much of by the employees given that the ACP scheme itself ended on 31.08.2008. This provision (i.e. Para 9) was made to cater to the situations where the grant of ACP benefits was under process, this would mean both types of benefits i.e. the first and the second up-gradation. Doubtlessly, the first up-gradation under the ACP scheme was to be granted after 12 years. If Para 9 were to be considered in the context of the first up- gradation it is a clarification to the effect that the individual concerned who has crossed 12 years service (and therefore became eligible and whose case is under active consideration) would get the ACP benefits. However, this provision cannot be understood as an independent transitional provision, enabling all employees awaiting the up-gradation to insist that the benefit of the ACP scheme should indefinitely continue despite its ceasing to exist after 31.08.2008.33. The concept of vested right has arisen for consideration before this court in several contexts especially with respect to alteration of service condition of public employees. That the Central Government in the exercise of its legislative powers conferred under provision of Article 309 of the Constitution can frame rules which has the force of law has been settled several decades ago. This court has also held that such rules can be made to operate from anterior date by giving retrospective effect to them. The determination of an anterior date for the operation of a rule which has the effect of nullifying or refacing intervening events or invalidating benefits which had been granted to public employees was held to be unconstitutional in State of Gujarat vs Raman Lal Keshav Lal Soni (1983) 2 SCR 287.  Several previous judgments of this Court dealing with the question that what is accrued or vested right were considered in Chairman, Railway Board v. C.R. Rangadhamaiah 1997 Supp (3) SCR 63 wherein the impugned rule in question sought to disturb the method of calculating the last pay drawn for the purposes of pension and related allowances. This impacted the pension disbursement of a large number of employees who had retired much earlier. The court observed that the amendments applied to employees who had already retired and were no longer in service on the date the impugned notifications were issued, and adversely impacted the pension they were drawing. In such context the court held as impermissible, those benefits which accrued or in other words had been actually enjoyed and were taken away by the devise of giving retrospective effect to the rule. The court observed as follows:22. In State of Gujarat v. Raman Lal Keshav Lal Soni [(1983) 2 SCC 33]  decided by a Constitution Bench of the Court, the question was whether the status of ex-ministerial employees who had been allocated to the Panchayat service as Secretaries, Officers and Servants of Gram and Nagar Panchayats under the Gujarat Panchayat Act, 1961 as government servants could be extinguished by making retrospective amendment of the said Act in 1978. Striking down the said amendment on the ground that it offended Articles 311 and 14 of the Constitution, this Court said:52. … The legislature is undoubtedly competent to legislate with retrospective effect to take away or impair any vested right acquired under existing laws but since the laws are made under a written Constitution, and have to conform to the dos and donts of the Constitution, neither prospective nor retrospective laws can be made so as to contravene Fundamental Rights. The law must satisfy the requirements of the Constitution today taking into account the accrued or acquired rights of the parties today. The law cannot say, twenty years ago the parties had no rights, therefore, the requirements of the Constitution will be satisfied if the law is dated back by twenty years. We are concerned with todays rights and not yesterdays. A legislature cannot legislate today with reference to a situation that obtained twenty years ago and ignore the march of events and the constitutional rights accrued in the course of the twenty years. That would be most arbitrary, unreasonable and a negation of history.23. The said decision in Raman Lal Keshav Lal Soni (1983) 2 SCR 287   of the Constitution Bench of this Court has been followed by various Division Benches of this Court. ( K.C. Arora v. State of Haryana (1984) 3 SCR 623 ; T.R. Kapur v. State of Haryana [ (1987) 1 SCR 584 ]; P.D. Aggarwal v. State of U.P. [(1987) 3 SCR 427]  ; K. Narayanan v. State of Karnataka [1994 Supp (1) SCC 44] ; Union of India v. Tushar Ranjan Mohanty [(1994) 5 SCC 450]  and K. Ravindranath Pai v. State of Karnataka [1995 Supp (2) SCC 246).24. In many of these decisions the expressions vested rights or accrued rights have been used while striking down the impugned provisions which had been given retrospective operation so as to have an adverse effect in the matter of promotion, seniority, substantive appointment, etc., of the employees. The said expressions have been used in the context of a right flowing under the relevant rule which was sought to be altered with effect from an anterior date and thereby taking away the benefits available under the rule in force at that time. It has been held that such an amendment having retrospective operation which has the effect of taking away a benefit already available to the employee under the existing rule is arbitrary, discriminatory and violative of the rights guaranteed under Articles 14 and 16 of the Constitution. We are unable to hold that these decisions are not in consonance with the decisions in Roshan Lal Tandon [ (1968) 1 SCR 185 ] B.S. Vedera [ (1968) 3 SCR 575 ] and Raman Lal Keshav Lal Soni [(1983) 2 SCR 287]  .34. In the present context, none of the employees actually earned a second financial up-gradation.

which had been given retrospective operation so as to have an adverse effect in the matter of promotion, seniority, substantive appointment, etc., of the employees. The said expressions have been used in the context of a right flowing under the relevant rule which was sought to be altered with effect from an anterior date and thereby taking away the benefits available under the rule in force at that time.
