MACP Scheme benefits are incentive-based and effective from 01.09.2008, not 01.01.2006.

The Petitioners are retired Group ‘A’ officers of the Intelligence Bureau who retired between January 2006 and September 2008.

During their service, they were governed by the Assured Career Progression (ACP) Scheme of 1999.

Following the 6th Central Pay Commission, the Government issued a Resolution on 29.08.2008 revising pay scales w.e.f. 01.01.2006 and contemplating a new Modified Assured Career Progression (MACP) Scheme.

The MACP Scheme was formally operationalized via Office Memorandum (OM) dated 19.05.2009, but with an effective date of 01.09.2008.

The Petitioners, having retired before 01.09.2008, were denied 3rd financial upgradation under MACP.

They challenged the Central Administrative Tribunal's (CAT) dismissal of their claim, which held that the scheme was not retrospective to 01.01.2006.

Whether the Modified Assured Career Progression (MACP) Scheme is a part of the revised "pay structure" effective from 01.01.2006 or an "allowance/incentive" effective from 01.09.2008.

Whether the Petitioners, who superannuated between 01.01.2006 and 31.08.2008, are entitled to the 3rd financial upgradation under the MACP Scheme.

The Court relied on the distinction established in the Government Resolution dated 29.08.2008, which made revised pay scales and dearness allowance effective from 01.01.2006, while other allowances were effective from 01.09.2008.

It applied the principles from *Union of India v. M.V. Mohanan Nair* (2020) and *Union of India v. R.K. Sharma* (2021), which established that MACP is an incentive scheme to relieve stagnation and a condition of service, rather than a component of the pay structure.

It further followed *Union of India v. Virender Singh* (2022) and *Vice Chairman, DDA v. Narender Kumar* (2022), which conclusively held that the MACP Scheme is applicable only from 01.09.2008 and does not apply retrospectively.

The Court reasoned that the Resolution dated 29.08.2008 explicitly confined the 01.01.2006 effective date to pay scales and DA, whereas MACP was a separate incentive-based policy.

Although the earlier decision in *Union of India v. Balbir Singh Turn* (2018) suggested MACP impacted pay and should be retrospective, the Court noted that larger Benches in *M.V. Mohanan Nair* and *R.K. Sharma* had since clarified that MACP is not part of the "pay structure".

The Court observed that since the Petitioners retired before the operational date of 01.09.2008, their rights were governed solely by the then-existing ACP Scheme.

It emphasized that the executive's decision to fix a cut-off date for policy implementation is a matter of fiscal and service policy that does not violate Article 14 unless shown to be manifestly arbitrary.

Consequently, the Petitioners, having retired prior to the implementation date, have no enforceable right to claim MACP benefits.

The Delhi High Court dismissed the writ petition, upholding the CAT’s order and finding no infirmity in the denial of financial upgradation to the Petitioners.
