The Allahabad High Court has reaffirmed a foundational principle of administrative law: once a public servant’s right to pension crystallizes upon superannuation, it cannot be extinguished by subsequent retrospective amendments to pension rules. This judgment provides critical clarity for thousands of ad-hoc employees across Uttar Pradesh whose service periods were wrongly excluded from pension calculations.
Background & Facts

The petitioner, Sanjay Kishore, was appointed as a Class-II Gazetted Officer in the State Training Service (Labour Department) on 22.07.1988 pursuant to a requisition through the Employment Exchange.

Relief Sought
The petitioner sought: (i) quashing of the rejection order dated 22.12.2020; (ii) direction to include ad-hoc service from 12.08.1988 to 13.02.2002 in qualifying service for pension; (iii) payment of all consequential pecuniary benefits; and (iv) interest at market rate on delayed payment of retiral dues.
The Legal Issue
The central question was whether retrospective application of U.P. Act No. 1 of 2021 can lawfully deprive a public servant of pensionary benefits based on ad-hoc service rendered prior to regularization, where the right to pension had already crystallized upon superannuation.
Arguments Presented
For the Petitioner
Learned counsel relied on the Constitution Bench judgment in Chairman, Railway Board v. C.R. Rangadhamaiah (AIR 1997 SC 3828) and its reaffirmation in Punjab State Cooperative Agricultural Development Bank Ltd. v. Registrar, Cooperative Societies (AIR 2022 SC 1349). It was submitted that the petitioner’s right to pension had vested on 31.03.2020, the date of superannuation, and was governed by Rule 3(8) of the U.P. Retirement Benefit Rules, 1961, as they stood then. Any retrospective amendment seeking to exclude ad-hoc service rendered before regularization would violate Articles 14 and 16 of the Constitution by divesting an accrued right. The petitioner’s service was continuous, in a permanent post, and recognized by successive promotions and pay scales.
For the Respondent
The State contended that the petitioner was not appointed strictly in accordance with recruitment rules and therefore his ad-hoc service was irregular. Reliance was placed on the U.P. Qualifying Service for Pension and Validation Ordinance, 2020, and its subsequent enactment as U.P. Act No. 1 of 2021, which explicitly excluded ad-hoc appointments made in contravention of recruitment rules from qualifying service. It was argued that the amendment was validly enacted and applied retrospectively to all pending claims.
The Court's Analysis
The Court undertook a rigorous analysis of the constitutional limits on retrospective legislation affecting vested rights. It emphasized that while the State may amend service rules prospectively, it cannot use retrospective operation to nullify rights that have already accrued.
"The exposition of the legal principles culled out is that an amendment having retrospective operation which has the effect of taking away the benefit already available to the employee under the existing rule indeed would divest the employee from his vested or accrued rights and that being so, it would be held to be violative of the rights guaranteed under Articles 14 and 16 of the Constitution."
The Court held that the petitioner’s service, though initially ad-hoc, was rendered in a substantive, pensionable vacancy, and was followed by regularization, promotion, and pay scale upgrades over a period of more than 13 years. His entitlement to pension had crystallized on the date of superannuation, 31.03.2020, under the then-existing Rule 3(8) of the 1961 Rules. The subsequent amendments introduced on 21.10.2020 (Ordinance) and 05.03.2021 (Act) could not be invoked to deprive him of a right already earned.
The Court further distinguished between legitimate expectation and vested/accrued right. While the former may be altered prospectively, the latter - once crystallized - is constitutionally protected. The petitioner’s continuous service, promotions, and recognition by the State over decades established a vested right, not a mere expectation.
The Court also relied on its own Division Bench judgment in Dr. Amrendra Narain Srivastava v. State of U.P. (Writ-A No. 61974 of 2011, decided on 01.03.2012), which had held similarly. The view taken in Special Appeal (Defective) No. 217 of 2024 was also affirmed.
The Verdict
The writ petition is allowed. The rejection order dated 22.12.2020 is set aside. The State is directed to include the period of ad-hoc service rendered by the petitioner from 12.08.1988 to 13.02.2002 in the computation of his qualifying service for pension. The total pension arrears, including all consequential benefits, shall be recalculated accordingly. With regard to interest on delayed payment, the State shall take a decision within one month from the date of receipt of a certified copy of this order, in accordance with law.
What This Means For Similar Cases
Vested Pension Rights Are Constitutionally Protected
- Practitioners must argue that any retrospective amendment excluding ad-hoc service is void if the employee’s pension right had crystallized before the amendment
- The date of superannuation is the critical cutoff for determining which rules apply
- Continuous service in a permanent post, even if initially ad-hoc, establishes a vested right
Ad-hoc Service Is Not Automatically Disqualified
- Ad-hoc appointments made against substantive vacancies are not inherently invalid
- Regularization, promotions, and pay scale upgrades confirm the State’s recognition of service
- The burden shifts to the State to prove the appointment was in clear and material violation of recruitment rules
Procedural Compliance Is Non-Negotiable
- Rejection orders must specifically address the vested right doctrine and cite applicable precedents
- Blanket exclusion of ad-hoc service under retrospective amendments is legally unsustainable
- Interest claims on delayed pension payments must be adjudicated within a reasonable timeframe
