Prospective promotion rules amendment: reduced pass mark could not revive earlier promotion rights or unsettle settled promotions.

A modification reducing the departmental examination pass mark from 60% to 50% was held to operate prospectively from 26.05.2008 and could not be applied retrospectively to revive an earlier promotion claim. Retrospective application was rejected because the earlier results had been declared, promotions had been effected under the unamended rules, and reopening the matter would unsettle accrued rights and settled third-party promotions. The constitutional challenge under Articles 14 and 16(1) also failed, as a prospective commencement date was not treated as hostile discrimination. The attempt to reopen the promotion dispute was further barred by res judicata, constructive res judicata, and delay and laches.

Issues: (i) Whether the modified departmental examination rules reducing the pass percentage from 60% to 50% could be applied retrospectively so as to confer promotion-related benefits on the petitioner from an earlier year. (ii) Whether the stipulation making the reduced pass percentage operative only from 26.05.2008 was arbitrary or violative of Articles 14 and 16(1) of the Constitution of India, and whether the challenge was barred by finality of earlier litigation and delay.

Issue (i): Whether the modified departmental examination rules reducing the pass percentage from 60% to 50% could be applied retrospectively so as to confer promotion-related benefits on the petitioner from an earlier year.

Analysis: The reduced pass percentage was introduced by the modified rules as a prospective change and was expressly made operative only from 26.05.2008. The earlier examination results had already been declared under the unamended rules, promotions had been effected on that basis, and retrospective application would unsettle accrued rights and require reopening of settled promotions. The petitioner's claim sought to revive a matter already decided against him under the earlier regime.

Conclusion: Retrospective application of the reduced pass percentage was rejected.

Issue (ii): Whether the stipulation making the reduced pass percentage operative only from 26.05.2008 was arbitrary or violative of Articles 14 and 16(1) of the Constitution of India, and whether the challenge was barred by finality of earlier litigation and delay.

Analysis: The Court held that prospectivity of the amendment did not amount to hostile discrimination because there is no right to promotion without satisfying the applicable qualification criteria in force at the relevant time. The cut-off date was treated as a valid prospective commencement date and not an impermissible classification. The petitioner had already litigated the same promotion claim unsuccessfully up to the Supreme Court, and the later challenge was held to be barred by res judicata, constructive res judicata, and delay and laches, especially because reopening the issue would affect the rights of third parties who had already been promoted.

Conclusion: The constitutional challenge and the attempt to reopen the promotion claim were rejected.

Final Conclusion: The challenge to the Tribunal's order failed, and the petitioner was held not entitled to retrospective benefit under the modified rules or any consequential promotion relief.

Ratio Decidendi: A statutory or regulatory amendment altering promotion qualifications operates prospectively unless expressly or by necessary implication made retrospective, and it cannot be applied to unsettle accrued rights, settled promotions, or issues already concluded by final adjudication.
