Minimum service for promotion upheld as a valid eligibility rule; seniority cannot override prescribed qualification.

A uniform minimum period of approved service for consideration for promotion to Grade I was upheld as a valid eligibility condition. The Supreme Court held that experience in service is rationally connected to suitability for a higher post, and the rule-making authority could require eight years' approved service in the Section Officers' Grade for both direct recruits and promotees. Seniority within the cadre could operate only among candidates who already met the prescribed qualification and could not override eligibility. The amended proviso was therefore not arbitrary or violative of Articles 14 and 16, and the challenge to the promotion rule failed.

Issues: Whether the amended proviso to Rule 12(2) of the Central Secretariat Service Rules, 1962, requiring eight years' approved service in the Section Officers' Grade for consideration for promotion to Grade I, is arbitrary or violative of Articles 14 and 16 of the Constitution of India.

Analysis: The amended rule applied uniformly to direct recruits and promotees and prescribed a minimum length of service as a qualification for being considered for promotion. The Court held that experience in service is relevant to suitability for holding a higher post and that the rule-making authority was competent to prescribe such an eligibility condition. Seniority in the cadre could operate only among persons who already satisfied the prescribed qualification and could not override eligibility. The earlier validity of quota-rota seniority did not confer an automatic right to promotion without fulfillment of the amended service requirement.

Conclusion: The amended proviso was held not to be arbitrary, unreasonable, or violative of Articles 14 and 16; it was upheld against challenge.

Final Conclusion: The challenge to the amended eligibility condition for promotion failed, and the orders of the Tribunal were sustained.

Ratio Decidendi: Where the rule-making authority prescribes a uniform minimum period of approved service as an eligibility condition for promotion, seniority alone cannot displace that requirement, and such a rule is valid if experience bears a rational nexus to suitability for the higher post.
