STATE OF T.NADU vs SESHACHALAM

The Supreme Court addressed the issue of promotions within the Tamil Nadu Secretariat Service, specifically regarding the exclusion of the Finance and Law Departments from the 'one unit' system established by the Special Rules. The Court held that the retrospective amendment of the Service Rules by G.O.Ms. No.30, which aimed to rectify the promotion disparities, was valid and necessary to ensure fairness among employees. The Court upheld the Tribunal's decision that employees in other departments should not be deprived of promotion benefits due to arbitrary departmental allocations, thereby reinforcing the principle of equal opportunity in public service.
