V.K. DUBEY vs UNION OF INDIA .

The Supreme Court held that the seniority of employees who were shifted from the diesel locomotive side to the electrical locomotive side should be determined based on their deployment date in the electrical operations, as established in Rama Kant Chaturvedi v. Divisional Supdt. Northern Railway [1980 supp. SCC 621]. The Court ruled that previous service in the diesel unit cannot be counted for seniority purposes in the electrical unit, thereby allowing the appeals of the appellants who were reverted to their original positions. The judgment clarifies the principles governing inter se seniority in distinct operational units within the Railway Administration.
