Sushma Mutreja vs Union Of India & Ors

The Supreme Court held that the appellant, who was appointed as a Lower Division Clerk and later promoted to Upper Division Clerk under the Zoning Scheme, was entitled to be recognized as senior to certain respondents based on a revised seniority list issued in 1989, which complied with Rule 25 of the Central Secretariat Clerical Service Rules, 1962. The Court emphasized that seniority must be determined based on proper procedures and accurate data, and that erroneous seniority lists can be rectified through appropriate representations. The Court ruled in favor of the appellant, affirming her seniority over the respondents.
