The Supreme Court examined the validity of the retrospective seniority benefit granted to Junior Engineers under G.O.Ms. No.54, which was issued under the powers conferred by the proviso to Article 309 of the Constitution of India. The Court held that the amendments made to the Special Rules for the Andhra Pradesh Engineering Service, which allowed for the counting of prior service as a Supervisor towards seniority as a Junior Engineer, were valid and did not violate any constitutional provisions. The appeals against the Full Bench decision of the Andhra Pradesh High Court were dismissed, upholding the rule's legality.
