UNION PUBLIC SERVICE COMMISSION vs S. THIAGARAJAN .

The Supreme Court upheld the decision of the Central Administrative Tribunal which quashed the rejection of the first respondent's inclusion in the select list for promotion to the Indian Forest Service, emphasizing that the selection process must adhere to the IFS (Appointment by Promotion) Regulations, 1966. The Court noted that the High Court and Tribunal failed to recognize the statutory nature of these regulations and the implications of the amendments made to them. Consequently, the Court directed the official respondents to constitute a review DPC for the first respondent's inclusion in the select list within three months.
