Tamil Nadu Administrative Service ... vs Union Of India & Ors

The Supreme Court addressed the issue of encadrement of State Deputation Reserve and Temporary posts in the IAS cadre under the IAS (Fixation of Cadre Strength) Regulations, 1955. The Court held that the amendments made to the IAS (Appointment by Promotion) Regulations, 1955, which included these posts in the cadre strength, did not adequately address the petitioners' concerns regarding the exclusion of numerous posts. The Court emphasized the need for a genuine cadre review to ensure that the legitimate rights of State service officers to be promoted to the IAS are upheld under Rule 8 of the IAS (Recruitment) Rules, 1954.
