G.K. Mohan And Others vs Union Of India And Others

The Supreme Court upheld the validity of Rule 6(4)(a) of the Defence Research & Development Organization, Technical Cadre Recruitment Rules, 1995, stating it does not violate Article 14 or Article 16 of the Constitution. The Court established that categorization based on educational qualifications is permissible and does not constitute discrimination. The appeals by the Chargemen grade II were dismissed as they lacked the qualifications required for a higher grade, affirming that different classes (Chargemen and Draughtsmen) do not invoke Article 14's protections against discrimination.
