Union Of India & Ors vs A. Durairaj (Dead)

The Supreme Court addressed the issue of promotion denial based on colour blindness, holding that the respondent's medical examination in 1976 was conducted negligently, leading to unjust denial of ad hoc promotion as Assistant Signal and Telecommunication Engineer (ASTE). The Court emphasized that the principles of equality and non-discrimination under Article 16 of the Constitution were violated, as other candidates with similar qualifications were promoted despite failing the written examination. The Court directed the appellants to consider the respondent for promotion with retrospective effect from 1976, thereby upholding the principles of fair opportunity in public employment.
