Indra Sawhney v. Union of India (1992)

Indra Sawhney & Ors. v. Union of India (AIR 1993 SC 477) is a landmark constitutional judgment delivered by a nine-judge bench of the Supreme Court of India on 16 November 1992, commonly known as the Mandal Commission case. Its origins lie in the 1980 report of the Second Backward Classes Committee, chaired by B.P. Mandal, which recommended 27% reservation in central government employment for Other Backward Classes (OBCs) in addition to the existing 22.5% reserved for Scheduled Castes and Scheduled Tribes. After the report lay dormant for a decade, Prime Minister V.P. Singh announced its implementation on 7 August 1990, triggering nationwide anti-reservation protests — including self-immolations by upper-caste students — and a wave of petitions challenging the policy. The Supreme Court consolidated these petitions on 11 September 1990, and the case was argued before the nine-judge bench presided over by Chief Justice M.H. Kania, with Justice B.P. Jeevan Reddy ultimately authoring the lead opinion.

By a 6–3 majority, the Court upheld the constitutional validity of the 27% OBC reservation, ruling that Article 16(4) of the Constitution operates as a substantive and independent enabling provision — not merely an exception to equality — permitting the State to make targeted provisions for the adequate representation of historically marginalized communities in public employment. The majority accepted caste as a socially relevant (though not exclusive) indicator of backwardness, endorsing the Mandal Commission's eleven-indicator methodology that weighed social, educational, and economic factors in a 3:2:1 ratio. Three justices dissented, arguing that caste cannot be equated with "class" for constitutional purposes and that only economic criteria should govern eligibility.

The judgment established several constitutional rules that have governed India's reservation architecture ever since. First, total reservations cannot ordinarily exceed 50% of available positions in any given year or cadre — a ceiling that, when combined with SC/ST quotas (22.5%) and the newly confirmed OBC quota (27%), brought aggregate reservation to 49.5%. Second, the Court introduced the "creamy layer" doctrine, requiring the exclusion from OBC reservation benefits of those members of backward classes who have already achieved a relatively advanced social, economic, and educational status. Third, the bench held that reservation in promotions — as distinct from initial appointments — was unconstitutional, a ruling that the Parliament subsequently overrode through the 77th Constitutional Amendment (1995), which inserted Article 16(4A) specifically to protect promotional reservations for Scheduled Castes and Scheduled Tribes. Fourth, the Court struck down a parallel executive order attempting to reserve 10% of positions for economically backward sections among the forward castes, holding that economic disadvantage alone cannot constitute the basis for a "backward class" under the Constitution.

For Dalit communities — already holding reservations since Independence under Articles 15(4) and 16(4) — the Indra Sawhney judgment had layered consequences. On one hand, it left the 15% SC and 7.5% ST quotas intact and uncontested, and it affirmed that the constitutional framework protecting Dalit representation in the state apparatus was sound. The exclusion of Scheduled Castes and Scheduled Tribes from the creamy layer doctrine — a point not disturbed by this judgment — meant Dalits continued to benefit from reservations regardless of economic advancement within the community. On the other hand, the 50% ceiling effectively froze the total space available for all marginalized communities combined, making any future expansion of either OBC or SC/ST quotas constitutionally contested terrain. The judgment also sparked renewed debate about whether caste-blind economic criteria adequately recognized the specifically caste-rooted nature of Dalit oppression — a debate that continues to animate Dalit political thought.

The case has been modified but not overruled by at least five subsequent constitutional amendments (the 77th, 81st, 82nd, 85th, and 103rd) and remains the controlling precedent on the scope and limits of reservations under the Indian Constitution. The National Commission for Backward Classes was established by Parliament in 1993 as a direct institutional consequence of the judgment.
