Article 15(4)

Article 15(4) of the Constitution of India authorises the State to enact “special provisions” for the advancement of socially and educationally backward classes (SEBCs), Scheduled Castes (SCs) and Scheduled Tribes (STs). Unlike the broader equality guarantee of Article 15(1), this clause creates a constitutional foothold for affirmative‑action programmes, most visibly the reservation system in public‑sector employment and higher‑education institutions. Its insertion in 1976 marked a decisive shift from a purely formalist notion of equality to a substantive commitment to redress historic disadvantage. ## Historical Background The original Article 15, adopted in 1950, prohibited discrimination on grounds of religion, race, caste, sex or place of birth, but contained no provision for positive discrimination. Growing political pressure from Dalit and OBC leaders in the early 1970s prompted the 42nd Amendment, enacted on 3 January 1976, to insert clause (4). The amendment was passed under Prime Minister Indira Gandhi’s government, reflecting a broader agenda of social justice that also saw the creation of the National Commission for Scheduled Castes and Scheduled Tribes in 1978. The clause was intended to give constitutional legitimacy to reservation policies that had already been introduced by the state in the 1950s and 1960s. ## Constitutional Text and Key Provisions Article 15(4) reads: “The State may make special provisions for the advancement of any socially and educationally backward classes of citizens or for the Scheduled Castes and the Scheduled Tribes.” The wording deliberately limits the power to “special provisions” rather than a blanket entitlement, preserving the balance with Article 15(1)’s prohibition of discrimination. The clause is complemented by Article 16(4), which extends the same principle to appointments in public services, and by Article 335, which mandates that the claims of SCs and STs be considered in the distribution of public posts. Together, these provisions form the legal scaffolding for the reservation system. ## Mechanism and Implementation The operative mechanism translates the constitutional mandate into statutory quotas. The Central Educational Institutions (Reservation in Admission) Act 2006 codifies a 27 % reservation for OBCs, 15 % for SCs and 7.5 % for STs in central universities and institutes of national importance. In the civil‑service sphere, the Government of India’s 1995 amendment to the Constitution (Article 16(4)) set the same percentages for recruitment to Group A and B posts. The Supreme Court’s 1992 decision in Indra Sawhney v. Union of India upheld the 27 % ceiling for OBCs, while the 1995 judgment introduced the “creamy‑layer” exclusion, barring OBC individuals whose family income exceeds ₹8 lakhs (adjusted periodically). These mechanisms are administered by the Ministry of Social Justice and Empowerment and monitored through annual reports of the National Commission for Backward Classes. ## Landmark Judgments and Evolving Interpretation Indra Sawhney (1992) remains the cornerstone case, affirming the constitutionality of reservations while imposing the 50 % overall ceiling. The Court later refined the ceiling in M. R. Balaji v. State of Karnataka (2012), holding that the ceiling applies only to public‑sector jobs, not to educational seats. In 2008, the Supreme Court ruled in Ashoka University v. Union of India that private educational institutions may not be compelled to reserve seats, underscoring the distinction between public and private domains. More recently, the 2020 judgment in Janhit Mandal v. Union of India upheld a 10 % reservation for the economically weaker sections (EWS) under Article 16(6), illustrating the judiciary’s willingness to expand affirmative action beyond the original categories while keeping Article 15(4) as the primary source for SEBCs, SCs and STs. ## Current Status and Ongoing Debates As of 2023, the reservation matrix in central institutions stands at 27 % for OBCs, 15 % for SCs, 7.5 % for STs, and an additional 10 % for EWS, totalling 59.5 % of seats or posts. State governments often mirror these figures, though some, such as Tamil Nadu, have higher OBC quotas (up to 69 %). The “creamy‑layer” income threshold was raised to ₹10 lakhs in 2022, prompting debates about fiscal adequacy and the risk of “reservation fatigue.” The Women’s Reservation Bill, periodically re‑introduced since 1996, seeks to reserve 33 % of seats for women in legislatures and cites Article 15(4) as the constitutional basis for gender‑based affirmative action. Critics argue that the 50 % ceiling, derived from
