Article 15 of the Constitution

Article 15 of the Constitution of India is the primary anti‑discrimination clause, forbidding the State from treating any citizen differently on the basis of religion, race, caste, sex, place of birth or any other specified ground. Enacted on 26 January 1950, it embodies the constitutional promise of equality and simultaneously authorises the legislature to make “special provisions” for groups that have historically been disadvantaged. The article’s dual character—prohibitive and enabling—makes it a cornerstone of India’s social‑justice architecture and a frequent reference point in Supreme Court jurisprudence.

Historical Background

The framers originally drafted Article 15 without an explicit “special provisions” clause, reflecting a liberal egalitarian ideal. The first major alteration came after the Supreme Court’s decision in State of Madras v. Champakam Dorairajan (1951), which struck down caste‑based reservations in educational institutions; Parliament responded with the First Amendment (1951) inserting clause 15(4) to permit affirmative action for “backward classes.” Subsequent amendments expanded the protective net: the Seventy‑first Amendment (1992) added “sex” to the prohibited grounds, the Eighty‑first Amendment (2000) incorporated “disability,” and the Ninety‑third Amendment (2006) introduced clauses 15(5) and 15(6) to enable reservations for socially and educationally backward classes, and for Scheduled Castes and Scheduled Tribes respectively.

Key Provisions

Article 15(1) enumerates the five prohibited grounds—religion, race, caste, sex, place of birth—while clause 15(2) extends the ban to “any other ground” as interpreted by the judiciary. Clause 15(3) bars discrimination in access to public places, facilities, and services, a provision that underpins the right to use streets, parks, and government‑run hospitals without prejudice. Clause 15(4) empowers the State to make “special provisions” for the advancement of any socially or educationally backward class, a textual basis for reservation policies; clause 15(5) specifically targets “socially and educationally backward classes of citizens,” and clause 15(6) reserves this power for Scheduled Castes and Scheduled Tribes, thereby codifying the reservation system in higher education and public employment.

Mechanism and Legislative Power

When Parliament enacts a law that creates a reservation or preferential scheme, it must cite the relevant clause of Article 15 as its constitutional foundation. The law typically specifies the percentage of seats or posts reserved, the criteria for identifying beneficiaries, and the duration of the measure; for example, the Constitution (Eighty‑Third Amendment) Act 2002 fixed a 27 % reservation for OBCs in central government jobs. Judicial review operates through the “reasonable classification” test: the State must demonstrate that the classification serves a legitimate aim of ameliorating historical disadvantage and that the means are proportionate. Administrative agencies such as the Ministry of Social Justice and Empowerment issue detailed guidelines—like the 2015 “Reservation Policy for Central Educational Institutions”—to operationalise the constitutional mandate.

Landmark Judgments

Beyond Champakam Dorairajan, the Supreme Court has repeatedly invoked Article 15 to expand civil liberties. In E.P. Royappa v. State of Tamil Nadu (1974), the Court articulated the “lawful equality” doctrine, holding that any arbitrary classification violates Article 15. The 2018 judgment in Navtej Singh Johar v. Union of India read down Section 377 of the Indian Penal Code, declaring that criminalising consensual same‑sex conduct amounted to discrimination on the basis of sex and “other grounds” under Article 15. More recently, the 2021 Indian Young Lawyers Association v. State of Kerala decision struck down a ban on women’s entry to the Sabarimala temple, emphasizing that the exclusion violated the “place of birth” and “sex” prohibitions in Article 15.

Current Status and Implementation

As of 2024, the Ministry of Law and Justice reports that over 1.5 crore (15 million) beneficiaries have accessed reservation benefits in central institutions, reflecting the article’s expansive reach. The National Commission for Scheduled Castes and the National Commission for Scheduled Tribes regularly monitor compliance with clauses 15(5) and 15(6), publishing annual reports that document both successes and persistent gaps in representation. Civil‑society groups continue to challenge residual discriminatory practices, such as caste‑based denial of services in private establishments, invoking Article 15(3) to seek enforcement through consumer courts. The article remains a living instrument, shaping debates on gender equality, disability rights, and the future of affirmative action in a rapidly diversifying society.
