Article 15 — Prohibition of Discrimination

Article 15 of the Constitution of India forms part of the cluster of equality provisions (Articles 14 to 18) within Part III, the chapter on Fundamental Rights. It operationalises the broad guarantee of equality before the law contained in Article 14 by naming specific prohibited grounds of discrimination. The drafting of Article 15 was shaped by the experience of caste-based and communal exclusion that the Constituent Assembly sought to dismantle, and it draws conceptual lineage from the equal protection clause of the Fourteenth Amendment to the United States Constitution. The Article came into force with the Constitution on 26 January 1950, and its text has since been amended four times — by the First (1951), Ninety-third (2005), One Hundred and Third (2019), and related constitutional amendments — to accommodate affirmative-action measures the original framers either omitted or which judicial interpretation had constrained.

The operative mechanics of Article 15 rest on its first two clauses. Article 15(1) directs that the State shall not discriminate against any citizen on grounds only of religion, race, caste, sex, or place of birth, or any of them. The word "only" is decisive: discrimination founded on these grounds in combination with other permissible considerations may survive scrutiny, whereas discrimination resting solely on a listed ground is void. Article 15(2) extends the prohibition horizontally — beyond State action to private conduct — by barring any citizen from being subjected, on the same grounds, to disability or restriction regarding access to shops, public restaurants, hotels, and places of public entertainment, or to the use of wells, tanks, bathing ghats, roads, and places of public resort maintained wholly or partly out of State funds or dedicated to public use. This horizontal reach distinguishes Article 15(2) from most Fundamental Rights, which bind only the State.

The remaining clauses constitute the enabling exceptions that prevent the non-discrimination guarantee from freezing existing inequalities. Article 15(3) permits the State to make special provision for women and children. Article 15(4), inserted by the Constitution (First Amendment) Act, 1951 in response to State of Madras v. Champakam Dorairajan (1951), empowers the State to make special provision for the advancement of socially and educationally backward classes and for the Scheduled Castes and Scheduled Tribes. Article 15(5), added by the Ninety-third Amendment in 2005 and upheld in Ashoka Kumar Thakur v. Union of India (2008), authorises reservation in educational institutions, including private unaided institutions but excluding minority institutions under Article 30(1). Article 15(6), introduced by the One Hundred and Third Amendment Act, 2019, enables up to ten per cent reservation for economically weaker sections (EWS) not already covered by existing reservation schemes.

Contemporary application of Article 15 is visible across India's policy and judicial landscape. The EWS reservation under Article 15(6) was upheld by a 3:2 majority of the Supreme Court in Janhit Abhiyan v. Union of India on 7 November 2022, with the Bench rejecting the argument that economic criteria alone breached the basic structure. The Ministry of Social Justice and Empowerment, headquartered in New Delhi, administers central reservation policy under these provisions. In Navtej Singh Johar v. Union of India (2018), the constitutional reading of "sex" informed the decriminalisation of consensual same-sex relations, and progressive jurisprudence has begun reading "sex" to include sexual orientation as an analogous prohibited ground.

Article 15 must be distinguished from adjacent equality provisions. Article 14 guarantees equality before the law and equal protection to all "persons", including non-citizens, and applies a general reasonableness test; Article 15 is narrower, protecting only citizens and only against the five enumerated grounds. Article 16, by contrast, governs equality of opportunity specifically in matters of public employment and contains its own parallel backward-class reservation clause in Article 16(4) — practitioners must not conflate Article 15(4) educational reservations with Article 16(4) employment reservations, as the two operate under distinct ceilings and jurisprudence. Article 17, abolishing untouchability, addresses a specific manifestation of caste discrimination that Article 15(2) also touches.

Edge cases and controversies persist. The "creamy layer" exclusion, mandated for Other Backward Classes since Indra Sawhney v. Union of India (1992), interacts with Article 15(4) and (5) but was initially held inapplicable to the EWS quota's income ceiling. The interaction between Article 15(5) and minority institutions' autonomy under Article 30 generated litigation in Pramati Educational Trust v. Union of India (2014). The reading of "place of birth" against "residence" — the latter not being a prohibited ground — permits domicile-based reservations in some contexts, a recurring source of inter-state friction. The aggregate breach of the fifty-per-cent reservation ceiling by the EWS quota remains a contested question of constitutional principle.

For the working practitioner — whether a UPSC aspirant preparing the GS Paper II polity syllabus, a desk officer drafting affirmative-action policy, or a litigator — Article 15 is indispensable because it converts the abstract promise of equality into enforceable, ground-specific prohibitions while simultaneously authorising the compensatory measures that define India's social-justice architecture. Mastery requires holding two ideas in tension: the negative command against invidious discrimination and the positive licence for protective discrimination, each amended and litigated repeatedly since 1950.
