Equality

1. Equality as a constitutional principle

The Preamble promises equality of status and opportunity. Part III translates this commitment into enforceable rights, while the Directive Principles support its social and economic foundations. Article 38 directs the State to minimise inequalities; Article 39 includes equal pay for equal work for men and women; and Article 46 promotes the educational and economic interests of weaker sections, especially Scheduled Castes and Scheduled Tribes. These Directive Principles are not independently enforceable in courts, but guide legislation and constitutional interpretation.

Formal equality requires the same rules for similarly situated persons. Substantive equality recognises that identical treatment may perpetuate disadvantage where starting conditions differ. Scholarships, accessible facilities for persons with disabilities and constitutionally authorised reservations can therefore advance equality rather than contradict it. Equality does not require every distinction to disappear: it requires distinctions to have a constitutionally defensible basis.

Most equality guarantees operate against the State, understood through Article 12 to include governments, legislatures, local authorities and other qualifying authorities. Important exceptions have horizontal reach: Article 15(2) addresses specified exclusion from public facilities, and Article 17 prohibits untouchability by private persons as well. Fundamental rights can be enforced through Article 32 before the Supreme Court and Article 226 before High Courts.

2. Article 14: classification, equal protection and arbitrariness

Article 14 guarantees equality before the law and equal protection of the laws within India. Equality before law conveys the absence of special legal privilege; equal protection requires comparable treatment of persons in comparable circumstances. The provision covers citizens, foreigners and, where applicable, juristic persons. It does not prohibit constitutionally recognised immunities, such as those provided to the President and Governors under Article 361.

Article 14 forbids class legislation but permits reasonable classification. A classification must satisfy two connected tests: it must rest on an intelligible differentia distinguishing those included from those excluded, and that differentia must have a rational nexus with the law's objective. For example, a targeted benefit for residents of a drought-affected area may be justified by the objective of drought relief; an unrelated distinction would not be.

Judicial interpretation extends beyond classification. In E. P. Royappa v. State of Tamil Nadu (1974), the Supreme Court connected equality with protection against arbitrariness. Maneka Gandhi v. Union of India (1978) reinforced the relationship between Articles 14, 19 and 21 and the requirement of fair, just and reasonable procedure. Shayara Bano v. Union of India (2017) is significant for applying manifest arbitrariness as a ground to invalidate legislation.

• Exam distinction: different treatment is not automatically discrimination; the constitutional basis and purpose matter.
• Negative equality is not a right: an unlawful benefit granted to one person does not entitle others to claim the same illegality.

3. Article 15: non-discrimination and educational inclusion

Article 15(1) prohibits the State from discriminating against citizens on grounds only of religion, race, caste, sex or place of birth. Residence is not listed here. Article 15(2) prohibits disabilities on these grounds regarding access to shops, public restaurants, hotels and places of public entertainment, and use of specified public facilities such as wells, roads and bathing ghats maintained from State funds or dedicated to public use.

Article 15(3) permits special provisions for women and children. Article 15(4), inserted by the First Amendment in 1951 after State of Madras v. Champakam Dorairajan, enables special provisions for socially and educationally backward classes and for Scheduled Castes and Scheduled Tribes. Article 15(5), inserted by the 93rd Amendment, enables admission-related special provisions for these groups in educational institutions, including private aided and unaided institutions, but excludes minority educational institutions protected by Article 30(1).

Article 15(6), inserted by the 103rd Amendment, enables special provisions for economically weaker sections other than the classes covered by Articles 15(4) and 15(5). Its educational reservation provision permits up to 10 per cent additional reservation, including in private aided and unaided institutions, with the same minority-institution exclusion. Janhit Abhiyan v. Union of India (2022) upheld the amendment by a 3:2 majority.

4. Article 16: public employment and reservations

Article 16 guarantees citizens equality of opportunity in employment or appointment under the State. Its prohibited grounds include descent and residence, alongside religion, race, caste, sex and place of birth. Under Article 16(3), Parliament, rather than a State legislature acting under this clause, may prescribe residence requirements for specified public employment. Article 16(5) preserves certain religion-related requirements for offices connected with religious or denominational institutions.

Article 16(4) enables reservation for a backward class of citizens that, in the State's opinion, is inadequately represented in State services. In Indra Sawhney v. Union of India (1992), the Supreme Court upheld OBC reservation, required exclusion of the creamy layer among OBCs, and ordinarily limited reservations to 50 per cent. It also held that Article 16(4) did not authorise reservation in promotion. The case arose from measures implementing the Mandal Commission's recommendations.

The 77th Amendment inserted Article 16(4A), enabling reservation in promotion for SCs and STs where inadequately represented. The 85th Amendment added consequential seniority. Article 16(4B), introduced by the 81st Amendment, treats qualifying backlog vacancies separately for the constitutional calculation of the 50 per cent ceiling on current-year vacancies. Article 16(6) separately enables up to 10 per cent EWS reservation in appointments or posts.

M. Nagaraj v. Union of India (2006) required constitutional safeguards for promotion reservations, including data on inadequate representation and attention to administrative efficiency under Article 335. Jarnail Singh v. Lachhmi Narain Gupta (2018) removed the requirement to collect data demonstrating backwardness of SCs and STs, but retained the inadequate-representation requirement. Reservation provisions are enabling: they do not automatically create a fundamental right to demand a reservation policy.

5. Articles 17–18 and the wider equality framework

Article 17 abolishes untouchability and forbids its practice in any form. The term concerns the historically rooted social practice, not every instance of social avoidance. Parliament enacted the Protection of Civil Rights Act, 1955 to penalise enforcement of disabilities arising from untouchability. The Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989 provides additional protection against specified atrocities. Article 35 assigns Parliament legislative competence to prescribe punishment for acts declared offences under Part III.

Article 18 prohibits the State from conferring titles except military or academic distinctions. Indian citizens cannot accept titles from foreign States. Separate restrictions govern foreign titles, presents, emoluments and offices for specified persons holding offices of profit or trust under the State. In Balaji Raghavan v. Union of India (1995), the Supreme Court upheld national awards such as Bharat Ratna and Padma awards, provided they are not used as prefixes or suffixes.

Equality also informs Fundamental Duties: Article 51A(e) calls for harmony across diversities and renunciation of practices derogatory to women's dignity. Duties do not override enforceable rights. In State of Punjab v. Davinder Singh (2024), a seven-judge Bench permitted evidence-based sub-classification within Scheduled Castes for reservation benefits, overruling E. V. Chinnaiah. States cannot alter the Presidential List under Article 341, and sub-classification remains subject to judicial review.

• For problem questions, first identify the actor, protected group, prohibited ground and relevant exception.
• Do not transfer every rule governing OBC, SC/ST and EWS reservations indiscriminately across categories.
