Constitutional Basis of Reservation in India

Reservation constitutional basis in India rests chiefly on Articles 15 and 16 of the Constitution, which permit the State to depart from formal equality in order to secure genuine equality for groups that have historically faced social and educational disadvantage. These provisions sit alongside political-reservation clauses such as Articles 330 and 332, together forming a constitutional scheme of affirmative action that predates comparable civil-rights legislation in several other democracies, including the United States, where the Civil Rights Act came only in 1964. Over the decades, this scheme has been shaped as much by judicial interpretation and constitutional amendment as by the original text itself.

Article 15: Reservation in Education and Public Life

Article 15 begins by prohibiting discrimination by the State against any citizen on grounds such as religion, race, caste, sex, or place of birth. But the same Article also carries a set of enabling clauses that authorise the State to make special provisions for disadvantaged groups, so that formal non-discrimination does not freeze existing inequality in place. Read together, these clauses allow the State to:

• Reserve seats or offer fee concessions in public educational institutions for weaker sections.
• Make special provision for the advancement of socially and educationally backward classes (SEBCs) and Scheduled Castes and Scheduled Tribes with regard to admission to educational institutions — a power that extends to private institutions, whether aided or unaided by the State, though minority educational institutions are excluded from this requirement. This clause was inserted through the 93rd Constitutional Amendment Act of 2005. To operationalise it for centrally run institutions, Parliament enacted the Central Educational Institutions (Reservation in Admission) Act, 2006, which set a 27% admission quota for Other Backward Classes (OBCs).
• Make special provision for the advancement of economically weaker sections (EWS), including reservation of up to 10% of seats in educational institutions — again covering private aided and unaided institutions, excluding minority institutions. This EWS quota operates in addition to existing caste-based reservations, with eligibility determined by the State from time to time on the basis of family income and other indicators of economic disadvantage.

Article 16: Reservation in Public Employment

Article 16 guarantees equality of opportunity in matters of public employment. Its clause (4) is the specific enabling provision for job reservation: it allows the State to reserve appointments or posts for any backward class of citizens that, in the State's opinion, is not adequately represented in the services under it. This clause became the constitutional anchor for OBC reservation in government jobs and has since been the subject of extensive litigation over its scope, particularly on whether it also covers promotions and how far the reservation quantum can extend.

Legislative responses over the years have progressively expanded the reach of Article 16(4). A sequence of constitutional amendments addressed specific gaps that arose from judicial rulings restricting reservation in promotions and backlog vacancies:

Political Reservation: Articles 330 and 332

Beyond education and employment, the Constitution also builds reservation into political representation. Articles 330 and 332 reserve seats for Scheduled Castes and Scheduled Tribes in the Lok Sabha and in the State Legislative Assemblies respectively, ensuring these communities have guaranteed representation in elected law-making bodies rather than relying solely on general electoral outcomes.

The Indra Sawhney Case: Defining the Limits

The Supreme Court's 1992 ruling in the Indra Sawhney case (popularly called the Mandal case) remains the most significant judicial statement on the scope of Article 16(4). The Court upheld the government's executive order granting 27% reservation in jobs to OBCs, but attached important conditions that continue to govern reservation policy:

• The "creamy layer" among OBCs must be excluded from the benefit of reservation.
• Reservation in promotions was not permitted under Article 16(4) as originally interpreted (this position was later modified through the 77th and subsequent amendments).
• Total reservation should not ordinarily exceed 50% of available posts.
• A ceiling of 50% also applies to reservation in backlog (carried-forward) vacancies.
• No relaxation in qualifying marks was to be allowed for promotions.

The judgment simultaneously struck down a separate executive order that had proposed an additional 10% reservation for economically backward sections not otherwise covered by existing OBC schemes, holding that reservation under Article 16(4) was meant for backward classes and not for economic criteria alone at that time. The ruling's aftermath included the appointment of a committee to identify the creamy layer among OBCs and the establishment of a statutory National Commission for Backward Classes to examine complaints about inclusion or exclusion of communities from the OBC list.

Extending the Framework: The NALSA Judgment

The constitutional basis of reservation has not remained confined to caste alone. In the 2014 National Legal Services Authority (NALSA) case, the Supreme Court recognised transgender persons as a distinct "third gender" and held that the fundamental rights under Part III of the Constitution, including Articles 14 and 21, apply equally to them. The Court directed the Central and State Governments to treat transgender persons as a socially and educationally backward class and to extend reservation benefits to them in education and public appointments. This judgment eventually led to the enactment of the Transgender Persons (Protection of Rights) Act, 2019, which prohibits discrimination against transgender persons and recognises their right to self-perceived gender identity.

UPSC Relevance

Prelims

• Know the specific clauses: Article 15(4)/(5) for education, Article 16(4) for public employment, Articles 330/332 for legislative seats.
• Remember the 50% ceiling on reservation laid down in the Indra Sawhney case and the amendments that modified its application to promotions and backlog vacancies.
• Note the year and effect of the 93rd Amendment (2005) and the Central Educational Institutions (Reservation in Admission) Act, 2006.

Mains

• Discuss how judicial interpretation (Indra Sawhney, NALSA) has shaped the constitutional scheme of reservation beyond the bare text of Articles 15 and 16.
• Examine the tension between the 50% ceiling principle and subsequent reservation expansions, including EWS reservation.
• Analyse how reservation has evolved from a caste-based affirmative action tool to one covering economic and gender-identity criteria.

FAQ

Q1. Which Articles form the constitutional basis of reservation in India? Primarily Articles 15 (education and social provisions) and 16 (public employment), supplemented by Articles 330 and 332 for reserved seats in legislatures.

Q2. What did the Indra Sawhney case decide? It upheld 27% OBC reservation in jobs under Article 16(4), while laying down conditions such as creamy-layer exclusion and a general 50% ceiling on total reservation.

Q3. How is EWS reservation different from SC/ST/OBC reservation? EWS reservation under Article 15 is based on economic criteria and family income, applies additionally to existing caste-based quotas, and is capped at 10% of seats.

Q4. What did the NALSA judgment add to the reservation framework? It directed governments to treat transgender persons as a socially and educationally backward class and extend reservation to them in education and public employment.

Q5. Does Article 15 reservation apply to private institutions? Yes, since the 93rd Amendment, it extends to private educational institutions, whether aided or unaided by the State, except minority educational institutions.
