Reservation for SC/ST/OBC/EWS under Article 15

Reservation in education under Article 15 of the Constitution is the set of exceptions that allow the State to depart from strict formal equality and make special provisions for women, children, socially and educationally backward classes, Scheduled Castes, Scheduled Tribes, and Economically Weaker Sections. What began as a single clause added in 1951 has grown, through three further amendments, into a layered framework covering both public and private educational institutions.

Why Article 15 Needed Exceptions

Article 15(1) and 15(2), as originally enacted, only prohibited discrimination — they said nothing about permitting affirmative action. This gap surfaced almost immediately: in Champakam Dorairajan v. State of Madras (1951), the Supreme Court struck down a communal quota in Madras medical and engineering colleges because Article 15 then contained no clause authorising caste-based special provisions, and a Directive Principle like Article 46 could not override a Fundamental Right. Parliament responded with the Constitution (First Amendment) Act, 1951, inserting Article 15(4). Every reservation clause added since has followed the same method — an express constitutional amendment rather than a judicially read-in exception.

The Four Layers of Article 15

Article 15(4): Backward Classes, SC and ST

Article 15(4) allows the State to make special provisions for the advancement of socially and educationally backward classes and for Scheduled Castes and Scheduled Tribes, including reservation of seats or fee concessions in public educational institutions. This clause supplies the constitutional basis for caste-based reservation in government-run colleges and universities, and it was the direct legislative answer to the vacuum exposed by the Champakam Dorairajan judgment.

Article 15(5): Reaching Private Institutions

For over five decades, reservation under Article 15(4) applied chiefly to state-run institutions. The 93rd Amendment Act of 2005 inserted Article 15(5) to extend the same principle to private educational institutions, whether or not they receive state aid — with one carve-out: minority educational institutions protected under Article 30(1) remain outside its reach. To operationalise this for central institutions, Parliament enacted the Central Educational Institutions (Reservation in Admission) Act, 2006, which set a 27% reservation quota for Other Backward Classes (OBCs) in central higher educational institutions, including the IITs and IIMs. The Supreme Court upheld the validity of both the 93rd Amendment and the 2006 Act, while directing the central government to exclude the creamy layer — the more advanced sections among OBCs — from the benefit.

Article 15(6): The EWS Addition

The Constitution (One Hundred and Third Amendment) Act, 2019 inserted Article 15(6), which came into effect on 14 January 2019. It empowers the State to make special provisions for the advancement of Economically Weaker Sections, permitting reservation of up to 10% of seats in educational institutions, over and above the existing reservations for SC, ST and OBC categories. Eligibility for EWS reservation is determined by economic criteria that the State notifies from time to time, based on family income and other indicators of economic disadvantage, and it is deliberately structured as an additional category rather than a replacement for the existing caste-based quotas.

Judicial Guardrails: Lessons from Indra Sawhney

While Indra Sawhney v. Union of India (1992) primarily concerned reservation in public employment under Article 16, the conditions it laid down have shaped how reservation is administered across the board, including in education. The Court upheld 27% OBC reservation but attached conditions: the more advanced among the backward classes — the creamy layer — must be excluded from the benefit; reservation in promotions was not then permitted; and total reservation should ordinarily not exceed 50%. These principles continue to inform how Article 15(4) and 15(5) reservations are implemented, particularly the creamy-layer exclusion for OBCs that the Supreme Court applied when upholding the 2006 central-institutions law.

UPSC Relevance

Prelims

• Article 15(3) is original to the Constitution; 15(4), 15(5) and 15(6) were each inserted by separate amendments.
• Article 15(5) excludes minority educational institutions under Article 30(1).
• EWS reservation under Article 15(6) is capped at 10% and is additional to existing SC/ST/OBC quotas.

Mains

• Examine how the exceptions under Article 15 have expanded from a narrow SC/ST/backward-class provision in 1951 to cover private institutions and economic criteria by 2019.
• Discuss the significance of the creamy-layer principle in ensuring that reservation benefits reach the intended sections.

FAQ

Q1. What is the difference between Article 15(4) and Article 15(5)? Article 15(4) permits special provisions, including reservation, for backward classes, SCs and STs generally. Article 15(5), added later, specifically extends this to admissions in private educational institutions, aided or unaided, except minority institutions under Article 30(1).

Q2. When was EWS reservation introduced and how much is reserved? The Constitution (One Hundred and Third Amendment) Act, 2019 inserted Article 15(6), effective from 14 January 2019, permitting up to 10% reservation for Economically Weaker Sections, in addition to existing SC/ST/OBC quotas.

Q3. Are minority educational institutions covered by Article 15(5)? No. Article 15(5) expressly excludes minority educational institutions protected under Article 30(1) of the Constitution.

Q4. What is the creamy layer and why does it matter? The creamy layer refers to the relatively advanced or affluent sections within backward classes. Courts have directed that they be excluded from OBC reservation benefits so that the advantage reaches the more disadvantaged members of the category.

Q5. Does Article 15 also cover reservation in public employment? No, employment reservation is governed separately by Article 16, particularly clauses 16(4) and 16(4A). Article 15 governs non-discrimination generally and reservation specifically in access to public places and educational institutions.
