Ashoka Kumar Thakur v. Union of India

The story

When Parliament amended the Constitution in 2005 to allow reservations for OBCs in higher education, and followed it with a law reserving 27% seats in institutions like IITs and IIMs, it sparked fierce debate. Ashoka Kumar Thakur, a public-spirited litigant, challenged this before the Supreme Court, arguing it violated equality and threatened merit-based admissions. Students, academics, and policymakers watched closely, as the outcome would decide the fate of hundreds of thousands of aspiring engineers, doctors, and managers from backward communities. The five-judge bench grappled with balancing social justice against equality of opportunity. In a landmark 2008 verdict, the Court upheld the reservation policy, affirming that affirmative action for OBCs was constitutionally sound. Yet it added a crucial safeguard: the 'creamy layer'—the more privileged among OBCs—must be excluded, ensuring the policy served its true purpose of uplifting the disadvantaged. The ruling left private unaided institutions' reservation status undecided, to be fought another day. For millions of families depending on reservation to access quality education, the judgment offered both hope and a reminder that such benefits must be fairly targeted, reshaping India's ongoing debate on caste, merit, and opportunity.

The facts

Ashoka Kumar Thakur challenged the Constitution (Ninety-Third Amendment) Act, 2005 and the Central Educational Institutions (Reservation in Admission) Act, 2006, which introduced Article 15(5) and provided 27% reservation for Other Backward Classes (OBCs) in central higher educational institutions, including IITs and IIMs. The petitioner argued that the amendment and the Act violated the basic structure of the Constitution, particularly the principle of equality, and that OBC identification lacked a scientific basis. The case required the Court to examine the validity of caste-based reservation in higher education against fundamental rights under Articles 14, 15, and 19(1)(g).

The question before the court

Whether Article 15(5) and the 2006 Reservation Act, providing 27% OBC reservation in central educational institutions, violate the basic structure doctrine and the equality provisions of the Constitution, and whether the 'creamy layer' among OBCs should be excluded from such reservation.

The holding

The Supreme Court, by majority, upheld the constitutional validity of the 93rd Amendment and the Central Educational Institutions (Reservation in Admission) Act, 2006, insofar as it applied to state-maintained institutions and aided educational institutions, holding that it did not violate the basic structure of the Constitution. The Court mandated that the 'creamy layer' among OBCs must be excluded from the benefits of reservation to ensure that reservation reaches the truly disadvantaged. The Court left open the question of reservation's applicability to unaided private educational institutions, to be decided in a separate context, and directed periodic review of OBC status.

The principle it stands for

Reservation for socially and educationally backward classes in higher education is constitutionally permissible under Article 15(5) and does not violate the basic structure doctrine, provided the 'creamy layer' is excluded to ensure the benefit reaches genuinely backward sections. The equality principle under Article 14 requires that affirmative action be tailored to exclude those who have already achieved adequate social and economic advancement.

Provisions this case shaped

• Art. 15Prohibition of discrimination on grounds of religion, race, caste, sex or place of birthinterpreted — Upheld validity of Article 15(5) enabling OBC reservation in educational institutions.
• Art. 14Equality before lawinterpreted — Examined reservation policy against the equality guarantee, mandating creamy layer exclusion.
