Reservation is a system of positive discrimination in which a fixed share of seats in education, public jobs and sometimes legislatures is set aside for groups that have faced social, educational or economic disadvantage. It is a constitutional tool to achieve real equality, and not just formal equality, in a society with deep caste-based inequalities. Reservation is one of the most discussed topics in Social Justice (GS Paper 2) in the UPSC Civil Services Examination. Prelims asks about Articles, amendments and judgments, and Mains asks about its need, merits, problems and reforms. This note explains reservation in India in simple language, with a timeline and the latest developments.

Why Reservation? Philosophy and Need

For centuries, Indian society was divided by the caste system, with Scheduled Castes (SCs) subjected to untouchability and Scheduled Tribes (STs) isolated and exploited. Simply declaring equality in law was not enough to bring them into schools, offices and governance. Reservation therefore aims to give fair representation, to improve the social and economic status of the disadvantaged, to break stereotypes and to build an inclusive democracy. It is based on the idea of substantive equality and on social justice in the Preamble. Dr. B. R. Ambedkar defended it as a temporary measure to ensure that all communities get a share in power, and the Poona Pact of 1932 between Gandhi and Ambedkar gave reserved seats to the depressed classes in the legislatures instead of separate electorates.

Historical Background

Reservation began even before independence. In 1902, the ruler of Kolhapur, Chhatrapati Shahu Maharaj, reserved 50 percent of jobs for backward classes. In 1921, Mysore and Madras Presidency introduced reservations. The Government of India Act, 1935 used the term "Scheduled Castes". After independence, the Constitution gave reservations for SCs and STs (15 percent and 7.5 percent in central jobs). The Kaka Kalelkar Commission (1953) was the first Backward Classes Commission, but its report was not accepted. The Mandal Commission (1979, headed by B. P. Mandal) identified 3,743 castes as socially and educationally backward, recommended 27 percent reservation for OBCs, and the government of V. P. Singh implemented it in public jobs in 1990. In 1993, OBC reservation started, and in 2006, 27 percent OBC reservation was introduced in central higher educational institutions.

Landmark Judgments

In the State of Madras v. Champakam Dorairajan (1951), the Supreme Court struck down caste-based reservation in education, which led to the First Amendment. The most important judgment is Indra Sawhney v. Union of India (1992), also known as the Mandal case. The Court upheld 27 percent OBC reservation but laid down key rules: the total reservation should not exceed 50 percent (except in extraordinary situations), the creamy layer among OBCs must be excluded, there should be no reservation in promotions, and reservation applies only at the stage of initial appointment. Parliament overcame the promotion issue through the 77th Amendment. In M. Nagaraj (2006), the Court upheld the promotion provision but asked for quantifiable data on backwardness, inadequacy of representation and efficiency. In Janhit Abhiyan (2022), a five-judge bench upheld the 10 percent EWS quota by a 3:2 majority. In the Maratha reservation case (2021), the Court struck down the quota because it crossed the 50 percent limit and no extraordinary situation was shown. In State of Punjab v. Davinder Singh (2024), a seven-judge bench ruled that States can sub-classify Scheduled Castes to give more benefit to the most backward within them, and it also said the creamy layer principle should be considered for SCs and STs.

Present Reservation Structure

At the central level, reservation in jobs and admission is 15 percent for SCs, 7.5 percent for STs, 27 percent for OBCs and 10 percent for EWS, which adds up to about 59.5 percent. States have their own quotas, and some, like Tamil Nadu (69 percent, protected in the Ninth Schedule), exceed 50 percent. The creamy layer for OBCs is set by an income limit (currently 8 lakh rupees per year, and a revision is pending) and by status criteria. The Nari Shakti Vandan Adhiniyam (106th Amendment), 2023 reserves one-third of the seats in the Lok Sabha and State Assemblies for women, to be implemented after the next census and delimitation. The government has also decided to include caste enumeration in the upcoming national census.

Arguments For and Against

In favour: it corrects historical injustice, increases representation, reduces inequality and discrimination, and builds a diverse administration that understands the problems of weaker sections. Studies show that it has created a middle class among SCs and STs. Against: benefits are cornered by the better-off within the groups (the creamy layer), the poorest within the group are left out, it may deepen caste identity, there are claims it harms merit and efficiency, and the demand for quotas by dominant groups like Jats, Patidars and Marathas creates political pressure. Many experts say that reservation is necessary but not sufficient; it must be paired with quality education, nutrition, skill-building and job creation, because the number of government jobs is limited.

Reforms and Way Forward

Suggestions include strict implementation of the creamy layer principle; sub-categorisation of OBCs (as examined by the Rohini Commission) and of SCs to ensure that the most backward benefit; use of data from a caste census to design policy scientifically; a periodic review of the lists; more focus on education at early stages, scholarships and coaching; skill training and entrepreneurship support, such as Stand-Up India; and strong action against discrimination. Reservation should be seen as one tool, not the only tool, in a broader plan for social justice and inclusive growth.

Reservation for Women, Persons With Disabilities and Others

Besides caste-based reservation, other forms of positive action exist. Women have one-third reservation in Panchayats and municipalities (and many states give 50 percent), and a similar reservation for Parliament and State Assemblies has been legislated. The Rights of Persons with Disabilities Act, 2016 provides 4 percent reservation in government jobs for persons with benchmark disabilities and 5 percent in higher education. Ex-servicemen get a share of posts, and some states give domicile-based or local preference in jobs, which the courts examine carefully under Article 16(2). Reservation in private sector jobs, as attempted by some states, remains debated, because of questions on freedom of business and efficiency. These examples show that the idea of reservation has grown from caste to a wider notion of inclusion.

Horizontal and Vertical Reservation

A common Prelims confusion is between vertical and horizontal reservation. Vertical reservation is the reservation for the classes specified in the Constitution, such as SC, ST, OBC and EWS. Horizontal reservation cuts across all categories, for groups like women, persons with disabilities and ex-servicemen. For instance, if 3 percent is reserved for persons with disabilities horizontally, those seats are filled from within each vertical category, so an SC candidate with disability will be counted in both SC and disability groups. The Supreme Court explained this in the Indra Sawhney and later cases. Knowing this difference helps you answer questions on how seats are filled after the merit list and the quota lists are prepared.

Role of the National Commissions

Several commissions work to protect the rights of backward groups. The National Commission for Scheduled Castes (Article 338), the National Commission for Scheduled Tribes (Article 338A) and the National Commission for Backward Classes (a constitutional body since the 102nd Amendment, Article 338B) look into complaints, monitor safeguards and advise the government. State commissions and the Ministry of Social Justice and Empowerment support them. A strong and independent commission, with powers and data, is necessary to make sure that reservation reaches the right people.
