Quick Summary

Reservation in Legislature is a constitutional mechanism in India to ensure political representation for Scheduled Castes (SCs) and Scheduled Tribes (STs) in the Lok Sabha and State Legislative Assemblies.

Rooted in the Poona Pact of 1932, this system was adopted by the Constituent Assembly to integrate marginalized communities into the political mainstream without resorting to divisive separate electorates.

Articles 330 and 332 of the Constitution mandate the reservation of seats in the Lok Sabha and State Assemblies, respectively, based on the population proportion of SCs and STs in each state or Union Territory.

The Delimitation Commission is responsible for demarcating these reserved constituencies after every census. While only SC or ST candidates can contest from these seats, all voters in the constituency participate in the election.

Article 334 initially set a ten-year limit for this reservation, but it has been repeatedly extended, most recently by the 104th Constitutional Amendment Act, 2019, until 2030. This amendment also notably ceased the provision for nominated Anglo-Indian representation.

There is no reservation in the Rajya Sabha or State Legislative Councils. The 73rd and 74th Constitutional Amendments extended reservation for SCs, STs, and women to Panchayati Raj Institutions and Urban Local Bodies, further deepening democratic inclusion.

This system aims to address historical injustices, ensure diverse voices in law-making, and strengthen India's representative democracy, though it faces ongoing debates regarding its efficacy and potential for perpetuating caste identity.
