Reservation in Legislature — Basic Structure

Basic Structure

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.

Important Differences

vs Reservation in Services

Aspect	This Topic	Reservation in Services
Constitutional Basis	Articles 330, 332, 334 (for Lok Sabha & State Assemblies); Articles 243D, 243T (for Local Bodies)	Articles 16(4), 16(4A), 16(4B), 335 (for Public Employment)
Purpose	Political empowerment, ensuring representation in law-making bodies, fostering inclusive democracy.	Ensuring adequate representation of backward classes in government services, addressing historical discrimination in employment.
Beneficiaries	Scheduled Castes (SCs), Scheduled Tribes (STs), and Women (in local bodies).	Scheduled Castes (SCs), Scheduled Tribes (STs), Other Backward Classes (OBCs), Economically Weaker Sections (EWS).
Mechanism	Reserved Constituencies: Only SC/ST candidates can contest, but all voters participate. Population-based proportionality.	Reserved Posts: Specific percentage of government jobs/promotions earmarked for reserved categories. Merit-based selection within quota.
Creamy Layer	Generally not applicable to legislative reservation due to population-based nature and joint electorate.	Applicable to OBCs (Indra Sawhney) and judicially extended to SC/STs in promotions (Jarnail Singh).
Time Limit	Initially 10 years, repeatedly extended (currently till 2030 by 104th CA).	No specific time limit mentioned in the Constitution for services, but subject to review of 'adequacy of representation'.
Judicial Scrutiny Focus	Primarily on delimitation process, fairness of seat allocation, and constitutional validity of extensions.	Focus on 50% cap, creamy layer, quantifiable data for backwardness/inadequacy, and impact on administrative efficiency.

The fundamental difference between reservation in legislature and reservation in services lies in their primary objective and operational mechanism. Legislative reservation, governed by Articles 330, 332, and 334, aims at political empowerment by ensuring direct representation of Scheduled Castes and Scheduled Tribes in law-making bodies through reserved constituencies. Its basis is population proportionality, and it has a time-bound constitutional mandate, repeatedly extended. In contrast, reservation in services, under Articles 16(4), 16(4A), and 16(4B), focuses on ensuring adequate representation of various backward classes (SCs, STs, OBCs, EWS) in public employment. This involves earmarking a percentage of government jobs and promotions. While legislative reservation typically doesn't apply the 'creamy layer' concept, it is a crucial aspect of service reservation for OBCs and, by judicial pronouncement, for SC/STs in promotions. Both are affirmative action tools, but their constitutional underpinnings, beneficiaries, and implementation challenges diverge significantly, reflecting distinct goals of social justice.

vs Article 330 and Article 332

Aspect	This Topic	Article 330 and Article 332
Scope of Application	Applies to the House of the People (Lok Sabha), the lower house of the Union Parliament.	Applies to the Legislative Assemblies of the States, the lower house of state legislatures.
Body Represented	Ensures representation at the national level.	Ensures representation at the state level.
Total Seats Involved	Currently, 543 Lok Sabha seats (84 SC, 47 ST reserved).	Varies by state (e.g., Uttar Pradesh Assembly has 403 seats, with specific SC/ST reservations).
Determining Authority	Delimitation Commission, based on national population data for states/UTs.	Delimitation Commission, based on state-specific population data.
Constitutional Article Number	Article 330	Article 332

Articles 330 and 332 are twin provisions that extend the principle of legislative reservation for Scheduled Castes and Scheduled Tribes across different tiers of India's democratic structure. Article 330 specifically deals with the reservation of seats in the Lok Sabha, the national Parliament, ensuring that SCs and STs have a voice in central law-making. Article 332, on the other hand, applies this same principle to the State Legislative Assemblies, guaranteeing their representation in state-level policy formulation. While both articles operate on the fundamental principle of reserving seats in proportion to the population of these communities, their distinct application to the Union and State legislatures highlights the comprehensive approach of the Constitution to ensure political inclusion at all significant elected levels of governance. The mechanism of determining reserved seats through the Delimitation Commission remains common to both.
