UPSC Syllabus: GS Paper-2- Governance

Context: Delimitation refers to the process of fixing the number of seats and boundaries of territorial constituencies for the Lok Sabha and State Legislative Assemblies. It ensures fair political representation based on population and supports the democratic principle of one citizen–one vote–one value.

Existing Constitutional Provisions on Delimitation

1. Delimitation is carried out by a Delimitation Commission constituted through an Act of Parliament.
2. Past delimitation exercises were conducted based on the 1951, 1961, and 1971 Census.
3. The number of Lok Sabha seats was fixed at 543 seats based on the 1971 Census population of about 54.8 crore.
4. The delimitation process was frozen to encourage population control measures across States.
5. As per constitutional provisions, the next readjustment of seats is to be undertaken after the 2027 Census.

Key Provisions of the Proposed 131st Constitutional Amendment Bill

1. The Bill proposed to increase the maximum strength of the Lok Sabha from 550 to 850 seats.
2. It proposed that seat allocation across States be based on the latest Census figures after delimitation.
3. It proposed to delink one-third reservation for women from the next Census and enable implementation based on delimitation using the 2011 Census.

Provisions of the Delimitation Bill, 2026

1. The Bill proposed the constitution of a Delimitation Commission by the Union government.
2. The Commission would allocate Lok Sabha seats among States and Union Territories based on the latest available Census figures.
3. If implemented immediately, the allocation would have been based on the 2011 Census.

Government’s Rationale for Increasing Lok Sabha Seats

1. The government argued that increasing seats by about 50% would enable the smoother implementation of one-third reservation for women.
2. It was suggested that each State and Union Territory would receive a 50% pro-rata increase in seats without altering their proportional representation.

Concerns Raised by the Opposition

1. The Opposition argued that there was no immediate need to bundle women’s reservation with delimitation.
2. The Bill did not contain an explicit constitutional guarantee for a 50% pro-rata increase in seats for each State and Union Territory.
3. There were concerns that delimitation based on population changes could alter the federal balance of representation.
4. It was argued that such a sensitive issue required wider consultation and detailed parliamentary scrutiny rather than passage in a short session.

Key Constitutional Issue: One Citizen–One Vote vs Federal Balance

1. Article 81(2) of the Constitution provides that the ratio between population and seats across States should be maintained as far as practicable.
2. Population growth variations across States since 1971 create tensions between democratic equality and federal fairness.
3. States that successfully controlled population growth may face reduced representation relative to high-growth States.

Way Forward

1. Delimitation reforms should balance democratic equality with federal principles.
2. A wider political consensus should be developed through parliamentary committees.
3. A pro-rata seat increase mechanism may be considered to maintain inter-State representation balance.
4. Strengthening representation in Panchayats and Municipalities can improve grassroots democratic participation.

Conclusion: Delimitation is essential for maintaining representative democracy, but must be implemented carefully to preserve India’s federal structure and political balance. A consultative and transparent approach will ensure legitimacy and acceptance of future delimitation reforms.

Question: Discuss the constitutional framework, recent proposals, and challenges associated with the delimitation of parliamentary constituencies in India. Suggest a balanced way forward.
