The Constitution (131st Amendment) Bill, 2026, aimed at implementing women's reservation in an expanded Lok Sabha, failed to pass, delaying the delimitation process by a year.
Article 81 of the Constitution governs the delimitation of constituencies based on population figures.
The current freeze on delimitation, based on the 1971 Census for inter-state seat allocation and the 2001 Census for intra-state allocation, may lapse after the 2027 Census.
States like Kerala and Tamil Nadu may lose seats, while Uttar Pradesh, Bihar, Rajasthan, Gujarat, and Maharashtra may gain seats if delimitation reflects current population figures.
Detailed Insights:
The Atal Bihari Vajpayee government initially froze delimitation in 2001 for 25 years, using the 1971 Census to determine the inter-state distribution of seats.
Article 81(2)(a) mandates that the number of Lok Sabha seats allocated to each state should maintain a ratio proportionate to its population, as far as practicable.
Article 81(2)(b) requires states to be divided into territorial constituencies to ensure a uniform ratio between population and allocated seats within the state.
The Cabinet's December 12, 2025 press release outlined the Census exercise, with the Population Enumeration phase scheduled for February 2027, potentially providing data to trigger delimitation.
If the freeze on delimitation is not extended, the constitutional principle of one person, one vote, one value will necessitate a redistribution of seats based on the latest Census data.
Southern states may pressure the Centre to introduce a Constitutional Amendment Bill to further extend the freeze on delimitation, potentially gaining support from BJP ally TDP.
