The Union government has introduced a comprehensive legislative package, including the , to initiate a fresh delimitation exercise based on the latest Census figures. This move aims to expand the Lok Sabha's capacity to 850 members and trigger the implementation of the one-third women's reservation in legislative bodies.
The legislative package directly alters the constitutional framework governing parliamentary representation. Currently, Article 81 and Article 82 freeze Lok Sabha seat allocation across states based on the 1971 Census to incentivize population control, a freeze that was originally intended to last until the first Census post-2026. The new Constitution (One Hundred and Thirty-First Amendment) Bill, 2026 removes this rigid timeline, paving the way for representation based on the 'latest published census figures' notified by Parliament. It fundamentally alters the composition of the Lower House by raising its maximum strength to 850 (815 from states, 35 from Union Territories). For UPSC Prelims, aspirants must note the specific changes to the marginal headings and clauses of Article 82, which shift the constitutional focus from post-Census readjustment to a more generalized framework of constituency readjustment.
The accompanying Delimitation Bill, 2026, establishes the institutional machinery for seat reallocation and boundary drawing. It mandates the creation of a Delimitation Commission, an independent body historically headed by a retired or sitting Supreme Court judge, and including the Chief Election Commissioner and State Election Commissioners. This body is vested with the powers of a civil court, and its primary task is to redraw constituency boundaries ensuring geographic compactness while accommodating administrative units. Crucially for UPSC Mains, the orders of this Commission carry the force of law and cannot be challenged in any court. This finality is designed to prevent endless electoral litigation and delays, but it frequently raises academic debates regarding the limits of judicial review in India's democratic process.
The upcoming delimitation exercise introduces a severe test for Indian federalism, commonly referred to as the 'North-South divide'. States in Southern India, which successfully curbed population growth over the past five decades, fear reduced political representation compared to Hindi heartland states with historically higher fertility rates. Balancing democratic proportionality (one person, one vote) with federal equity will be the Commission's greatest challenge, though the government has promised to maintain current proportional state shares via a new formula. Conversely, the exercise acts as a watershed moment for social justice, as it serves as the constitutional trigger for the Constitution (One Hundred and Sixth Amendment) Act, 2023 (Nari Shakti Vandan Adhiniyam). This guarantees a 15-year, one-third reservation for women across the Lok Sabha and State Assemblies, fundamentally altering grassroots candidate selection, dismantling entrenched political strongholds, and reshaping coalition arithmetic.
