What Happened

The Economic Advisory Council to the Prime Minister (EAC-PM) released a working paper recommending that India increase Lok Sabha constituencies from 543 to 824 by splitting 170 large constituencies rather than undertaking a comprehensive redraw.
The study recommends 59 two-way splits and 111 three-way splits, targeting constituencies where large population size suppresses voter turnout.
Proposed seat increases by state include: Uttar Pradesh (80→120), Bihar (40→60), Maharashtra (48→72), Tamil Nadu (39→59), Karnataka (28→42), Kerala (20→30), and Andhra Pradesh (25→38).
The paper pairs delimitation with measures to raise women voter turnout: women-only polling booths in metropolitan areas, extended evening polling hours, transport assistance, and voter registration drives via Anganwadi and ASHA networks.
The analysis is based on data from 2,171 constituency-elections across four general elections (2009–2024), examining how constituency size, urban share, SC/ST composition, and linguistic diversity affect turnout.
The Constitution (131st Amendment) Bill, 2026, which sought to expand Lok Sabha to 850 seats and operationalise women's reservation, failed on 17 April 2026 in the Lok Sabha (298 votes in favour, 230 against — short of the two-thirds special majority required under Article 368).

Static Topic Bridges

Article 81 and 82 — Composition of Lok Sabha and Readjustment After Census

Article 81 of the Constitution requires that the allocation of Lok Sabha seats to each state be proportionate to its population, with the ratio between constituency population and seats being "so far as practicable, the same for all states." Article 82 mandates that after every census, Parliament must enact a law to readjust (delimit) constituency boundaries and seat allocations through a Delimitation Commission.

Article 81(1)(a): Maximum 550 elected seats in Lok Sabha (currently 543 filled).
Article 82: Readjustment to occur after each census — Parliament determines the authority and method.
42nd Constitutional Amendment (1976): Froze total Lok Sabha and state assembly seats based on the 1971 census — a measure to avoid penalising states that reduced population growth.
84th Constitutional Amendment (2001): Extended the freeze until after the first census post-2026, i.e., the 2031 census.
The current EAC-PM proposal is aimed at managing representation deficits while the formal freeze remains operative pending legislative change.

Connection to this news: The EAC-PM study proposes a targeted legislative route — splitting constituencies without waiting for a full post-census delimitation — to address the representation gap created by decades of the seat freeze.

Delimitation Commission — Composition, Powers, and Process

A Delimitation Commission is a statutory body constituted under the Delimitation Commission Act. Its orders have the force of law and cannot be questioned in any court. The commission is headed by a retired Supreme Court judge, with the Chief Election Commissioner and State Election Commissioners as ex-officio members.

Four Delimitation Commissions constituted so far: 1952, 1963, 1973, and 2002.
The 2002 Commission (Justice Kuldip Singh) used the 2001 census; its orders took effect in 2008.
The Delimitation Bill, 2026 (introduced April 16) sought to enable delimitation based on the 2011 census before the 2031 census is published — a departure from the usual post-census trigger.
Delimitation orders are binding and published in the Gazette; they override state laws and cannot be challenged in court (Article 329).

Connection to this news: The EAC-PM working paper feeds into the ongoing legislative effort to restart delimitation, proposing a phased constituency-split model as an intermediate option after the constitutional amendment route failed.

Article 368 — Special Majority for Constitutional Amendments

Article 368 provides the procedure for amending the Constitution. Amendments that change the representation of states in Parliament require a special majority: two-thirds of members present and voting in each House, and this majority must also constitute more than half of the total membership of the House.

Special majority = at least 2/3 of members present and voting AND majority of total House membership.
Simple majority (>50% of members present and voting) suffices for ordinary legislation.
Effective majority = more than 50% of the total membership of the House (used for removal of certain constitutional functionaries).
The 131st Amendment Bill received 298/528 votes (56.4%) — clearing a simple majority but falling 54 votes short of the two-thirds threshold.

Connection to this news: The failed April 2026 vote illustrates the high constitutional threshold for increasing Lok Sabha seats, which is why the EAC-PM study explores an alternative targeted-split approach that may require only ordinary legislation rather than a constitutional amendment.

Women's Reservation in Parliament — 106th Constitutional Amendment

The 106th Constitutional Amendment (Nari Shakti Vandan Adhiniyam), enacted in September 2023, inserts Article 330A and 332A into the Constitution, reserving one-third of Lok Sabha and state assembly seats for women. The reservation is contingent on delimitation based on a fresh census.

Reservation applies to general seats and SC/ST reserved seats proportionally.
Will take effect only after delimitation following the first census after the Act's commencement — linking women's reservation activation to completion of delimitation.
Duration of reservation: 15 years from commencement, renewable by Parliament.
The 2026 delimitation bills sought to operationalise this reservation ahead of a post-2031 census.

Connection to this news: The EAC-PM paper proposes pairing its targeted constituency-split model with women voter-turnout measures as an interim step, pending the formal activation of reservation seats through delimitation.
