Constitution 131st Amendment Bill (Delimitation) Negatived in Lok Sabha — CLAT 2027

CURRENT AFFAIRS | MAY 5, 2026

The Lok Sabha on 5 May 2026 negatived the Constitution (One Hundred and Thirty-First Amendment) Bill — a measure that sought to lift the long-standing freeze on Lok Sabha seat reallocation following the post-2026 census. The Bill failed to muster the special majority required under Article 368(2), reigniting one of the most consequential federal debates in Indian constitutional law: how to balance population-based representation against the equity claims of demographically restrained states.

What Happened

The Bill was put to vote and rejected. Under parliamentary procedure, “negatived” denotes a bill that has been put to a division and failed to secure the requisite majority — in this case, the special majority under Article 368(2): two-thirds of those present and voting and more than half of the total membership of each House. Ordinarily, a bill so negatived cannot be reintroduced in the same session.

🏛️ Constitutional Framework

Article 82 mandates the readjustment of Lok Sabha seats among states upon completion of each census, by an authority and in such manner as Parliament may by law determine. Article 170 contains the parallel provision for Legislative Assemblies. Article 81 caps the Lok Sabha at 550 elected members (530 from states + 20 from UTs). Article 368 prescribes the special majority procedure for amending these provisions.

The 42nd Constitutional Amendment Act, 1976 first froze the population-based readjustment till the first census after 2000 (i.e., the 2001 census). The 84th Constitutional Amendment Act, 2001 extended that freeze till the first census taken after the year 2026 — the wall the 131st Amendment Bill sought to dismantle.

This single news item is a treasure trove for CLAT 2027 Legal Reasoning and GK passages. Expect questions on: (i) Article 368 majority math — the trifecta of simple, special, and special-plus-state-ratification majorities; (ii) the 42nd vs 84th Amendment timeline; (iii) whether delimitation matters fall within the basic structure (the SC has not held so but federalism does); (iv) the role of the Delimitation Commission (statutory, not constitutional) and the bar under Article 329 on judicial review of its orders; (v) the federal-equity tension between south and north India.

📊 Key Facts at a Glance

Item Detail
Bill Constitution (131st Amendment) Bill
Status Negatived in Lok Sabha
Operative Articles Articles 82 & 170 (delimitation), 81 (composition), 368 (amendment)
Majority Required Special majority — 2/3 present & voting + >50% total membership
Earlier Freeze 42nd Amendment 1976 (till 2001 census); 84th Amendment 2001 (till first census after 2026)
Judicial Review Article 329 — delimitation orders not justiciable

🧠 Mnemonic — “82-170-368, F-2026”

F-2026 = the Freeze runs till the first census after 2026. 82-170-368 = the three article triad — Article 82 (Lok Sabha readjustment), Article 170 (Assembly composition), Article 368 (amendment procedure). Remember: “Eight-Two reads the People; One-Seventy reads the State; Three-Six-Eight rewrites them both.”

Quick answers

The Constitution 131st Amendment Bill, which sought to lift the freeze on Lok Sabha seat reallocation, primarily relates to which constitutional articles?
Articles 82 & 170. Article 82 deals with readjustment after each census of Lok Sabha seats; Article 170 deals with composition of Legislative Assemblies. Both are the operative provisions for delimitation.
Under Article 368(2), a Constitutional Amendment Bill of this nature requires:
Special majority — 2/3 of those present and voting AND >50% of total membership. Article 368(2) requires the special majority — 2/3 of members present and voting plus more than 50% of the total membership of each House. The 131st Amendment Bill was 'negatived' because it failed this threshold.
The 42nd Constitutional Amendment Act, 1976, in the context of delimitation, did what?
First froze Lok Sabha and Assembly seat allocation till the 2001 census. The 42nd Amendment 1976 first froze the readjustment of seat allocation till the first census after 2000 (i.e., the 2001 census), to preserve the existing balance among states.
The 84th Constitutional Amendment Act, 2001, extended the freeze on seat reallocation till:
The first census after 2026. The 84th Amendment 2001 extended the population-based seat reallocation freeze till the first census taken after the year 2026.
'Negatived' in parliamentary procedure means a bill:
Was put to vote and rejected by the House. A bill is 'negatived' when on being put to vote, it does not secure the requisite majority and is therefore rejected by the House.
Which body conducts delimitation in India?
The Delimitation Commission established by an Act of Parliament. Delimitation is carried out by a Delimitation Commission constituted under a Delimitation Act passed by Parliament. Its orders cannot be questioned in any court (Article 329).
