Background and Context

The Constitution (131st Amendment) Bill, 2026 was introduced to accelerate the implementation of the 106th Constitutional Amendment (2023), also known as the Nari Shakti Vandan Adhiniyam, which provides 33% reservation for women in Lok Sabha and State Assemblies. This amendment came into force on 16th April 2026, but its actual implementation remained deferred due to Article 334A, which links women's reservation to a delimitation exercise after the next Census (post-2027).

The Delimitation Freeze

  • The freeze on parliamentary constituency boundaries began with the 42nd Constitutional Amendment (1976), based on the 1971 Census
  • Originally intended to continue until the first Census after 2000
  • Later extended by the 84th Constitutional Amendment (2001) until the first Census after 2026
  • The Bill sought to end this freeze using the 2011 Census to restore "one person, one vote, one value"

Voting and Failure

  • Total House strength: 528 members
  • Votes received: 298
  • Required for special majority: 352 (majority of total membership + 2/3 of members present and voting)
  • The Bill failed to achieve the special majority as per Article 368 of the Indian Constitution

Withdrawn Allied Legislation

Due to the collapse of the constitutional amendment bill, two dependent bills were immediately withdrawn:

  1. Union Territories Laws (Amendment) Bill, 2026
  2. Delimitation Bill, 2026

Federalism Debate: North-South Divide

The primary legislative roadblock was the demographic disparity between states:

  • Opposition argument: Population-based delimitation would penalize Southern states that have achieved effective population control
  • Demand: Complete delinking of women's reservation from the delimitation exercise
  • Southern states feared losing parliamentary representation due to lower population growth compared to Northern states

Constitutional Provisions

  • Article 368: Deals with Parliament's power to amend the Constitution and the special majority requirement
  • Article 334A: Introduced by Nari Shakti Vandan Adhiniyam, mandates that women's reservation shall be effective after delimitation is done based on the first census after 2027
