Delimitation-Linked Women's Reservation Amendment Fails Special Majority: Implementation Pathway Unresolved
The Constitution (131st Amendment) Bill, 2026, which sought to remove the existing freeze on delimitation and enable operationalisation of the women's reservation law, failed to secure the special majority required under Article 368 when it was put to vote in the Lok Sabha on April 17, 2026
The Bill received 298 votes in favour against a requirement of at least 352 (two-thirds of members present and voting, and a majority of total House membership), falling 54 votes short
Because the Delimitation Bill, 2026 and the Union Territories Laws (Amendment) Bill, 2026 were both contingent on the constitutional amendment taking effect, both were withdrawn following the defeat
The 106th Constitutional Amendment Act, 2023 (women's reservation) remains on the statute book, but its implementation continues to depend on completion of a fresh census followed by a delimitation exercise, a sequence that remains unresolved months after the vote
Discussion has continued on the appropriate sequencing of the pending census, delimitation, and rollout of legislative reservation for women
Special Majority under Article 368: Why the Bill Failed
Article 368 of the Constitution prescribes the procedure for constitutional amendments. A Bill of this category must be passed in each House of Parliament by a "special majority": a majority of the total membership of that House, and a majority of not less than two-thirds of the members present and voting. This is a materially higher bar than the simple majority required for ordinary legislation.
The 131st Amendment Bill's failure to clear the Article 368(2) threshold — rather than any procedural irregularity — is the direct constitutional reason the linked Delimitation Bill and Union Territories Laws Bill also lapsed, since both were drafted to take effect only if the constitutional amendment passed.
Delimitation Freeze: Articles 82 and 170
Articles 82 and 170 require Parliament and State Legislatures respectively to readjust constituency boundaries and seat allocation after every census. Since 1976, however, a series of constitutional amendments has frozen this readjustment to insulate states that achieved faster population control from a corresponding loss of parliamentary seats.
The Bill's defeat leaves the pre-2026 freeze technically intact, meaning fresh delimitation of Lok Sabha and Assembly seat numbers based on updated population figures cannot yet proceed, which in turn keeps women's reservation implementation in abeyance.
106th Constitutional Amendment Act, 2023: Women's Reservation
The 106th Amendment Act, 2023 (introduced as the Nari Shakti Vandan Adhiniyam) reserves one-third of seats in the Lok Sabha, State Legislative Assemblies, and the Delhi Legislative Assembly for women, including within the reserved SC/ST quota. It received presidential assent on September 28, 2023, but Parliament wrote a specific commencement condition into the amendment itself.
Although the 2023 women's reservation law itself is validly enacted, its self-contained commencement clause means it cannot be operationalised until the census-and-delimitation sequence is completed, a sequence the failed 131st Amendment Bill was meant to unlock.
Federal Concerns in Population-Based Delimitation
A recurring constitutional debate around delimitation is that using current population as the basis for seat reallocation could shift parliamentary representation toward states with higher population growth, at the relative expense of states that achieved earlier and steeper declines in fertility rates, an equity concern the 2001 and 2003 freeze amendments were originally designed to address.
Key Details
- The population-versus-representation tension is a long-standing federalism issue also visible in Finance Commission devolution formulas, where population weightage is balanced against a "demographic performance" criterion to avoid penalising states with lower fertility
- The 84th and 87th Amendments' freeze on inter-state seat reallocation was itself a response to this concern
- Any future delimitation exercise based on updated census data would need to address the same underlying tension the freeze was designed to manage
The defeat of the 131st Amendment Bill effectively leaves this federal balancing question unresolved, since removing the freeze without an agreed formula for managing inter-state seat reallocation remains constitutionally and politically contested.
