Delimitation Reforms, 2026
- CONTEXT:The Union government has introduced three major Bills: the Constitution (One Hundred and Thirty-First Amendment) Bill, 2026, the Delimitation Bill, 2026, and the Union Territories Laws (Amendment) Bill, 2026, to enable fresh delimitation based on the latest available Census, expand the Lok Sabha, and operationalise 33% women’s reservation in legislatures.
About Delimitation
- About: Delimitation is the process of redrawing or fixing the boundaries of Lok Sabha and State Assembly constituencies so that each constituency has nearly equal population representation.
- Objective: To uphold the democratic principle of “one person, one vote, one value” by ensuring balanced representation as population changes.
Constitutional Mandate:
- Article 82: Requires Parliament to enact a Delimitation Act after every Census for readjustment of Lok Sabha seats and constituencies.
- Article 170: Provides for similar readjustment in State Legislative Assemblies.
Delimitation Commission:
- An independent statutory body appointed by the Central Government.
- Comprises:
- Chairperson (serving/retired Supreme Court Judge)
- Chief Election Commissioner (or nominee)
- State Election Commissioners of concerned States
- Its orders have the force of law, cannot be altered by Parliament or State Legislatures, and are generally final.
Freeze on Delimitation:
- 42nd Amendment Act, 1976: Froze Lok Sabha seat allocation based on the 1971 Census to protect states that successfully controlled population growth.
- 84th Amendment Act, 2001: Extended the freeze until the first Census after 2026.
- The 2002 Delimitation Commission revised only constituency boundaries using the 2001 Census, while inter-state seat allocation continued on the 1971 basis.
Judicial Review:
- In Kishorchandra Chhanganlal Rathod Case (2024), the Supreme Court ruled that Delimitation Commission orders can be reviewed only if they are manifestly arbitrary or violate constitutional principles.
About The Delimitation Bill, 2026
- The Bill operationalises the constitutional changes proposed under the Constitution (131st Amendment) Bill, 2026 by providing the framework for fresh delimitation.
New Delimitation Commission:
- Replaces the Delimitation Act, 2002.
- Authorises the Central Government to establish a new Commission headed by a Supreme Court Judge, with the Chief Election Commissioner and State Election Commissioners as members.
- The Commission will enjoy powers similar to those of a civil court.
Redrawing Constituencies:
- Responsible for reallocating seats among States and redrawing constituency boundaries using the latest published Census (currently the 2011 Census).
- Must ensure geographically compact constituencies while considering physical features, administrative boundaries, communication facilities, and public convenience.
Safeguards:
- Provides for publication of draft proposals, public objections, and hearings before finalisation.
- Once notified, Commission orders become legally binding and generally cannot be challenged in courts.
Executing Women’s Reservation:
- The Commission will determine seat allocation, redraw constituencies, and identify seats reserved for SCs, STs, and women.
