What is Delimitation?

Delimitation is the process of fixing or redrawing boundaries of territorial constituencies for the Lok Sabha and State Legislative Assemblies to ensure each seat represents roughly equal number of voters.

Constitutional Mandate

  • Article 82: Mandates Parliament to enact a Delimitation Act after each census, readjusting Lok Sabha seat allocation to states and dividing states into territorial constituencies
  • Article 170: Provides for similar readjustment of seats and constituencies in State Legislative Assemblies
  • Article 81: Dictates the principle of equal representation; the ratio between a state's allocated seats and its population must be roughly the same across all states

Delimitation Commission

  • Composition: 3 members - a Chairperson (serving or retired Supreme Court Judge), Chief Election Commissioner (or an Election Commissioner nominated by them), and State Election Commissioners of concerned states
  • Powers: Orders have the force of law and cannot be challenged in any court
  • History: Set up four times - 1952, 1963, 1973, and 2002

Key Provisions of Three Bills

  • Removes Delimitation Freeze: Amends Article 82 to allow delimitation using data from 2011 Census instead of waiting for post-2026 Census
  • Expedites Women's Quota: Amends Article 334A to implement 33% women's reservation targeting 2029 elections
  • Requirement: Special majority in Parliament and ratification by at least half of the States

2. The Delimitation Bill, 2026

3. Union Territories Laws (Amendment) Bill, 2026

  • Extends structural changes to Union Territories with own legislatures

  • Ordinary bill requiring simple majority

Women's Reservation: Nari Shakti Vandan Adhiniyam

  • 106th Constitutional Amendment Act, 2023 mandates 33% reservation for women in Lok Sabha and State Legislative Assemblies
  • Mandatory sub-quota for women within seats reserved for SCs and STs
  • Rotation: Reserved constituencies will be rotated after each delimitation cycle
  • Sunset Clause: Valid for initial period of 15 years; Parliament can extend through legislation

Freeze on Delimitation: Historical Context

  • 42nd Amendment Act, 1976: Froze total Lok Sabha seats on 1971 Census
  • 84th Amendment Act, 2001: Extended freeze until first census after 2026
  • Rationale: Ensure states implementing population control measures (primarily Southern states) were not penalized with reduced political representation
  • 2002 Commission redrew internal boundaries within states (2001 Census), but inter-state allocation remains based on 1971 data

Arguments Regarding Proposed Delimitation

Arguments Against

  • Penalising Demographic Success: Southern states being punished for successful family planning policies
  • Loss of Political Representation:
  • Uttar Pradesh: 14.73% → 16%+
  • Kerala: 3.68% → 2.7%
  • Tamil Nadu: 7.18% → 5.88%
  • Impact on Presidential Electoral College: Changes fundamental arithmetic of Electoral College
  • Assault on Federalism: "Backdoor" method to centralize political power
  • Gerrymandering Concerns: Possibility of manipulating electoral boundaries for unfair advantage
  • Economic Disparity: "Taxation without adequate representation" scenario

Arguments For

  • Democratic Principle: "One Person, One Vote, One Value" - currently an MP in UP represents millions more citizens than an MP in Kerala
  • Absolute Seat Increase: No state will lose current absolute number of seats; all states see ~50% increase
  • Facilitating Women's Representation: Allows 33% quota without shrinking general seats pool

Judicial Review

In Kishorchandra Chhanganlal Rathod Case, 2024, Supreme Court held that an order by Delimitation Commission can be reviewed if it is clearly arbitrary and violates constitutional values.

Way Forward

  • Consensus Building: Through Inter-State Council and consultations with State governments
  • Hybrid Model: Give weightage to demographic performance, economic contribution (GSDP), and geographic size
  • Strengthening Rajya Sabha: Equal representation to all states (like US Senate) to safeguard federal voice
  • Decoupling Quotas: Implement 33% Women's Reservation within existing strength
