Why in news?

The government has proposed increasing Lok Sabha seats from 543 to 816 — a 50% rise — based on the 2011 Census (rather than the upcoming Census) to implement the Nari Shakti Vandan Adhiniyam (Women's Reservation Act), 2023.

The proposal, being discussed with various political parties to build consensus, is likely to face significant legal and constitutional hurdles.

What Is Being Proposed?

• Lok Sabha seats to be increased from 543 to 816.
• 273 seats to be reserved for women (33% of 816).
• Delimitation to be based on the 2011 Census, not the upcoming Census.
• Existing proportional representation among states to be maintained.
• A similar increase proposed for state Assembly seats.

Why the 2011 Census?

• The Women's Reservation Act, 2023 links the implementation of the quota to delimitation, which in turn requires a fresh Census.
• By using the 2011 Census instead of waiting for a new one, the government aims to fast-track implementation while avoiding the politically sensitive issue of states with higher populations — largely in the north — gaining seats at the expense of southern states that have performed better on population control.

Constitutional Provisions Governing Lok Sabha Seat Allocation

• Article 81 establishes the foundational principle of equal representation in the Lok Sabha through two key clauses:
  • Article 81(2)(a) — The ratio between the number of seats allotted to a state and its population must be, as far as practicable, the same for all states.
  • Article 81(2)(b) — Each state must be divided into constituencies such that the ratio between the population of each constituency and the number of seats allotted to it is, as far as practicable, uniform throughout the state.
• Article 81 makes a single exception — very small states with a population not exceeding 6 million are allowed disproportionate representation to ensure they still receive adequate representation in the Lower House.
• Article 82 mandates that upon the completion of each Census, both:
  • The allocation of Lok Sabha seats to states, and
  • The division of each state into territorial constituencies

The Delimitation Freeze: Why Lok Sabha Seats Have Been Unchanged Since 1971

• The current freeze on delimitation — meaning Lok Sabha seat allocation has remained unchanged since 1971 — is the result of two successive constitutional amendments:
  • 1976 Amendment — Froze the definition of "last preceding census" in Articles 81 and 82 to mean the 1971 Census for the purpose of seat allocation among states. This freeze was set for 25 years.
  • 2001 Amendment — Extended the freeze further, until the "relevant figures for the first census taken after the year 2026 have been published". The freeze will thus automatically expire once the current Census figures are released.
• Why Was the Freeze Introduced?
  • The core reason was the fear of southern states losing political representation:
    • Southern states had stabilised their populations through effective family planning.
    • Several northern states, however, were experiencing rapid population growth.
    • Under a strictly population-based delimitation, southern states would have seen their relative share of Lok Sabha seats decline — effectively penalising them for their success in controlling population growth
  • The freeze was thus a political compromise to ensure that states were not disadvantaged for performing better on demographic indicators.

The Road Ahead: How Delimitation Will Proceed?

• If the government chooses not to extend the freeze, the next step would be Parliament passing a new Delimitation Act under Article 82.
• This is the established constitutional process:
  • Census conducted → figures published
  • Parliament passes a Delimitation Act
  • Central Government constitutes a Delimitation Commission
  • The Commission demarcates boundaries of Parliamentary constituencies as per the Act
• The Last Delimitation Exercise
  • As per the Election Commission, the most recent delimitation of constituencies was conducted on the basis of 2001 Census figures under the Delimitation Act, 2002.
  • This was an intra-state delimitation — redrawing constituency boundaries within states — and is distinct from the inter-state seat allocation, which has remained frozen since 1976.

Legal Tests: The Constitutional Hurdles Ahead

• The Core Constraint: Article 81
  • Any delimitation exercise using the 2011 Census must comply with Article 81's "one person, one vote, one value" principle — ensuring each constituency has roughly equal population.
  • Unless Article 81 itself is amended, the Delimitation Commission cannot arbitrarily increase seats by 50% per state without being bound by this principle.
• Two Possible Legal Routes
  • Route 1: Amend the Nari Shakti Vandan Adhiniyam
    • If women's reservation is delinked from the next Census and delimitation by amending the Act itself, there would be no need for a Delimitation Commission — and reservation would automatically come into force.
    • This is the simpler path.
  • Route 2: Amend Articles 81 and 82
    • If the government proceeds with delimitation using 2011 data, it would need to amend Articles 81 and 82 — opening the door to judicial challenge on multiple grounds.
• Constitutional Challenges
• Violation of Right to Equality — Amending Article 81(2)(a) to do away with the "one person, one vote" principle could be challenged as violating Article 14 (Right to Equality) and thereby the Basic Structure of the Constitution.
• Article 14's Reasonable Classification Test — Even invoking positive discrimination under Article 14 would require proving that southern states need special protection based on backwardness — a standard India's legal system currently does not recognise for states with better development indicators.
• Delimitation Commission's Judicial Reviewability — Any constitutional violations by the Commission can be challenged in court.
• A Possible Way Out: The "Compensatory Principle"
  • Experts suggests that since constitutional amendments are inevitable, Parliament could devise a "compensatory principle" to address the concerns of southern states — potentially offering them safeguards against losing relative representation.
