Constitution Amendment Bill moots possible change in size of State Assemblies

Why it matters for UPSC

The Constitution (106th Amendment) Act 2023 introduced women's reservation but made it contingent on a fresh delimitation post-Census. This item highlights the operative provision (Article 334A) and its practical trigger conditions, which are core to understanding constitutional amendments, delimitation process, and representation of women in legislatures — all key GS II themes.

Key facts

  • The Bill substitutes Article 334A to operationalise one-third reservation for women in State Assemblies and Lok Sabha.
  • Reservation will come into effect only after a fresh delimitation based on the latest published Census.
  • The latest published Census as of now is the 2011 Census; the 2021 Census has not yet been conducted/published.
  • Women's Reservation was enacted via the Constitution (106th Amendment) Act, 2023.
  • Delimitation is the process of redrawing constituency boundaries, carried out by the Delimitation Commission under the Delimitation Act.
  • The amendment potentially affects the size/composition of State Assemblies as fresh delimitation may alter seat counts.

The Bill substitutes Article 334A to operationalise the one-third reservation for women in the Assemblies. The provision states that the reservation will come into effect only after a fresh delimitation exercise is carried out on the basis of the latest published Census. As of now, the latest published Census is 2011.

Concepts to know

Article 334Aarticle

Inserted by the Constitution (106th Amendment) Act 2023, Article 334A reserves one-third of seats for women in the Lok Sabha and State Legislative Assemblies. Crucially, the reservation is activated only after a delimitation exercise conducted on the basis of the first Census published after the commencement of this amendment.

Constitution (106th Amendment) Act, 2023act

Also called Nari Shakti Vandan Adhiniyam, this amendment inserts Articles 330A and 332A to reserve one-third of Lok Sabha and Vidhan Sabha seats for women. Implementation is deferred until after the next Census and delimitation.

Delimitation Commissioninstitution

A statutory body constituted under the Delimitation Act to determine the number and boundaries of constituencies for elections to the Lok Sabha and State Assemblies; its orders have the force of law and cannot be questioned in any court.

Delimitation Actact

The Delimitation Act (most recently 2002) provides the legal framework for constituting a Delimitation Commission and the procedure for readjusting constituency boundaries based on census data.

Censusterm

A decennial exercise conducted under the Census Act, 1948 to enumerate India's population. The Census is constitutionally significant as it forms the basis for delimitation and resource allocation; the 2021 Census has been delayed.

Article 82article

Article 82 mandates readjustment of Lok Sabha seats and constituency boundaries after every census. The current freeze on seat readjustment was extended until the first census after 2026 to avoid penalising states with better population control.
