Freeze on Delimitation

Freeze on Delimitation

  • Context:

  • The recent defeat of the Constitution (131st Amendment) Bill, 2026 and the consequent lapse of the accompanying Delimitation and Union Territory Bills in the Lok Sabha have temporarily delayed the national controversy surrounding delimitation.

  • These legislative measures were originally introduced to advance the implementation of the women's reservation law by operationalising it within an expanded House

  • The Constitutional Freeze (Article 81):

  • The 2001 Amendment:

  • The Atal Bihari Vajpayee government last froze the delimitation exercise for 25 years in 2001 by amending Article 81 of the Constitution.

  • This amendment extended the freeze on the inter-state distribution of Lok Sabha seats, deliberately keeping them locked to the demographic realities of the 1971 Census.

  • According to the specific provisions of Article 81(3), this freeze remains legally binding until the relevant population figures for the "first census taken after the year 2026 have been published".

  • Crucially, while the total distribution of seats among states relies on the 1971 data, the redrawing of territorial constituencies within a particular state is based on the later 2001 Census.

  • The Impending Expiration and New Census:

  • The Union Cabinet recently announced the next Census exercise, structured in two phases:

  • Houselisting between April and September 2026

  • Population Enumeration in February 2027.

  • Because the final figures are expected to be available in late 2027, this will officially be the first census conducted after 2026.

  • Legal experts clarify that unless explicitly extended, the current freeze will automatically lapse upon the publication of these new figures

  • The Core Conflict:

  • The fundamental constitutional principle enshrined in Article 81 is "one person, one vote, one value".

  • However, populations in states such as UP, Bihar, Rajasthan, Gujarat, and Maharashtra have surged disproportionately since 1971, altering this ratio drastically.

  • Consequently, southern states are expected to heavily pressure the Centre to introduce a new Constitutional Amendment Bill to further extend the freeze and protect their representation, just as was done in 1976 and 2001.
