The Monsoon Session of Parliament opens this morning with the government set to reintroduce a reworked delimitation framework — the same constitutional question that produced April's most dramatic floor defeat, when the Constitution (131st Amendment) Bill fell 54 votes short of the two-thirds majority.

Officials familiar with the revised draft say the new package decouples the most contested element — the use of 2011 census data — from the women's reservation timeline. The reworked bill is expected to anchor delimitation to the 2027 census, whose houselisting phase was notified last week, while proposing an interim mechanism to operationalise the Nari Shakti Vandan Adhiniyam before the 2031 cycle.

The opposition's position has hardened rather than softened since April. Southern-state parties, who led the argument that a 2011-data delimitation would reward northern population growth at their expense, have signalled they will treat any delimitation motion as a confidence question for federalism. The INDIA bloc meets this evening to settle a common floor strategy.

The government's floor arithmetic remains where it was: comfortable for ordinary legislation, short for constitutional amendment. What has changed is the political cost of stalemate. With the women's reservation law now three years old and still unimplemented, both sides enter the session owning a piece of the delay — the government for sequencing reservation behind delimitation, the opposition for voting down the instrument that would have unlocked it.

The session runs 24 sittings to August 21. Beyond delimitation, the legislative queue includes the Overseas Mobility Bill, the National Sports Bill, and the first statutory review of the criminal codes as the Bharatiya Nyaya Sanhita completes two years in force.
