Trinamool rebellion revives govt. hopes on Delimitation Bill
The Delimitation Bill touches on constitutional amendment procedures (special majority requirements), the federal balance between states with differing population growth rates, and the political dynamics of coalition/opposition management in Parliament. The bill's fate and the special majority requirement are textbook GS II topics. The TMC rebellion angle also illustrates how anti-defection law and parliamentary arithmetic interact.

Concepts to know
Delimitation is the act of redrawing the boundaries of parliamentary and assembly constituencies, usually after a census. It is carried out by a Delimitation Commission under the Delimitation Act to ensure population-proportional representation.
Article 368 governs the procedure to amend the Constitution. Certain amendments require a special majority — i.e., a two-thirds majority of members present and voting AND a majority of the total membership of each House.
A constitutional amendment bill that proposes to redraw electoral boundaries based on the 2011 Census; requires passage by a special majority in both Houses of Parliament.
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.
For constitutional amendments under Article 368, a bill must be passed by a two-thirds majority of members present and voting, which must also constitute a majority of the total membership of that House. It is stricter than a simple majority.
Enshrined in the Tenth Schedule of the Constitution, it disqualifies MPs/MLAs who voluntarily give up party membership or vote against party whip; relevant here because rebel TMC members voting for the bill could face disqualification.
