How 37 Defections Are Doing What Persuasion Could Not

When Defection Does the Work Persuasion Could Not

The text says one thing; the arithmetic is doing another. Article 368 requires a special majority - two-thirds of members present and voting - to amend the Constitution. That threshold exists precisely to force broad consensus on structural changes. What is happening in the run-up to the Monsoon Session tests how much that requirement actually constrains a government once floor-crossing enters the picture.

The Gap That Closed Without a Single Vote Changing In April 2026, the Constitution

(131st Amendment) Bill fell in the Lok Sabha, securing 298 votes against a two-thirds mark of 352 out of 528 MPs present. That defeat reflected the Opposition's actual numerical strength at the time. Since then, according to reporting, 37 Lok Sabha and Rajya Sabha MPs from four anti-BJP parties have defected to the ruling side - the largest floor-crossing to the Treasury benches since the anti-defection law was enacted in 1985.

Twenty of those were Trinamool Congress MPs, six were Shiv Sena (UBT) MPs, in the Lok Sabha alone. None of this reflects a single voter's mind changing or a single argument winning anyone over on the substance of delimitation.

It reflects the Tenth Schedule's own design: a defection survives disqualification proceedings once it clears a two-thirds threshold within the original legislative party, converting individual floor-crossing into legally protected "merger."

What the Tenth Schedule Was Built to Stop and What It Cannot

The anti-defection law was written to prevent exactly the kind of horse-trading that undid governments in the 1960s and 70s - but its merger clause, which shields a defection once it crosses the two-thirds mark within a party's own legislative wing, creates a structural loophole rather than closing one.

A government short of the votes needed to amend the Constitution can, in principle, get there not by building consensus with rival parties but by inducing enough defections within rival parties to trigger the merger exemption.

The Lok Sabha's two-thirds mark itself has shifted with these events - from 352 in April to 360 today, as the House's total strength moved with vacancies and defections. That a constitutionally mandated threshold designed to be hard to move is, in practice, this dynamic is the real story sitting underneath the parliamentary-arithmetic headlines.

For the exam, this is not simply a "delimitation politics" story. It is a live test of how the special-majority requirement under Article 368 interacts with the Tenth Schedule's merger provision - and whether a constitutional safeguard against easy amendment can be worked around through party-level attrition rather than through the cross-party persuasion the special majority was designed to demand.
