The Defection Economy: How Anti-Defection Law Created the Very Instability It Sought to Prevent

The Tenth Schedule of the Indian Constitution, popularly known as the anti-defection law, was added in 1985 to address a specific and well-documented problem: legislators switching parties for personal gain, often immediately after an election, destabilising governments that had just received a popular mandate. The law disqualifies legislators who defect from their party, and on its own terms, it has been reasonably effective at preventing the crude, individual horse-trading the original problem described.

The Workaround

What the law could not anticipate, and has proven structurally unable to prevent, is the engineered mass resignation — a tactic in which a sufficient number of legislators from a ruling coalition resign their seats simultaneously, reducing the government’s majority below the threshold needed to survive a floor test, without any individual legislator technically defecting from their party. Because resignation is a constitutional right rather than a disqualifiable act of defection, this manoeuvre falls entirely outside the anti-defection law’s reach, despite achieving functionally the same outcome the law was designed to prevent: the collapse of an elected government through legislators acting against their party’s collective interest.

The Speaker’s Discretion Problem

A second structural weakness lies in who adjudicates defection disputes: the Speaker of the relevant legislative assembly, an office that is itself a member of, and typically aligned with, one political party. Disqualification petitions against defecting legislators have, in numerous cases, taken months or years to be decided — sometimes resolved only after the legislators in question have already served out a meaningful portion of their term in a new governing coalition, rendering the eventual disqualification ruling largely symbolic. The Supreme Court has criticised this delay and suggested an independent tribunal might be more appropriate, but no such structural reform has yet been enacted.

A law that disqualifies defection but not resignation has not closed the loophole. It has simply told everyone exactly which door to use instead.

The Cost to Governance

Beyond the immediate political drama, the defection economy imposes real governance costs. State governments that know they are perpetually one engineered resignation away from collapse govern with a short time horizon, prioritising visible, short-term measures over the kind of sustained institutional reform that requires years of stable execution. Bureaucracies serving under governments of uncertain tenure have reduced incentive to commit to long-term projects whose political ownership may change abruptly.

Genuine reform would likely require either an independent adjudicating body for defection disputes, replacing the politically conflicted Speaker, or a constitutional mechanism that treats engineered mass resignations functionally similarly to defections when their timing and coordination make the underlying intent unmistakable. Neither reform appears imminent, in part because no party currently holding power has a strong incentive to close a loophole it may itself need to use in opposition.
