Anti-Defection Law

The Anti-Defection Law was introduced by the 52nd Constitutional Amendment, 1985, which added the Tenth Schedule to the Constitution. Its purpose was to curb the evil of political defections — the practice of legislators switching parties for personal gain, often to topple or prop up governments, memorably called 'Aaya Ram, Gaya Ram' politics. The law aims to bring stability to governments and ensure that legislators remain loyal to the party on whose ticket they were elected.

Background and purpose

Before 1985, rampant defections — where legislators changed sides for office or money — made governments unstable and undermined the mandate of voters. To end this, the 52nd Amendment inserted the Tenth Schedule, providing for the disqualification of members who defect. It was a landmark reform in strengthening the party system and the stability of elected governments in India.

Grounds for disqualification

A member of Parliament or a state legislature can be disqualified on two main grounds: if they voluntarily give up the membership of their political party, or if they vote or abstain in the House contrary to the direction (whip) issued by their party, without prior permission, and the party does not condone it within fifteen days. 'Voluntarily giving up membership' has been interpreted broadly by courts to include conduct that clearly shows a member has left the party, even without a formal resignation.

Independent and nominated members

The law also covers independent and nominated members. An independent member (elected without a party affiliation) is disqualified if they join any political party after the election. A nominated member is disqualified if they join a political party after the expiry of six months from taking their seat — the six-month window gives them a one-time choice to join a party.

Exceptions — merger

There is an important exception: disqualification does not apply in the case of a merger, where at least two-thirds of the members of a legislative party agree to merge with another party. Notably, the original Tenth Schedule also exempted a 'split' by one-third of members, but this loophole was widely misused to engineer defections, and was deleted by the 91st Constitutional Amendment, 2003. Now only mergers (two-thirds) are protected.

Role of the presiding officer

Questions of disqualification are decided by the presiding officer of the House — the Speaker of the Lok Sabha/Assembly or the Chairman of the Rajya Sabha/Council. Initially, this decision was considered final, but in the Kihoto Hollohan case (1992), the Supreme Court held that it is subject to judicial review. The Court has since criticised long delays by Speakers in deciding defection cases and even suggested that an independent tribunal might be better suited to these decisions.

Criticisms and reforms

While the law has curbed casual defections, critics argue it undermines the freedom of legislators to dissent, strengthening party high commands and weakening genuine debate — since members must always follow the whip. The wide power of the Speaker, who is often from the ruling party, and delays in deciding cases have drawn criticism. Reform suggestions include limiting the whip to crucial votes (like no-confidence and money bills), fixing time limits for decisions, and transferring the deciding power to the President/Governor acting on the Election Commission's advice, or to an independent body.

Why it matters for UPSC

The Tenth Schedule — its amendment number (52nd), the two grounds for disqualification, the treatment of independent and nominated members, the merger exception, the deletion of the split provision by the 91st Amendment, and the Speaker's deciding role — is regularly tested, especially in current-affairs-linked questions about defections and Speaker's rulings.
