Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
The anti-defection law was introduced through the Fifty-Second Amendment Act of 1985 to stop opportunistic party-hopping by elected lawmakers. Contained in the Tenth Schedule, the law disqualifies legislators who voluntarily give up party membership or defy party whips. The Ninety-First Amendment of 2003 strengthened these rules by deleting the one-third split defense, requiring at least a two-thirds majority to validate political mergers, and capping ministry sizes at fifteen percent.
In UPSC prelims and SSC exams, questions frequently test disqualification exceptions and judicial rulings. A notorious trap concerns independent and nominated members: independent candidates face disqualification if they join any political party after election, whereas nominated members have a six-month window to join one. Remember the Kihoto Hollohan verdict of 1992, which established that the Speaker's disqualification order is subject to judicial review. Also revise the 2020 Keisham ruling requiring Speakers to decide petitions within three months.
