What is Political Defection?
Historical Background
The problem of political defections became widespread in India during the 1960s and 1970s, leading to unstable governments and political uncertainty. Legislators frequently switched parties for personal gain, undermining the democratic process. To address this issue, the Anti-Defection Law was introduced through the 52nd Amendment Act of 1985.
This amendment added the Tenth Schedule to the Constitution, outlining the grounds for disqualification of legislators who defect. Initially, the law allowed for a split in a political party if at least one-third of its members defected. However, this provision was often misused.
The 91st Amendment Act of 2003 changed the split provision, requiring a merger of at least two-thirds of the members of a political party for defection not to attract disqualification. This amendment aimed to strengthen the anti-defection law and further reduce political instability.
