The 52nd Amendment Act, 1985, introduced the Tenth Schedule to the Constitution, popularly known as the Anti-defection Law. This law lays down the provisions for disqualification of Members of Parliament and State Legislatures on the grounds of defection. The power to decide on the disqualification of a member under this law rests with the Speaker of the Lok Sabha or the Chairman of the Rajya Sabha (or the Speaker/Chairman of the State Legislature). This vested significant power in the hands of the presiding officers concerning the membership status of elected representatives, thus strengthening their position.
