Anti-Defection Law – Meaning, Provisions, Loopholes & Reforms

The Anti-Defection Law is one of the most significant legal mechanisms to ensure political stability and integrity in Indian legislatures. Introduced to curb the menace of “Aaya Ram, Gaya Ram” politics, the Anti-Defection Law prohibits elected members from switching parties after elections. However, despite its objectives, the Anti-Defection Law has faced criticism for loopholes and political misuse.

The Anti-Defection Law was enacted by the 52nd Constitutional Amendment Act, 1985, which inserted the Tenth Schedule into the Indian Constitution. It lays down the process through which legislators may be disqualified on grounds of defection. The Anti-Defection Law applies to both Parliament and State Legislatures, aiming to bring political discipline and uphold the mandate of the electorate.
