The Tenth Schedule was added by the ______ Constitutional Amendment Act, 1985.
Answer: 52nd
The 52nd Constitutional Amendment Act, 1985 added the Tenth Schedule (Anti-Defection Law) to curb political defections motivated by lure of office or similar considerations. It was a response to the 'Aya Ram, Gaya Ram' phenomenon of the 1960s-70s. The law was later strengthened by the 91st Amendment (2003) removing the 'split' exception.
