Crime and 4-year punishment

Tamil Nadu Chief Minister (CM) J Jayalalithaa has become the first serving CM to be convicted after the Supreme Court held Section 8 (4) of the Representation of the People Act unconstitutional in July 2013. This took away from MPs, MLAs and MLCs the luxury to have their disqualification held in abeyance for three months, within which time they filed their appeals to higher courts. Congress's Rasheed Masood and Rashtriya Janata Dal chief Lalu Prasad Yadav were the first couple of MPs to be disqualified under the amended rules in September 2013. The court had held legislators cannot contest elections for six years from the date of the end of their prison term. Jayalalithaa is to serve a four-year prison term. So, Jayalalithaa stands immediately disqualified as a legislator and she cannot contest elections for the next 10 years. However, Jayalalithaa can seek re-election if a higher court acquits her as had happened with her in 2001-02.

Abdul Rehman Antulay

Yadav spent time in jail in connection with the case in 1998 and 2001.
