The Supreme Court on Wednesday heard the plea filed by Telangana CM Revanth Reddy in 2015 'cash for vote' case. Senior Advocate Mukul Rohatgi, appearing for Revanth Reddy, told the Court that the trap laid by Anti-Corruption Bureau (ACB) in the 2015 cash-for-vote case was 'completely illegal' as it was conducted before the registration of any FIR.
