In a setback for Congress leader P Chidambaram, the Supreme Court on Monday refused to entertain his petition challenging the dismissal of anticipatory bail in a corruption case lodged by the CBI in the INX media scam. At the outset, a bench comprising justices R Banumathi and AS Bopanna said since Chidambaram has already been arrested and is in the custody of the CBI, his appeal in the case has become infructuous. However, the bench said Chidambaram is at a liberty to seek remedy in accordance with the law.
