Five former IDBI Bank executives charge-sheeted by CBI on charges of corruption in the loan default case against Vijay Mallya seek discharge for lack of evidence. CBI opposes pleas, stating the case is still under investigation and awaiting Mallya s extradition. The agency argues there is sufficient evidence to establish criminal conspiracy. The accused maintain their innocence, stating there is no evidence against them and they have not violated any rules. They argue that prosecution without sanction is not permissible in law.
