Corruption

Invalid sanction under Prevention of Corruption Act

I am an accused of the offence committed under section 13(1)- (c)(d)(e) of the prevention of corruption act. When the case was filed, the FIR was not coupled with a valid sanction of the competent authority. Therefore, I opposed the cognisance taken by the special court constituted under the prevention of corruption act. Later on, prosecution approached the state government for granting a valid sanction.

Consequently, the competent authority of the state government granted a valid sanction and prosecution submitted it before the court. Now I want to challenge this second sanction issued against me. What is the possibility?
