Sanction is a condition precedent to the institution of the prosecution. of a public servant. As per provisions of Section-19 of the PC Act, 1988, no. court shall take cognizance of an offence punishable under sections 7, 10, 11, 13 and 15 alleged to have been committed by a public servant, except with.the previous sanction of the competent authority. Similar provisions are available under section 197 Cr.P.C for offences under IPC.

You may file a quash petition before high court under section 482 cr.p.c. to quads the charge sheet on the said grounds besides some merits in your side to defend your interests.
