(2) That SC person filed again filed his 2nd complaint to Parliament of India against me alleging use of caste based remarks for her. Through Ministry of Home affairs, Delhi Govt. Director of my depart came to my district and an inquiry was conducted against me. In the inquiry report said complaint was found false. Now on the basis of these two complaints can I file a case of criminal complaint for defamation u/s 499/500 IPC against that SC person or the only remedy for me was to file case for damages for malicious prosecution.
