Defamation

Dear sir, A former Higher secondary school HM lodged a complaint to the authority without any evidences provided.The petttion was directly filed to my colleque .In the petition some allegations made on me.Following the petition a preliminary enquiry was made by Tashildar even not giving a copy of the petttion or any evidence against the allegations. The enquiry report does not accuse me in a single word where as the enquiry officer clearly reports as two persons I.e the former H.M and my colleque that have committed mistakes.Yet, the Director of the department issued 17(b)Charge Memo with 6 allegations in which4 among them not in the HM 's petttion.Following this, the transfer order issued .The court set aside the the transfer order. Without any single evidence provided by HM. that he had not given in the petttion the authority is doing all evils to me .Still my charge memo pending ,another cherge memo was given with 6 allegations to me for not obeying the transfer order.What type of case can file against the authority ? Can I file criminal defamation suit against the former HM of the school.
