Time limit to file defamation case.

Sir/Madam, I am a government servant and I was targetted by my superior for not supporting his corrupt activities. He got me suspended from service on false charges on 31/03/2022. A departmental inquiry was initiated after a gap of six months, that is on 09/09/2022. A retired judge of repute was appointed by my institution and he conducted the inquiry proceedings for a period of seven months. He concluded/reserved the case for judgement on 15/04/2023. The inquiry report/judgement was submitted by the Inquiry officer after a gap of three months, on 14/07/2023 The report clearly states that the charges made against me are false and also states that I was targetted by my superior. A copy of the Inquiry report was not provided to me till yerterdady, that is, 13/09/2023 and I got the same after much efforts. I want to file a defamation case against my superior seeking punishment and monetory compensation. I humbly request the learned legal experts to please advise, particulary on the time limitations applicable to the above mentioned case. Thanks and Regards
