Dear Sir,
Yes, you can file defamation case because it lowers your image in the family circle which is more important for a person to survive. It is a social stigma falsely created by them. You have to file before magistrate court through advocate u/s 500 Cr.P.C.
They have done a serious mistake by lodging false cases against you thus they have committed a mischief which is unbecoming of holding a public office . you can file a criminal and civil defamation case claiming huge compensation since your reputation in the society has been lowered. The finding given by the court is sufficient to establish defamation. Discharge is a strong document saying that no such complaint ever lodged and no stigma will be attached to you since the said complaint itself erased from the record.
1) Defamation cases are of two types, criminal and civil.
2) In Civil defamation, a mala fide intention to defame is not always necessary. If defamation is caused, thenbsuit lies. Court fees are required to be paid as per value of damages caused to reputation.
3) Criminal defamation must, in addition, contain some deliberate malice or malafide intention, to cause damage to reputation of someone.
Here, court fees are NOT required at The level of a civil case.
At the end of case, court punishes offender if defamation is proved.
3) In civil defamation case, at end of case, court awards damages to compensate loss to reputation if defamation is proved.
