Case filed using false allegations and evidences

He has only approached the Court based on his understanding of the issues.  He has not committed any crime, for which he needs to be punished.  

Perhaps, you have evidence/documents etc., to prove as to what he says/complains about is totally baseless and wrong.  If that be so, then you have to give suitably reply to the complaint / case.   That's all to it. Nothing more.

Yes, if you can further prove that the complainant was fully aware of the existence of all these evidences/documents and yet filed the cases against you then you can seek dismissal of the case and also for imposition of exemplary costs on the complainant. (Court may or may not impose costs.)
