Help Required for a harassment case filed against coperative housin

I was the managing committee member of a coperative housing society form the year 2008-2013.We constructed a society office did some concreting work in the society premises.The person who filed the case went to the civil court instead of the registrar and filed a case.He alleged irregularities in the above work on the basis the audit for that FY was not cleared.The audit was not cleared since he went and raised a question with the auditor.Subsequently we provided clarifications and the audit report was cleared.The case was filed and it was a police case in 2013. The case is still going on and I have moved on to my native place .Every 3 months the case is scheduled and I normally travel to Mumbai.This year I couldn't travel and a warrant was issued.Can this person legally file a case on coperative housing society bypassing the registrar.What should we do with this pending case which is not heard and we are getting dates after dates.
