Muslim law

I am pursuing law and have a moot court session on the case.. the brief of case is that both husband and wife are got married in 2006 and both are qualified and both are working. in 2009 wife wants a child and stay at home on which husband does not agree he says its too early. they have a heated arguments on this matter.in 2010 they again have a heated argument and husband goes down for a walk and returns after 2 hours and says talaq 3 times. 1 of her cousin is the witness to the talaq. wife files an appication under protection of women act before the magistrate for not seeking to dispossessing her from the apartment which is the rented apartment. she also approched to civil court seeking that declaration of talaq is invalid under islamic law. sohail argued that it gives gives women beyond the period of iddat is against his fundamental right to practce religion. wife application under domestic violence is allowed while the civil suit declaration has been dismissed. thus writ petition has been filed by both wife and husband befoer navi delhi high court which have been connected by the court order and are listed together for final disposal. in this case i am a respondent. so my questions for this case are 1.the case will be as sohail v state of navi dally? what points are there where i can debate on? the case fild by wife is valid under DV act and civil court for dispossessing her and validity of talaq? if the talaq is invalid then is it that the husband and wife have to continue the marriage? is the civil court competent to hv jurisdiction for such case. or she must have filed her case in family court?
