i want to file PIL against personal law

i want to file PIL againest government, my argument point is in india every Citizen have only Citizenship and this one is only Indian citizenship. there are not different Citizenship for Hindu or muslim or there are no different citizenship with respect to state. if one Citizenship then why there are parallel more then one personal law for Indian law, old goverment is made this law for vote bank raajneeti. if there are gap in indian law then goverment should take care to make law properly. my suggestion is One Citizenship one law. if personal law will remain continue then this thing will prove that our indian law is weak and useless for indian public so and there are gap or no provision for citizen's issue.
