First please be clear under which statute ( i.e. Societies Registration Act, 1860 or the Concerned State Societies Registrations Act, or the Co-Operative Societies Registration Act) the society you are dealing with is registered.
Then go through the Memorandum of Association and/or the bye-laws of the society for the provision to deal with in case of violation of rules by any member of the society.
In the Societies Registration Act, 1860, Refer to Section 6 which provides for suits by and against societies. With respect to who the complant may be made if the bye-laws are silent then Registrar of Societies has powers to enquire into the allegations by or against the society/members.
If even after the intervention of the Registrar, the problem is not solved then you can approach the Civil Court within whose jurisdiction the society is registered.
