In some states Registrar of Societies is the proper platform to lodge such disputes, court can also be approached. You have not mentioned how you have come to know the irregularities. If you have sufficient proofs you can proceed. Read the Society by-laws and if any thing is against the by-laws approach the Registrar or court.
