Registration requirements for multi State co operative societies hinge on compliance with statutory criteria and prudential norms. Registration requires the Central Registrar's satisfaction that statutory and rule requirements are met, that the society's objects serve members in more than one State, and that bye laws advance members' social and economic betterment consistent with co operative principles and not contrary to the Act or rules. For societies engaged in thrift and credit, registration also depends on conformity of paid up capital, reserves and prudential parameters with prescribed guidelines, with transitional compliance and supervisory directions applicable; Reserve Bank norms govern multi State co operative banks. Applications must be disposed of within the prescribed period, refusals must state reasons after hearing, and failure to act results in deemed acceptance.
