Society registration cancellation power now includes notice, appeal, and finality safeguards under the Delhi amendment. Insertion of section 12D confers power on the Registrar to cancel the registration of a society by written order where the registration, name, or change of name is contrary to the Act or any other law, where the society's activities or proposed activities are subversive of its objects or opposed to public policy, or where registration or renewal was obtained by misrepresentation or fraud. Before cancellation, the society must be given a reasonable opportunity to alter its name or object or to show cause, and an appeal lies to the Commissioner whose decision is final.
