The Registrar is responsible for registering trade unions under the Trade Unions Act, 1926. The Registrar will register a trade union if it complies with the requirements regarding membership, rules, and other particulars outlined in the Act. The Registrar can cancel a trade union's registration if it was obtained by fraud, the trade union ceases to exist, or violates provisions of the Act. An aggrieved person can appeal the Registrar's decision to refuse or cancel registration to the appropriate appellate court.
