Admissibility of consumer complaints: failure to decide is deemed admission and complainant must be given an opportunity to be heard. Proceedings before the District Commission must be conducted by the President with at least one member; if a member cannot continue, the President and remaining member shall continue from the last stage. The Commission may admit or reject a complaint, but rejection requires an opportunity to be heard; if admissibility is not decided within the prescribed timeframe, the complaint is deemed to have been admitted.
