155. Proceedings for review or revocation are brought before the Tribunal by a motion filed at the secretariat of the Tribunal within reasonable time following the decision concerned or following the discovery of a new fact susceptible of warranting a different decision. The motion shall refer to the decision concerned and state the grounds invoked in support of the motion. It shall contain any other information required by the rules of procedure of the Tribunal, and shall indicate, where applicable, the name, address, telephone number and fax number of the representative of the applicant.
The secretary of the Tribunal shall send a copy of the motion to the other parties, who may respond to it in writing within 30 days after receiving it.
The Tribunal shall proceed on the basis of the record; it may, however, if it considers it appropriate or if a party requests it, hear the parties.
