122. The Tribunal may hear the application and render a decision or issue an order despite the absence of a party or his attorney who, although duly notified of the hearing, fails to present himself on the day of the hearing at the appointed time and place, refuses to be heard or fails to present his views in writing as required.
The Tribunal is required to postpone the hearing, however, if the absent party or attorney has given the Tribunal a valid excuse for his absence.
