7.—(1) The tribunal may at any time, whether before or after the beginning of the hearing, adjourn the hearing and when so doing may either fix the date, time and places at which the hearing is to be resumed or leave the date, time and place to be determined later by the tribunal but the tribunal shall not be resumed at that date, time or place, unless the tribunal is satisfied that the appellant and the registration authority have been given at least fourteen days notice thereof.
(2) If either the appellant or the registration authority fails to appear or be represented by one of the persons referred to in rule 5 at the time fixed for the hearing of the appeal, the tribunal may take such action whether by proceeding with or adjourning the hearing or otherwise as may appear to the tribunal to be just and expedient.
