9.—(1) The tribunal shall, so far as it appears to it appropriate, seek to avoid formality in its proceedings and shall not be bound by any statutory provision or rule of law relating to the admissibility of evidence in proceedings before the courts of law. The tribunal shall make such enquiries of persons appearing before it and witnesses as it considers appropriate and shall otherwise conduct the hearing in such manner as it considers most appropriate for the clarification of the issues before it and generally to the just handling of the proceedings.
(2) Subject to paragraph (1), at the hearing of the originating application a party shall be entitled to make an opening statement, to give evidence, to call witnesses, to cross-examine any witnesses called by the other party and to address the tribunal.
(3) If a party fails to attend or to be represented at the time and place fixed for the hearing, the tribunal may, if that party is an applicant, dismiss or, in any case, dispose of the application in the absence of that party or may adjourn the hearing to a later date; provided that before dismissing or disposing of any application in the absence of a party the tribunal shall consider his originating application or notice of appearance, any representations in writing presented by him in pursuance of rule 8(4) or (5) and any written answer furnished to the tribunal pursuant to rule 4(3).
(4) A tribunal may require any witness to give evidence on oath or affirmation and for that purpose there may be administered an oath or affirmation in due form.
