Subject to any requirement of rules of procedure as to leave to appeal, any party to an appeal to an adjudicator may, if dissatisfied with his determination thereon, appeal to the Appeal Tribunal, and the Tribunal may affirm the determination or make any other determination which could have been made by the adjudicator.
Directions given by an adjudicator under section 19(3) above need not be complied with so long as an appeal can be brought against his determination and, if such an appeal is duly brought, so long as the appeal is pending; and if the Tribunal affirm his determination allowing the appeal, they may alter or add to his directions and recommendations under section 19(3) or replace them with their own directions and recommendations, and the provisions of that subsection shall apply to directions given by them accordingly.
Where an appeal is dismissed by an adjudicator but allowed by the Tribunal, section 19(3) above shall apply with the substitution of references to the Tribunal for references to the adjudicator.
