2.—(1) If it appears to the Chief Child Support Commissioner (or, in the case of his inability to act, to such other of the Child Support Commissioners as he may have nominated to act for the purpose) that an appeal falling to be heard by one of the Child Support Commissioners involves a question of law of special difficulty, he may direct that the appeal be dealt with, not by that Commissioner alone, but by a tribunal consisting of any 2 or 3 of the Child Support Commissioners.
(2) If the decision of such a tribunal is not unanimous, the decision of the majority or, in the case of a tribunal consisting of 2 Commissioners, the decision of the presiding member shall be the decision of the tribunal.
