12.—(1) The Department may by regulations provide—
(a)for officers authorised by the Department to make any determinations which fall to be made by an appeal tribunal and which do not involve the determination of any appeal, application for leave to appeal or reference;
(b)for the procedure to be followed by such officers in making such determinations;
(c)for the manner in which such determinations by such officers may be called in question.
(2) A determination which would have the effect of preventing an appeal, application for leave to appeal or reference being determined by an appeal tribunal is not a determination of the appeal, application or reference for the purposes of sub-paragraph (1).
