At any stage of the proceedings on an appeal under Article 180 or 184(1), the Authority may, and if so directed by the High Court shall, state in the form of a special case for the decision of the High Court any question of law arising in those proceedings.

The decision of the High Court on a special case under this Article shall be deemed to be a judgment of the Court within the meaning of section 35 of the Judicature (Northern Ireland) Act 1978 (c. 23) (which relates to the jurisdiction of the Court of Appeal); but no appeal to the Court of Appeal shall be brought by virtue of this paragraph except with the leave of the High Court or of the Court of Appeal.
