(1)  In any proceeding, the Court or a judge, on application, may direct that a question of law be raised for the opinion of the Court.

(2)  The question may be raised either by special case or otherwise if it may be convenient to decide the question –

(a) before any evidence is given or any question or issue of fact is tried; or

(b) before any reference is made to a referee or arbitrator.

(3)  Any further proceeding that the decision of a question under subrule (1) renders unnecessary may be stayed.
