it has certain functions conferred upon it for enforcing an award
already made. But for making an award its power of moving is entirely conditional upon the existence of a dispute. It may, of course, for the purpose of the day, conclude there is a dispute and proceed, but that is subject to legal examination in the ordinary way.
The applicants come forward to this Court and say that the condition does not exist. They say that it does not exist because the dispute which formerly existed has ended. I do not call the
AUSTRALIAN wav it ended a res judicata at all, because no Court of Justice has
ever dealt with it. The question is whether it still exists or has ceased to exist. If Mr. Starke had convinced me that there was no dispute in existence at the present time, I should have felt myself bound, in accordance with the law laid down in Mayor &. of London V. Cox 1, to assent to his application for a prohibition. In addition to the passages I have read from the judgment of Willes J., I will read another 2 :- As to the practice since the Statute 1 Will. IV. c. 21, it has been uniform to the effect that prohibition may go in the first instance without the question of jurisdiction being raised by any pro- ceeding in the Court below, or even after a plea therein giving the go-by to that question. It was SO decided by Justice Wightman, in the case of a prohibition to the County Court: Sewell v. Jones 3, and such has been the constant practice in like cases." Therefore
I should have felt bound to issue a prohibition. But the ground upon which I agree to the refusal is that laid down by Jervis C.J. in In re Birch 4: "A prohibition is not a matter of absolute right: the party asking for it is bound to make out a clear case." By a matter of absolute right " he means a matter of course." Cresswell J. said 5: "We are not bound to grant a prohibition
unless we are clearly satisfied that the inferior jurisdiction is about to exceed its powers." That, I understand, is clear, and in Farquharson v. Morgan 6 Lord Halsbury, Lopes L.J. and Davey L.J. laid it down most emphatically that prohibition is not a matter of discretion. If want of jurisdiction is shown, then prohibition must go.
