" ... when I look not only at the language used [in Order LVIII r.15], but at the substance and meaning of the provision, it seems to me that to give an appeal in this case would defeat the whole object and purview of the order or rule itself, because it is obvious that what was there intended by the Legislature was that there should be in some form or other a power to stop an appeal - that there should not be an appeal unless some particular body pointed out by the statute ... should permit that an appeal should be given. Now just let us consider what that means, that an appeal shall not be given unless some particular body consents to its being given. Surely if that is intended as a check to unnecessary or frivolous appeals it becomes absolutely illusory if you can appeal from that decision or leave, or whatever it is to be called itself. How could any Court of Review determine whether leave ought to be given or not without hearing and determining upon the hearing whether it was a fit case for an appeal? And if the intermediate Court could enter and must enter into that question, then the Court which is the ultimate Court of Appeal must do so also. The result of that would be that in construing this order, which as I have said is obviously intended to prevent frivolous and unnecessary appeals, you might in truth have two appeals in every case in which, following the ordinary course of things, there would be only one; because if there is a power to appeal when the order has been refused, it would seem to follow as a necessary consequence that you must have a right to appeal when leave has been granted, the result of which is that the person against whom the leave has been granted might appeal from that, and inasmuch as this is no stay of proceeding the Court of Appeal might be entertaining an appeal upon the very same question when this House was entertaining the question whether the Court of Appeal ought ever to have granted the appeal. My Lords, it seems to me that that would reduce the provision to such an absurdity that even if the language were more clear than is contended on the other side one really ought to give it a reasonable construction. My Lords, I confess that when I look both at the subject matter with which the order deals and at the language of the order itself it seems to me obvious that it was intended that the decision should be final (whether that is said in terms or not seems to me to be immaterial), unless the Court of Appeal, the body there prescribed, in the exercise of that jurisdiction should give leave to appeal."
