"…the application to set aside a default judgment is not the invocation of an appellate jurisdiction but of a specific rule enabling the court to set aside its own orders in certain circumstances where the action has never been heard on the merits. " (Emphasis added.)
"The first point to be considered is whether, assuming that the association was an unlawful one, and that the Court had no jurisdiction to make the order, an appeal is the proper method of getting rid of it. I think it is. I think that an order made by a Court of competent jurisdiction which has authority to decide as to its own competency must be taken to be a decision b y the Court that it has jurisdiction to make the order, and consequently you may appeal from it on the ground that such decision is erroneous."
"In this case an order has been made to wind up an association or company as such. That order was made by a superior Court, which superior Court has jurisdiction in a certain given state of facts to make a winding-up order, and if there has been a mistake made it is a mistake as to the facts of the particular case and not the assumption of a jurisdiction which the Court had not. I am inclined, therefore, to say that this order could never so long as it existed be treated either by the Court that made it or by any other Court as a nullity, and that the only way of getting rid of it was by appeal."
"An order of the Court of Appeal, if not properly constituted, is a nullity. It is, of course, a proper ground of appeal that the court from which the appeal is brought had no jurisdiction to make the order in question; but if that is found to be the case the court hearing the appeal has no jurisdiction to determine the appeal on its merits but is bound to confirm the position by setting aside the order below as a nullity. 35. The parties cannot confer on us by consent a jurisdiction which we do not possess, and since the issue goes to our own jurisdiction then, contrary to the advice given to the parties by the Court of Appeal … we are bound to enquire into it whether the parties raise it or not."
