The argument as to the jurisdiction of the Commission proceeded in the absence of evidence other than, it would appear, a statement of agreed facts. That statement evidenced, in each case, essentially that the relevant franchise agreement had been entered into and the performance of it had been guaranteed by certain of the applicants as there provided. A copy of the relevant franchise agreement was accordingly before the Commission. It appears that no other evidence of substance was then given and in particular no evidence as to the circumstances of the franchise agreement or of any arrangement, condition or collateral arrangement relating to it. Were the matter to proceed before the Commission it would no doubt be open to the parties to produce evidence in relation to such matters. However, the argument before the Commission and before this Court has proceeded by reference only to the brief statement of agreed facts and the terms of the relevant franchise agreement.

These matters are relevant in an application for relief such as is now sought from this Court. In so far as prerogative relief is sought on the ground that the arrangement which has been made does not fall within s.88F, it is in principle necessary that this Court know what the arrangement in question is so that it can determine whether that arrangement is one which falls within s.88F. Ordinarily, what the arrangement is can be determined only after the whole of the evidence has been given before the Commission and the Commission has made the findings of fact necessary to determine what the arrangement is. However, it is often sensible for the parties to attempt to avoid the time and expense involved in a full hearing of the proceeding and for this purpose the course is sometimes adopted of inviting this Court to act upon an agreed basis. But, at least in a case such as the present, the Court may do so only where the agreement demonstrates what, after a full determination by the Commission, the arrangement is or, at least, the agreement lays down the parameters within which a finding as to the arrangement can be made.
We would draw from those authorities the proposition that whilst it is desirable for a case to be determined at an early stage it is only open to do so at the appropriate stage of the proceedings, that is, where the facts, either established by evidence or plainly agreed in terms, enable the Court to determine what the contract or arrangement is or, at least, the parameters of the contract or arrangement. In other words, it seems to us, unless the facts are sufficiently established to enable the Court to be satisfied it has the necessary material to reach a clear and final decision on the question then the appropriate stage has not been reached for such a determination to be made. In General Steel Industries Inc. v. Commissioner for Railways (N.S.W.) (1964) 112 CLR 125 Barwick C.J. held that the jurisdiction to terminate an action summarily for want of a cause of action in the plaintiff was to be sparingly employed and ought not to be used save where the lack of the cause of action was clearly demonstrated. The Chief Justice commented (at 128,129):
