"... the question of leave to appeal has been entrusted, by s 38(4)(b) and (5) of the Commercial Arbitration Act, when read together with the provisions of the Supreme Court Act, to a single judge of the Supreme Court.
While it is true, as I have said, that the framers of the legislation could, very easily, have included a provision as to finality of the decision of the single judge to whom the application is made but did not do so, it seems to me that the better view is that, notwithstanding that omission, it sufficiently appears from the material provisions of s 38 of the Act, read in the context of the Act as a whole (and having regard for the emphasis of the Act to which I have earlier referred and the intention which, self-evidently, underpins the requirement to obtain leave), that the discretion so entrusted was not intended to be one from which there is any appeal. That is, I think, the 'natural understanding' of the legislation: see Electric Light and Power Corporation (at 560).
In D'Esterre v Austplat Minerals NL (In Liq) (1991) 4 WAR 549 (in which the Full Court of this Court expressed a preference for a construction of s 60(1)(f) of the Supreme Court Act which would lead to the consequence that there can be no appeal from the refusal of a Judge or Master to grant leave to appeal from an interlocutory order or judgment given by that judge or Master) Malcolm CJ, with whom Rowland and Walsh JJ were in agreement, referred with approval to the joint judgment of Fox and Forster JJ in Reid v Nairn (1985) 60 ALR 419 at 421, in which their Honours said (in the context of interlocutory matters) that 'an appeal from the grant or refusal of leave (before the substantive matter is dealt with) is a thoroughly undesirable addition to legal remedies'.
For myself I would have thought that an appeal from the grant or refusal of leave to appeal from the decision of an arbitrator, whether the substantive matter has or has not been dealt with, is likewise a thoroughly undesirable (and unintended) addition to legal remedies in the context of an Act which, as I have said, is designed to provide speedy, informal and comparatively inexpensive relief to litigants and which, as I have also said, is designed to minimise interference by the Supreme Court.
I should perhaps add that it does not seem to me to be open to the appellant to renew its application for leave to appeal from the award in the manner in which the Full Court of this Court has said, in SCM Chemicals Ltd v Saipem Australia Pty Ltd (1991) 4 WAR 569, might be done in the case of a refusal, by a Master, for leave to appeal against an interlocutory order made by that Master.
Once it is accepted, as I do accept, that the intention underlying s 38(4) of the Act is that the decision of a single judge of the Supreme Court on an application under that section should be final then it seems to me to matter little whether the contemplated further approach to the Supreme Court is one by way of a right of appeal or one by way of the renewal of an application for leave to appeal. Either approach (and that of renewal has not been pursued in these proceedings) is in my view intended to be excluded, regardless of whether the order refusing leave to appeal is regarded as interlocutory or final.
In any event, so far as this last point is concerned, the decision in SCM Chemicals dealt only with the renewal of an application for leave to appeal which had been made ex parte under the provisions of s 60(3) of the Supreme Court Act. The court there referred to and relied in part upon the provisions of O 63, rr 7(2) and 8 of the Rules of the Supreme Court which address only the situation in which an ex parte application has been refused by a judge or Master. Those rules have no application to the situation which prevails in this case in which, by virtue of the provisions of O 81D, r 10, a motion for leave is required, in effect, to be brought inter partes, involving the issue and service of a summons for directions addressing inter alia, such matters as the filing and serving of written submissions."
