It is well established that the legitimate role of the Court in applications for leave to appeal under s.38(5) of the Act is very circumscribed. The legislation restricts the court's jurisdiction to review arbitral awards in recognition of the importance of speedy finality in that context. Nevertheless, the power to review is enlivened by an obvious departure from settled principles of law. The basic principles relevant to the determination of an application for leave to appeal pursuant to s.38(5) of the Act were conveniently summarised by Debelle J in Leighton Contractors Pty Ltd v South Australian Superannuation Fund Investment Trust as follows -
(1) there is no appeal from an arbitrator on a question of fact;
(2) while s.38 provides that an appeal shall be from the award of an arbitrator on a question of law, leave must nevertheless be obtained unless both parties consent to the appeal;
(3) leave will only be granted in circumstances prescribed in s.38(5);
(4) the applicant for leave must satisfy both para(a) and para(b) of 38(5);
(5) the epithet `manifest' in the expression `manifest error of law' is used to indicate an error which is evident or obvious rather than one which is arguable;
(6) if the court determines that there is no manifest error of law, an application based on this ground fails;
(7) if the court is satisfied that a manifest error of law exists, a question arises whether the court should, in the exercise of its discretion, grant leave; and
(8) assuming that there is not a manifest error of law on the face of the award, it may be argued that there is strong evidence that the arbitrator made an error of law and the determination of the question may add, or may be likely to add, substantially to the certainty of commercial law. This requirement indicates that the question should be one of wider and greater importance than, for example, the construction of a one-off clause in the context of the particular agreement between the parties.[2]
