"The jurisdiction of the court to review decisions of inferior courts and tribunals is limited. The jurisdiction is supervisory and does not entitle this court to canvass matters that it would on appeal. In a judicial review the court is exercising common law jurisdiction. The jurisdiction is different from an appeal. The judicial review procedure is concerned with the legality of what was done by the court or tribunal, and is not concerned with the merits of the decision under review. This is to be contrasted from an appeal, where the question usually is whether the decision is right or wrong, whereas the question of a judicial review is whether or not the decision is in accordance with the law. Order 56 is concerned with procedure. It abolishes the remedies and the nature of the old prerogative writs that nevertheless deserve the jurisdiction of the court to make prerogative writ-type orders. It is clear that the rules do not affect the common law jurisdiction of the court, and it is equally clear that this court has jurisdiction to make an order in the form similar to the old prerogative writ of certiorari, namely, quashing the decision under review. The scope of the jurisdiction was recently discussed by the High Court in Craig v South Australia.[3] In a joint judgment the Court said: `Where available, certiorari is a process by which the superior court, in the exercise of original jurisdiction, supervises the acts of an inferior court or tribunal. It is not an appellate procedure enabling either a general review of the order or decision of the inferior court or tribunal, or a substitution of the order or decision which the superior court thinks should have been made. Where the writ runs, it merely enables the quashing of an impugned order or decision upon one or more of a number of distinct established grounds: most importantly, jurisdictional error, failure to observe some applicable requirement of procedural fairness, or fraud, an error of law on the face of the record. Where the writ is sought on the ground of jurisdiction error, breach of procedural fairness or fraud, the superior court entertaining an application for certiorari can, subject to applicable procedural and evidentiary rules, take account of any relevant material placed before it. In contrast, where relief is sought on the ground of error of law on the face of the record, the superior court is restricted to `the record' of the inferior court or tribunal and the writ will enable the quashing of the impugned order or decision only on the ground that it is affected by some error of law which is disclosed by that record'."
