"Where available, certiorari is a process by which a superior court, in the exercise of original jurisdiction, supervises the acts of an inferior court or other 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 the 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, fraud and 'error of law on the face of the record'. Where the writ is sought on the ground of jurisdictional 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."[6]
