The law is well settled that the prerogative writ of certiorari is available under the Constitution of the Federal Republic of Nigeria, 1999 in section 272(2) and the various State High Court laws and the State High Court (Civil Procedure) Rules to empower the various High Courts to act as watch dogs over judicial activities of inferior courts or tribunals. The process is meant to provide a supervisory process to keep in check the excesses and arbitrariness of such courts. Denning L. J. (as he then was) precisely put it in Rex v. Northumberland Compensation Appeal Tribunal Ex-parte Shaw (1952) 1 KB 338 at 346-347 thus: “The court of king’s bench has inherent jurisdiction to control all inferior tribunals, not in an appellate capacity, but in a supervisory capacity…This control extends not only to seeing that inferior tribunals keep within jurisdiction, but alsoto seeing that they observe the law. The control is exercised by means of a power to quash any determination…which on the face of it offends against the law.”
