McDonald v Supreme Court of South Australia

The applicant, Mr McDonald, sought judicial review of two decisions made by the Supreme Court of South Australia. The first decision was by a Master of the Court to reject documents for filing as an abuse of process, and the second was a refusal to remit or reduce the filing fee. The Supreme Court heard the application for judicial review of these decisions. The primary legal issue in this case was whether the supervisory jurisdiction of the Supreme Court extends to the review of decisions made by its members. The court had to determine whether it had the inherent supervisory jurisdiction to review its own decisions, particularly those made by its Masters.

The Supreme Court examined the historical origins of its supervisory jurisdiction, inherited from the English courts, to ascertain the nature and scope of its jurisdiction. It found that the Court of King’s Bench historically had a general supervisory jurisdiction over all English courts and tribunals. The court concluded that the supervisory jurisdiction of the Supreme Court was limited and did not extend to reviewing its own decisions. The court emphasised that the supervisory jurisdiction was intended to ensure that inferior courts and tribunals did not exceed their jurisdiction, and did not apply to the Court itself.

The court determined that it lacked jurisdiction to consider the validity of its own decisions. It noted that Mr McDonald had already achieved the outcome he sought by having the filing fee waived. Consequently, the application for judicial review was rendered redundant. The court found that the supervisory jurisdiction of the Supreme Court did not encompass the review of its own decisions, thereby upholding the decisions made by the Master.

The Supreme Court dismissed the application for judicial review. The court held that it did not have the inherent supervisory jurisdiction to review decisions made by its members, particularly in relation to the rejection of documents for filing and the refusal to remit or reduce the filing fee. The court's supervisory jurisdiction was confined to ensuring that inferior courts and tribunals adhered to their jurisdictional limits.
