Edwards v Santos Ltd

The High Court of Australia considered an application for writs of certiorari and mandamus concerning decisions of the Federal Court of Australia. The applicants, registered native title claimants, sought to quash orders made by the Federal Court at first instance and on appeal, which had dismissed their proceedings summarily. The dispute arose from negotiations for an Indigenous Land Use Agreement (ILUA) concerning land claimed by the applicants, which was also subject to an Authority to Prospect (ATP) granted by the State of Queensland to Santos Ltd and Delhi Petroleum Pty Ltd. The applicants sought declarations that the grant of a petroleum lease under the ATP would not be valid and would not constitute a "pre-existing right-based act" under the Native Title Act 1993 (Cth).

The central legal issues before the High Court were whether the Federal Court had jurisdiction to hear the matter, whether the applicants had sufficient interest to seek declaratory and injunctive relief, and whether the questions raised were hypothetical or sought an advisory opinion. Specifically, the Court had to determine if the negotiation of an ILUA, and the validity of potential petroleum leases in relation to it, constituted a "matter arising under" the Native Title Act, thereby conferring jurisdiction on the Federal Court under s 213(2) of that Act. The Court also considered the scope of its own original jurisdiction under s 75(v) of the Constitution and its power to award costs.

The High Court found that the Federal Court's primary judge and the Full Court had erred in concluding that there was no matter before them, that the plaintiffs lacked standing, that the application was merely for an advisory opinion, and that the Federal Court lacked jurisdiction. The Court reasoned that the validity of the ATP and the potential grant of a petroleum lease were directly relevant to the bargaining position of the native title claimants in the ILUA negotiations, and therefore constituted a "matter arising under" federal law. The Court noted that mistakenly denying jurisdiction is a jurisdictional error attracting a writ of certiorari. The High Court quashed the decisions of the Federal Court and dismissed the application for a writ of mandamus. The first, second, and third defendants were ordered to pay the costs of the applicants in the Federal Court proceedings and in the High Court.
