Coal and Allied Operations Pty Ltd v Australian industrial Relations Commission

The High Court of Australia considered an appeal by Coal and Allied Operations Pty Ltd against orders made by the Full Court of the Federal Court of Australia. The dispute originated in the Australian Industrial Relations Commission (AIRC) concerning an industrial dispute between Coal and Allied Operations Pty Ltd and several unions regarding wages and conditions at a coal mine. Boulton J of the AIRC had terminated bargaining periods under the *Workplace Relations Act 1996* (Cth) due to the impact of industrial action. The unions appealed this decision to the Full Bench of the AIRC, which upheld the appeal and quashed Boulton J's orders. The Full Court of the Federal Court subsequently issued writs of certiorari and mandamus against the Full Bench, removing its decision and directing it to hear the appeal according to law. The High Court's task was to determine if the Full Court had erred in making these orders.

The central legal issues before the High Court were whether an erroneous finding of appealable error by an appellate tribunal, in its exercise of appellate jurisdiction, constitutes jurisdictional error, or if it is merely an error within jurisdiction. The Court also considered whether a misconception of the appellate function by the tribunal amounts to jurisdictional error, and if a discretionary decision can be challenged on the basis of an error in the decision-making process, whether demonstrated or inferred. Specifically, the Court had to determine the nature of an appeal to the Full Bench of the AIRC from a discretionary decision of a single member under s 45 of the *Workplace Relations Act 1996* (Cth), and whether such an appeal permitted the Full Bench to exercise its discretionary power afresh in the absence of appealable error, or if it was an appeal in the strict sense or by way of rehearing.

The High Court allowed the appeal, setting aside the orders of the Full Court of the Federal Court and dismissing the application for relief under s 75(v) of the Constitution. The Court reasoned that the Full Bench of the AIRC, in hearing the appeal from Boulton J's decision, was exercising its appellate jurisdiction. While the Full Bench's reasons for quashing Boulton J's orders may have been diverse and potentially flawed in their articulation of the grounds for appealable error, this did not amount to jurisdictional error. The Court held that an error in the exercise of appellate jurisdiction, even if it involves a misconception of the appellate function or an erroneous finding of appealable error, is generally an error within jurisdiction, not a jurisdictional error that would warrant judicial review under s 75(v) of the Constitution. The Full Court of the Federal Court had erred in treating the Full Bench's alleged errors as jurisdictional errors.
