Re Keely; Ex Parte Ansett Transport Industries (Operations) Pty Ltd

In *Re Keely; Ex Parte Ansett Transport Industries (Operations) Pty Ltd*, Dawson J of the High Court of Australia considered an application for a writ of prohibition. The applicant, Ansett Transport Industries (Operations) Pty Ltd, sought to prohibit the respondent, Mr. Keely, a magistrate, from proceeding with a hearing concerning alleged breaches of the *Conciliation and Arbitration Act 1904* (Cth). The alleged breaches involved Ansett's failure to pay certain employees overtime rates as required by an award.

The central legal issue before Dawson J was whether the magistrate had jurisdiction to hear and determine the proceedings. Specifically, the court had to determine whether the relevant award, which prescribed overtime rates, was valid and binding at the time of the alleged breaches, and whether the proceedings were properly instituted under the *Conciliation and Arbitration Act 1904*. Ansett contended that the award was invalid due to a failure to comply with certain procedural requirements of the Act during its making.

Dawson J reasoned that the validity of the award was a question that the magistrate had jurisdiction to determine as part of the proceedings before him. His Honour held that the magistrate was not acting in excess of his jurisdiction by entertaining the charge, even if the charge might ultimately fail due to the award's invalidity. The principle applied was that a court or tribunal has jurisdiction to hear and determine all questions incidental to the main question which it has jurisdiction to try. The application for prohibition was therefore dismissed.
