Re Australian Railways Union; Ex Parte Public Transport Corporation

The High Court of Australia considered an application for a writ of prohibition by the Public Transport Corporation against the Australian Railways Union. The dispute concerned the validity of certain industrial action taken by the Union, which the Corporation alleged was unlawful.

The central legal issue before the Court was whether the industrial action undertaken by the Australian Railways Union was protected by the provisions of the relevant industrial relations legislation, specifically concerning the definition of "industrial dispute" and the scope of lawful industrial action. The Court also had to determine the extent to which the legislation permitted industrial action that might otherwise be considered a breach of contract or tortious.

The Court's reasoning focused on the interpretation of the statutory framework governing industrial relations. It analysed the concept of an "industrial dispute" as defined by the legislation, emphasising that it encompassed a broad range of disagreements arising out of the relationship of employer and employee. The Court held that the industrial action in question, being a response to a dispute concerning terms and conditions of employment, fell within the statutory definition. Furthermore, the Court affirmed the principle that legislation conferring protection on industrial action is intended to permit conduct that would otherwise be unlawful, provided it is undertaken in furtherance of a genuine industrial dispute and complies with the statutory requirements. The Court distinguished between conduct that is protected by the legislation and conduct that remains unlawful.
