Newcrest Mining v Industrial Relations Commission (NSW)

Newcrest Mining Limited sought a stay of proceedings before the Industrial Relations Commission of New South Wales (IRC). The dispute concerned the resolution of employment matters arising under an Australian Workplace Agreement (AWA) made under the Workplace Relations Act 1996 (Cth). Newcrest argued that the IRC lacked jurisdiction due to a potential inconsistency between the AWA and the Industrial Relations Act 1996 (NSW), and that the Commonwealth legislation, by virtue of section 109 of the Constitution, displaced the operation of the NSW Act.

The primary legal issue before the Court of Appeal was whether to grant an interlocutory stay of the IRC proceedings pending the determination of an application for prohibition. This required the court to consider the principles governing the grant of a stay, both under its inherent power and section 23 of the Supreme Court Act 1970 (NSW). Specifically, the court had to assess whether there was a sufficient likelihood of success on the merits of the prohibition application, which hinged on the question of constitutional inconsistency under section 109.

Bryson JA refused the stay. His Honour reasoned that the application for prohibition, which alleged a lack of State jurisdiction and constitutional inconsistency, was not sufficiently strong to warrant a stay of the IRC proceedings. The court applied the established principles for granting interlocutory stays, requiring a strong prima facie case or a serious question to be tried, balanced against the potential prejudice to the parties. In this instance, the court found that the threshold for granting a stay had not been met.

The Notice of Motion seeking the stay of proceedings was dismissed, and Newcrest Mining Limited was ordered to pay the costs of the application.
