Re The Honourable Justice Russell Peterson & Ors; Ex parte The Federated Engine Drivers and Firemens Association

The applicants, registered industrial organisations of employers, sought writs of mandamus, prohibition, and certiorari against Justice Russell Peterson, Deputy President Colin Polites, and Commissioner Pauline Griffin, who constituted the Australian Industrial Relations Commission. The dispute concerned the Commission's jurisdiction to make a finding of an industrial dispute under the relevant legislation.

The central legal issue before the High Court was whether the Australian Industrial Relations Commission had erred in law by failing to properly consider the definition of "industrial dispute" as it applied to the circumstances before it. Specifically, the applicants argued that the Commission, in upholding an appeal against a finding of dispute made by Commissioner Simmonds, had misunderstood or misapplied the requirement that the Commission must be satisfied that a situation is likely to give rise to an industrial dispute, rather than necessarily proving an existing interstate dispute.

The applicants contended that the legislation required the Commission to assess whether a situation was likely to lead to an industrial dispute, and that this assessment was a matter for the Commission itself. They argued that the Full Bench of the Commission had failed to appreciate this distinction when it overturned Commissioner Simmonds' initial finding. The applicants referred to section 4 of the relevant Act, which defines "industrial dispute" to include a situation likely to give rise to such a dispute, and section 101(1), which outlines the duty of the Commission in relation to alleged industrial disputes.

The High Court was therefore tasked with determining whether the Commission's decision demonstrated an error of law in its interpretation and application of the statutory definition of an industrial dispute and the procedural requirements for making such a finding.
