BHP Billiton Iron Ore Pty Ltd v Construction, Forestry, Mining and Energy Union of Workers

The matter before the court involved an appeal by BHP Billiton Iron Ore Pty Ltd against an order made by the Fair Work Commission. The dispute centred around the Commission's decision to grant an interim injunction to the Construction, Forestry, Mining and Energy Union of Workers, prohibiting BHP Billiton from implementing certain operational changes. The case was heard in the Full Court of the Federal Court of Australia.

The central legal issues were whether the appeal should be stayed pending its determination and what principles should guide the court in deciding whether to grant a stay. The appeal turned on the unique facts of the case, and the court was tasked with determining whether the balance of convenience favoured a stay, and whether a stay would cause undue prejudice to the parties.

The court considered the principles governing the stay of proceedings, including the need to balance the interests of both parties and the potential impact on the outcome of the appeal. It was noted that the principles were not rigid and had to be applied flexibly to the specific circumstances of the case. The court found that, given the particular facts and the potential for significant disruption to BHP Billiton's operations if the injunction were to remain in place, the balance of convenience favoured a stay. However, the court also found that the stay should not cause undue prejudice to the union, and so ordered a partial stay pending the determination of the appeal.

The court's final orders included a partial stay of the injunction, allowing BHP Billiton to implement the operational changes that were subject to the injunction, while certain aspects of the injunction remained in effect until the appeal was determined. The union was given an opportunity to make submissions on the terms of the stay.
