Queensland Wire Industries Pty Ltd v Broken Hill Proprietary Co Ltd

Queensland Wire Industries Pty Ltd (QWI) sought an injunction and damages against Broken Hill Proprietary Co Ltd (BHP) for alleged breaches of the restrictive trade practices provisions of the *Trade Practices Act 1974* (Cth). QWI, a manufacturer of wire fencing, alleged that BHP, a dominant supplier of steel products including steel rods, had refused to supply steel rods to QWI on the same terms as it supplied them to its own subsidiary, John Lysaght (Australia) Ltd, which also manufactured wire fencing. The dispute concerned BHP's pricing and supply policies for steel rods. The case was heard by the High Court of Australia.

The central legal issue before the High Court was whether BHP's conduct in refusing to supply steel rods to QWI on terms no less favourable than those offered to its subsidiary, John Lysaght (Australia) Ltd, constituted a contravention of section 46 of the *Trade Practices Act 1974* (Cth). Specifically, the court had to determine if BHP had taken advantage of its dominant position in the market for steel rods for the purpose of preventing QWI from engaging in competitive conduct in the market for wire fencing.

The High Court, in a joint judgment, found that BHP had indeed contravened section 46 of the Act. The court held that BHP, by using its monopoly power in the steel rod market to disadvantage a competitor in the wire fencing market, had engaged in conduct that was prohibited. The reasoning focused on the concept of "taking advantage" of a dominant position, which the court interpreted broadly to include conduct that would not have occurred but for the existence of that dominance. The court emphasised that the purpose of the provision was to prevent corporations from using their market power in one area to stifle competition in another.

Consequently, the High Court ordered that BHP was liable for contravening section 46 of the *Trade Practices Act 1974* (Cth). The matter was remitted to the Federal Court of Australia for the determination of appropriate remedies, including the granting of an injunction and damages.
