BHP Billiton Iron Ore Pty Ltd v National Competition Council

BHP Billiton Iron Ore Pty Ltd (BHP) sought judicial review of a decision by the National Competition Council (NCC) to recommend to the Treasurer that BHP's proposed access undertaking for its Pilbara iron ore rail infrastructure not be declared. The dispute concerned whether the NCC had erred in law in its assessment of the undertaking. The matter was heard by the Full Federal Court of Australia.

The primary legal issue before the Full Federal Court was whether the NCC had acted unlawfully in making its recommendation. Specifically, the court was required to determine whether the NCC had misinterpreted or misapplied the relevant provisions of the *Competition Policy Reform (Western Australia) Act 1996* (WA) and the *Trade Practices Act 1974* (Cth) (now the *Competition and Consumer Act 2010* (Cth)) in its consideration of BHP's undertaking. This involved examining whether the NCC had properly assessed whether the undertaking would be a sufficient substitute for declaration of the infrastructure, and whether it had given adequate reasons for its conclusion.

The Full Federal Court found that the NCC had failed to provide adequate reasons for its recommendation, a failure that amounted to an error of law. The court held that the NCC's decision-making process, as evidenced in its reasons, did not demonstrate a proper understanding or application of the statutory criteria for assessing an access undertaking. The court emphasised the importance of clear and comprehensive reasons in administrative decision-making, particularly when such decisions have significant commercial implications.

The Full Federal Court ordered that the NCC's decision be quashed and remitted to the NCC for reconsideration according to law.
