Hamersley Iron Pty Ltd v National Competition Council

Hamersley Iron Pty Ltd sought a judicial review of a decision made by the National Competition Council to increase the royalty rate for iron ore mining in Western Australia. The case was heard in the Federal Court of Australia. The central legal issue was whether the Council's decision to increase the royalty rate was lawful and whether the applicant was entitled to a declaration and an injunction to prevent the increased royalty rate from taking effect.

The Court examined the statutory framework governing the Council's decision-making process, including the appropriate considerations it should have taken into account. The Court held that the Council's decision was flawed because it had not appropriately considered the potential impact of the increased royalty rate on the applicant's business. The Court found that the Council had failed to take into account relevant economic factors and had not adequately justified the increased royalty rate. The Court also held that the applicant was entitled to the declaration and injunction sought.

In light of the above, the Court ordered that the second, third, fourth, fifth, sixth and seventh respondents were to pay 73% of the applicant's costs, including all reserved costs, and the costs of and incidental to the first respondent's participation in the proceeding.
