BHP Billiton Mitsui Coal Pty Ltd v Isdale

The case of BHP Billiton Mitsui Coal Pty Ltd v Isdale involved a dispute regarding the application for additional surface area in relation to the applicant's mining leases. The application was objected to by the second respondents. The matter was referred to the Land Court under the Mineral Resources Act 1989 (Qld) and the Environmental Protection Act 1994 (Qld). The applicant subsequently sought judicial review of the Land Court's decision. The primary legal issue before the court was whether the decision made by the Land Court was reviewable under the Judicial Review Act 1991 (Qld).

The court held that the decision of the Land Court was reviewable as it was of an administrative character. The court found that the Land Court was acting in an advisory capacity, providing advice to the Minister who would make the ultimate decision on the mining lease application. The court concluded that the Land Court's role was to make a recommendation rather than to determine existing or future rights and obligations. Consequently, the function exercised by the Land Court was administrative in nature. The court also found that the Land Court erred in law by applying rules 4 and 13 of the Land Court Rules 2000 (Qld) as the court was acting in an advisory capacity, and there was no "proceeding" for the purpose of those rules.

The court set aside the decision of the Land Court, declaring that rule 13 of the Land Court Rules 2000 (Qld) did not apply to the consideration of the matters referred to the Land Court. The court also ordered that the decision of the Land Court made on 9 December 2014 be set aside. No appeal was to be made to the Land Appeal Court as the decision of the Land Court member was not an exercise of judicial power.
