Alinta LGA Ltd v Mine Subsidence Board

Alinta LGA Ltd (formerly The Australian Gas Light Company) appealed to the High Court of Australia against a decision of the Mine Subsidence Board. The dispute concerned a claim for compensation from the statutory fund established under the *Mine Subsidence Compensation Act 1961* (NSW) for the cost of works undertaken to prevent damage to a pipeline from mine subsidence. The Board had refused to entertain the claim on the basis that the pipeline was erected without the required approval, and therefore, a certificate under section 15(5)(b) of the Act could not be issued.

The central legal issue before the High Court was whether the Board's refusal to entertain the claim, due to the alleged absence of jurisdictional facts, was an appealable decision under section 12B(b) of the *Mine Subsidence Compensation Act 1961* (NSW), which confers a right of appeal to the Land and Environment Court against "the decision of the Board as to the amount of the payment from the Fund". Alternatively, the question was whether such a refusal was amenable only to judicial review in the Supreme Court of New South Wales. The High Court also considered whether the Land and Environment Court possessed the jurisdiction to hear and determine the appeal against the Board's decision, given the breadth of its powers under section 39(3) of the *Land and Environment Court Act 1979* (NSW) to conduct a de novo rehearing.

The High Court held that the refusal by the Board to entertain the claim was not a decision "as to the amount of the payment from the Fund" within the meaning of section 12B(b). Instead, it was a preliminary determination that the jurisdictional prerequisites for a claim to be entertained had not been met. Consequently, the appeal to the Land and Environment Court under section 12B(b) was not competent. The Court reasoned that the Land and Environment Court's jurisdiction under section 16 and 19(f) of the *Land and Environment Court Act 1979* (NSW) was confined to appeals of the type specified in section 12B of the *Mine Subsidence Compensation Act 1961* (NSW). The broad powers of rehearing under section 39(3) did not extend the Court's appellate jurisdiction beyond what was conferred by the specific appeal provisions.

The appeal was dismissed with costs.
