Mine Subsidence Board v Wambo Coal Pty Ltd

The Mine Subsidence Board (appellant) appealed to the Court of Appeal of New South Wales against a decision of Lloyd J in the Land and Environment Court concerning claims for compensation under the *Mine Subsidence Compensation Act 1961* (NSW). The dispute arose from Wambo Coal Pty Ltd (respondent) seeking compensation for works it undertook to prevent or mitigate damage to its mine from anticipated subsidence caused by the appellant's mining operations.

The primary legal issue before the Court of Appeal was whether the respondent was entitled to claim compensation for works carried out to prevent or mitigate damage from anticipated mine subsidence, as opposed to damage that had already occurred. This involved the interpretation of sections 12, 12A, 12B, and 13A of the *Mine Subsidence Compensation Act 1961*.

The Court of Appeal determined that the Act, particularly in light of amendments, permitted claims for compensation for works undertaken to prevent or mitigate damage from anticipated subsidence. The court reasoned that the legislative intent behind the amendments was to broaden the scope of compensable damage, encompassing proactive measures taken by mine owners to address foreseeable subsidence impacts. Consequently, the court set aside the previous answers given by Lloyd J and substituted new answers that affirmed the respondent's entitlement to claim compensation for such preventative works. The proceedings were remitted to the Land and Environment Court for further determination.
