AAI Ltd trading as GIO v Moon

In this matter, AAI Limited, trading as GIO, sought judicial review of a decision made by a claims assessor under the Motor Accident Injuries Act 2017 (NSW). The central dispute involved the assessor's interpretation of certain sections of the Act, specifically sections 8.3(4), 8.10(3), and (4), and whether the claims assessor erred in law by permitting the payment of legal costs incurred by the claimant for statutory benefits, where those costs exceeded the maximum amount fixed by the regulations. The case was heard in the Supreme Court of New South Wales.

The primary legal issues before the court were whether the claims assessor erred in law by permitting the payment of legal costs that exceeded the statutory maximum and if there was any misinterpretation of the statutory provisions. Specifically, the court needed to determine if the claims assessor correctly applied the provisions of sections 8.3(4), 8.10(3), and (4) of the Act, and whether the term "incurred" in section 8.10(1) warranted a broader interpretation than the literal wording suggested. Additionally, the court examined the application of the maxim generalia specialibus non derogant to the statutory scheme.

The court found that the claims assessor did not err in law in their interpretation and application of the statutory provisions. The court held that the term "incurred" in section 8.10(1) should be given its ordinary and natural meaning, and the statutory framework did not permit the payment of legal costs exceeding the maximum set by the regulations. The court concluded that there was no jurisdictional error in the claims assessor's determination and dismissed the application for judicial review. As a result, the original decision of the claims assessor was upheld.
