Commonwealth v Matheson

The Commonwealth appealed to the High Court of Australia from a decision of the District Court of New South Wales concerning a workers' compensation claim brought by George Matheson, a federal employee. Matheson had sustained injuries to both his left and right legs in a single accident at work. The dispute centred on the proper application of the Commonwealth Employees' Compensation Act 1930-1950, specifically sections 9 and 12, and the relevant schedules, to determine the compensation payable for Matheson's injuries.

The primary legal issue before the High Court was whether section 12 of the Act, which provides for lump sum compensation for specific scheduled injuries, was applicable even when an employee sustained multiple injuries in the same accident, including injuries not listed in the Third Schedule. The court was required to determine if the application of section 12 was confined only to cases where the entirety of the accident's consequences fit a scheduled injury, or if it applied to any identifiable scheduled injury sustained, irrespective of other concurrent injuries.

The High Court reasoned that the application of section 12 and its Third Schedule is not limited to situations where the total effect of an accident precisely matches a scheduled injury. Instead, if an accident causes an injury that results in a loss described in the schedule or in subsections (5) or (6) of section 12, and the other conditions of that section are met, a lump sum payment is mandated. It is irrelevant if the same accident also caused another injury, whether that other injury is also scheduled, compensable under section 9 and the First Schedule, or not compensable at all. The court found that the District Court judge had erred in his interpretation by not applying section 12 to the injury to Matheson's left leg, which resulted in a significant loss of efficient use.

Consequently, the High Court allowed the appeal, setting aside the District Court's award. It ordered that Matheson receive a lump sum payment under the Third Schedule for the permanent loss of efficient use of his left leg, calculated at 55% of the scheduled amount, totalling £515 12s. 6d. Additionally, compensation for the injury to his right hip was to be paid under the First Schedule, based on a 15% incapacity for work, as agreed by the parties.
