State of New South Wales v Taylor

The High Court of Australia heard an appeal from the Court of Appeal of New South Wales concerning the interpretation of section 151A(5)(c) of the *Workers Compensation Act 1987* (NSW). The dispute arose when a worker, who had previously settled a claim for permanent loss compensation and irrevocably elected to forgo damages, sought to revoke that election to commence proceedings for damages. This revocation was subject to the condition in section 151A(5)(c) that it would be unreasonable for a person in the worker's position to believe that further deterioration of their condition would probably occur.

The central legal issue before the High Court was the proper construction of section 151A(5)(c), specifically the meaning of "no reasonable cause to believe" and the temporal and evidentiary basis for such a belief. The Court was required to determine whether the criterion for revoking an election under this provision relates to the subjective belief of the injured worker or an objective assessment of the evidence available at the time of the election regarding the likelihood of further deterioration.

The High Court, in allowing the appeal, held that the construction of section 151A(5)(c) adopted by the majority in the Court of Appeal was erroneous. The Court clarified that the provision operates by reference to the absence of reasonable cause to believe that further deterioration would occur, assessed objectively by reference to the evidence concerning the applicant's condition at the time of the election and expert opinion on the medical prognosis at that time. The subjective knowledge or belief of the applicant was deemed irrelevant. The Court found that it was open to the courts below to conclude that no reasonable cause was shown to believe that the deterioration which occurred would happen, and therefore the worker's application for revocation should have failed. The orders of the Court of Appeal were set aside, and the appeal to that court was dismissed.
