Corcoran v Tyre Marketers Australia

The appellant, Corcoran, appealed a decision concerning a workers compensation claim for a back injury that subsequently worsened, complicated by a pre-existing degenerative spinal condition. The primary dispute revolved around whether the appellant could revoke an election to claim compensation for permanent loss, pursuant to section 151A(5)(c) of the *Workers Compensation Act 1987*. The appellant also contended that the election did not extend to a neck injury.

The court was required to determine two main legal issues. Firstly, whether the primary judge erred in finding, based on the medical evidence, that there was reasonable cause to believe further deterioration of the appellant's condition would occur at the time of the election. Secondly, the court had to consider the scope of the appellant's election, specifically whether it encompassed a neck injury.

The court's reasoning was heavily influenced by the High Court's decision in *State of New South Wales v Taylor*. The majority in *Taylor* held that section 151A(5)(c) requires the court to assess whether it would be unreasonable to believe, based on the evidence before the court at the time of election, that further deterioration would occur. The onus rests on the applicant for revocation to prove a negative, that there was no reasonable cause to believe in further deterioration. This involves examining all relevant evidence concerning the medical condition and its prognosis at the time of election, including medico-legal opinions. The court's view of the evidence, not the injured person's belief, is decisive. If the evidence admits of two reasonable but opposing conclusions regarding further deterioration, the applicant fails to discharge the onus. The court noted that "no reasonable cause to believe" means "no cause for reasonably believing".
