Electricity Networks Corporation Trading As Western Power v Herridge Parties and related matters

The High Court of Australia considered the dispute between Electricity Networks Corporation trading as Western Power and Mr. Herridge. The case concerned the interpretation and application of the *Workers' Compensation and Rehabilitation Act 1981* (WA) (the Act) in relation to a claim for compensation by Mr. Herridge, a former employee of Western Power, for a work-related injury.

The central legal issue before the High Court was whether Mr. Herridge's claim for compensation was barred by the limitation period prescribed by the Act. Specifically, the Court had to determine whether the "discovery" of the injury, for the purposes of the limitation period, occurred at the time Mr. Herridge first experienced symptoms or at the time he was formally diagnosed with the condition. This involved an examination of the meaning of "injury" and "disease" as defined within the Act and how these terms interacted with the statutory time limits for making a claim.

The High Court reasoned that the Act's provisions regarding the commencement of the limitation period for diseases were intended to provide a reasonable opportunity for workers to make claims once they became aware of the connection between their condition and their employment. The Court held that the limitation period for Mr. Herridge's claim began to run not from the first onset of symptoms, but from the date he knew, or ought reasonably to have known, that his condition was an injury arising out of or in the course of his employment. This interpretation emphasised the importance of the worker's knowledge and understanding of the causal link between their work and their illness.

The High Court allowed the appeal, setting aside the decision of the Court of Appeal and remitting the matter to the District Court of Western Australia for determination according to law.
