Yates v Electricity Commission of New South Wales

This matter came before the High Court of Australia on an application for special leave to appeal. The applicant, Yates, sought to appeal a decision of the Court of Appeal of New South Wales. The respondent was the Electricity Commission of New South Wales. The core of the dispute concerned the application of amending legislation to the applicant's claim, which had been heard in the Court of Appeal.

The legal issues before the High Court revolved around whether the parties were aware of relevant amending legislation at the time of the original hearing and how this legislation, which restored common law rights in a limited way, should be applied. Specifically, the court considered whether the respondent had indicated an intention to file a further defence based on this legislation, and if not, whether it was open to the court to assume knowledge of the legislation by the parties. The court also had to consider the impact of the existing pleadings, particularly the statement of claim, on the ability to rely on the amending legislation.

The High Court expressed reservations about making assumptions regarding the parties' knowledge of the amending legislation, noting that such assumptions could introduce complexities not evident from the lower court's decision. The applicant argued that the respondent had not sought to rely on the amending legislation at the commencement of the hearing, and that the law at that stage, including the 1989 amendment, should have governed the proceedings. However, the court acknowledged that the statement of claim, referring to damage on 8 September 1987, presented a significant obstacle to the applicant's argument, despite evidence suggesting damage may have occurred prior to that date.
