Tepko Pty Limited & Ors v Water Board

Tepko Pty Limited and others (the appellants) brought proceedings against the Water Board (the respondent) seeking declarations and injunctions concerning the respondent's alleged breach of contract and misrepresentation in relation to the supply of water. The case was heard by the High Court of Australia.

The central legal issues before the High Court were whether the Water Board had breached its contractual obligations to supply water to the appellants and whether the Water Board had made representations that were misleading or deceptive in contravention of the Trade Practices Act 1974 (Cth). The appellants also sought to establish that the Water Board had acted in a manner that constituted an abuse of its statutory powers.

The High Court considered the terms of the contract between the parties and the relevant statutory framework governing the Water Board's operations. The Court analysed the evidence presented to determine if the Water Board's actions amounted to a breach of contract or a contravention of the Trade Practices Act. The Court also examined the scope of the Water Board's statutory powers and whether its conduct fell outside those powers. The reasoning focused on the interpretation of contractual provisions and the application of consumer protection legislation to statutory authorities.

The High Court dismissed the appeal, finding that the Water Board had not breached its contractual obligations and had not engaged in misleading or deceptive conduct. The Court also held that the Water Board had acted within its statutory powers.
