Doyle's Farm Produce Pty Ltd v Murray Darling Basin Authority (No 2)

The dispute in *Doyle's Farm Produce Pty Ltd v Murray Darling Basin Authority (No 2)* concerned allegations of negligence against the Murray Darling Basin Authority (the Authority) and its delegates for releasing water that allegedly caused damage to the plaintiffs' lands. The matter came before the Court of Appeal of New South Wales, with Bathurst CJ, Bell P, and Leeming JA presiding. The Authority had pleaded defences under Part 5 of the *Civil Liability Act 2002* (NSW), asserting it was a "public or other authority" within the meaning of section 41 of that Act.

The primary legal issues before the Court of Appeal were whether the Authority, or its delegates, constituted a "public or other authority" as defined by section 41 of the *Civil Liability Act 2002* (NSW). A further question, contingent on an affirmative answer to the first, was whether the application of Part 5 of the Act would be inconsistent with federal law, specifically section 64 of the *Judiciary Act 1903* (Cth) or section 109 of the Commonwealth Constitution. These questions were reserved on agreed facts and removed to the Court of Appeal for determination.

The Court of Appeal determined that neither the Authority nor its delegates qualified as a "public or other authority" under section 41 of the *Civil Liability Act 2002* (NSW). Consequently, the subsequent constitutional question regarding inconsistency with federal law did not arise. The Court dismissed a summons seeking leave to appeal and ordered the defendants to pay the plaintiffs' costs of the separate questions.
