Arnold v Minister Administering the Water Management Act 2000 (No 5)

The applicants in Arnold v Minister Administering the Water Management Act 2000 (No 5) sought a declaration that the cancellation of their conjunctive water use rights was ineffective due to the Minister's failure to comply with certain statutory provisions. They also sought an injunction and a declaration that the Minister's decision to cancel their rights was invalid. The matter was heard in the Supreme Court of Victoria.

The primary legal issue before the Court was whether the applicants' claim of ineffectual cancellation of conjunctive water use rights, based on the Minister's non-compliance with certain statutory provisions, was properly pleaded and particularised. Additionally, the Court needed to determine whether the applicants' claim was justiciable and whether the Court should entertain the unpleaded discretionary defence that relief should not be granted on the ground that it works disproportionate injustice to third parties.

The Court found that the applicants' claim was not properly pleaded or particularised, as they had not adequately outlined the specific statutory provisions that the Minister failed to comply with, nor had they provided sufficient detail about the nature of the non-compliance. As a result, the Court declined to entertain the claim of ineffectual cancellation of conjunctive water use rights. However, the Court did not dismiss the applicants' claim outright and instead indicated that the question of whether the unpleaded discretionary defence should be entertained and, if so, whether it should be upheld, should be determined separately at a further trial if the applicants were found to be otherwise entitled to the declaratory relief they sought. In this way, the Court provided a path for the applicants to potentially re-plead and particularise their claims, should they choose to do so.

ORDERS:
(1) The applicants' claim of ineffectual cancellation of conjunctive water use rights because of non-compliance with ss 116C and 117H of the Water Act 1912 and consequential judicial review grounds were not pleaded or properly particularised and the Court declines to entertain them. (2) The decision of the question whether the Court should entertain the unpleaded discretionary defence that relief not be granted on the ground that it works disproportionate injustice to third parties, and, if so, the question whether that defence should be upheld, be determined separately from and after any other question in the present trial at a further trial in the proceedings if the applicants are adjudged to be otherwise entitled to the declaratory relief as to invalidity that they seek.
