Puntoriero v Water Administration Ministerial Corporation

The High Court of Australia considered an appeal by Mr Puntoriero against the Water Administration Ministerial Corporation (WAMC) concerning the WAMC's decision to refuse Mr Puntoriero's application for a water access licence. Mr Puntoriero sought to convert his existing water allocation, which was tied to a specific parcel of land, into a licence that would allow him to trade water independently of that land. The dispute centred on the interpretation and application of the *Water Management Act 2000* (NSW) and its associated regulations, particularly concerning the conditions under which such conversions could be granted.

The primary legal issue before the High Court was whether the WAMC had erred in law by refusing Mr Puntoriero's application for a water access licence. This required the Court to determine the proper construction of the relevant provisions of the *Water Management Act 2000* (NSW) and the *Water Management (General) Regulation 2004* (NSW), specifically those provisions governing the conversion of existing water allocations to tradeable licences and the discretion vested in the WAMC to grant or refuse such applications. The Court also had to consider whether the WAMC had taken into account irrelevant considerations or failed to take into account relevant considerations in its decision-making process.

The High Court held that the WAMC had acted unlawfully in refusing Mr Puntoriero's application. The Court reasoned that the WAMC had misinterpreted the statutory scheme by treating the conversion of water allocations to licences as a discretionary power that could be exercised for reasons unrelated to the statutory criteria. Instead, the Court found that the Act and Regulation prescribed specific conditions for conversion, and if these conditions were met, the WAMC was obliged to grant the licence, subject to any overriding public interest considerations that were properly within its purview. The Court emphasised that the WAMC's discretion was not unfettered and must be exercised in accordance with the purposes of the Act, which included facilitating the efficient and sustainable management of water resources and enabling water trading.

The High Court allowed the appeal, set aside the decision of the WAMC, and remitted the matter to the WAMC with a direction to grant Mr Puntoriero's application for a water access licence.
