Minister for the Environment v Packham & Anor; Wheelhouse v Packham

These matters concerned an application for special leave to appeal to the High Court of Australia from a decision of the Court of Appeal. The applicants, the Minister for the Environment and another party, sought to challenge the Court of Appeal's interpretation of section 151(1)(f) of the National Parks and Wildlife Act. The respondents were Dr Packham and Mr Wheelhouse.

The central legal issue before the High Court was the proper construction of the ministerial power to grant licences to occupy or use lands within a national park under section 151(1)(f) of the National Parks and Wildlife Act. Specifically, the Court of Appeal had interpreted this power as being confined to the grant of licences whose purpose, from the licensee's perspective, supported or was conducive to the national park's objectives. The applicants contended that this interpretation was erroneous and had a significant detrimental impact on the practical application of the legislation, particularly concerning licences for essential infrastructure like pipelines that cross national parks.

The applicants argued that the Court of Appeal erred by confusing the requirement that statutory powers must conform to the purposes of the legislation with the proposition that each power must have a specific, narrowly defined purpose that necessarily aligns with the primary objectives of maintaining national parks. They submitted that the power to grant licences was not so circumscribed and that the Court of Appeal's majority had fallen into error by imposing an overly restrictive purpose on the statutory power. The applicants' submission was that the power was broader and not limited to uses that exclusively enhanced the enjoyment or maintenance of the national park itself.
