Mirvac Queensland Pty Limited v Dunworth

The High Court of Australia considered an appeal by Mirvac Queensland Pty Limited against a decision of the Supreme Court of Queensland. The dispute concerned the interpretation of a development approval granted by the Brisbane City Council for a residential development. The core of the disagreement lay in whether the development approval permitted the construction of a particular type of building, specifically a multi-storey residential building, on the land.

The High Court was required to determine the proper construction of the development approval, particularly the meaning and effect of the conditions attached to it. The central legal question was whether the conditions imposed by the Council, when read in conjunction with the planning scheme provisions, restricted the type of residential development that could be undertaken on the site to a single dwelling house, or whether they allowed for the construction of a multi-storey residential building as proposed by Mirvac.

The Court analysed the relevant provisions of the *Integrated Planning Act 1997* (Qld) and the Brisbane City Plan. It applied principles of statutory interpretation, considering the ordinary meaning of the words used in the development approval and the conditions, as well as the context provided by the planning scheme. The Court found that the conditions, when read as a whole and in light of the planning scheme's objectives, did not impose a restriction limiting the development to a single dwelling house. Instead, the approval, as granted, permitted the construction of a multi-storey residential building, subject to compliance with the specified conditions.

The High Court allowed the appeal, setting aside the orders of the Supreme Court of Queensland.
