Development Assessment Commission v A & V Contractors Pty Ltd

The Development Assessment Commission appealed to the Supreme Court of South Australia against a decision of the Environment, Resources and Development Court (ERD Court). The dispute concerned whether the proposed development by A & V Contractors Pty Ltd constituted a continuation of an existing use of land or a change of use. If it was a change of use, the Commission argued it was a non-complying development, and therefore not a "reasonable development of a pre-existing use" that would entitle the respondent to a merits assessment before the Commission and an appeal to the ERD Court. The central question for the Supreme Court was whether the ERD Court had jurisdiction to hear the appeal and, if so, whether it had erred in law in its disposition of the matter.

The legal issues before the Supreme Court were twofold. Firstly, it had to determine whether the proposed development by A & V Contractors Pty Ltd was an existing use or a change of use. Secondly, if it was a change of use, the Court needed to ascertain whether that change of use was non-complying development. The Court was also required to consider whether, if the development was non-complying, it could be characterised as a "reasonable development of a pre-existing use" such that the ERD Court would have had jurisdiction to conduct a merits assessment and hear an appeal.

The Supreme Court allowed the appeal, finding that the proposed development constituted a change of use and that this change of use was non-complying development. The Court reasoned that the processing of building waste, as proposed, was an additional activity beyond the existing lawful use of the land as a landfill. This industrial processing was not incidental to the landfill operation and therefore required consent. The Court further held that the proposed development could not be considered a reasonable development of the pre-existing use, particularly given the evidence regarding the land's unsuitability for horticultural production. Consequently, the Supreme Court concluded that the ERD Court did not have jurisdiction to hear the appeal and, therefore, did not err in law in its disposition of the matter.
