Nicholls & Anor v The City of Tea Trea Gully

The applicants, Geoffrey Douglas Nicholls and another, sought special leave to appeal to the High Court of Australia against a decision concerning a proposed amendment to a Council's zoning scheme. The dispute arose when the City of Tea Tree Gully, the first respondent, proposed a scheme to amend zoning within its area to facilitate commercial development of its own land. The applicants contended that the Council, in proposing this scheme and subsequently hearing submissions from affected parties, including themselves, acted in a manner that breached the rules of natural justice. The second respondent was the Minister for Environment.

The central legal issue before the High Court was whether the rules of natural justice should apply to a statutory authority, such as a local council, when it proposes a scheme that would benefit its own land, and then proceeds to hear submissions from those who oppose the scheme and whose property is affected. The applicants argued that the Council's dual role as proponent and quasi-adjudicator of submissions created a perception of bias and necessitated procedural fairness. They further contended that the legislation provided an alternative procedure, under section 41 of the relevant Act, whereby the Council could have requested the Minister to prepare a supplementary scheme, thereby avoiding the situation where the Council heard and determined submissions relating to its own proposal.

The applicants' argument was that the Council's process involved a hearing and a decision-making function regarding submissions, which attracted the rules of natural justice, irrespective of whether the overall process could be characterised as legislative or political. They relied on the principle that the rules of natural justice do not strictly depend on a classification of function into judicial, administrative, or legislative categories, but rather on the substance of what is occurring, particularly the hearing and determination of submissions. The applicants pointed to the case of *FAI v Winneke* as support for the proposition that even bodies involved in a broader political or legislative process may be subject to natural justice requirements in certain aspects of their function.
