Redland City Council v Kozik

The High Court of Australia considered an appeal by Redland City Council against respondents who had paid special charges levied by the Council. The dispute arose because the resolutions purporting to levy these special charges were found to be invalid. The respondents had paid these charges as part of their rate notices, and subsequently sought the return of the money paid.

The central legal issues before the Court were whether the regulations providing for the return of special charges applied when the resolution levying those charges was invalid, and whether the Council had a defence to a claim for restitution based on unjust enrichment, particularly given that the funds had been spent on works conducted on waterways adjacent to the respondents' land and that the Council was statutorily obliged to conduct these works. The Court also considered the applicability of an extended defence of change of position or fiscal chaos for taxing authorities.

The High Court reasoned that the regulations concerning the return of special charges were applicable even where the initial resolution was invalid, as the purpose of the regulations was to address situations where special charges did not apply to the land. Regarding the defence of unjust enrichment, the Court rejected the notion of an extended defence of change of position or fiscal chaos for taxing authorities, citing international jurisprudence and fundamental questions of fairness to taxpayers. The Court found that the Council had not established a defence to the respondents' claim for restitution.

Consequently, the High Court dismissed the Council's appeal with costs. Special leave was granted to the respondents to cross-appeal, but this cross-appeal was also dismissed with costs.
