The planning authorities (a local government and Western Australian Planning Commission) rushed through an amendment to the Scheme which redefined ‘Service Station’ to include the ‘sale of goods of an incidental or convenience nature.’ Because of this change, the proposed use was classified as ‘not permitted unless the [local government] has exercised its discretion by granting planning approval’ (Amendment). The Tribunal, standing in the shoes of the local government in the review proceedings, ignored the Amendment and approved the application.
The Supreme Court at first instance held that the classification of the use at the preliminary hearing gave the Developer an ‘accrued right’ to have the application determined in accordance with the Preliminary Decision
On appeal to the Court of Appeal it was held that the Preliminary Decision did not have binding effect because at the preliminary hearing it is not the role of the Tribunal to make a binding legal determination.
The decision is consistent with the well-established principle of Australia planning law: a planning application is to be determined on the basis of the law as it stands at the time of the determination, whether by an original decision maker, on review in the Tribunal or on appeal to a court.
