Attorney General of New South Wales v World Best Holdings Ltd

The Attorney General of New South Wales (the appellant) appealed to the Court of Appeal of New South Wales against a decision concerning the validity of a determination made by the Retail Leases Division of the Administrative Decisions Tribunal. The dispute arose from claims of unconscionable conduct under the *Retail Leases Act 1994* (NSW), where the validity of the Tribunal's constitution and decision was challenged due to the participation of non-judicial members.

The primary legal issues before the Court of Appeal were whether the Tribunal was validly constituted when it made its decision, and if not, whether that invalidity was cured by the retrospective operation of section 81(3) of the *Administrative Decisions Tribunal Act 1997* (NSW). This involved considering the effect of a retrospective statutory provision on pending proceedings, particularly those subject to an appeal by way of rehearing.

The Court of Appeal, comprising Spigelman CJ, Mason P, and Tobias JA, reasoned that the participation of non-judicial members in the Tribunal did not render its decision invalid. The Court applied the principles of statutory interpretation, finding that section 81(3) of the *Administrative Decisions Tribunal Act 1997* operated retrospectively to validate the constitution and decisions of the Tribunal, even in respect of proceedings that were ongoing at the time the amending legislation came into force. The Court held that the Tribunal was validly constituted and its decision was therefore lawful.

Leave to appeal was granted, but the appeal was ultimately dismissed. The appellant was ordered to pay the first respondent's costs, with no order as to the second respondent's costs. Certain orders made by Patten AJ were also varied and set aside.
