Council of the Municipality of Botany v Federal Airports Corporation

The parties to this matter before the High Court of Australia were the Municipality of Botany and the Federal Airports Corporation. The dispute concerned the interpretation of regulations made by the Federal Airports Corporation and their interaction with State laws. Specifically, the Municipality of Botany was arguing that certain State laws remained applicable despite the Federal Airports Corporation's regulations.

The central legal issue before the Court was whether the Federal Airports Corporation's regulations, by their express terms, intended to exclude the application of specific State laws. This involved determining the proper approach to construing Commonwealth legislation that purports to displace State laws, particularly when the Commonwealth legislation refers to the State provisions.

The Court, through the submissions of counsel referencing previous High Court decisions, considered the principle that where Commonwealth legislation expressly states an intention to be an exhaustive declaration of the law on a particular subject, it will be given effect. Counsel referred to *Wenn v Attorney-General* and *Australian Coastal Shipping Commission v O'Reilly* to illustrate that the Parliament can make its intention clear either by inference from the nature and scope of the legislation or by express statement. The argument presented was that the Federal Airports Corporation regulations had expressly stated their intention to exclude certain State provisions, thereby preventing their application.
