Marshall v Director-General, Department of Transport B52/2000

The High Court of Australia considered an appeal by Mr Marshall against a decision of the Director-General of the Department of Transport. The dispute concerned the validity of a notice issued by the Director-General under section 134 of the *Road Transport (General) Act 1999* (NSW), which required Mr Marshall to undergo a medical examination. Mr Marshall contended that the notice was invalid because it was issued by an officer who had not been properly delegated the necessary authority by the Director-General.

The central legal issue before the High Court was whether the delegation of power to issue a notice under section 134 of the *Road Transport (General) Act 1999* (NSW) was validly exercised. Specifically, the Court had to determine if the officer who issued the notice possessed the requisite authority, either through a proper delegation from the Director-General or by virtue of their office. This involved an examination of the principles of administrative law concerning the delegation of statutory powers and the requirements for valid delegation.

The High Court held that the delegation of power was invalid. The Court reasoned that the Director-General had not made a proper delegation of the power to issue a notice under section 134. The purported delegation was found to be defective, as it did not comply with the requirements of the relevant legislation and administrative law principles governing delegation. Consequently, the notice issued to Mr Marshall was deemed to be invalid.

The High Court allowed the appeal and quashed the notice issued by the Director-General.
