The Commonwealth v Melbourne Harbour Trust Commissioners

The Commonwealth and the Acting Collector of Customs brought an action against the Melbourne Harbour Trust Commissioners concerning a bond executed by the Commissioners. The plaintiffs alleged the bond was taken pursuant to section 42 of the *Customs Act 1901-1916* as a Customs security under section 48, and alternatively, that the Commissioners had breached the conditions of the bond. The defendants demurred to the statement of claim, raising questions about the nature of the security the Customs authorities had the power to require.

The legal issues before the court included whether the bond constituted a valid Customs security under the *Customs Act*, whether it extended to goods not subject to duty, and whether the conditions within the bond, particularly those requiring the satisfaction of the Collector of Customs, were lawful. Further issues concerned the validity of the *Customs Regulations 1913* prescribing the form of the security, and whether section 48 of the *Customs Act*, which provided for the enforcement of such securities, usurped the judicial power of the Commonwealth. The court also considered whether the Commonwealth, as the obligee, had the right to sue on the bond.

The Full Court, by majority, overruled the demurrer. The Court reasoned that the bond, as given, fell within the scope of section 42 of the *Customs Act*, which empowers the Customs to require securities for compliance with the Act and for the protection of the revenue. The bond was held to cover goods under the control of the Customs, irrespective of whether they were dutiable. Section 42 was interpreted as allowing the Collector, as an agent of the Executive, to relinquish control of goods in exchange for security in forms approved under section 43, and the Governor-General was authorised by section 270 to prescribe the specific form of security. The Court found that the conditions of the bond, including the requirement for the satisfaction of the Collector, were reasonably necessary to ensure compliance with the Act and protect the revenue, making the security effective. Section 48 was considered a valid law relating to Customs and not an improper exercise of judicial power.

The Court also held that the bond could be sued upon by the Commonwealth, as the obligee was sufficiently identified. Furthermore, the *Customs Regulations* were considered validly made under section 270 of the Act. The Court followed the decision in *Marine Board of Hobart v. The Commonwealth*.
