Australasian United Steam Navigation Co Ltd v The Shipping Control Board

The Australasian United Steam Navigation Co Ltd (the plaintiff) brought an action against the Shipping Control Board and the Commonwealth of Australia (the defendants) concerning the requisition of the plaintiff's steamship, the Macumba. The plaintiff alleged that the Commonwealth acquired property in the ship through the requisition and sought compensation for the ship's loss by enemy action, as well as for loss of profits and business disturbance. The defendants contended that the requisition was lawful and that the terms of compensation were governed by the National Security (Shipping Requisition) Regulations and a standard time charter party, which they argued provided just terms. The plaintiff demurred to parts of the defence, arguing that the relevant regulations and charter party provisions were invalid as they did not provide for just terms for the acquisition of property, as required by section 51(xxxi) of the Constitution.

The central legal issue before the High Court was whether the requisition of the steamship Macumba by the Commonwealth under the National Security (Shipping Control) Regulations constituted an acquisition of property within the meaning of section 51(xxxi) of the Constitution. This question hinged on whether the standard time charter party, which governed the terms of the requisition, resulted in the Commonwealth acquiring either property in or possession of the vessel. If an acquisition of property had occurred, the court would then need to determine if the terms of compensation provided by the regulations and charter party were "just terms" as mandated by the Constitution.

The Court held that the requisition of the ship did not amount to an acquisition of property by the Commonwealth. Applying the principles of charter parties, the Court found that under the standard time charter party, the owner retained control over the management, navigation, and handling of the ship. Consequently, neither property nor possession in the ship was acquired by the Commonwealth. As there was no acquisition of property, the constitutional requirement for compensation on "just terms" under section 51(xxxi) of the Constitution did not arise. The plaintiff's demurrer was therefore disallowed.
