"Requisition" is not a technical legal term. The word is used to include the taking of property in full ownership, the taking of the possession of property, and the acquisition of a right to use property in a particular manner without any taking of possession. In The Meandros (1), a ship was requisitioned and it was held that the terms of requisition in that case did not deprive the defendants of their property in the vessel, but it was said (2)- A requisition is a process by which the State takes the use or the possession of, or the property in, chattels, and sometimes in land. But it is infinitely various "and examples are given (3): Cf. Swift v. Macbean (4), and The Steaua Romana; The Oltenia (5) Requisitioning may be, and usually is, nothing more than a hiring of the ship which does not take the property in the ship out of the owner." The same opinion was expressed in The Broadmayne (6). Accordingly the requisitioning of a ship may or may not involve the taking of property in the ship, according to the actual terms of the requisition.
It has been decided by this Court that the taking of possession of property is an acquisition of property within the meaning of S. 51 (xxxi.) of the Constitution (Minister of State for the Army v. Dalziel (7). The first question for determination in the present case is whether, by the requisitioning of the, the Commonwealth, though it did not become the registered owner of the ship, acquired property in the ship by taking possession.
All charterers of ships, by virtue of the charter party, have some control over the ship. Such control may relate only to a particular voyage; it may operate during a specified period. If the charter party is by way of demise, property in the ship temporarily passes to the charterer--for the duration of the charter. If possession, as well as some degree of control, passes to the charterer, then the property passes to the charterer and he is pro tempore the owner. But no property in the ship passes if possession is not given to the charterer by virtue of the terms of the charter. If the control of master and crew in the navigation of the ship passes to the charterer he has possession. If, on the other hand, he acquires only a right to the use of the ship-a right to use her carrying capacity (Carver, Carriage by Sea, 8th ed. (1938), p. 244, par. 153) there is no demise, but only a contract for services-location operis vehendarum mercium (Schuster v. McKellar (8); Burnard v. Aaron and Sharpley (9) ). Thus the general test is "whose servants the master and crew were"
