In Australia, section 51(xxxi) of the Australian Constitution permits the Commonwealth Parliament to make laws with respect to "the acquisition of property on just terms from any State or person for any purpose in respect of which the Parliament has power to make laws." This has been construed as meaning that just compensation may not always include monetary or proprietary recompense, rather it is for the court to determine what is just. It may be necessary to imply a need for compensation in the interests of justice, lest the law be invalidated.
