It is clear that the allegations whose effect I have briefly stated in pars. (a) and (b) above could not form the basis of any cause of action. The annexation of the east coast of Australia by Captain Cook in 1770, and the subsequent acts by which the whole of the Australian continent became part of the dominions of the Crown, were acts of state whose validity cannot be challenged: see New South Wales v The Commonwealth (1975), 135 C.L.R. 337, at p. 388, and cases there cited. If the amended statement of claim intends to suggest either that the legal foundation of the Commonwealth is insecure, or that the powers of the Parliament are more limited than is provided in the Constitution, or that there is an aboriginal nation which has sovereignty over Australia, it cannot be supported. In fact, we were told in argument, it is intended to claim that there is an aboriginal nation which has sovereignty over its own people, notwithstanding that they remain citizens of the Commonwealth; in other words, it is sought to treat the aboriginal people of Australia as a domestic dependent nation, to use the expression which Marshall C.J. applied to the Cherokee Nation of Indians: Cherokee Nation v State of Georgia (1831), 5 Pet. 1, at p. 17. However, the history of the relationships between the white settlers and the aboriginal peoples has not be the same in Australia and in the United States, and it is not possible to say, as was said by Marshall C.J., at p. 16, of the Cherokee Nation, that the aboriginal people of Australia are organized as a "distinct political society separated from others", or that they have been uniformly treated as a state. The judgments in that case therefore provide no assistance in determining the position in Australia. The aboriginal people are subject to the laws of the Commonwealth and of the States or Territories in which they respectively reside. They have no legislative, executive or judicial organs by which sovereignty might be exercised. If such organs existed, they would have no powers, except such as the laws of the Commonwealth, or of a State or Territory, might confer upon them. The contention that there is in Australia an aboriginal nation exercising sovereignty, even of a limited kind, is quite impossible in law to maintain.
