However, I do not think that the decision in this case really depends on these topics of newly-discovered importance. It is not that I do not appreciate that there is a relationship between questions of the title to the bed of the ocean and the right to fish in ocean waters. There is, and it has long been noticed by English law. It was strikingly stated by Hale in Ch. IV of De Jure Maris: but Hale wrote when the King claimed a right over the whole of the narrow sea. "In this sea", he said, "the King of England hath a double right, viz. a right of jurisdiction which he ordinarily exerciseth by his admiral, and a right of propriety or ownership." That claim has been long since abandoned. It had indeed been discarded from the common law long before the decision in Reg v Keyn [2] . Now, notwithstanding the obvious physical relationship, and the generally assumed legal relationship, between ocean waters and the earth beneath them, I think that what are Australian waters for the purposes of the Commonwealth power over fisheries can be decided without any final pronouncement concerning proprietary rights and interests in any part of the bed of the ocean, whether the continental shelf or some narrower belt from the land. Moreover the present case must be decided by the law of Australia, not by recourse to doctrines of international law, except so far as they have been taken into and become part of the law of the land. Looking at the case in the way that I think a common lawyer should, and resisting the temptation to decide where doctors disagree, I doubt whether anything is to be gained by preferring one to the other of the several juristic analyses which have been offered of the nature of a nation's rights in the territorial sea. These may be found conveniently set out and usefully considered by Professor O'Connell in his International Law (1965), vol. 1, pp. 533-542. But the topic cannot be put completely aside in considering what is meant by the words "Australian waters beyond territorial limits". The concept of national sovereignty, as understood in international law, may seem an intruder into what is ultimately a question of statutory interpretation, of the meaning of words in the Constitution. But there are, in my view, several reasons why it cannot be altogether overlooked. One is that s. 51 (x.) of the Constitution is a provision of an Imperial statute, enacted in 1900, demarking Commonwealth legislative powers from those of the States. It must be read vis-à-vis an examination of the jurisdiction of the States in respect of the sea. Professor O'Connell brought to light some complexities in the learned article, "Problems of Australian Coastal Jurisdiction", he contributed to the 1958 British Year Book of International Law. In substance, and brought up to a later date, it is now to be found as Ch. XI of the book International Law in Australia. I acknowledge my indebtedness to this article, adding that I have studied too the criticisms of it, and comments on the same topic, which have appeared in several Australian university law reviews. I shall state later my own conclusions on the legal provinces of the Commonwealth and the States in relation to the open sea and fisheries there, so far as that is relevant in this case. At this point I say only that I do not think that the area of Commonwealth power with respect to fisheries under the Constitution is to be determined by seeking to define the bounds of "Australian waters" independently of the context "fisheries".
