The maritime sovereignty claimed by Selden for the kings of England was of the most absolute kind. Speaking particularly of the eastern and southern parts of the English sea, lying between England and the shores of France and Germany,--in which Charles was especially interested,--he declared that the powers exercised by the kings of England from the time of the Norman Conquest were as follows: (1) the custody, government, and admiralty, as if it were a territory or province of the king; (2) leave of passage granted to foreigners at their request; (3) liberty of fishing in them conceded to foreigners, and protection afforded to their fishermen; (4) the prescribing of laws and limits to foreigners in hostility with one another as to the taking of prizes.[670] It is to be noted that Selden in expounding his case expressly rejected the principle of the mid-line, the limits laid down by the Italian writers, and those prescribed by King James in defining the King’s Chambers; and he disclaimed the arguments used by the English commissioners at the Bremen Conference in 1602, as to the freedom of the seas, as being contrary to English rights. He concludes his famous book in the following words: “It is certainly true, according to the mass of evidence set forth above, that the very shores or ports of the neighbouring sovereigns on the other side of the sea are the bounds of the maritime dominion of Britain, to the southwards and eastwards; but in the open and vast ocean to the north and west they are to be placed at the farthest extent of the most spacious seas which are possessed by the English, Scots, and Irish.” It may be added that _Mare Clausum_ became in a sense a law-book, an authoritative work to which eminent lawyers, as Lord Chief-Justice Hale and Hargrave, appealed as proving the existence and the legality of the rights of the crown of England to the dominion of the British seas. Even as late as the year 1830 this doctrine held its place in certain recognised treatises on the law of England, together with Selden’s definition of the extent of those seas. (See p. 580.)
