In contrast with the writings of Welwood may be cited the opinions of another and more eminent Scottish lawyer, Sir Thomas Craig, who touched upon the subject of maritime jurisdiction in a non-controversial work published before the juridical controversy had arisen.[640] He states that the sea is common to all for navigation, but that property and jurisdiction in the adjacent sea pertains to the neighbouring territory according to the current opinion—the sea washing the coast of France, England, Scotland, Ireland, &c., to the respective countries. No limits or bounds are laid down by Craig as to the partitioning of the sea in this way, but when dealing with the theoretical question of islands arising in the sea, he follows Bartolus in assigning a space of 100 miles from the coast. He admits that certain seas may be prescribed, as the Adriatic, which Venice, though not possessing the shores, claimed by prescription. With respect to fisheries, the Scottish author, as might have been expected, holds that those in the adjoining sea belong to the bordering state: they are prescribed, and fishing there may be permitted or prohibited according to custom; and he says that it was not without great injury to us that the Dutch carry on their fishery around our islands.[641]

In the period that elapsed between the appearance of the works of Grotius and Welwood and the publication of Selden’s Mare Clausum, a number of other books were issued which dealt with the question of the freedom of the seas and the extent to which they might be appropriated. Gerard Malynes, in treatises on commerce which had a wide circulation, re-echoed the opinions of Welwood, and of Gentleman and Keymer. The “main great seas,” he said, were common to all nations for navigation and fishing, but the bordering sea was under the dominion of the prince of the adjoining country, and foreigners could only fish in it by obtaining permission and paying for the privilege; within this sea navigation was free unless it interfered with the fishings. Malynes said that this was the practice in Russia, Denmark, Sweden, and Italy; and he ascribed the decay of English fisheries and trade to the admission of foreigners to fish in “his Majesty’s streames” without paying for the liberty.[642] Two other authors, each celebrated in his respective sphere, touched upon the king’s dominion in the seas, and they may be regarded as representing two different aspects of the subject, both of which became of great importance—namely, the limits of neutral waters, and the rights of the crown by the Common Law of England to the propriety of the sea and its bed. One was Alberico Gentilis and the other Serjeant Callis.

Gentili, or Gentilis, who was a forerunner of Grotius in shaping the Law of Nations,[643] was an Italian of the school of Perugia, domiciled in England, where he held the Regius Professorship of Civil Law at Oxford. In 1605, after the conclusion of peace with Spain, he was appointed advocate for the Spanish embassy in London, and was frequently employed in the Admiralty Court in cases where the legality of the capture of Spanish vessels by the Dutch had to be determined. His pleadings and the decisions in these and similar cases were collected and published in 1613, after his death, and they form, according to Wheaton, the earliest reports of judicial decisions on maritime law published in Europe.[644]

In discharging his duties in the English Prize Courts, it often fell to the lot of Gentilis to deal with the jurisdiction of England in the seas, for while he held office war existed between Spain and the United Provinces, and Spanish ships were frequently taken by the Dutch in the neighbourhood of the British coasts. Of course, captures made in the King’s Chambers after the proclamation of 1604 ([see p. 119]) were not good prize, and were restored.[645] But when a Spanish vessel was seized clearly outside the limits of the King’s Chambers, Gentilis argued that it was not good prize, because, first, the treaty of peace[646] between Spain and England provided that the subjects of either were to be protected in all places throughout the dominions of the other; and, second, the dominion of the King of England extended far into the neighbouring seas. He seemed to stretch the joint sovereignty of Spain and England as far as America, pointing out that the southern coasts of Ireland were opposite to Spain, and the western coasts were bounded by the Indies belonging to Spain, while the northern coasts of Britain, having no countries lying against them, were washed by an immense and open sea. He held that the proclamation of 1604, fixing the limits of the chambers in connection with acts of hostilities between the Spaniards and the Hollanders, ought not to prevail against the provisions of the treaty, for the proclamation was subsequent to the treaty, and it would be unjust to allow it to lessen the extent of the territory (sea) over which protection was to be afforded by the terms of the contract. It was not a valid argument, Gentilis continued, to say that the boundaries expressed in the proclamation—that is, the King’s Chambers—had been observed long before by common usage in relation to similar cases.[647]

There is no doubt, however, that although Gentilis as an advocate took this line of pleading, the boundaries of the King’s Chambers from headland to headland, as defined by James in his “plat,” were received as settled law in regard to neutrality both in the English courts and on the Continent.[648] Gentilis further urged that the limit fixed by the Italian jurists for the extent of jurisdiction—viz., 100 miles from the coast, unless the proximity of another state interfered with its application—also was in force off the British coasts, a view which the court declined to accept.

Yet, although this principle of extending and limiting the territorial jurisdiction to 100 miles was not accepted in the English Courts, we find it made use of in the diplomatic correspondence of the time. The Earl of Salisbury in a letter to Cornwallis, the English ambassador at Madrid, explanatory of James’s proclamation in 1609 forbidding unlicensed fishing, did not seek to defend the action of the king by reason of any intrinsic right of the crown of England to sovereignty in the neighbouring sea, but rather upon what he alleged was the practice of the civil law. A sovereign prince or state, he said, was Mundi Dominus, Lex Maris, both because of the protection afforded to navigation in the adjacent sea and from prescription: the adjoining sea, as Baldus said, pertained to the territory of the neighbouring state, and thus the Venetians, as lords of the Adriatic, could impose taxes and penalties on navigation. “In respect of both which titles,” continued the Earl, “the Kings and Princes in general fronting upon the seas, as Spayne, France, Denmark, &c., have upon occasion offered, not only made ordinances and published edicts for the ruling and better ordering of the seas, but also have put them in execution; as well civilly for deciding of contracts, as criminally for transgressions; and have raised taxes and gabells in the seas as on the land to their best benefit, as part of their regalities properly belonging unto them, in sign of their sovereignty.” As to the distance to which this sovereignty extended, he said it was “generally received to be about one hundred miles at the least into the seas,” unless in narrow seas only, in which case the limits are divided by the channel, “except the princes of the one shore have prescribed the whole, as it falleth out in his Majesty’s narrow seas between England and France, where the whole appertayneth to him in right, and so hath been possessed tyme out of mind by his progenitors.”

By another channel we may trace the course of the ideas which converged and culminated in the claims of Charles to the dominion of the surrounding seas—viz., in connection with the development of the law relating to the rights of property in the foreshore and the bed of the sea. Cases frequently occurred in which those rights were contested between private individuals and the crown; and in the course of litigation, or in writings dealing with the subject, the rights in the sea which were alleged to belong to the crown were explained. We have already seen that Plowden, in a case of the kind, argued that Queen Elizabeth possessed jurisdiction as far as the middle line in the surrounding seas,—a doctrine which the queen expressly repudiated in 1602,—but denied to her any right of property in either the sea or its bed. The claims of the crown to the ownership of the foreshores originated in the reign of Elizabeth; under James and Charles I. they were systematically pursued by the “title-hunters”; and while the legal decisions in contested cases were for a long time adverse to the crown, they began in the reign of James to be in its favour, and gradually the idea was imported into and became a part of English law that the ownership of the foreshore was prima facie vested in the crown in virtue of the royal prerogative.[649]

Along with the development of this idea came another, which was ultimately likewise engrafted on English law—that the crown had the exclusive right of property in the sea and in the soil beneath it. The origin of the idea is to be found in a treatise written in 1569 by Thomas Digges.[650] He argued that as many things—as wrecks, treasure-trove, waifs and strays, which were originally common by the law of nature—now belonged to the Prince, so also should the sea, which was the chief of all waters, and could not by the civil law become the property of a subject. He held that just as the owners of the soil had the property in a river and its banks, the king had the interest and property in the “great salt river” environing the island, and in its shores and bottom; and he speaks of the sea as the “King’s river,” the “King’s streme,” and the “King’s water,” in which he had also jurisdiction. Digges also claimed that the fishings in the sea belonged to the crown, for “although the Kings of England have benne content to suffer fishermen Jure gentium to enjoy to theire owen use such fishe as by theire charges travill and adventure they can in the Englishe Seas take, Yet haue the Kings of England for remembrance of this theire favoure that the memorie of theire propertie in the Seas shoulde not be extinguished, alwaie reserved to them selves the cheif fishe as Sturgeon, Whale, &c.”[651]

The contention that the crown had the right of property in the sea and its bed, denied by Plowden, received in the reign of James much fuller amplification at the hands of Serjeant Callis, whose well-known lectures on the Statute of Sewers were delivered in 1622.[652] Callis argued that in “our Mare Anglicanum” the king had, by the common law of England, four “powers and properties”: sovereignty (imperium regale), legal jurisdiction for the administration of justice, property in the soil under the sea and in the water, and possession and profits both real and personal. He cites in proof a number of authorities, legal and historical, such as were cited later by Selden. The statement in a case decided in the reign of Richard II. (1377-99), that “the sea is within the legiance of the king as of his crown of England”; the charter of the Admiral giving him power in maritime cases throughout the realm of England; the phrases in certain statutes; the right to wreck and royal fishes, and so forth, “proved the King full Lord and owner of the seas, and that the seas be within the realm of England.” The king rules on the sea, he held, “by the laws imperial” as by the Roole d’Oleron and others, but only in the case of shipping and for merchants and mariners; his rights of property in the bed and waters of the sea, and the personal profits (wreck, flotsam, &c.) accruing, were his by the common law. Callis did not deal with fishing, nor attempt to define the bounds of “the seas of England” in which the king had property and jurisdiction.

The interpretation of the law as to the rights of the crown in the seas, as propounded by Callis, was followed by Selden and Hale, and generally by the lawyers who came after him. Lord Chief-Justice Coke, in his First Institute, which was published in 1628, explains the old phrase “within the four seas” (infra quatuor maria) as meaning within the kingdom and dominions of England; for if a man be upon the sea of England he is “within the kingdom or realm of England, and within the ligeance of the king of England, as of his crown of England.” In his Fourth Institute, which was not published, however, till 1644, ten years after his death, when treating of the Admiralty Court, Coke entered more fully into the question of the rights of the crown in the seas of England; and, as already mentioned, he looked upon the roll of Edward I., De Superioritate Maris, as proving that the king’s right of dominion over the sea had been expressly acknowledged by neighbouring nations.
