(4) The littoral State can make laws and regulations regarding maritime ceremonials to be observed by such foreign merchantmen as enter its territorial maritime belt.[339]

Navigation within the Belt.

§ 188. Although the maritime belt is a portion of the territory of the littoral State and therefore under the absolute territorial supremacy of such State, the belt is nevertheless, according to the practice of all the States, open to merchantmen of all nations for inoffensive navigation, cabotage excepted. And it is the common conviction[340] that every State has by customary International Law the right to demand that in time of peace its merchantmen may inoffensively pass through the territorial maritime belt of every other State. Such right is correctly said to be a consequence of the freedom of the Open Sea, for without this right navigation on the Open Sea by vessels of all nations would in fact be an impossibility. And it is a consequence of this right that no State can levy tolls for the mere passage of foreign vessels through its maritime belt. Although the littoral State may spend a considerable amount of money for the erection and maintenance of lighthouses and other facilities for safe navigation within its maritime belt, it cannot make merely passing foreign vessels pay for such outlays. It is only when foreign ships cast anchor within the belt or enter a port that they can be made to pay dues and tolls by the littoral State. Some writers[341] maintain that all nations have the right of inoffensive passage for their merchantmen by usage only, and not by the customary Law of Nations, and that, consequently, in strict law a littoral State can prevent such passage. They are certainly mistaken. An attempt on the part of a littoral State to prevent free navigation through the maritime belt in time of peace would meet with stern opposition on the part of all other States.

But a right of foreign States for their men-of-war to pass unhindered through the maritime belt is not generally recognised. Although many writers assert the existence of such a right, many others emphatically deny it. As a rule, however, in practice no State actually opposes in time of peace the passage of foreign men-of-war and other public vessels through its maritime belt. And it may safely be stated, first, that a usage has grown up by which such passage, if in every way inoffensive and without danger, shall not be denied in time of peace; and, secondly, that it is now a customary rule of International Law that the right of passage through such parts of the maritime belt as form part of the highways for international traffic cannot be denied to foreign men-of-war.[342]

[342] See below, § [449].

Jurisdiction within the Belt.

§ 189. That the littoral State has exclusive jurisdiction within the belt as regards mere matters of police and control is universally recognised. Thus it can exclude foreign pilots, can make custom-house arrangements, sanitary regulations, laws concerning stranded vessels and goods, and the like. It is further agreed that foreign merchantmen casting anchor within the belt or entering a port,[343] fall at once and ipso facto under the jurisdiction of the littoral State. But it is a moot point whether such foreign vessels as do not stay but merely pass through the belt are for the time being under this jurisdiction. It is for this reason that the British Territorial Waters Jurisdiction Act of 1878 (41 & 42 Vict. c. 73), which claims such jurisdiction, has called forth protests from many writers.[344] The controversy itself can be decided only by the practice of the States. The British Act quoted, the basis of which is, in my opinion, sound and reasonable, is a powerful factor in initiating such a practice; but as yet no common practice of the States can be said to exist.
