Conception of State Servitudes.
§ 203. State servitudes are those exceptional and conventional restrictions on the territorial supremacy of a State by which a part or the whole of its territory is in a limited way made perpetually to serve a certain purpose or interest of another State. Thus a State may by a convention be obliged to allow the passage of troops of a neighbouring State, or may in the interest of a neighbouring State be prevented from fortifying a certain town near the frontier.
Servitudes must not be confounded[380] with those general restrictions upon territorial supremacy which, according to certain rules of the Law of Nations, concern all States alike. These restrictions are named "natural" restrictions of territorial supremacy (servitutes juris gentium naturales), in contradistinction to the conventional restrictions (servitutes juris gentium voluntariae) which constitute the State servitudes in the technical sense of the term. Thus, for instance, it is not a State servitude, but a "natural" restriction on territorial supremacy, that a State is obliged to admit the free passage of foreign merchantmen through its territorial maritime belt.
[380] This is done, for instance, by Heffter (§ 43), Martens (§ 94), Nys (II. p. 271), and Hall (§ 42*); the latter speaks of the right of innocent use of territorial seas as a servitude.
That State servitudes are or may on occasions be of great importance, there can be no doubt whatever. The vast majority[381] of writers and the practice of the States accept, therefore, the conception of State servitudes, although they do not agree with regard to the definition and the width of the conception, and although, consequently, in many cases the question is disputed whether a certain restriction upon territorial supremacy is or is not a State servitude.
[381] The conception of State servitudes is rejected by Bulmerincq (§ 49), Gareis (§ 71), Liszt (§§ 8 and 19), Jellinek ("Allgemeine Staatslehre," p. 366).
The theory of State servitudes has of late been rejected by the Permanent Court of Arbitration at the Hague in the case[382] (1910) of the North Atlantic Coast Fisheries between Great Britain and the United States, chiefly for the three reasons that a servitude in International Law predicated an express grant of a sovereign right, that the doctrine of international servitude originated in the peculiar and now obsolete conditions prevailing in the Holy Roman Empire, and that this doctrine, being little suited to the principle of sovereignty which prevails in States under a constitutional government and to the present international relations of Sovereign States, had found little, if any, support from modern publicists. It is hardly to be expected that this opinion of the Court will induce theory and practice to drop the conception of State servitudes, which is of great value because it fitly covers those restrictions on the territorial supremacy of the State by which a part or the whole of its territory is in a limited way made perpetually to serve a certain purpose or interest of another State. That the doctrine of State servitudes originated in the peculiar conditions of the Holy Roman Empire does not make it unfit for the conditions of modern life if its practical value can be demonstrated. Further, the assertion that the doctrine is but little suited to the principle of sovereignty which prevails in States under a constitutional government, and has, therefore, found little, if any, support from modern publicists, does not agree with the facts. Lastly, the statement that a servitude in International Law predicated an express grant of a sovereign right, is not based on any other authority than the contention of the United States, which made this unfounded statement in presenting their case before the Tribunal. The fact is that a State servitude, although to a certain degree it restricts the sovereignty (territorial supremacy) of the State concerned, does as little as any other restriction upon the sovereignty of a State confer a sovereign right upon the State in favour of which it is established.
