[270] It is impossible for a treatise to go into historical details, and to show the gradual disappearance of the old rule. But it is of importance to state the fact, that even during the nineteenth century—see, for instance, G. F. Martens, II. § 280; Twiss, II. § 64; Hall, § 139—it was asserted that in strict law all private enemy moveable property was as much booty as public property, although the growth of a usage was recognised which under certain conditions exempted it from appropriation. In the face of articles 46 and 47 of the Hague Regulations these assertions have no longer any basis, and all the text-books of the nineteenth century are now antiquated with regard to this matter.
Immoveable Public Property.
§ 134. Appropriation of public immoveables is not lawful so long as the territory on which they are has not become State property of the occupant through annexation. During mere military occupation of the enemy territory, a belligerent may not sell or otherwise alienate public enemy land and buildings, but only appropriate the produce of them. Article 55 of the Hague Regulations expressly enacts that a belligerent occupying enemy territory shall only be regarded as administrator and usufructuary of the public buildings, real property, forests, and agricultural works belonging to the hostile State and situated on the occupied territory; that he must protect the stock and plant, and that he must administer them according to the rules of usufruct. He may, therefore, sell the crop from public land, cut timber in the public forests and sell it, may let public land and buildings for the time of his occupation, and the like. He is, however, only usufructuary, and he is, therefore, prohibited from exercising his right in a wasteful or negligent way that would decrease the value of the stock and plant. Thus, for instance, he must not cut down a whole forest unless the necessities of war compel him.
Immoveable Property of Municipalities, and of Religious, Charitable, and the like Institutions.
§ 135. It must, however, be observed that the produce of such public immoveables only as belong to the State itself may be appropriated, but not the produce of those belonging to municipalities or of those which, although they belong to the hostile State, are permanently set aside for religious purposes, for the maintenance of charitable and educational institutions, and for the benefit of art and science. Article 56 of the Hague Regulations expressly enacts that such property is to be treated as private property.
Utilisation of Public Buildings.
§ 136. So far as the necessities of war demand, a belligerent may make use of public enemy buildings for all kinds of purposes. Troops must be housed, horses stabled, the sick and wounded nursed. Public buildings may in the first instance, therefore, be made use of for such purposes, although they may thereby be considerably damaged. And it matters not whether the buildings belong to the enemy State or to municipalities, whether they are regularly destined for ordinary governmental and municipal purposes, or for religious, educational, scientific, and the like purposes. Thus, churches may be converted into hospitals, schools into barracks, buildings used for scientific research into stables. But it must be observed that such utilisation of public buildings as damages them is justified only if it is necessary. A belligerent who turned a picture gallery into stables without being compelled thereto would certainly commit a violation of the Law of Nations.
Moveable Public Property.
§ 137. Moveable public enemy property may certainly be appropriated by a belligerent provided that it can directly or indirectly be useful for military operations. Article 53 of the Hague Regulations unmistakably enacts that a belligerent occupying hostile territory may take possession of the cash, funds, realisable securities, depôts of arms, means of transport, stores, supplies, appliances on land or at sea or in the air adapted for the transmission of news or for the transport of persons or goods, and of all other moveable property of the hostile State which may be used for military operations. Thus, a belligerent is entitled to seize not only the money and funds of the hostile State on the one hand, and, on the other, munitions of war, depôts of arms, stores and supplies, but also the rolling-stock of public railways[271] and other means of transport and everything and anything he can directly or indirectly make use of for military operations. He may, for instance, seize a quantity of cloth for the purpose of clothing his soldiers.
[271] See Nowacki, Die Eisenbahnen im Kriege (1906), §§ 15 and 19. Some writers—see, for instance, Bonfils, No. 1185, and Wehberg, op. cit. p. 22—maintain that such rolling stock may not be appropriated, but may only be made use of during war and must be restored after the conclusion of peace. The assertion that article 53, second paragraph, is to be interpreted in that sense, is unfounded, for restoration is there stipulated for such means of transport and the like as are private property.
