Dereliction.
§ 247. Dereliction as a mode of losing corresponds to occupation as a mode of acquiring territory. Dereliction frees a territory from the sovereignty of the present owner State. Dereliction is effected through the owner State's complete abandonment of the territory with the intention of withdrawing from it for ever, thus relinquishing sovereignty over it. Just as occupation[476] requires, first, the actual taking into possession (corpus) of territory and, secondly, the intention (animus) to acquire sovereignty over it, so dereliction requires, first, actual abandonment of a territory, and, secondly, the intention to give up sovereignty over it. Actual abandonment alone does not involve dereliction as long as it must be presumed that the owner has the will and ability to retake possession of the territory. Thus, for instance, if the rising of natives forces a State to withdraw from a territory, such territory is not derelict as long as the former possessor is able and makes efforts to retake possession. It is only when a territory is really derelict that any State may acquire it through occupation.[477] History knows of several such cases. But very often, when such occupation of derelict territory occurs, the former owner protests and tries to prevent the new occupier from acquiring it. The cases of the island of Santa Lucia and of the Delagoa Bay may be quoted as illustrations:—
(a) In 1639 Santa Lucia, one of the Antilles Islands, was occupied by England, but in the following year the English settlers were massacred by the natives. No attempt was made by England to retake the island, and France, considering it no man's land, took possession of it in 1650. In 1664 an English force under Lord Willoughby attacked the French, drove them into the mountains, and held the island until 1667, when the English withdrew and the French returned from the mountains. No further step was made by England to retake the island, but she nevertheless asserted for many years to come that she had not abandoned it sine spe redeundi, and that, therefore, France in 1650 had no right to consider it no man's land. Finally, however, England resigned her claims by the Peace Treaty of Paris of 1763.[478]

(b) In 1823 England occupied, in consequence of a so-called cession from native chiefs, a piece of territory at Delagoa Bay, which Portugal claimed as part of the territory owned by her at the bay, maintaining that the chiefs concerned were rebels. The dispute was not settled until 1875, when the case was submitted to the arbitration of the President of France. The award was given in favour of Portugal, since the interruption of the Portuguese occupation in 1823 was not to be considered as abandonment of a territory over which Portugal had exercised sovereignty for nearly three hundred years.[479]
