The view that enemy territory occupied by His Majesty's forces in time of war does not, by the fact of occupation, come within His Majesty's sovereignty or become part of his dominions, seems to be quite beyond doubt. One or two additional authorities may be cited. In American Insurance Co. v. 356 Bales of Cotton [3] (to which Mr. Holmes referred me) Marshall C.J. said: - "The usage of the world is, if a nation be not entirely subdued, to consider the holding of conquered territory as a mere military occupation, until its fate shall be determined at the treaty of peace. If it be ceded by the treaty, the acquisition is confirmed, and the ceded territory becomes a part of the nation to which it is annexed". It could certainly not be suggested that in September 1914 Germany was entirely subdued! And, when the treaty of peace was made, German New Guinea was not, as we shall see, ceded to Great Britain. The legal problems which may arise out of belligerent occupation are many and various, but in 1941 we find McNair (Law Quarterly Review, vol. 57, at pp. 37, 39) regarding the following two propositions as commanding general agreement among British textwriters: - "(a) That birth in British territory under enemy occupation confers British nationality iure soli, unless the father is an alien enemy", and "(b) That birth in non-British territory, whether enemy, allied or neutral, under British occupation, would not confer British nationality iure soli ". A suggested theory of "temporary sovereignty" seems long since to have been rejected. Writing in 1917 Oppenheim (Law Quarterly Review, vol. 33, at p. 363 (n.)) reproached himself for having failed to point out "that the obedience owed to the occupant is imposed upon the inhabitants by his martial law only, and neither by international nor by their own municipal law". A little later (at p. 364) he says: - "As regards the kind of authority an occupant possesses, Hall and others correctly describe it as mere military authority. There is not an atom of sovereignty in the authority of the occupant, since it is now generally recognized that the sovereignty of the legitimate government, although it cannot be exercised, is in no way diminished by mere military occupation".
