Portiliminium

Portiliminium, denotes the doctrine under which the territory, individuals and property, after having come in time of war under the authority of the enemy, return, either during the war or at its end, under sway of their original sovereign. Their mere possession in the course of war, does not suffice generally to transfer title or sovereignty as against the enemy owner or sovereign. The rights of the owner of sovereign are merely suspended rather than destroyed by temporary loss of possession and the legal state of things existing prior to the hostile occupation is re-established, Singhal's Jurisprudence, p. 259.
