Book IIIChapter XVI: On Moderation with Respect to Things Excluded from the Right of Postliminium by the Law of Nations
I. H
But things, taken in unjust war, are to be restored, not only by those, who have taken them, but by others also into whose hands they may have by any means fallen. For, as the Roman lawyers say, no one can convey to another a greater right than he himself possesses. The original captor had no just title to any property therein, neither can the person, deriving his title through him, establish any better claim.—A
II. and III. Therefore such things are to be restored to those, from whom they were taken, which we find in ancient times was often done. Livy in relating the defeat of the Volscians and Aequi by a Roman Consul, says that the booty was exposed in a public place, for the space of three days, that every one, coming to recognise what belonged to him, might take it away.
But if any one has become possessed of such a thing by purchase, it may be asked, if he can charge the person from whom it was originally taken, with the price which he has paid for it? According to the principles before laid down, he certainly may charge as much to the person losing it, as the repossession of a thing, which he despaired of ever recovering, is worth.
The history of Abraham seems applicable to this subject, when he returned from his victory over the five kings. Being a man of noble and exalted piety, he would appropriate nothing to himself, but considering the things retaken, as his own right, in recompence for his labour and danger, he devoted a tenth part to God, after deducting the necessary expences, and divided a certain portion among his companions.

V. The period also, when the obligation to restitution expires, is often a subject of inquiry. But this is a question, when arising between subjects of the same kingdom, which must be settled by the municipal laws of that country: but when the contending parties are the subjects of foreign powers, the matter can only be decided upon a conjecture of the time sufficient to constitute a presumed dereliction of property.
VI. But where the right of war is doubtful, it will be safest to follow the conduct of Aratus of Sicyon, in advising the new possessors in some measure to prefer taking a sum of money in lieu of the possession, and recommending the same maxim to the original owners, to prefer a sum of money, if they could obtain it, equivalent to the recovery of their right.
