[IULIANUS libro quinto decimo digestorum. ] §18.1.39.prSi debitor rem pigneratam a creditore redemerit, quasi suae rei emptor actione ex uendito non tenetur et omnia in integro sunt creditori.
[JULIANUS, in the fifteenth book of Digests.] If a debtor should buy back a pledged thing from the creditor, he is, as it were, a buyer of his own thing, and is not held by the action on sale, and all things remain intact for the creditor.
§18.1.39.1Uerisimile est eum, qui fructum oliuae pendentis uendidisset et stipulatus est decem pondo olei quod natum esset, pretium constituisse ex eo quod natum esset usque ad decem pondo olei: idcirco solis quinque collectis non amplius emptor petere potest quam quinque pondo olei, quae collecta essent, a plerisque responsum est.
It is probable that one who sold the fruit of a hanging olive and stipulated for ten pounds of the oil that should be produced, established the price from that which should be produced up to ten pounds of oil; therefore, if only five pounds were collected, the buyer cannot demand more than the five pounds of oil which were collected, as has been answered by most.
