[GAIUS libro septimo ad edictum prouinciale. ] §6.2.13.prQuaecumque sunt iustae causae adquirendarum rerum, si ex his causis nacti res amiserimus, dabitur nobis earum rerum persequendarum gratia haec actio.
[GAIUS on the Provincial Edict, book 7] Whatever are the just causes for acquiring things, if we have lost the things after having obtained them based on these causes, this action shall be granted to us for the sake of pursuing those things.
§6.2.13.1Interdum quibusdam nec ex iustis possessionibus competit Publicianum iudicium: namque pigneraticiae et precariae possessiones iustae sunt, sed ex his non solet competere tale iudicium, illa scilicet ratione, quia neque creditor neque is qui precario rogauit eo animo nanciscitur possessionem, ut credat se dominum esse.
Sometimes, the Publician action is not available to certain persons even from just possessions; for pledge possessions and precarium possessions are just, but from these, such an action is not customarily available, obviously for this reason, because neither the creditor nor he who asked by precarium obtains possession with that mind, that he believes himself to be the owner.
§6.2.13.2Qui a pupillo emit, probare debet tutore auctore lege non prohibente se emisse.
He who buys from a ward must prove that he bought with the authorization of the tutor and without the law prohibiting it.
sed et si deceptus falso tutore auctore emerit, bona fide emisse uidetur.
But even if, deceived, he bought with the authorization of a false tutor, he is deemed to have bought in good faith.
