[IDEM libro uicensimo nono ad Sabinum. ] §13.6.10.prEum, qui rem commodatam accepit, si in eam rem usus est in quam accepit, nihil praestare, si eam in nulla parte culpa sua deteriorem fecit, uerum est: nam si culpa eius fecit deteriorem, tenebitur.
[THE SAME in the twenty-ninth book on Sabinus.] It is true that a person who has received a borrowed thing is liable for nothing, if he used it for the purpose for which he received it, provided he has not in any part made it worse by his own fault; for if he has made it worse by his fault, he will be held liable.
§13.6.10.1Si rem in spectori dedi, an similis sit ei cui commodata res est, quaeritur.
If I have given a thing to an inspector, the question is raised whether he is in a similar position to one to whom a thing has been borrowed.
et si quidem mea causa dedi, dum uolo pretium exquirere, dolum mihi tantum praestabit: si sui, et custodiam: et ideo furti habebit actionem.
And if indeed I gave it for my own sake, while I wish to ascertain the price, he will be liable to me only for willful intent; if for his own sake, also for custody, and therefore he will have the action for theft.
sed et si dum refertur periit, si quidem ego mandaueram per quem remitteret, periculum meum erit: si uero ipse cui uoluit commisit, aeque culpam mihi praestabit, si sui causa accepit,
But also if it perished while being returned, if indeed I had commissioned the person through whom he should send it back, the risk will be mine; but if he himself entrusted it to whom he pleased, he will equally be liable to me for fault, if he received it for his own sake.
