Digestorum libri
Ex libro XI
Julianus, Digest, Book XI. Where a promisor agrees to deliver a slave and the slave dies when the former was to blame for his not having been delivered; even though he promised to deliver a slave, he will still be liable for a promise for the payment of money, and hence he must pay the value of the slave.
Julianus, Digest, Book XI. Where a creditor has received property in pledge and having lost possession of it proceeds by means of the Servian Action, and recovers damages; and the debtor afterwards brings suit for the same property, he will be barred by an exception, unless he offers him what was paid for it. 1Where a slave receives a pledge on account of his peculium, an action on pledge can be brought by the debtor against his master.
Julianus, Digest, Book XI. Therefore an Institorian equitable action can be brought by you against me; or, on the other hand, I can sue you either for the peculium of the slave who is managing the business, and also on the contract for hiring, if I desire to do so; or for the peculium of the sub-slave, because I gave him directions to sell the goods, and the price at which you made the purchase may be held as having reference to your affairs for the reason that you became a debtor to your own slave.
Julianus, Digest, Book XI. Because the proceeding is not based upon fraud, but includes the prosecution of a claim, and therefore, even if the slave is dead, the master, as well as his heir, should be held perpetually liable for the act of the deceased; although the action will not lie except where fraud has been committed.
Julianus, Digest, Book XI. Note by Marcellus. Sometimes, also, the action for property employed in the affairs of another can be brought against one joint-owner; for the reason that such employment of property has taken place, and he, having been sued, can recover from his partner the amount for which judgment has been rendered against him. What shall we say, however, if the slave has been deprived of the peculium by one of the owners? Paulus says that this question only arises where an action on the peculium does not lie.
