8 Finally, it should be observed that where a contract has been entered into by a slave or son in power at his master's or parent's bidding, or where there has been a conversion to his uses, a condiction may be brought directly against the parent or master, exactly as if he had been the original contracting party in person. So too, wherever a man is suable by either of the actions called exercitoria and institoria, he may, in lieu thereof, be sued directly by a condiction, because in effect the contract in such cases is made at his bidding. TITLE VIII. OF NOXAL ACTIONS Where a delict, such as theft, robbery, unlawful damages, or outrage, is committed by a slave, a noxal action lies against the master, who on being condemned has the option of paying the damages awarded, or surrendering the slave in satisfaction of the injury. 1 The wrongdoer, that is, the slave, is called 'noxa'; 'noxia' is the term applied to the wrong itself, that is, the theft, damage, robbery, or outrage. 2 This principle of noxal surrender in lieu of paying damages awarded is based on most excellent reason, for it would be unjust that the misdeed of a slave should involve his master in any detriment beyond the loss of his body. 3 If a master is sued by a noxal action on the ground of his slave's delict, he is released from all liability by surrendering the slave in satisfaction of the wrong, and by this surrender his right of ownership is permanently transferred; though if the slave can procure enough money to compensate the surrenderee in full for the wrong he did him, he can, by applying to the praetor, get himself manumitted even against the will of his new master. 4 Noxal actions were introduced partly by statute, partly by the Edict of the praetor; for theft, by the statute of the Twelve Tables; for unlawful damages, by the lex Aquilia; for outrage and robbery, by the Edict. 5 Noxal actions always follow the person of the wrongdoer. Thus, if your slave does a wrong while in your power, an action lies against you; if he becomes the property of some other person, that other is the proper person to be sued; and if he is manumitted, he becomes directly and personally liable, and the noxal action is extinguished. Conversely, a direct action may change into noxal; thus, in an independent person has done a wrong, and then becomes your slave (as he may in several ways described in the first Book), a noxal action lies against you in lieu of the direct action which previously lay against the wrongdoer in person.
