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.

6 But no action lies for an offence committed by a slave against his master, for between a master and a slave in his power there can be no obligation; consequently, if the slave becomes the property of some other person, or is manumitted, neither he nor his new master can be sued; and on the same principle, if another man's slave commits a wrong against you, and then becomes your property, the action is extinguished, because it has come into a condition in which an action cannot exist; the result being that even if the slave passes again out of your power you cannot sue. Similarly, if a master commits a wrong against his slave, the latter cannot sue him after manumission or alienation.

7 These rules were applied by the ancients to wrongs committed by children in power no less than by slaves; but the feeling of modern times has rightly rebelled against such inhumanity, and noxal surrender of children under power has quite gone out of use. Who could endure in this way to give up a son, still more a daughter, to another, whereby the father would be exposed to greater anguish in the person of a son than even the latter himself, while mere decency forbids such treatment in the case of a daughter? Accordingly, such noxal actions are permitted only where the wrongdoer is a slave, and indeed we find it often laid down by old legal writers that sons in power may be sued personally for their own delicts.
