Plato, Laws 879a

συγγενῶν τοῦ δράσαντος μηδένα δικάζειν, μηδʼ ἐὰν γεγονὼς ᾖ τὸν χρόνον ὅσον ὁ νόμος εἴρηκεν. δοῦλος δʼ ἐάν τις ἐλεύθερον ὀργῇ τρώσῃ, παραδότω τὸν δοῦλον ὁ κεκτημένος τῷ τρωθέντι χρῆσθαι ὅτι ἂν ἐθέλῃ· ἐὰν δὲ μὴ παραδιδῷ, αὐτὸς τὴν βλάβην ἐξιάσθω. ἐὰν δὲ ἐκ συνθήκης αἰτιᾶται τοῦ δούλου καὶ τοῦ τρωθέντος μηχανὴν εἶναί τις τὸ γεγονός, ἀμφισβητησάτω· ἐὰν δὲ μὴ ἕλῃ, τριπλασίαν ἐκτεισάτω τὴν βλάβην, ἑλὼν δέ, ἀνδραποδισμοῦ ὑπόδικον ἐχέτω τὸν τεχνάζοντα

If a slave wound a free man in rage, his owner shall hand over the slave to the wounded man to be dealt with just as he pleases; and if he do not hand over the slave, he shall himself make good the damage to the full. And if any man alleges that the deed was a trick concocted by the slave in collusion with the wounded party, he shall dispute the case: if he fail to win it, he shall pay three times the damage, but if he win, he shall hold liable for kidnapping the man who contrived the trick in collusion with the slave.
