[GAIUS libro secundo ad edictum praetoris urbani titulo de liberali causa. ] §40.16.1.prNe quorundam dominorum erga seruos nimia indulgentia inquinaret amplissimum ordinem eo, quod paterentur seruos suos in ingenuitatem proclamare liberosque iudicari, senatus consultum factum est Domitiani temporibus, quo cautum est, ut, si quis probasset per collusionem quicquam factum, si iste homo seruus sit, fieret eius seruus qui detexisset collusionem.
[GAIUS, in the second book on the Edict of the Urban Praetor, under the title "On Liberty Suits".] Lest the excessive indulgence of certain masters toward their slaves should defile the most distinguished order by the fact that they permitted their slaves to claim freeborn status and to be judged free, a senate decree was passed in the times of Domitian, in which it was provided that, if anyone should prove that anything was done through collusion, if that man indeed be a slave, he should become the slave of him who had detected the collusion.
