[GAIUS libro trigensimo ad edictum prouinciale. ] §12.2.31.prAdmonendi sumus interdum etiam post iusiurandum exactum permitti constitutionibus principum ex integro causam agere, si quis noua instrumenta se inuenisse dicat, quibus nunc solis usurus sit.
[GAIUS, Book XXX on the Provincial Edict.] We must be reminded that sometimes, even after an oath has been exacted, it is permitted by imperial constitutions to try the case anew, if anyone should say that he has found new documents, which alone he will now use.
sed hae constitutiones tunc uidentur locum habere, cum a iudice aliquis absolutus fuerit (solent enim saepe iudices in dubiis causis exacto iureiurando secundum eum iudicare qui iurauerit): quod si alias inter ipsos iureiurando transactum sit negotium, non conceditur eandem causam retractare.
But these constitutions seem to apply only when someone has been acquitted by a judge (for in doubtful cases judges are often accustomed, after an oath has been exacted, to judge in favor of the person who has sworn); but if, on the other hand, the transaction was settled between the parties themselves by an oath, it is not permitted to reopen the same case.
