Gaius, On the Provincial Edict, Book XXX. We must remember that sometimes, even after the oath has been exacted, it is permitted by the Imperial Constitutions to have recourse to ordinary proceedings, where the party interested alleges that new documents have been found which he now only desires to use. These Constitutions are held to be available solely where a party has been discharged by the court; for judges, after requiring an oath, are frequently accustomed to render a decision in favor of the party who was sworn; but where the matter has been settled between the parties by means of an oath, it is not permitted for the same case to be reheard.
Gaius, On the Provincial Edict, Book XXX. Where a suit involving an estate is pending between you and myself, and you have in your possession some property belonging to said estate, and I also have some, there is nothing to prevent me from bringing an action against you to recover the estate, and, on the other hand, nothing to prevent you from bringing an action against me for the same purpose. If, however, after the case has been disposed of, you bring such an action against me, it will be necessary to ascertain whether the estate was adjudged to be mine or yours. If it was decided to be mine, the exception on the ground of res judicata will operate as a bar against you; because, for the very reason that judgment has been rendered in my favor, and the estate found to belong to me, it has been decided not to be yours. If, however, it has been found not to belong to me, nothing is understood to have been determined with reference to your title to it, because it may be that the estate does not belong to either of us.
Gaius, On the Provincial Edict, Book XXX. If I bring suit against you to recover property which belongs to me, and you are discharged from all liability because you proved that you have ceased to hold possession of said property, without any fraud on your part; and then, after you have obtained possession of said property a second time, I again bring an action against you, an exception on the ground of res judicata cannot effectually be interposed against me.

If, through the agency of a creditor, his debtor should happen to lose the money which he was about to pay him, the creditor will be barred by an exception on the ground of fraud. The same rule will apply when the creditor does not ratify the payment of money by his debtor to his own creditor.
