[GAIUS libro primo ad edictum prouinciale. ] §44.1.3.prExceptiones aut perpetuae et peremptoriae sunt aut temporales et dilatoriae.
[GAIUS in the first book on the provincial Edict.] Exceptions are either perpetual and peremptory, or temporary and dilatory.
perpetuae atque peremptoriae sunt, quae semper locum habent nec euitari possunt, qualis est doli mali et rei iudicatae et si quid contra legem senatusue consultum factum esse dicetur, item pacti conuenti perpetui, id est ne omnino pecunia petatur.
Perpetual and peremptory are those which always have place and cannot be avoided, such as the exception of fraud, of res judicata, and if it is alleged that something has been done contrary to a law or a senate decree, likewise of a perpetual agreement, that is, that the money should not be demanded at all.
temporales atque dilatoriae sunt, quae non semper locum habent, sed euitari possunt, qualis est pacti conuenti temporalis, id est ne forte intra quinquennium ageretur: procuratoriae quoque exceptiones dilatoriae sunt, quae euitari possunt.
Temporary and dilatory are those which do not always have place, but can be avoided, such as that of a temporary agreement, that is, lest by chance an action be brought within five years; procuratorial exceptions are also dilatory, which can be avoided.
