[PAULUS libro septuagesimo ad edictum. ] §44.2.14.pret an eadem causa petendi et eadem condicio personarum: quae nisi omnia concurrunt, alia res est.
[PAULUS, on the edict, book seventy.] and whether there is the same cause of action and the same status of the persons: unless all these concur, it is a different matter.
idem corpus in hac exceptione non utique omni pristina qualitate uel quantitate seruata, nulla adiectione deminutioneue facta, sed pinguius pro communi utilitate accipitur.
Under this exception, the same physical thing is understood not necessarily as preserving every former quality or quantity, with no addition or diminution made, but more broadly for the sake of common utility.
§44.2.14.1Qui, cum partem usus fructus haberet, totum petit, si postea partem adcrescentem petat, non summouetur exceptione, quia usus fructus non portioni, sed homini adcrescit.
A person who, when holding a part of a usufruct, claimed the whole, is not barred by the exception if he subsequently claims the accruing part, because a usufruct accrues not to the share, but to the person.
§44.2.14.2Actiones in personam ab actionibus in rem hoc differunt, quod, cum eadem res ab eodem mihi debeatur, singulas obligationes singulae causae sequuntur nec ulla earum alterius petitione uitiatur: at cum in rem ago non expressa causa, ex qua rem meam esse dico, omnes causae una petitione adprehenduntur.
Personal actions differ from real actions in this respect: when the same thing is owed to me by the same person, individual causes follow individual obligations, and none of them is vitiated by the petition of another; but when I bring a real action without expressing the cause from which I say the thing is mine, all causes are comprehended in a single petition.
neque enim amplius quam semel res mea esse potest, saepius autem deberi potest.
For a thing cannot be mine more than once, but it can be owed to me more than once.
§44.2.14.3Si quis interdicto egerit de possessione, postea in rem agens non repellitur per exceptionem, quoniam in interdicto possessio, in actione proprietas uertitur.
If anyone has sued by interdict concerning possession, and afterwards brings a real action, he is not repelled by the exception, since in the interdict, possession is at issue, but in the action, ownership.
