[IDEM libro singulari quaestionum publice tractatarum. ] §46.7.21.prSi unus ex fideiussoribus ob rem non defensam conuentus sit, deinde postea res defendatur, alter fideiussorum ob rem iudicatam conueniri potest.
[THE SAME, Single Book on Questions Publicly Discussed.] If one of the sureties has been sued on account of an undefended case, and then afterwards the case is defended, the other of the sureties can be sued on account of the judgment.
et si reus promittendi duobus heredibus relictis decesserit, alter rem non defendat, alter defendat: is qui non defendat ob rem non defensam conueniri potest, ille qui defendat ob rem iudicatam, quoniam in unius eiusdemque persona non posse committi has duas clausulas creditur et nos dicimus semper praeualere rei iudicatae clausulam eamque solam committi.
And if the promisor dies leaving two heirs, and one does not defend the case while the other does defend it: the one who does not defend can be sued on account of the undefended case, and the one who defends, on account of the judgment, since it is believed that these two clauses cannot be forfeited in the person of one and the same individual, and we say that the clause of the judgment always prevails and that it alone is forfeited.
