[PAPINIANUS libro uicensimo octauo quaestionum. ] §46.8.1.prCum quis de rato stipularetur: quamuis non idem, sed alius a domino conueniretur, qui conueniri non posset, si ratum habuisset, committi stipulationem placuit, ueluti si cum fideiussor aut alter ex reis promittendi, qui socius est, conuenitur.
[PAPINIANUS, Questions, Book XXVIII.] When someone has stipulated for ratification: although not the same person, but another is sued by the principal—one who could not have been sued if the principal had ratified—it has been held that the stipulation is forfeited, as for example if a surety or one of the co-promisors who is a partner is sued.
