[PAULUS libro decimo quaestionum. ] §45.3.12.prNam cum uterque obligationis capax sit, non inuenimus, quis adiectus sit, quia non est, qui petere possit.
[PAULUS, from the tenth book of Questions.] For since both are capable of holding an obligation, we do not find who was added, because there is no one who can sue.
