[PAPINIANUS libro sexto decimo quaestionum. ] §28.7.15.prFilius, qui fuit in potestate, sub condicione scriptus heres, quam senatus aut princeps improbant, testamentum infirmet patris, ac si condicio non esset in eius potestate: nam quae facta laedunt pietatem existimationem uerecundiam nostram et, ut generaliter dixerim, contra bonos mores fiunt, nec facere nos posse credendum est.
[PAPINIANUS, in the sixteenth book of Questions.] A son, who was under paternal power, when appointed heir under a condition which the senate or the emperor disapprove, may invalidate the testament of his father, just as if the condition were not within his power; for we must believe that we cannot perform those acts which offend our sense of duty, reputation, and modesty, and, to speak generally, are contrary to good morals.
