[IDEM libro decimo disputationum. ] §50.17.60.prSemper qui non prohibet pro se interuenire, mandare creditur.
[THE SAME, in the tenth book of his Disputations.] He who does not forbid someone to intervene on his behalf is always deemed to have given a mandate.
sed et si quis ratum habuerit quod gestum est, obstringitur mandati actione.
But also, if anyone ratifies what has been done, he is bound by the action of mandate.
