[GAIUS libro tertio ad edictum prouinciale. ] §17.1.41.prPotest et ab una dumtaxat parte mandati iudicium dari: nam si is qui mandatum suscepit egressus fuerit mandatum, ipsi quidem mandati iudicium non competit, at ei qui mandauerit aduersus eum competit.
[GAIUS, On the Provincial Edict, Book III.] An action on mandate can also be given from only one party; for if he who undertook the mandate has exceeded the mandate, the action on mandate does not indeed lie for him himself, but it does lie for him who gave the mandate against him.
