[POMPONIUS libro trigesimo primo ad Quintum Mucium. ] §18.1.12.prIn huiusmodi autem quaestionibus personae ementium et uendentium spectari debent, non eorum, quibus adquiritur ex eo contractu actio: nam si seruus meus uel filius qui in mea potestate est me praesente suo nomine emat, non est quaerendum, quid ego existimem, sed quid ille qui contrahit.
[POMPONIUS, in the thirty-first book on Quintus Mucius.] In questions of this kind, however, the persons of the buyers and sellers must be regarded, and not of those for whom an action is acquired from that contract; for if my slave, or a son who is in my power, should buy in his own name in my presence, we must not ask what I thought, but what he thought who contracted.
