[IDEM libro quarto decimo ad Plautium. ] §19.1.37.prSicut aequum est bonae fidei emptori alterius dolum non nocere, ita non est aequum eidem personae uenditoris sui dolum prodesse.
[The same, On Plautius, Book XIV.] Just as it is fair for a buyer in good faith that the fraud of another should not harm him, so it is not fair for the same person that the fraud of his own seller should benefit [the seller].
