[67] With this verdict he established the principle that¹ it was essential to good faith that any defect known to the vendor must be made known to the purchaser. If his decision was right, our grain-dealer and the vendor of the unsanitary house did not do right to suppress the facts in those cases. But the civil code cannot be made to include all cases where facts are thus suppressed; but those cases which it does include are summarily dealt with. Marcus Marius Gratidianus, a kinsman of ours, sold back to Gaius Sergius Orata the house which he himself had bought a few years before from that same Orata. It was subject to an encumbrance, but Marius had said nothing about this fact in stating the terms of sale. The case was carried to the courts. Crassus was counsel for Orata; Antonius was retained by Gratidianus. Crassus pleaded the letter of the law that “the vendor was bound to make good the defect, for he had not declared it, although he was aware of it”; Antonius laid stress upon the equity of the case, pleading that, “inasmuch as the defect in question had not been unknown to Sergius (for it was the [p. 339] same house that he had sold to Marius), no declaration of it was needed, and in purchasing it back he had not been imposed upon, for he knew to what legal liability his purchase was subject.”
