1. The evidence offered, in the first instance, to show that the plaintiffs’ title to the slaves was acquired from Judge by fraud, was very properly rejected, because as the case then stood, the defendant was not connected with Judge, and therefore could have no interest in disputing a matter which Judge alone was competent to contest. For any thing then, disclosed, Judge may have acquiesced in the fraud, or subsequently have ratified the contract.
2. But this became a very different question, as soon as it was offered to show that the defendant held the slaves as the agent of Judge, and detained them from the plaintiffs in consequence of instructions from him. We apprehend it is clear that the vendor may defeat the legal sufficiency of his own bill of sale, and show that the contract evidenced by it is void, by reason of fraud.— The case of Root v. French, [13 Wend. 370,] cited by the counsel for the plaintiff in error, is indeed, a direct decision of that very point, and many others could be added. As the vendor may thus contest the validity of a title made by himself, on the ground of fraud, there is no sufficient reason why his bailee, acting under *201his instructions, should not be permitted to do so likewise. To hold it to be otherwise, would be, in effect, to declare that the law is incapable of protecting the servant, acting under the authority of his master, to the same extent as the master himself would be protected.
The law is so clear upon the facts disclosed by the bill of exceptions, that we are almost forced to conclude that some mistake has intervened, by which a different question is presented from that intended. If this is so, it will probably be rectified when the case is again tried.
3. The remaining point is the precise one settled in the cases of Goodwin v. Lloyd, [8 Porter, 237,] and Brown v. Lipscomb, [9 Porter, 472.] In both these cases, it was held, that when personal property is converted, the interest of the former owner is changed into a mere chose in action; in the case last cited, we say, “ If the owner of a personal chattel is not in actual possession, but it is withheld by another, and the owner, ignorant of the fact, under such circumstances parts with his title, it is conceived the purchaser would succeed to his rights ; but if the owner is dispossessed by one, bona fide claiming title, and the fact of dispossession and bona fide claim is known to, or communicated to Mm, his title is changed into a chose in action, wMch cannot be transferred or conveyed to another.” The evidence before the jury may not have warranted the charge requested, but the court assumes the conversion to be within the knowledge of the parties, and informs the jury that under such a state of facts-the verdict ought to be for the plaintiffs; thus, in our judgment, running counter to the opinion just quoted.
For rejecting the evidence of fraud, after the connexion between the defendant and Judge was established, and for the erroneous eharge, the judgment must be reversed, and the cause remanded.
