Debt by Spencer, assignee of Harris, against Barnett and Hanna. The declaration states that the defendants James Barnett and Samuel Hanna, (the plaintiffs in error,) on, &c., claimed an undivided moiety of a certain tract of land, which they had purchased of one Taylor, who had a claim of title to it under the pre-emption laws of the United States; that they and Taylor were in possession of the land as tenants in common; that one Gibo before, and at the same time, also claimed the-same land by virtue of title in him under the same laws, having a superior and better title than Taylor; that Gibo, for and in consideration that one Harris had undertaken to use his influence to have his title to the land confirmed, on, &c., executed his power of attorney to Harris, authorising and empowering him to act as the agent and attorney of Gibo to obtain a confirmation of his title,—which power of attorney was lost; that at the same time the power of attorney was executed, Gibo also made his obligation to Harris and bound himself in the penalty of 5,000 dollars to convey to Harris a moiety of one-third of the land, provided the title to the same should be decided to be in Gibo,—which obligation was also lost; that afterwards, on, &c., the defendants, in consideration of the agreement of Harris to prosecute the claim of Gibo to the land no further, executed to him their writing obliga*207tory, and thereby promised to pay him 400 dollars in three months, for value received; that afterwards, on, &c., the fendants paid Harris 155 dollars and one cent, which was credited on the writing obligatory; and that afterwards Harris, by endorsement on the uniting obligatory by him subscribed, assigned the sum of 244 dollars and 99 cents, it being the amount unpaid, to the plaintiff; whereby an action, &c.; concluding in proper form. The defendant demurred generally. Judgment for the plaintiff.

An objection is made to the legality of the assignment of the cause of action by Harris to the plaintiff, on the ground that only a part of the contract is attempted to be assigned. This objection is not well taken. The assignment is of the whole sum due on the contract, and is in effect a transfer of the contract itself. Harris parted with all his interest in it.

The demurrer, however, should have been sustained. The declaration shows that the consideration of the contract on which it is founded,-is deeply tinctured with fraud, at least on the part of Harris, the payee of the note. He had for a good consideration, and being clothed with full power, from Gibo, undertaken to lend his aid in procuring the confirmation of the title of the .latter to a certain tract of land, of which the plaintiffs in error and their co-tenant Taylor under a claim of title held possession. But upon his agreement to prosecute Gibo’s claim no further, he received from the plaintiffs in error their note for 400 dollars, which he assigned to Spencer the defendant in error. In attempting to enforce the payment of this demand, Spencer can stand in no better situation than his assignor.

“It is extremely difficult to advance any general principle or elementary doctrine upon the subject of fraud,” so various are the forms which it assumes. But it may safely be said that no claim founded in bad faith, in moral turpitude, in deception upon the public, or a third person, or in fraud practiced by one contracting party on the other, can constitute a good cause of action; and that rvhenever such a claim makes its appearance in a Court of justice, the law, ever watchful of public morals and private right, is sure to defeat the dishonest scheme, either by exerting its power or withholding its aid.

The objection to the validity of the contract under consideration is, that it was the price of the treachery of Harris to his *208Principal’ He had no right to contract to be unfaithful him. It is no answer to this view of the subject to say, that the withdrawal of Harris from the interest of Gibo, could not imPair the claim of the latter to the land. It deprived him of the services of his agent, and may well be supposed to have embarrassed and delayed him in the prosecution of his rights. Besides, where fraud is imputed, the question is not—whether-it has been successful, but whether it exists. Instances may be found in which contracts have been held to be void as being fraudulent upon third persons, when no injury was in fact done them. 3 Term Rep. 551.—4 Moore, 78. But admit that the conduct of Harris took nothing whatever from Gibo, of course, it could convey nothing to Barnett and Hanna; it would then follow, that instead of a fraudulent consideration, the contract had no consideration at all, and that it is void for that reason. We view it, however, in the former light, and hold that as a contract executed in consideration of the faithlessness of an agent to his principal, it is fraudulent and void.

The foregoing and following authorities clearly show that the cáse presented by the record, belongs to that class of contracts which have been decided to be invalid as frauds upon third persons. 1 Com. on Cont. 37, 38.—Chitt. on Cont. 214, 222 to 227.-2 Term Rep. 763.-4 id. 166.—4 B. & C. 319. 3 id. 605.—4 Esp. R. 179 (1).

The judgment is reversed with costs. Cause remanded, &c.
