— There is no valid objection to the competency of James Frazier as a witness, for if the defendants agreed to answer for his default, it was a contract entered into voluntarily and without request. It cannot, therefore, form the ground-work of a suit; for it is well settled, that a voluntary payment or engagement to pay the debt of another, gives no right of action against the original debtor. But the exception to the subject-matter of his testimony stands on a different -footing. The witness was admitted to prove that the judgment rendered against him was obtained by fraud ; that there was nothing due when rendered. But so- far as respects the defendant, who agreed to pay it, it is conclusive. It is so against Frazier, and why it should not be so against McKinsey, who voluntarily makes himself privy to it, it is difficult to understand. Suppose a man becomes surety for stay of execution in a judgment obtained either by default or by verdict of a jury, can it be that it is permitted to the surety to go behind the
Judgment reversed, and a venire de novo awarded.
