But the defence’ attempted in this case, does not make out a failure of title. The patent may have been issued to Nock-aetubba, and yet no covenant of Yancey be broken: Nock-ae-tubba may have conveyed to Yancey, with covenants of warranty, in which event, the former would be estopped by his deed, from disputing the title of the latter.
The reason of this rule is founded in the obvious policy, of not permitting, one, at pleasure, to disavow a title which he has admitted, by receiving a conveyance founded upon it; and beeause a court of law, cannot place the parties in the condition they were in, when the conveyance was executed.
Let the judgment be affirmed.
