Peirce v. Chase

By the Court. Proof that a witness has confessed himself interested in the event of a cause is not sufficient to disqualify him. But where it is proved that the party, by whom the witness is introduced, has acknowledged him so interested, the witness ought not to be sworn. As the deposition of Legate was therefore im properly admitted at the trial, the verdict in this case must be se aside, and a new trial granted.
