Oregon Revised Statutes Elections § 260.355

If, after a plea of guilty by or verdict of guilty against a person nominated or elected to a public office in a criminal prosecution of the person for violation of an election law in regard to either the person's nomination or election, the court determines that the violation was deliberate and material, the court, in addition to any other punishment it may impose, shall deprive the person of the nomination or, if the person was elected to an office other than state Senator or state Representative, of the office. In making the determination the court, in its discretion, may hear evidence, by testimony in open court or, if authorized by the court, by deposition, at a specified time and upon notice to the parties as the court may direct.
