Oregon Revised Statutes Procedure in Criminal Matters Generally § 136.500

A motion in arrest of judgment is an application on the part of the defendant that no judgment be rendered on a plea or verdict of guilty. It may be founded on either or both of the grounds specified in ORS 135.630 (1) and (4), and not otherwise. The motion must be made within the time allowed to file a motion for a new trial, and both such motions may be made and heard as the court directs.
