In reviewing the judgment of any court under ORS 34.310 to 34.730, the Court of Appeals, on its own motion or on the motion of the defendant, may summarily affirm, without oral argument, the judgment after submission of the appellant's brief and without submission of the defendant's brief if the court finds that no substantial question of law is presented by the appeal. Notwithstanding ORS 2.570, the Chief Judge of the Court of Appeals may deny or, if the plaintiff does not oppose the motion, grant a defendant's motion for summary affirmation. A dismissal of appeal under this section constitutes a decision upon the merits of the appeal.
