Oregon Revised Statutes Procedure in Criminal Matters Generally § 138.660

In reviewing the judgment of the circuit court in a proceeding pursuant to ORS 138.510 to 138.680, the Court of Appeals on its own motion or on motion of respondent may summarily affirm, after submission of the appellant's brief and without submission of the respondent's brief, the judgment on appeal without oral argument if it 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 petitioner does not oppose the motion, grant a respondent's motion for summary affirmation. A dismissal of the appeal under this section shall constitute a decision upon the merits of the appeal.
