Oregon Revised Statutes Procedure in Criminal Matters Generally § 137.466

(1) If the court has ordered the Oregon Health Authority to perform a competency assessment of the defendant under ORS 137.464 and the assessment has been completed, the court shall determine the issue of the defendant's mental capacity to engage in reasoned choices of legal strategies and options. If neither the state nor counsel for the defendant contests the finding of the report filed under ORS 137.464, the court may make the determination of the defendant's mental capacity to engage in reasoned choices of legal strategies and options on the basis of the report. If the finding is contested, the court shall hold a hearing on the issue. If the report is received in evidence at the hearing, the party contesting the finding has the right to summon and to cross-examine the psychiatrist or psychologist who submitted the report and to offer evidence on the issue. Either party may introduce other evidence regarding the defendant's mental capacity to engage in reasoned choices of legal strategies and options.

(2) If the court determines that, due to mental incapacity, the defendant cannot engage in reasoned choices of legal strategies and options, the court shall continue the appointment of counsel provided under ORS 137.463.

(3) No appeal may be taken from an order issued pursuant to this section.
