Section 138.550 - Availability of relief as affected by prior judicial proceedings The effect of prior judicial proceedings concerning the conviction of petitioner which is challenged in the petition shall be as specified in this section and not otherwise:
(1) The failure of petitioner to have sought appellate review of the conviction, or to have raised matters alleged in the petition at the trial of the petitioner, shall not affect the availability of relief under ORS 138.510 to 138.680. But no proceeding under ORS 138.510 to 138.680 shall be pursued while direct appellate review of the conviction of the petitioner, a motion for new trial, or a motion in arrest of judgment remains available.(2) When the petitioner sought and obtained direct appellate review of the conviction and sentence of the petitioner, no ground for relief may be asserted by petitioner in a petition for relief under ORS 138.510 to 138.680 unless such ground was not asserted and could not reasonably have been asserted in the direct appellate review proceeding. If petitioner was not represented by counsel in the direct appellate review proceeding, due to lack of funds to retain such counsel and the failure of the court to appoint counsel for that proceeding, any ground for relief under ORS 138.510 to 138.680 which was not specifically decided by the appellate court may be asserted in the first petition for relief under ORS 138.510 to 138.680, unless otherwise provided in this section.(3) All grounds for relief claimed by petitioner in a petition pursuant to ORS 138.510 to 138.680 must be asserted in the original or amended petition, and any grounds not so asserted are deemed waived unless the court on hearing a subsequent petition finds grounds for relief asserted therein which could not reasonably have been raised in the original or amended petition. However, any prior petition or amended petition which was withdrawn prior to the entry of judgment by leave of the court, as provided in ORS 138.610, shall have no effect on petitioner's right to bring a subsequent petition.(4) Except as otherwise provided in this subsection, no ground for relief under ORS 138.510 to 138.680 claimed by petitioner may be asserted when such ground has been asserted in any post-conviction proceeding prior to May 26, 1959, and relief was denied by the court, or when such ground could reasonably have been asserted in the prior proceeding. However, if petitioner was not represented by counsel in such prior proceeding, any ground for relief under ORS 138.510 to 138.680 which was not specifically decided in the prior proceedings may be raised in the first petition for relief pursuant to ORS 138.510 to 138.680. Petitioner's assertion, in a post-conviction proceeding prior to May 26, 1959, of a ground for relief under ORS 138.510 to 138.680, and the decision of the court in such proceeding adverse to the petitioner, shall not prevent the assertion of the same ground in the first petition pursuant to ORS 138.510 to 138.680 if the prior adverse decision was on the ground that no remedy heretofore existing allowed relief upon the grounds alleged, or if the decision rested upon the inability of the petitioner to allege and prove matters contradicting the record of the trial which resulted in the conviction and sentence of the petitioner.
