(2) If the trial court determines that the decision is not appealable, the trial court, in its discretion, may proceed through entry of judgment or stay proceedings pending an appellate court determination of the existence of an appealable decision. The trial court may refer the question of the existence of an appealable decision to the court to which the appeal is taken. Neither an order by the trial court to proceed through entry of judgment, an order by the trial court to stay proceedings pending an appellate court determination, nor a trial court referral of the question of the existence of an appealable decision to the appellate court is appealable. However, on motion of any party or on its own motion the appellate court may stay proceedings in the trial court or stay any order or judgment entered by the trial court pending a final determination of appealability.

(3) When a party by motion, the trial court by referral or the appellate court on its own motion raises the issue whether the decision is appealable, the appellate court may make a summary determination of the appealability of the decision. A summary determination of the appealability of a decision under this subsection is subject to review by the Supreme Court as provided in ORS 2.520 except that the petition for review shall be served and filed within 14 days after the date of the court’s determination. Either the Court of Appeals or the Supreme Court may shorten the time period within which the petition for review shall be filed. A petition for review of a determination under this subsection shall not be treated as a request for reconsideration by the Court of Appeals. The Supreme Court shall expedite its review of the Court of Appeals’ summary determination under this subsection.

(4)(a) The trial court’s authority to proceed with a case under subsection (2) of this section shall end when the appellate court has made an express determination that an appeal has been taken from an appealable order or judgment, all means for obtaining review of that determination under subsection (3) of this section have been exhausted, and the State Court Administrator at the direction of the court has mailed copies of the final appellate court determination to the trial court and the parties; otherwise, the trial court’s jurisdiction shall continue.

(b) No action by the trial court taken pursuant to subsections (1) and (2) of this section, except for entry of judgment, shall be void solely because an appellate court later determines that a notice of appeal was filed from an appealable decision. [Formerly 19.034]
