When a party files a brief in the Court of Appeals, if the party is aware of another case pending in an appellate court that arises out of the same case or consolidated case, or that involves the same transaction or event, the party must file a notice with the Court of Appeals identifying the related case by case title and appellate case number. The notice must be a separate document from the party's brief. A party may likewise notify the Court of Appeals if the party is aware of another case pending in an appellate court that raises the same or a closely related issue. A party need not notify the Court of Appeals of a related case if another party has already done so.
Or. R. App. P. 8.47
