Oregon Revised Statutes Procedure in Civil Proceedings § 19.420

(1) Upon an appeal, the court to which the appeal is made may affirm, reverse or modify the judgment or part thereof appealed from as to any or all of the parties joining in the appeal, and may include in such decision any or all of the parties not joining in the appeal, except a codefendant of the appellant against whom a several judgment might have been given in the court below; and may, if necessary and proper, order a new trial.

(2) Where in the trial court a motion for judgment notwithstanding the verdict and a motion for a new trial were made in the alternative, and an appeal is taken from a judgment notwithstanding the verdict or an order granting a new trial, the court to which the appeal is made may consider the correctness of the ruling of the trial court on either or both motions if such ruling is assigned as erroneous in the brief of any party affected by the appeal, without the necessity of a cross-appeal.

(3) Whenever it appears that an appeal cannot be prosecuted, by reason of the loss or destruction, through no fault of the appellant, of the reporter's notes or audio records, or of the exhibits or other matter necessary to the prosecution of the appeal, the judgment appealed from may be reversed and a new trial ordered as justice may require.
