Oregon constitution
Article VII: judicial branch
Section 3

In actions at law, where the value in controversy shall exceed $750, the right of trial by jury shall be preserved, and no fact tried by a jury shall be otherwise re-examined in any court of this state, unless the court can affirmatively say there is no evidence to support the verdict. Until otherwise provided by law, upon appeal of any case to the supreme court, either party may have attached to the bill of exceptions the whole testimony, the instructions of the court to the jury, and any other matter material to the decision of the appeal. If the supreme court shall be of opinion, after consideration of all the matters thus submitted, that the judgment of the court appealed from was such as should have been rendered in the case, such judgment shall be affirmed, notwithstanding any error committed during the trial; or if, in any respect, the judgment appealed from should be changed, and the supreme court shall be of opinion that it can determine what judgment should have been entered in the court below, it shall direct such judgment to be entered in the same manner and with like effect as decrees are now entered in equity cases on appeal to the supreme court. Provided, that nothing in this section shall be construed to authorize the supreme court to find the defendant in a criminal case guilty of an offense for which a greater penalty is provided than that of which the accused was convicted in the lower court.
