The Oregon Supreme Court (OSC) is the highest state court in the U.S. state of Oregon. The only court that may reverse or modify a decision of the Oregon Supreme Court is the Supreme Court of the United States. The OSC holds court at the Oregon Supreme Court Building in Salem, Oregon, near the capitol building on State Street. The building was finished in 1914 and also houses the state's law library, while the courtroom is also used by the Oregon Court of Appeals.
