 The Court on the Judiciary and the Court of Impeachment are courts that are independent of the administration of the Supreme Court; there is no appeal from these court decisions.The Oklahoma Supreme Court is Oklahoma’s court of last resort in all civil matters and all matters concerning the Oklahoma Constitution.It consists of nine justices appointed by the governor to serve life terms, but unlike U.S. Supreme Court justices, they are subject to an election every six years in which voters choose whether or not to retain them.
