 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.Each justice must be at least 30 years old, have previously been licensed as an attorney for five years, and have lived for at least one year in the Supreme Court judicial district from which they are selected.
