W. Va. Const. art. VIII, § 2

Supreme court of appeals. The supreme court of appeals shall consist of five justices. A majority of the justices of the court shall constitute a quorum for the transaction of business. The justices shall be elected by the voters of the state for a term of twelve years, unless sooner removed or retired as authorized in this article. The Legislature may prescribe by law whether the election of such justices is to be on a partisan or nonpartisan basis. Provision shall be made by rules of the supreme court of appeals for the selection of a member of the court to serve as chief justice thereof. If the chief justice is temporarily disqualified or unable to serve, one of the justices of the court designated in accordance with the rules of the court shall serve temporarily in his stead. When any justice is temporarily disqualified or unable to serve, the chief justice may assign a judge of a circuit court or of an intermediate appellate court to serve from time to time in his stead.
