W. Va. Const. art. IX, § 10

Terms of office of county commissioners. The commissioners shall be elected by the voters of the county, and hold their office for a term of six years, except that at the first meeting of said commissioners they shall designate by lot, or otherwise in such manner as they may determine, one of their number, who shall hold his office for a term of two years, one for four years, and one for six years, so that one shall be elected every two years; but no two of said commissioners shall be elected from the same magisterial district. If two or more persons residing in the same district shall receive the greater number of votes cast at any election, then only the one of such persons receiving the highest number shall be declared elected, and the person living in another district, who shall receive the next highest number of votes, shall be declared elected. Said commissioners shall annually elect one of their number as president. The commissioners of said commissions, now in office, shall remain therein for the term for which they have been elected, unless sooner removed therefrom, in the manner prescribed by law.
