How vacancies are filled in Oklahoma

See also: How vacancies are filled in state legislatures


If there is a vacancy in the Oklahoma State Legislature, the governor must call a special election no later than 30 days after the vacancy occurs. No special election can be called if the vacancy occurs in an even-numbered year and if the term of office will expire in that year. This second provision allows special elections to be held for outgoing senators with two or more years left in their terms.[1]

If a senator announces his or her resignation before March 1 but the effective date lies between the general election and the new session, a special election can be held on the general election dates. The winner of this election will take office upon the senator's official resignation. This only applies to senators with two or more years remaining in their terms.[1]
