Repräsentantenhaus von Oklahoma
Article Five of the Oklahoma Constitution authorizes the Oklahoma House of Representatives to elect a speaker at the beginning of each regular session. Unlike the Speaker of the United States House of Representatives, the Speaker of the Oklahoma House of Representatives is required to be a member of the Oklahoma House of Representatives. The Oklahoma Constitution also allows for the election of a Speaker of the Oklahoma House of Representatives at "times as may be necessary," which include in the event of the resignation or death of a speaker or during special sessions.
