Legislative sessions The Senate meets in regular session in east wing of the
Oklahoma State Capitol in
Oklahoma City, from early February to the last Friday in May. Special sessions may be called by the
governor of Oklahoma, or by supermajority vote of the legislature. Unlike their counterparts in the
Oklahoma House of Representatives, state senators are not restricted on introduction of bills and resolutions.
Advise and consent The Oklahoma Senate advises and consents to numerous appointments of the Governor, including the entire
Governor's Cabinet. Nominations are heard by respective standing committees rather than through a committee on nominations.
Redistricting Originally, the Oklahoma Constitution based Senate districts on Oklahoma's counties. The 19 most populous counties, as determined by the most recent federal census, were each to elect one senator. The 58 less populous counties were to be joined into 29 two-county districts, each of which was to elect one senator. In apportioning the Senate, the Oklahoma Constitution required that consideration be given to population, compactness, area, political units, historical precedents, economic and political interests, contiguous territory and other major factors, to the extent feasible. In 1964, the
United States Supreme Court ruled this method violated the federal Constitution. Since then, every ten years, the Oklahoma Senate is responsible for passing into law new district boundaries for the Oklahoma House of Representatives, Oklahoma Senate and Oklahoma Congressional delegation. The Senate and House have traditionally drawn their own lines without any comment from the other body and work together with the Congressional delegation to draw lines appropriate for the next election. The Governor must sign these bills into law or a statewide panel is convened to draw the disputed lines.
Court of impeachment The Oklahoma Senate serves a dual role as both a legislative body and as a judicial court. As the court of
impeachment, it is an independent court in the
Oklahoma court system. Impeachment charges are brought by the
Oklahoma House of Representatives, but
heard by the court of impeachment, with Oklahoma's chief justice presiding over the court. If the chief justice or a member of the
Oklahoma Supreme Court is charged with impeachment, a state senator can preside over the court of impeachment. Impeachment charges may only be brought against the governor, other statewide elected state officials and justices of the
Oklahoma Supreme Court for willful neglect of duty, corruption in office, habitual drunkenness, incompetency, or any offense involving moral turpitude committed while in office. Impeached officials are immediately suspended in discharging their duties. Should the impeachment fail, the official returns to their duties. If the impeachment is successful and the defendant found guilty, the official is removed from office. ==Party composition==
