Oklahoma constitution
Article V: legislative power
Section 11c

Any qualified elector may seek a review of any apportionment order of the Commission, or apportionment law of the legislature, within sixty days from the filing thereof, by filing in the Supreme Court of Oklahoma a petition which must set forth a proposed apportionment more nearly in accordance with this Article. Any apportionment of either the Senate or the House of Representatives, as ordered by the Commission, or apportionment law of the legislature, from which review is not sought within such time, shall become final. The court shall give all cases involving apportionment precedence over all other cases and proceedings; and if said court be not in session, it shall convene promptly for the disposal of the same.
