Oklahoma Types of Extraordinary Writs; Jurisdiction is a set of procedures that allow for the review of a court decision by the state's highest court. It consists of two types of writs: writ of certiorari and writ of mandamus. A writ of certiorari is an order from the Supreme Court of Oklahoma to a lower court to send the record of a given case for review. This type of writ is typically sought to reverse or modify a decision of a trial court. A writ of mandamus is an order from the Supreme Court of Oklahoma to a lower court, public officer, or other authority to perform an act which they are required to do by law. This type of writ is typically sought to force a lower court to act when the lower court has failed to do so. Both types of writs are issued by the Supreme Court of Oklahoma to provide a review of a lower court's decision on a matter of law or jurisdiction. The Supreme Court of Oklahoma has exclusive jurisdiction over all writs of extraordinary relief and may issue such writs as it deems necessary and appropriate.
