Okla. Stat. tit. 20, app I R. 11
From time to time the Supreme Court shall declare by a directive in what cities, other than the county seat, a district court or one of its divisions shall hold sessions. These directives shall be based on statistical reports collected through the office of the Administrative Director of the Courts. Until such directive is issued by the Supreme Court, nothing provided in this rule shall be construed to restrict the authority of the Presiding Judge, or of the district and associate district judges, to designate either by rule or directive that a district court, or one of its divisions, shall sit in a place other than the county seat. Rules or directives so made either by the Presiding Judge or by the district and associate district judges shall be based on statistical data. A copy of all such orders, rules, and directives and the data supporting them shall be filed in the office of the Administrative Director of the Courts. Appropriate notice of such declaration shall be given to the lawyers and to the public. 20 O.S.2001, § 95.1.
