Okla. Stat. tit. 20 § 30.16
At the General Election next before a term expires, any Judge of the Court of Civil Appeals may seek retention in office by filing with the Secretary of State, not less than sixty (60) days before the date of the election, a declaration of candidacy to succeed himself or herself. At the election, there shall be submitted to the qualified electors of the state, on a separate ballot, without party designation, this question:
"Shall (Here insert name of Judge) of the Court of Civil Appeals be retained in Office?"
/___/ YES
/___/ NO
The question shall be decided by a majority of those voting thereon. If the decision is "yes" the Judge shall be retained in office for the next ensuing six-year term. If the decision is "no", or if no declaration of candidacy is filed, the office shall be vacant upon expiration of the term then being served, and the former Judge shall not be eligible for appointment to succeed himself or herself. Retention in office may be sought for successive terms without limit as to number, except for retirement as may be provided by the Legislature for a maximum retirement age.
