Okla. Stat. tit. 20, § 20-1104: Retirement compensation

Each justice or judge who is a member of The Uniform Retirement

System for Justices and Judges upon retirement after June 30, 2004,

shall be entitled to receive as retirement compensation, until

changed by the Legislature, an annual amount, each monthly payment

of which shall be in an amount equal to four percent (4%) of the

average monthly salary received by him or her as a justice or judge

based on the highest three (3) years of active service multiplied by

the number of total years of service and reduced according to the

elected survivor option, if any. The amounts of compensation

reported to the Oklahoma Public Employees Retirement System for the

Uniform Retirement System for Justices and Judges, by the Office of

Management and Enterprise Services prior to June 30, 2004, may be

conclusively presumed as valid regarding the source of the

compensation reported as salary for purposes of the accuracy of the

employees' contributions and the computation of salary for the

calculation of benefits. This presumption shall not include any

computation error made by the Office of Management and Enterprise

Services or the Oklahoma Public Employees Retirement System on

behalf of the Uniform Retirement System for Justices and Judges.

Provided, however, that no justice or judge retiring after June 30,

2004, may receive a monthly retirement benefit in excess of one

hundred percent (100%) of the average monthly salary based on the

highest three (3) years of active service and found applicable to

such justice or judge at the time of retirement. Retirement

compensation shall be payable monthly out of the State Judicial

Retirement Fund by warrants prepared by the Executive Director of

the Public Employees Retirement System and issued by the State

Treasurer.
