Effective - 28 Aug 1999   476.682. Retired judge serving as senior judge or commissioner, compensation — expenses, how paid — computation of service as retirement credit, adjustment, exception — annual report, content. — 1. Any person assigned as a senior judge or senior commissioner pursuant to Section 26 of Article V of the Missouri Constitution and who has served in this state an aggregate of at least two years, continuously or otherwise, as a judge or commissioner, shall receive for each day of service an amount equal to fifty percent of the current annual salary of the office from which the judge or senior commissioner retired attributable to one day of service. Notwithstanding the foregoing, any judge or commissioner who has retired prior to August 28, 1999, who serves subsequent to said date as a senior judge or commissioner may receive compensation pursuant to this section regardless of their length of service; and no senior judge or senior commissioner shall receive less daily compensation than an amount, that when added to the daily amount of annual compensation payable pursuant to sections 476.450 to 476.595, is less than one hundred percent of the current annual salary of the office from which the judge or commissioner retired attributable to one day of service. For purposes of this subsection, one year shall equal two hundred thirty-five days. No senior judge or senior commissioner shall receive compensation pursuant to this subsection in a total amount that when such compensation is added to the annual compensation, salary or retirement compensation payable pursuant to sections 476.450 to 476.595, the sum is greater than the current annual salary of the office from which the judge or commissioner retired.  2. A senior judge or senior commissioner assigned pursuant to Section 26 of Article V of the Missouri Constitution for service outside the county where he or she resides shall be reimbursed for his or her travel and other actual and necessary expenses incurred in the performance of his or her services.  3. On or before the tenth day of each month a senior judge or senior commissioner shall certify to the state courts administrator the period during the previous month during which he or she was assigned services and, if such services were completed, the date thereof and at the same time shall certify his or her expenses incurred and allowable under this section. The state courts administrator shall then issue a warrant to the state treasurer for the payment of the salary and expenses to the extent and within limitations provided for in this section. The state treasurer upon receipt of such warrant shall pay the same out of any appropriations made for this purpose on the last day of the month during which the warrant was received by him or her.  4. On or before the twentieth day of each month the state courts administrator shall certify the period of service reported by each senior judge or senior commissioner pursuant to subsection 3 of this section to the Missouri state employees' retirement system. Any senior judge or senior commissioner accumulating two hundred thirty-five days of such service shall receive credit for one year of judicial service for purposes of sections 476.520 and 476.545, for each two hundred thirty-five days of service certified by the state courts administrator to the Missouri state employees' retirement system, except, if a pro rata portion of two hundred thirty-five days would cause the senior judge's or senior commissioner's total judicial service to equal twelve years, the Missouri state employees' retirement system shall credit the service at the time the pro rata portion is certified. Upon receipt of such certification, the retirement benefit of the senior judge or senior commissioner shall be recalculated to reflect the attainment of twelve years; the adjusted benefit will become effective the first of the month following certification.  5. Notwithstanding the provisions of section 476.510 or 476.565, no person shall receive benefits pursuant to the provisions of this section if the person is engaged in the private practice of law or doing a law business.  6. The judicial conference of the state of Missouri shall annually report on the use of senior judges and senior commissioners pursuant to this section. Such report shall include at least the number of senior judges and senior commissioners assigned, the number of cases assigned and disposed of by senior judges and senior commissioners, and the expenditures made for that purpose. ­­-------- (L. 1988 S.B. 425 § 2, A.L. 1994 H.B. 1149, A.L. 1999 S.B. 1, et al.)
