Minn. Stat. § 490.133
If a judge to whom or to whose survivors benefits would be payable under sections 490.101 to 490.12, is elected or appointed to the court of appeals, that judge and the judge's survivors, shall continue to be eligible for benefits under those sections and not under sections 490.121 to 490.132. In that case, the service of the judge in the court of appeals shall be added to the service as district judge, probate judge, or judge of any other court of record in determining eligibility and the compensation of a judge of the court of appeals at the time of the judge's death, disability, or retirement shall be the "compensation allotted to the office" for the purposes of calculating benefit amounts. All other judges of the court of appeals and their survivors shall be subject to the retirement and survivor's annuity provisions of sections 490.121 to 490.132.
