Colo. Code. Jud. Cond. 3.9
COMMENT
[1] This Rule does not prohibit a judge from participating in arbitration, mediation, or settlement conferences performed as part of assigned judicial duties. Rendering dispute resolution services apart from those duties, whether or not for economic gain, is prohibited unless it is expressly authorized by law.
ETHICS OPINIONS Active judge soon to retire and participate in the Senior Judge Program should refrain from setting or hearing private mediations until after he retires. Colo. J.E.A.B. Op. 06-09. A judge may, with the consent of the parties, confer separately with the parties and their lawyers in an effort to mediate or settle matters pending before the judge. Trial judges conducting settlement conferences in their own cases must, however, have a heightened awareness of the appearance that the parties might feel improper pressure to settle or that the judge will no longer be impartial if the case fails to settle. Alaska Ad. Op. 2006-01.
