ETHICS OPINIONS Judge may not participate in a local legal service's call-a-lawyer program by providing advice to callers, anonymous or otherwise, because doing so would constitute the practice of law. The judge may, however, engage in activities intended to encourage attorneys to perform pro bono services or act in an advisory capacity to the legal services pro bono program. Colo. J.E.A.B. Op. 06-02. A judge may serve as a National Guard judge advocate if the judge's role is limited to performing only those duties that do not resemble services provided by civilian attorneys for members of the military. Judges may not take any actions while serving as a National Guard judge advocate that would give the impression that the judge is an advocate on matters that concern the civilian justice system. Ak. Ad. Op. 2007-01.
