Ga. Code. Jud. Cond. 3.4
Judges should not accept appointment to a governmental committee, commission, or other position that is concerned with issues of fact or policy on matters other than the improvement of the law, the legal system, or the administration of justice, if acceptance of such appointment might reasonably cast doubt upon their impartiality or demean the judge's office.
Commentary:
Valuable services have been rendered in the past to the states and the nation by judges appointed by the executive to undertake important extrajudicial assignments. The appropriateness of conferring these assignments on judges must be reassessed, however, in light of the demands on judicial officers created by today's crowded dockets and the need to protect the courts from involvement in extra-judicial matters that may prove to be controversial. Judges should not be expected or permitted to accept governmental appointments that could interfere with the effectiveness and independence of the judiciary.
