A judge shall not testify as a character witness in a judicial, administrative, or other adjudicatory proceeding or otherwise vouch for the character of a person in a legal proceeding, except when duly summoned. Unless there are unusual circumstances under which the demands of justice require, a judge should discourage a party from requiring the judge to testify as a character witness.
