Except when duly subpoenaed, a judicial appointee 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.

[1] A judicial appointee who, without being subpoenaed, testifies as a character witness abuses the prestige of the position to advance the interests of another. See Rule 18-201.3. Except in unusual circumstances where the demands of justice require, a judicial appointee should discourage a party from requiring the judicial appointee to testify as a character witness.
