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. However, a judge may appear voluntarily at a public hearing of the Judicial Nominating Commission and at judicial selection or confirmation proceedings and may testify concerning a judicial candidate.*
R.i. Sup. Ct. R. 3.3
COMMENT
[1] A judge who, without being subpoenaed, testifies as a character witness abuses the prestige of judicial office to advance the interests of another. See Rule 1.3.
