An attorney at law is an officer of the court. He shall conduct himself at all times with decorum, and in a manner consistent with the dignity and authority of the court and the role which he himself should play in the administration of justice.
He shall treat the court, its officers, jurors, witnesses, opposing party, and opposing counsel with due respect; shall not interrupt opposing counsel, or otherwise interfere with or impede the orderly dispatch of judicial business by the court; shall not knowingly encourage or produce false evidence; and shall not knowingly make any misrepresentation, or otherwise impose upon or deceive the court.
For a violation of any of the provisions of this article, the attorney at law subjects himself to punishment for contempt of court, and such further disciplinary action as is otherwise provided by law.
