Louisiana Code of Civil Procedure Tit. I, Art. 371. Attorney

A. An attorney is an officer of the court. An attorney shall at all times act with decorum and in a manner consistent with the dignity and authority of the court and the role that the attorney should play in the administration of justice.

B. An attorney shall treat the court, its officers, jurors, witnesses, the 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, including evidence that is artificially generated or altered by any means; and shall not knowingly make any misrepresentation or otherwise impose upon or deceive the court.

C. An attorney shall exercise reasonable diligence to verify the authenticity of evidence before offering it to the court. If an attorney knew or should have known through the exercise of reasonable diligence that evidence was false or artificially manipulated, the offering of that evidence without disclosure of that fact shall be considered a violation of this Article.

D. For a violation of any of the provisions of this Article, the attorney is subject to punishment for contempt of court and further disciplinary action as is otherwise provided by law.
