A rule of professional conduct that bars a lawyer from knowingly making a false statement of fact or law to a tribunal or failing to correct a material false statement previously made to the tribunal by the lawyer. The rule further requires reasonable remedial measures, including disclosure if necessary, when a lawyer knows a client intends to engage in criminal or fraudulent conduct related to the proceeding or when the lawyer knows of directly adverse controlling authority not disclosed by opposing counsel.
