95-07 Where a client knowingly testifies falsely regarding a material matter and where the case remains pending before the court for decision when the client’s attorney learns that the client testified falsely, the attorney has a duty to call upon the client to reveal the false testimony to the court prior to the court’s decision, and if the client refuses, the attorney must make the disclosure.

81-01 An attorney must maintain his client’s confidences if he finds out from his client that his client made false representations to him which resulted in an agreement disposing of a criminal case. If, however, the attorney receives information from someone other than his client that clearly establishes his client intentionally committed a fraud upon a person or tribunal, the attorney must call upon his client to rectify the same. If his client refuses or is unable to do so, the attorney must himself reveal the fraud to the affected person or tribunal.
