11.303    Candor toward the tribunal.

  • (a) A practitioner shall not knowingly:
    • (1) Make a false statement of fact or law to a tribunal or fail to correct a false statement of material fact or law previously made to the tribunal by the practitioner;
    • (2) Fail to disclose to the tribunal legal authority in the controlling jurisdiction known to the practitioner to be directly adverse to the position of the client and not disclosed by opposing counsel in an inter partes proceeding, or fail to disclose such authority in an ex parte proceeding before the Office if such authority is not otherwise disclosed; or
    • (3) Offer evidence that the practitioner knows to be false. If a practitioner, the practitioner’s client, or a witness called by the practitioner, has offered material evidence and the practitioner comes to know of its falsity, the practitioner shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal. A practitioner may refuse to offer evidence that the practitioner reasonably believes is false.
  • (b) A practitioner who represents a client in a proceeding before a tribunal and who knows that a person intends to engage, is engaging or has engaged in criminal or fraudulent conduct related to the proceeding shall take reasonable remedial measures, including, if necessary, disclosure to the tribunal.
  • (c) The duties stated in paragraphs (a) and (b) of this section continue to the conclusion of the proceeding, and apply even if compliance requires disclosure of information otherwise protected by § 11.106.
  • (d) In an ex parte proceeding, a practitioner shall inform the tribunal of all material facts known to the practitioner that will enable the tribunal to make an informed decision, whether or not the facts are adverse.
  • (e) In a proceeding before the Office, a practitioner shall disclose to the Office information necessary to comply with applicable duty of disclosure provisions.
