Orders From Other Jurisdictions : Upon receipt of information indicating that an attorney licensed to practice law in Texas has been disciplined in another jurisdiction , including by any federal court or federal agency , the Chief Disciplinary Counsel shall diligently seek to obtain a certified copy of the order or judgment of discipline from the other jurisdiction, and file it with the Board of Disciplinary Appeals along with a petition requesting that the attorney be disciplined in Texas. A certified copy of the order or judgment is prima facie evidence of the matters contained therein, and a final adjudication in another jurisdiction that an attorney licensed to practice law in Texas has committed Professional Misconduct is conclusive for the purposes of a Disciplinary Action under this Part, subject to the defenses set forth in Rule 9.04 below. For purposes of this Part, "discipline" by a federal court or federal agency means a public reprimand, suspension, or disbarment; the term does not include a letter of "warning" or "admonishment" or a similar advisory by a federal court or federal agency.
