12 C.F.R. § 1101.5
No person shall testify, in court or otherwise, as a result of activities on behalf of the Council without prior written authorization from the Council. This section shall not restrict the authority of a Council member to testify before Congress on matters within his or her official responsibilities as a Council member. No person shall furnish documents reflecting information of the Council in compliance with a subpoena, order, or otherwise, without prior written authorization from the Council. The Council may authorize testimony or production of documents after the litigant (or the litigant's attorney) submits an affidavit to the Council setting forth the interest of the litigant and the testimony or documents desired. Authorization to testify or produce documents is limited to authority expressly granted by the Council. When the Council has not authorized testimony or production of documents, the individual to whom the subpoena or order has been directed will appear in court and respectfully state that he or she is unable to comply further with the subpoena or order by reason of this section.
