12 CFR § 1080.8 - Withholding requested material.
(a) Any person withholding material responsive to a civil investigative demand or any other request for production of material shall assert a claim of privilege not later than the date set for the production of material. Such person shall, if so directed in the civil investigative demand or other request for production, submit, together with such claim, a schedule of the items withheld which states, as to each such item, the type, specific subject matter, and date of the item; the names, addresses, positions, and organizations of all authors and recipients of the item; and the specific grounds for claiming that the item is privileged. The person who submits the schedule and the attorney stating the grounds for a claim that any item is privileged must sign it.
(b) A person withholding material solely for reasons described in this subsection shall comply with the requirements of this subsection in lieu of filing a petition for an order modifying or setting aside a civil investigative demand pursuant to section 1080.6(e).
(c) Disclosure of privileged or protected information or communications produced pursuant to a civil investigative demand shall be handled as follows:
(1) The disclosure of privileged or protected information or communications shall not operate as a waiver with respect to the Bureau if:
(i) The disclosure was inadvertent;
(ii) The holder of the privilege or protection took reasonable steps to prevent disclosure; and
(iii) The holder promptly took reasonable steps to rectify the error, including notifying a Bureau investigator of the claim of privilege or protection and the basis for it.
(2) After being notified, the Bureau investigator must promptly return, sequester, or destroy the specified information and any copies; must not use or disclose the information until the claim is resolved; must take reasonable steps to retrieve the information if he or she disclosed it before being notified; and, if appropriate, may sequester such material until such time as a hearing officer or court rules on the merits of the claim of privilege or protection. The producing party must preserve the information until the claim is resolved.
(3) The disclosure of privileged or protected information or communications shall waive the privilege or protection with respect to the Bureau as to undisclosed information or communications only if:
(i) The waiver is intentional;
(ii) The disclosed and undisclosed information or communications concern the same subject matter; and
(iii) They ought in fairness to be considered together.
