16 CFR 3.38A - Withholding requested material.
(a) Any person withholding material responsive to a subpoena issued pursuant to § 3.34 or § 3.36, written interrogatories requested pursuant to § 3.35, a request for production or access pursuant to § 3.37, or any other request for the production of materials under this part, shall assert a claim of privilege or any similar claim not later than the date set for production of the material. Such person shall, if so directed in the subpoena or other request for production, submit, together with such claim, a schedule which describes the nature of the documents, communications, or tangible things not produced or disclosed - and does so in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the claim. The schedule need not describe any material outside the scope of the duty to search set forth in § 3.31(c)(2) except to the extent that the Administrative Law Judge has authorized additional discovery as provided in that paragraph.
(b) A person withholding material for reasons described in § 3.38A(a) shall comply with the requirements of that subsection in lieu of filing a motion to limit or quash compulsory process.
