28 CFR 16.9: Appeals.
If you are dissatisfied with a component's response to your request, you may appeal an adverse determination denying your request, in any respect, to the Office of Information and Privacy, U.S. Department of Justice, Flag Building, Suite 570, Washington, DC 20530-0001. You must make your appeal in writing and it must be received by the Office of Information and Privacy within 60 days of the date of the letter denying your request. Your appeal letter may include as much or as little related information as you wish, as long as it clearly identifies the component determination (including the assigned request number, if known) that you are appealing. For the quickest possible handling, you should mark your appeal letter and the envelope “Freedom of Information Act Appeal.” Unless the Attorney General directs otherwise, a Director of the Office of Information and Privacy will act on behalf of the Attorney General on all appeals under this section, except that:
(1) In the case of an adverse determination by the Deputy Attorney General or the Associate Attorney General, the Attorney General or the Attorney General's designee will act on the appeal;
(2) An adverse determination by the Attorney General will be the final action of the Department; and
(3) An appeal ordinarily will not be acted on if the request becomes a matter of FOIA litigation.
The decision on your appeal will be made in writing. A decision affirming an adverse determination in whole or in part shall contain a statement of the reason(s) for the affirmance, including any FOIA exemption(s) applied, and will inform you of the FOIA provisions for court review of the decision. If the adverse determination is reversed or modified on appeal, in whole or in part, you will be notified in a written decision and your request will be reprocessed in accordance with that appeal decision.
If you wish to seek review by a court of any adverse determination, you must first appeal it under this section.
