32 CFR 1801.43: Determination(s) by Office Chiefs.

Each Office Chief in charge of an office which originated or has an interest in any of the records subject to the appeal, or designee, is a required party to any appeal; other interested parties may become involved through the request of the Coordinator when it is determined that some or all of the information is also within their official cognizance. These parties shall respond in writing to the Coordinator with a finding as to the exempt or non-exempt status of the information including citations to the applicable exemption and/or their agreement or disagreement as to the requested amendment and the reasons therefore. Each response shall be provided expeditiously on a “first-in, first-out” basis taking into account the business requirements of the parties and consistent with the information rights of members of the general public under the various information review and release laws.
