29 CFR § 2702.5 - Right to appeal.

(a) Generally. Any requester adversely affected by a final decision of the Commission's FOIA Office may file an appeal of that decision within 90 days of the initial determination. All FOIA appeals must be in writing and shall be made to the Chair of the Commission. Sitting Commissioners will decide appeals within 20 business days after receipt. In the event that a sitting Commissioner is the subject of the disputed FOIA records or has a substantial interest in the disputed records, that Commissioner should be recused from consideration of said FOIA appeal. In the event of a tie vote of those Commissioners, the FOIA Office's initial determination will be deemed approved by the Commission. Appeals must be submitted via email, mail, fax or hand delivery to FOIA-appeals@fmshrc.gov, Federal Mine Safety and Health Review Commission, 1331 Pennsylvania Avenue NW, Suite 520N, Washington, DC 20004–1710, Fax: 202–434–9944.

(b) Appeal of denial or partial denial of information request. The appeal must include a copy of the initial FOIA request, a copy of the determination denying the request in whole or in part, and a detailed statement explaining why the initial determination should be reversed. Any records to be disclosed by the Commission to the requester shall be provided with the letter setting forth the determination as to the appeal or shall be sent as soon as possible thereafter.

(c) Appeal of denial of request to expedite. The appeal must include a copy of the initial request to expedite, a copy of the determination denying the request, and a detailed explanation demonstrating a compelling need as stated in § 2702.4(b)(3). The Commission will provide expeditious consideration of administrative appeals of determinations on whether to provide expedited processing. Once a determination has been made to grant expedited processing, the Commission will process the request as soon as practicable.

(d) Appeal of denial of fee waiver or reduction. The appeal must include a copy of the initial fee waiver/reduction request, a copy of the determination denying the request, and a detailed statement explaining how the request satisfies one or more requirements in § 2702.10(b).

(e) Denial of appeal. If an appeal is denied, the Commission's notice of denial shall inform the requester of the right to obtain judicial review of the Commission's action under 5 U.S.C. 552(a)(4)(B)–(G). The requester may appeal the Commission's decision by filing a complaint in the district court of the United States in the district in which the complainant resides, or has its principal place of business, or in which the agency records are situated, or in the District of Columbia.
