29 C.F.R. § 2704.204
Ordinarily, the net-worth and annual-receipts exhibits will be included in the public record of the proceeding. However, an applicant that objects to public disclosure of information in any portion of such exhibits and believes there are legal grounds for withholding the information from disclosure may submit that portion of the exhibit directly to the administrative law judge in a sealed envelope labeled "Confidential Financial Information," accompanied by a motion to withhold the information from public disclosure. The motion shall describe the information sought to be withheld and explain, in detail, why it falls within one or more of the specific exemptions from mandatory disclosure under the Freedom of Information Act, 5 U.S.C. 552(b)(1)-(9) , why public disclosure of the information would adversely affect the applicant, and why disclosure is not required in the public interest. The material in question shall be served on counsel representing the Secretary of Labor against whom the applicant seeks an award, but need not be served on any other party to the proceeding. If the administrative law judge finds that the information should not be withheld from disclosure, it shall be placed in the public record of the proceeding. Otherwise, any request to inspect or copy the exhibit shall be disposed of in accordance with the established procedures under the Freedom of Information Act ( 29 CFR part 2702 ).
