Section 4.31 - Request for limiting disclosure of confidential information(a) If any person submitting a document in a proceeding under this part claims that some or all of the information contained in that document is exempt from the mandatory public disclosure requirements of the Freedom of Information Act (5 U.S.C. 552 ), is information referred to in section 1905 of title 18 of the United States Code (disclosure of confidential information), or is otherwise exempt by law from public disclosure, the person: (1) Must indicate in the document that it is exempt, or contains information which is exempt, from disclosure;(2) Must request the presiding officer or appeals board not to disclose such information except to the parties to the proceeding under the conditions provided in paragraphs (b) and (c) of this section, and must serve the request upon the parties to the proceeding. The request shall include the following items:(i) A copy of the document from which has been deleted the information for which the person requests nondisclosure; if it is not practicable to submit such copy of the document because deletion of the information would render the document unintelligible, a description of the document may be substituted;(ii) A statement specifying why the information is confidential, if the information for which nondisclosure is requested is claimed to come within the exception in 5 U.S.C. 552(b)(4) for trade secrets and commercial or financial information:(iii) A statement specifying the justification for nondisclosure, if the information for which nondisclosure is requested is not within the exception in 5 U.S.C. 552(b)(4) .(b) If information is submitted in accordance with paragraph (a) of this section, the information will not be disclosed except as provided in the Freedom of Information Act, in accordance with part 2 of this title, or upon request from a party to the proceeding under the restrictions stated in paragraph (c) of this section.(c) At any time, a party may request the presiding officer or appeals board to direct a person submitting information under paragraph (a) of this section to provide that information to the party. The presiding officer or board will so direct, unless paragraph (d) of this section is applicable, if the party requesting the information agrees under oath in writing:(1) Not to use or disclose the information except in the context of the proceeding conducted pursuant to this part; and(2) Not to retain in any format, and to return all physical copies of the information at the conclusion of the proceeding to the person submitting the information under paragraph (a) of this section.(d) If any person submitting a document in a proceeding under this Part other than a hearing conducted pursuant to 5 U.S.C. 554 claims that a disclosure of information in that document to another party to the proceeding is prohibited by law, notwithstanding the protection provided under paragraph (c) of this section, such person:(1) Must indicate in the original document that it contains information of which disclosure is prohibited;(2) Must request that the presiding officer or appeals board review such evidence as a basis for its decision without disclosing it to the other party or parties, and serve the request upon the parties to the proceeding. The request shall include a copy of the document or description as required by paragraph (a)(2)(i) of this section and state why disclosure is prohibited, citing pertinent statutory or regulatory authority. If the prohibition on disclosure is intended to protect the interest of a person who is not a party to the proceeding, the party making the request must demonstrate that such person refused to consent to the disclosure of the evidence to other parties to the proceeding.(3) If the presiding officer or an appeals board denies the request, the person who made the request shall be given an opportunity to withdraw the evidence before it is considered by the presiding official or board unless a Freedom of Information Act request, administrative appeal from the denial of a request, or lawsuit seeking release of the information is pending.(e) If the person submitting a document does not submit the copy of the document or description required by paragraph (a)(2)(i) or (d)(2) of this section, the presiding officer or appeals board may assume that there is no objection to public disclosure of the document in its entirety.(f) Where a decision by a presiding officer or appeals board is based in whole or in part on evidence not included in the public record or disclosed to all parties, the decision shall so state, specifying the nature of the evidence and the provision of law under which disclosure was denied, and the evidence so considered shall be retained under seal as part of the official record.53 FR 49661, Dec. 9, 1988, as amended at 88 FR 5792 , Jan. 30, 2023
