28 CFR 700.23 - Notice of subpoenas and emergency disclosures.
(a) Subpoenas. When records pertaining to an individual are subpoenaed by a grand jury, court, or quasi-judicial authority, the official served with the subpoena shall be responsible for ensuring that written notice of its service is forwarded to the individual. Notice shall be provided within 10 working days of the service of the subpoena or, in the case of a grand jury subpoena, within 10 working days of its becoming a matter of public record. Notice shall be mailed to the last known address of the individual and shall contain the following information: The date the subpoena is returnable, the court or quasi-judicial authority to which it is returnable, the name and number of the case of proceeding, and the nature of the records sought. Notice of the service of a subpoena is not required if the system of records has been exempted from the notice requirement of 5 U.S.C. 552a(e)(8), pursuant to 5 U.S.C. 552a(j), by a Notice of Exemption published in the Federal Register.
(b) Emergency disclosures. If the record of an individual has been disclosed to any person under compelling circumstances affecting the health or safety of any person, as described in 5 U.S.C. 552a(b)(8), the individual to whom the record pertains shall be notified of the disclosure at his last known address within 10 working days. The notice of such disclosure shall be in writing and shall state the nature of the information disclosed, the person or agency to whom it was disclosed, the date of disclosure, and the compelling circumstances justifying the disclosure. The officer who made or authorized the disclosure shall be responsible for providing such notification.
