32 CFR 725.2 - Policy.
(a) It is DON policy that official factual information, both testimonial and documentary, should be made reasonably available for use in Federal courts, state courts, foreign courts, and other governmental proceedings unless that information is classified, privileged, or otherwise protected from public disclosure.
(b) DON personnel, as defined in § 725.4(b), however, shall not provide such official information, testimony, or documents, submit to interview, or permit a view or visit, without the authorization required by this part.
(c) DON personnel shall not provide, with or without compensation, opinion or expert testimony concerning official DON or Department of Defense (DOD) information, subjects, personnel, or activities, except on behalf of the United States or a party represented by the Department of Justice, or with the written special authorization required by this part.
(d) Section 725.2(b) and (c) constitute a regulatory general order, applicable to all DON personnel individually, and need no further implementation. A violation of those provisions is punishable under the Uniform Code of Military Justice for military personnel and is the basis for appropriate administrative procedures with respect to civilian employees. Moreover, violations of this instruction by DON personnel may, under certain circumstances, be actionable under 18 U.S.C. 207.
(e) Upon a showing by a requester of exceptional need or unique circumstances, and that the anticipated testimony will not be adverse to the interests of the DON, DOD, or the United States, the General Counsel of the Navy, the Judge Advocate General of the Navy, or their respective delegates may, in their sole discretion, and pursuant to the guidance contained in this instruction, grant such written special authorization for DON personnel to appear and testify as expert or opinion witnesses at no expense to the United States.
