Generally, any record demanded by a subpoena duces tecum or appropriate court order can be released by a properly authorized Office of Inspector General employee, except for the following:
(a) Records required to remain confidential by the Freedom of Information Act, the Privacy Act, and parts 230 and 262 of this chapter,
(b) Records containing information relating to an employee's security or loyalty;
(c) Original records;
(d) Office of Inspector General criminal investigative reports, unless there is specific authorization by an authorizing official, after consulting with General Counsel to the Inspector General; and
(e) The Office of Inspector General Manual and other operating instructions issued to Office of Inspector General employees, unless there is specific authorization by an authorizing official, after consultation with the General Counsel to the Inspector General. If the requested information relates to confidential investigative techniques, confidential sources of information, or information that must be kept confidential under the Inspector General Act, 5 U.S.C. app. 3, because release of the information would adversely affect the duties and obligations or law enforcement mission of the Office of Inspector General, the subpoenaed official, through the Inspector General, or an authorizing official, may request an in camera, ex parte conference to determine the necessity for the release of the information.
