§ 5. Notice of defendant’s intention to disclose classified information
(a)
Notice by Defendant.—
If a defendant reasonably expects to disclose or to cause the disclosure of classified information in any manner in connection with any trial or pretrial proceeding involving the criminal prosecution of such defendant, the defendant shall, within the time specified by the court or, where no time is specified, within thirty days prior to trial, notify the attorney for the United States and the court in writing. Such notice shall include a brief description of the classified information. Whenever a defendant learns of additional classified information he reasonably expects to disclose at any such proceeding, he shall notify the attorney for the United States and the court in writing as soon as possible thereafter and shall include a brief description of the classified information. No defendant shall disclose any information known or believed to be classified in connection with a trial or pretrial proceeding until notice has been given under this subsection and until the United States has been afforded a reasonable opportunity to seek a determination pursuant to the procedure set forth in section 6 of this Act, and until the time for the United States to appeal such determination under section
7 has expired or any appeal under section
7 by the United States is decided.
(b)
Failure to Comply.—
If the defendant fails to comply with the requirements of subsection (a) the court may preclude disclosure of any classified information not made the subject of notification and may prohibit the examination by the defendant of any witness with respect to any such information.
