In any case before a military commission in which the United States seeks to delete, withhold, or otherwise obtain other relief with respect to the discovery of or access to any classified information, the trial counsel shall submit a declaration invoking the United States’ classified information privilege and setting forth the damage to the national security that the discovery of or access to such information reasonably could be expected to cause. The declaration shall be signed by a knowledgeable United States official possessing authority to classify information.

Upon the submission of a declaration under paragraph (1), the military judge may not authorize the discovery of or access to such classified information unless the military judge determines that such classified information would be noncumulative, relevant, and helpful to a legally cognizable defense, rebuttal of the prosecution’s case, or to sentencing, in accordance with standards generally applicable to discovery of or access to classified information in Federal criminal cases. If the discovery of or access to such classified information is authorized, it shall be addressed in accordance with the requirements of subsection (b).

The military judge shall permit the trial counsel to make a request for an authorization under paragraph (1) in the form of an ex parte presentation to the extent necessary to protect classified information, in accordance with the practice of the Federal courts under the Classified Information Procedures Act (18 U.S.C. App.). If the military judge enters an order granting relief following such an ex parte showing, the entire presentation (including the text of any written submission, verbatim transcript of the ex parte oral conference or hearing, and any exhibits received by the court as part of the ex parte presentation) shall be sealed and preserved in the records of the military commission to be made available to the appellate court in the event of an appeal.

The military judge shall grant the request of the trial counsel to substitute a summary or to substitute a statement admitting relevant facts, or to provide other relief in accordance with paragraph (1), if the military judge finds that the summary, statement, or other relief would provide the accused with substantially the same ability to make a defense as would discovery of or access to the specific classified information.
