(D) Evidence shall be admitted as authentic so long as
(i) the military judge of the military commission determines that there is sufficient basis to find that the evidence is what it is claimed to be; and
(ii) the military judge instructs the members that they may consider any issue as to authentication or identification of evidence in determining the weight, if any, to be given to the evidence.
(E) 
(i) Except as provided in clause (ii), hearsay evidence not otherwise admissible under the rules of evidence applicable in trial by general courts-martial may be admitted in a trial by military commission if the proponent of the evidence makes known to the adverse party, sufficiently in advance to provide the adverse party with a fair opportunity to meet the evidence, the intention of the proponent to offer the evidence, and the particulars of the evidence (including information on the general circumstances under which the evidence was obtained). The disclosure of evidence under the preceding sentence is subject to the requirements and limitations applicable to the disclosure of classified information in section 949j (c) of this title.
(ii) Hearsay evidence not otherwise admissible under the rules of evidence applicable in trial by general courts-martial shall not be admitted in a trial by military commission if the party opposing the admission of the evidence demonstrates that the evidence is unreliable or lacking in probative value.
(F) The military judge shall exclude any evidence the probative value of which is substantially outweighed
(i) by the danger of unfair prejudice, confusion of the issues, or misleading the commission; or
(ii) by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
(3)

(B) Failure of the accused to conform to the rules described in subparagraph (A) may result in a partial or total revocation by the military judge of the right of self-representation under paragraph (1)(D). In such case, the detailed defense counsel of the accused or an appropriately authorized civilian counsel shall perform the functions necessary for the defense.
(c) Delegation of Authority To Prescribe Regulations.— 
The Secretary of Defense may delegate the authority of the Secretary to prescribe regulations under this chapter.

(f) Protection of Classified Information.—
