(a) No authority convening a general, special, or summary court-martial, nor any other commanding officer, may censure, reprimand, or admonish the court or any member, military judge, or counsel thereof, with respect to the findings or sentence adjudged by the court, or with respect to any other exercise of its or his functions in the conduct of the proceeding. No person subject to this chapter may attempt to coerce or, by any unauthorized means, influence the action of a court-martial or any other military tribunal or any member thereof, in reaching the findings or sentence in any case, or the action of any convening, approving, or reviewing authority with respect to his judicial acts. The foregoing provisions of the subsection shall not apply with respect to
(1) general instructional or informational courses in military justice if such courses are designed solely for the purpose of instructing members of a command in the substantive and procedural aspects of courts-martial, or
(2) to statements and instructions given in open court by the military judge, president of a special court-martial, or counsel.
(b) In the preparation of an effectiveness, fitness, or efficiency report, or any other report or document used in whole or in part for the purpose of determining whether a member of the armed forces is qualified to be advanced, in grade, or in determining the assignment or transfer of a member of the armed forces or in determining whether a member of the armed forces should be retained on active duty, no person subject to this chapter may, in preparing any such report
(1) consider or evaluate the performance of duty of any such member as a member of a court-martial, or
(2) give a less favorable rating or evaluation of any member of the armed forces because of the zeal with which such member, as counsel, represented any accused before a court-martial.
