(a) Chief Judge.—(1) The chief judge of the United States Court of Appeals for the Armed Forces shall be the judge of the court in regular active service who is senior in commission among the judges of the court who—

(A) have served for one or more years as judges of the court; and

(B) have not previously served as chief judge.

(2) In any case in which there is no judge of the court in regular active service who has served as a judge of the court for at least one year, the judge of the court in regular active service who is senior in commission and has not served previously as chief judge shall act as the chief judge.

(3) Except as provided in paragraph (4), a judge of the court shall serve as the chief judge under paragraph (1) for a term of five years. If no other judge is eligible under paragraph (1) to serve as chief judge upon the expiration of that term, the chief judge shall continue to serve as chief judge until another judge becomes eligible under that paragraph to serve as chief judge.

(4)

(A) The term of a chief judge shall be terminated before the end of five years if—

(i) the chief judge leaves regular active service as a judge of the court; or

(ii) the chief judge notifies the other judges of the court in writing that such judge desires to be relieved of his duties as chief judge.

(B) The effective date of a termination of the term under subparagraph (A) shall be the date on which the chief judge leaves regular active service or the date of the notification under subparagraph (A)(ii), as the case may be.

(5) If a chief judge is temporarily unable to perform his duties as a chief judge, the duties shall be performed by the judge of the court in active service who is present, able and qualified to act, and is next in precedence.

(b) Precedence of Judges.—The chief judge of the court shall have precedence and preside at any session that he attends. The other judges shall have precedence and preside according to the seniority of their original commissions. Judges whose commissions bear the same date shall have precedence according to seniority in age.

(c) Status of Certain Positions.—(1) Attorney positions of employment under the Court of Appeals for the Armed Forces are excepted from the competitive service. A position of employment under the court that is provided primarily for the service of one judge of the court, reports directly to the judge, and is a position of a confidential character is excepted from the competitive service. Appointments to positions referred to in the preceding sentences shall be made by the court, without the concurrence of any other officer or employee of the executive branch, in the same manner as appointments are made to other executive branch positions of a confidential or policy-determining character for which it is not practicable to examine or to hold a competitive examination. Such positions shall not be counted as positions of that character for purposes of any limitation on the number of positions of that character provided in law.

(2) In making appointments to the positions described in paragraph (1), preference shall be given, among equally qualified persons, to persons who are preference eligibles (as defined in section 2108(3) of title 5).
