At any time after the service of charges which have been referred for trial to a court-martial composed of a military judge and members, the military judge may, subject to SECTION 25-1-2685, call the court into session without the presence of the members for the purpose of: (1) hearing and determining motions raising defenses or objections which are capable of determination without trial of the issues raised by a plea of not guilty; (2) hearing and ruling upon any matter which may be ruled upon by the military judge under this code, whether or not the matter is appropriate for later consideration or decision by the members of the court; (3) unless prohibited by regulations of the Governor, holding the arraignment and receiving the pleas of the accused; (4) performing any other procedural function which may be performed by the military judge under this code under rules prescribed pursuant to SECTION 25-1-2690 and which does not require the presence of the members of the court. These proceedings must be conducted in the presence of the accused, the defense counsel, and the trial counsel and must be made a part of the record.
