  inquiry, of a person whose oral testimony cannot be  obtained,  may,  if
  otherwise admissible under the rules of evidence, be read in evidence by
  any  party  before a court-martial if the accused was a party before the

  consents to the introduction of such evidence.
    (b)  Such  testimony  may  be  read in evidence only by the defense in
  cases extending to the dismissal of an officer.
