117. (1) Whenever, in the course of a trial by a court- martial, it appears to the Court that the examination of a witness is necessary for the ends of justice, and that the attendance of such witness cannot be procured without an amount of delay, expense or inconvenience which, in the circumstances of the case, would be unreasonable, such Court may, if it thinks necessary, issue a commission in the manner specified in Chapter XL of the Code of Criminal Procedure, 1898, according as the witness resides in a place in or outside Bangladesh. (2) The Court may be adjourned for a specified time reasonably sufficient for the execution and return of the commission. (3) Such a commission shall be executed by the magistrate or officer to whom it is issued in the same manner as if it was issued in the trial of a warrant case under the Code of Criminal Procedure, 1898, or of any corresponding law in force at the place where the evidence is recorded; and shall be returned, together with the deposition of the witness examined thereunder to the Judge Advocate-General. (4) The Judge Advocate-General will forward the same to the court-martial who issued it or, if the said court-martial is in the meanwhile, dissolved to another court-martial convened for the trial of the accused in respect of the same charge and any deposition so taken shall be recorded in evidence and shall form part of the proceedings of the court.
