(1)Whenever, in the course of a trial by a Coast Guard Court, 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 address the Chief Law Officer in order that a commission to take the evidence of such witness may be issued.
