law: 81. Commissions for examination of witnesses.-
  (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.
  (2) The Chief Law Officer may then, if he thinks necessary, issue a commission to any Metropolitan Magistrate or Judicial Magistrate of the first class, within the local limits of whose jurisdiction such witness resides, to take the evidence of such witness.
  (3) The Magistrate to whom the commission is issued, or, if he is the Chief Metropolitan Magistrate or Chief Judicial Magistrate, he or such Metropolitan Magistrate or Judicial Magistrate of the first class as he appoints in this behalf shall proceed to the place where the witness is, or shall summon the witness before him and shall take down his evidence in the same manner, and may, for this purpose, exercise the same powers, as in the trials of warrant-cases under the Code of Criminal Procedure, 1973 (2 of 1974).
  (4) When the witness resides in any place outside India, the commission may be issued in the form and manner specified in sub section (3) of section 285 of the Code of Criminal Procedure, 1973 (2 of 1974).
