Section 439: High Court Division's powers of revision
439.(1) In the case of any proceeding the record of which has been called for by itself or which has been reported for orders, or which otherwise comes to its knowledge, the High Court Division may, in its discretion, exercise any of the powers conferred on a Court of Appeal by sections 423, 426, 427 and 428 or on a Court by section 338, and may enhance the sentence; and, when the Judges composing the Court of Revision are equally divided in opinion, the case shall be disposed of in manner provided by section 429.
