Section 117, THE CRIMINAL PROCEDURE ACTS, 1965

If the accused states that he has witnesses to call, but that they are not present in Court, and the Court is satisfiedthat the absence of the witnesses is not due to any fault of the accused, and that there is a likelihood that they could, if present, give material evidence on his behalf, the Court may adjourn the investigation and issue process, or take other steps, to compel the attendance of such witnesses.
