Section 180

If the accused applies to the Court to issue any process for compelling the attendance of any witnesses (whether he has or has not been previously examined in the case) for the purpose of examination or cross-examination or the production of any document or other thing, the Court shall issue such process unless it considers that such application should be refused on the ground that it is made for the purpose of vexation, delay or for defeating the ends of justice. Such ground shall be recorded by it in writing.

The Court may, before summoning any witness on such application, require that his reasonable expenses incurred in attending for the purpose of the trial be deposited in Court, or may act under the provisions of section 383.

The Court may at any time adjourn the hearing of a case if satisfied that this course is in the interests of justice.
