Section 18

Whenever 2 or more persons are charged with any offence under this Act, the Magistrate’s Court or District Court may require one or more of them to give evidence as a witness or witnesses for the prosecution.

Any such person who refuses to be sworn or affirmed or to answer any lawful question, shall be dealt with in the same way as witnesses so refusing may by law be dealt with by a Magistrate’s Court or District Court.

Every person so required to give evidence who, in the opinion of the court, makes true and full discovery of all things as to which he is lawfully examined, shall be entitled to receive a certificate of indemnity under the hand of the Magistrate or Judge, as the case may be, stating that he has made a true and full discovery of all things as to which he was examined, and such certificate shall be a bar to all legal proceedings against him in respect of such things as aforesaid.
