Issue of summons for witness

If, either before or on the hearing of any complaint, it appears to the magistrate, on the statement of the complainant or of the defendant or otherwise, that any person is likely to give material evidence for the complainant or for the defendant, the magistrate may issue a summons to that person, requiring him to attend, at a time and place to be mentioned therein, before the court of the magistrate to give evidence respecting the case, and to produce to the court books, plans, papers, documents, articles and things which are in his possession, power or control, and likely to be material evidence on the hearing of the complaint.
