Issue of warrant for defendant in first instance

On a complaint in writing and upon oath being made before a magistrate for any summary conviction offence, the magistrate may, on good cause being shown to him for so doing, and on oath being made before him substantiating the matter of the complaint to his satisfaction, instead of issuing a summons, issue in the first instance a warrant to apprehend the person against whom the complaint has been made and to bring him before the court of the magistrate to answer the complaint, and to be further dealt with according to law.
