Louisiana Code of Criminal Procedure Tit. V, Art. 209. When summons may be issued by magistrate

When a complaint is made of the commission of a misdemeanor and the requirements of Article 202 are met, the magistrate may issue a summons instead of a warrant of arrest, if he has reasonable ground to believe that the person against whom the complaint is made will appear upon a summons. In a case where a summons has been issued, a warrant of arrest may be issued later in its place.
