Existing law provides a district attorney with the discretion to file criminal charges against an individual. Existing law requires a preliminary examination to be conducted, as specified, before an information is filed. Upon completion of a preliminary hearing, existing law requires the district attorney to file an information against the defendant charging the defendant with either the offense or offenses named in the order of commitment or any offense or offenses shown by the evidence taken before the magistrate to have been committed. Under existing law, when an action is dismissed by a magistrate, as specified, the prosecutor may make a motion in the superior court within 15 days to compel the magistrate to reinstate the complaint or a portion of the complaint and to reinstate the custodial status of the defendant under the same terms and conditions as when the defendant last appeared before the magistrate.
