Minn. R. Crim. P. 3.01
If the facts in the complaint and any supporting documents or supplemental sworn testimony establish probable cause to believe an offense has been committed and the defendant committed it, a summons or warrant must issue. A summons rather than a warrant must issue unless a substantial likelihood exists that the defendant will fail to respond to a summons, the defendant's location is not reasonably discoverable, or the defendant's arrest is necessary to prevent imminent harm to anyone. A warrant for the defendant's arrest must be issued to any person authorized by law to execute it.
The warrant or summons must be issued by a judge of the district court. If the offense is punishable by fine only, a court administrator may issue the summons when authorized by court order.
A summons must issue in lieu of a warrant if the offense is punishable by fine only in misdemeanor cases.
A judge must issue a summons whenever requested to do so by the prosecutor.
If a defendant fails to appear in response to a summons, a warrant must issue.
