Rule 100. Criminal and quasi-criminal causes

(a) Issuance of warrant or summons. In criminal or quasi-criminal causes, if it appears upon the complaint that there is probable cause to believe that an offense has been committed and that defendant has committed it, a warrant or summons shall issue to the marshal, or to a police officer or other person designated by the court.

(b) Form of warrant. The warrant shall be signed by the judge or, if authorized by him, attested in his name and signed by the clerk or deputy clerk of the court, and shall contain the name of the defendant or, if his name is unknown, any name or description by which he can be identified with reasonable certainty, and shall describe the offense charged in the complaint. It shall command that the defendant be arrested and brought before the court issuing the warrant.

(c) Form of summons. In criminal or quasi-criminal causes, the summons shall be in the same form as the warrant, except that it shall summon the defendant to appear before the court at a stated time and place.

(d) Execution or service: return. In criminal or quasi-criminal causes, the provisions of Rule 123 shall apply.--Amended May 27, 1965.
