The Complaint

(a) General. The complaint is a written statement of the essential facts constituting the elements of the offense charged. The complaint must be sworn to and subscribed before an officer authorized by law to administer oaths within this state, or must contain a written declaration that it is made and subscribed under penalty of perjury, and be presented to a magistrate. The complaint may be presented as provided in Rule 4.1 . (b) Magistrate Review. The magistrate may examine on oath the complainant and other witnesses and receive any affidavit filed with the complaint. If the magistrate examines the complainant or other witnesses on oath, the magistrate shall cause their statements to be reduced to writing and subscribed by the persons making them or to be recorded. (c) Amendment. The magistrate may permit a complaint to be amended at any time before a finding or verdict if no additional or different offense is charged and if substantial rights of the defendant are not prejudiced. If the prosecuting attorney chooses not to pursue a charge contained in the initial complaint, a dismissal of that charge must be stated on the amended complaint.
