N.D. Cent. Code § 29-10.1-21
Each grand jury impaneled within any county shall inquire into offenses against the criminal laws of the state alleged to have been committed within that county. The alleged offenses may be brought to the attention of the grand jury by the court or by any state's attorney or the state's attorney's designee. The state's attorney or the state's attorney's designee shall inform the grand jury of the alleged offense, the identity of the alleged offender, and the state's attorney or state's attorney's designee's action or recommendation. As to any offense committed while the grand jury is in session, the state's attorney or prosecutor may proceed with a preliminary examination or the filing of an information, as provided for by law, and prosecute the charge, and, under such conditions, the grand jury is not required to inquire into such offense. The presentment of an indictment against a person does not preclude the prosecution of such person for the same offense upon a criminal complaint or information previously filed with the court.
