N.D. Cent. Code § 18-01-10
The state fire marshal and the state fire marshal's deputies have the power in any county in the state to summon and compel the attendance of witnesses to testify in relation to any matter which is being investigated pursuant to the provisions of this chapter and to that end may administer an oath or affirmation to any person appearing as a witness before them. They may require the production of any pertinent books, papers, or documents, and a summons to appear before either of such officers must be served in the same manner and has the same effect as a subpoena in the district court. All witnesses shall receive the same compensation as is paid to witnesses in the district court, and such compensation must be paid out of the state fire marshal's arson hearing and building condemnation hearing fund upon a voucher signed by the state fire marshal or the deputy state fire marshal before whom any witnesses shall have attended, and approved by the office of the budget. At the close of an investigation to which any witnesses were subpoenaed, the officer conducting the investigation shall certify the attendance and mileage of such witnesses, which certificate must be filed in the office of the state fire marshal.
