(b)
(1) The penalty may be recovered by an action to be brought in the name of the State of Arkansas in the county in which the violation may occur.

(A) The department shall institute the action, and actions for the recovery of the penalties prescribed in this act, through the prosecuting attorney of the proper district.
(B) The prosecuting attorney shall be allowed a fee by the court not to exceed twenty-five percent (25%) of the amount collected.
(C) If any prosecuting attorney shall neglect for fifteen (15) days after notice to bring suit, the department may employ some other attorney at law to bring the suit who shall be allowed a fee therefor to be fixed by the court but not to exceed twenty-five percent (25%) of the amount collected. In such a case, the prosecuting attorney shall not interfere.
(3) No such suit shall be dismissed or compromised without the consent of the court and of the department.
