Mo. Rev. Stat. § 390.156
An action to recover a penalty or a forfeiture under this chapter or to enforce the powers of the division under this or any other law may be brought in any circuit court in this state in the name of the state of Missouri and shall be commenced and prosecuted to final judgment by the general counsel to the division. In any such action all penalties and forfeitures incurred up to the time of commencing the same may be sued for and recovered therein, and the commencement of an action to recover a penalty or forfeiture shall not be, or be held to be, a waiver of the right to recover any other penalty or forfeiture; if the defendant in such action shall prove that during any portion of the time for which it is sought to recover penalties or forfeitures for a violation of an order or decision of the division, the defendant was actually and in good faith prosecuting a suit to review such order or decision in the manner as provided in this chapter, the court shall remit the penalties or forfeitures incurred during the pendency of such proceeding. All moneys recovered as a penalty or forfeiture shall be paid to the public school fund of the state. Any such action may be compromised or discontinued on application of the division upon such terms as the court shall approve and order.
