Mo. Rev. Stat. § 287.360

For any violation of the provisions of this chapter the director of the department of commerce and insurance may suspend or revoke the authority of any insurance carrier to do business in this state. If any insurance carrier fails or delays to pay any compensation finally determined to be due, the director shall hear the complaint, and if such failure is without reasonable excuse he may revoke or suspend the authority of such carrier to do business in this state, and in a proper case may apply for the appointment of a receiver for such carrier.
