1. If the director determines, based on substantial and competent evidence, that a corporation or insurer with a certificate of authority under the laws relating to insurance willfully has engaged in an act, practice, omission, or course of business constituting a level three, four, or five violation of the laws of this state relating to insurance in this chapter, chapter 354 and chapters 375 to 385, or been convicted of any felony or misdemeanor under any state or federal law, the director may, after hearing, issue an order suspending or revoking the certificate of authority.
