The commissioner or a county attorney may institute a civil action in the name of the state in district court for an injunction prohibiting a violation of this section and for civil penalties not to exceed $1,000 for each violation of subdivision 2, 3, 4, 5a, 6, 7, or 7a. The court,
Upon proper proof that the defendant has engaged in a practice prohibited by this section, may enjoin the future commission of that practice and award civil penalties for violations of subdivision 2, 3, 4, 5a, 6, 7, or 7a. It is not a defense to an action that the state may have adequate remedies at law. Service of process must be as in any other civil suit, except that where a defendant in the action is a natural person or firm residing outside the state, or is a foreign corporation, service of process may also be made by personal service outside the state; in the manner provided by section 5.25; or as the court may direct. Process is valid if it satisfies the requirements of due process of law, whether or not the defendant is doing business in Minnesota regularly or habitually. Nothing in this subdivision limits the rights or remedies otherwise available to persons under common law or other statutes of this state.
