Whenever it appears to the commissioner that any insurer or any director, officer, employee, or agent thereof has committed or is about to commit a violation of this chapter or any rule, regulation, or order issued by the commissioner hereunder, the commissioner may apply to the district court of the county in which the principal office of the insurer is located or if such insurer has no such office in this state then to the district court of Polk county for an order enjoining such insurer or such director, officer, employee, or agent thereof from violating or continuing to violate this chapter or any such rule, regulation, or order, and for such other equitable relief as the nature of the case and the interests of the insurer’s policyholders, creditors, and shareholders or the public may require.

 No security which is the subject of any agreement or arrangement regarding acquisition, or which is acquired or to be acquired, in contravention of the provisions of this chapter or of any rule, regulation, or order issued by the commissioner hereunder may be voted at any shareholders’ meeting, or may be counted for quorum purposes, and any action of shareholders requiring the affirmative vote of a percentage of shares may be taken as though such securities were not issued and outstanding; but no action taken at any such meeting shall be invalidated by the voting of such securities, unless the action would materially affect control of the insurer or unless the district court has so ordered. If any insurer or the commissioner has reason to believe that any security of the insurer has been or is about to be acquired in contravention of the provisions of this chapter or of any rule, regulation, or order issued by the commissioner hereunder the insurer or the commissioner may apply to the district court of Polk county or to the district court for the county in which the insurer has its principal place of business to enjoin any offer, request, invitation, agreement, or acquisition made in contravention of section 521A.3 or any rule, regulation, or order issued by the commissioner thereunder to enjoin the voting of any security so acquired, to void any vote of such security already cast at any meeting of shareholders, and for such other equitable relief as the nature of the case and the interests of the insurer’s policyholders, creditors, and shareholders or the public may require.

 In any case where a person has acquired or is proposing to acquire any voting securities in violation of this chapter or any rule, regulation, or order issued by the commissioner hereunder, the district court of Polk county or the district court for the county in which the insurer has its principal place of business may, on such notice as the court deems appropriate, upon the application of the insurer or the commissioner seize or sequester any voting securities of the insurer owned directly or indirectly by such person, and issue such orders with respect thereto as may be appropriate to effectuate the provisions of this chapter. Notwithstanding any other provisions of law, for the purposes of this chapter the situs of the ownership of the securities of domestic insurers shall be deemed to be in this state.
