Any person who believes a violation of this part 5 has occurred may file a written complaint no later than sixty days after the date of the violation with the secretary of state. If the secretary of state determines, after a hearing, that the violation has occurred, he or she shall so notify the attorney general, who may institute a civil action for relief, including a permanent or temporary injunction, a restraining order, or any other appropriate order, in the district court. Upon a proper showing that such person has engaged or is about to engage in any prohibited acts or practices, a permanent or temporary injunction, restraining order, or other order shall be granted without bond by the court. If, within one hundred twenty days after a complaint is filed with the secretary of state, no civil action for relief is instituted by the attorney general, the complainant shall have a private right of action based on an alleged violation of this part 5 and may institute a civil action in district court for any appropriate remedy. Any such action shall be filed within one year from the date of the alleged violation.
