(a) Whenever it appears that a person is violating or threatening to violate any provision of this chapter, or any regulation or order of the commission, the commission shall bring suit against that person in the superior court of the judicial district where the violation occurs or is threatened, to restrain the person from continuing the violation or from carrying out the threat of violation. In the suit, the court shall have jurisdiction to grant to the commission, without bond or otherwise undertaking, such prohibitory and mandatory injunctions as the facts warrant.
(b) If the commission fails to bring suit to enjoin a violation or threatened violation within 10 days after receipt of written request to do so by a person who is or will be adversely affected by the violation, the person making the request may bring suit to restrain the violation or threatened violation in the court in which the commission may bring suit. If the court finds that injunctive relief should be granted, the commission shall be made a party and shall be substituted for the person who brought the suit, and the injunction shall be issued as if the commission had at all times been the plaintiff.
