If the commission fails to bring suit within ten days to restrain a violation as provided in R.S. 51:911.34, any person in interest adversely affected by the violation who has notified the commission in writing of the violation or threat thereof and has requested it to sue, may bring suit to prevent any or further violations, in the district court of any parish in which the commission could have brought suit. If the court holds 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 injunctions shall be issued as if the commission had at all times been the complaining party.
