The use of the title “registered interior designer”, as defined in Section 3, by any person not holding a valid and current registration under this Act is declared to be inimical to the public welfare, to constitute a public nuisance, and to cause irreparable harm to the public welfare. The Director, the Attorney General, the State‘s Attorney of any county in the State, or any person may maintain an action in the name of the People of the State of Illinois, and may apply for an injunction in the circuit court to enjoin any such person from engaging in the unlawful use of the title “registered interior designer”. Upon the filing of a verified petition, the court or any judge, if satisfied by affidavit or otherwise that such person has been engaged in such use without a valid and current registration, may issue a temporary injunction without notice or bond, enjoining the defendant from any such further use. Only the showing of the person’s lack of registration, by affidavit or otherwise, is necessary in order for a temporary injunction to issue. A copy of the verified complaint shall be served upon the defendant and the proceedings shall be conducted as in other civil cases except as modified by this Section. If it is established that the defendant has been or is engaged in any such unlawful use, the court or any judge may enter an order or judgment perpetually enjoining the defendant from further such use. In all proceedings under this Section, the court, in its discretion, may apportion the costs among the parties interested in the suit, including cost of filing the complaint, service of process, witness fees and expenses, court reporter charges and reasonable attorney’s fees. In case of violation of any injunction issued under this Section, the court or any judge may summarily try and punish the offender for contempt of court. Such injunction proceedings are in addition to, and not in lieu of, all penalties and other remedies provided in this Act.
