Any person failing to comply with any subpoena issued by the Commission or pursuant to its authority is guilty of a Class 2 misdemeanor, and each day during which such violation shall continue shall be deemed a separate offense. In the event any person shall fail to comply with any regulation or order of the Commission, or obey any subpoena issued, or in the event of the refusal of any witness to testify to any matter concerning which he lawfully may be interrogated by the Commission or its representative, it shall be the duty of the Circuit Court where the principal offices of the Commission are located, upon application of the Commission, to compel obedience by attachment proceedings for contempt as in the case of disobedience of the requirements of a subpoena issued from the court, refusal to testify therein, or disobedience of an order or decree of the court. The proceedings herein authorized in the Circuit Court to compel obedience shall be in addition to the provisions of this section defining what shall constitute a misdemeanor and providing and prescribing the punishment therefor.
