The court may:
A.Establish rules for its government and for the regulation of practice therein; appoint commissioners to assist the court in such manner as it directs and discharge them at will; and exercise such powers as are necessary to carry into effect the powers granted in this Section. Any Commissioner appointed shall be an attorney licensed to practice law in the State of Illinois. The rules established hereunder shall not be waived, and any extension of time authorized by such rules shall only be allowed on motion duly filed within the time limitation for which the extension is requested.B.Issue subpoenas through the Chief Justice or one of its judges or commissioners to require the attendance of witnesses for the purpose of testifying before it, or before any judge of the court, or before any notary public, or any of its commissioners, and to require the production of any books, records, papers or documents that may be material or relevant as evidence in any matter pending before it. In case any person refuses to comply with any subpoena issued in the name of the chief justice, or one of the judges or commissioners, attested by the clerk, with the seal of the court attached, and served upon the person named therein as a summons in a civil action is served, the circuit court of the proper county, on application of the party at whose instance the subpoena was issued, shall compel obedience by attachment proceedings, as for contempt, as in a case of a disobedience of the requirements of a subpoena from such court on a refusal to testify therein.
