(30 ILCS 415/8) (from Ch. 127, par. 708)
    Sec. 8.
    If the State fails to pay the principal of or interest on the Bonds as the same become due, a civil action to compel payment may be instituted in the Supreme Court of Illinois as a court of original jurisdiction by the holder or holders of the Bonds in respect of which such failure exists. Delivery of the summons and a copy of the complaint to the Attorney General or leaving them at his office in the capital with his assistant or clerk shall constitute good and sufficient service to give the Supreme Court of Illinois jurisdiction of the subject matter of such a suit of the State and its officer or officers named as defendants for the purpose of compelling such payment. Any case or cause of action concerning the validity of this Act relates to the revenue of the State of Illinois.
