(30 ILCS 420/11) (from Ch. 127, par. 761)
    Sec. 11.
    If the State fails to pay the principal of or interest on any of 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 on which such default of payment exists. Delivery of a summons and a copy of the complaint to the Attorney General shall constitute sufficient service to give the Supreme Court of Illinois jurisdiction of the subject matter of such a suit and jurisdiction over the State and its officers named as defendants for the purpose of compelling such payment. Any case, controversy or cause of action concerning the validity of this Act relates to the revenue of the State of Illinois.
