(45 ILCS 77/40) (from Ch. 114, par. 940)
    Sec. 40. Withdrawal from compact. This compact continues in force with respect to a participating state and remains binding upon the state until the state has given notice to each other participating state of the repeal of this Act. The withdrawal may not be construed to relieve a participating state from an obligation (in Illinois, an obligation that was expressly approved by the General Assembly) incurred before the end of the state's participation in the compact.
