Ill. Admin. Code tit. 44, § 500.1320
a) Determination that Solicitation or Award Violates Law
If the CPO finds that the solicitation or proposed award is in violation of statute or rule, the CPO may cancel the solicitation or proposed award, or make modifications to correct the violation, if such correction may be legally accomplished.
b) Determination that Contract Violates this Part
5) If, during the term of a contract, the CPO learns from an annual certification or otherwise determines that a subcontractor subject to this Part no longer qualifies to enter into State contracts, the CPO may declare the related contract void if it determines that voiding the contract is in the best interests of the State. However, the related contract shall not be declared void unless the contractor refuses to terminate the subcontract upon the State's request after a finding that the subcontractor no longer qualifies to enter into State contracts. [30 ILCS 500/50-60(e)]
c) Effect of Declaring a Contract Null and Void
In all cases in which a contract is voided, the OAG shall endeavor to return those supplies delivered under the contract that have not been used or distributed. No further payments shall be made under the contract.
