Ill. Admin. Code tit. 44 § 8.25
No person shall have any right to a specific contract with the State unless that person has a contract that has been signed by an officer or employee of the purchasing agency with appropriate signature authority. The State shall be under no obligation to issue an award or execute a contract. [30 ILCS 500/1-25 ] No person who participates in a procurement action has any right to an award or subsequent contract. No notice of award can be issued and no contract can be executed without the written determination of a Procurement Officer. Neither receipt of a solicitation or other procurement documents nor submission of any response to a solicitation or other procurement request, solicited or otherwise, confers any right to receive an award or contract or contractually obligates the State in any manner.
