The Illinois Administrative Code (Ill. Adm. Code or IAC) is the official compilation of the administrative rules of Illinois state agencies published in the Illinois Register, and is maintained by the Illinois Secretary of State in cooperation with the Joint Committee on Administrative Rules.[1] The Illinois Administrative Code was last printed in 1996,[2] but is available online from the Illinois General Assembly's website.[3]
The Illinois Administrative Procedure Act [5 ILCS 100] governs the rulemaking process in Illinois.
