RESEARCHING LEGISLATIVE HISTORY

Updated September 2017 by Legislative Reference Bureau staff

This page describes how to research the legislative history of a Public Act. Other aspects of legislative history, such as previous statutes on the same subject and court decisions to which the legislation was a response, are not covered by this page, although they may be revealed while researching legislative history. Interpretations of statutes by administrative agencies, the Attorney General, and the courts are also not covered. What weight a court may give to any particular element of legislative history in construing a statute is not covered. The intent of this page is merely to describe the documents and actions that make up legislative history and to give guidance on how and where to find the records relating to those documents and actions.

The cardinal rule of statutory construction is to determine and give effect to the legislature's intent. Sulser v. Country Mutual Ins. Co. , 147 Ill. 2d 548 (1992). A court should interpret a statute, where possible, according to the plain and ordinary meaning of the language used. Orlak v. Loyola University Health System , 228 Ill.2d 1 (2007). Intrinsic aids, such as canons of construction, may assist in the interpretation of a statute.

If the statutory language admits of more than one reasonable construction and is thus ambiguous, courts will consider extrinsic aids to construction. People v. Eppinger , 2013 IL 114121. Legislative history is an extrinsic aid to interpretation.

Legislative history includes legislative documents such as bills, adopted amendments, defeated amendments, and conference committee reports; committee testimony, records, debates, and actions; floor debates and actions; and the Governor's messages and actions.
