Illinois Freedom of Information Act: Public Records and Government Transparency

The Illinois Freedom of Information Act (FOIA), codified at 5 ILCS 140, establishes the legal framework governing public access to government records across state and local agencies. It defines which records are subject to disclosure, which are exempt, how agencies must respond to requests, and what enforcement mechanisms exist. The Act reflects a structural presumption that government records are public property, subject to specific statutory exceptions.

Definition and scope

The Illinois FOIA applies to all "public bodies" as defined under 5 ILCS 140/2, encompassing state agencies, units of local government, school districts, public universities, and legislative bodies at the state and local level. The Act covers records in any physical or electronic format — paper documents, emails, databases, audio recordings, and photographs all fall within its reach provided they are in the custody or control of a public body.

A "public record" is any document or data that was prepared by, used by, received by, or in the possession of a public body relating to the transaction of public business. The threshold is transactional — the record must relate to the conduct of government functions. Personal communications of public employees conducted on personal devices and unrelated to government business are generally outside this definition.

The statute does not apply to the federal government, federally chartered entities, or purely private organizations that receive public funding but do not otherwise qualify as public bodies under Illinois law. For a broader orientation to Illinois government structure and agencies, the Illinois Government Authority provides reference coverage across executive, legislative, and judicial branches.

Scope limitations: This page addresses the Illinois FOIA exclusively. Federal records requests are governed by the federal Freedom of Information Act (5 U.S.C. § 552), which is administered separately through federal agencies. The Illinois Open Meetings Act covers a related but distinct transparency mechanism governing access to public body deliberations.

How it works

The FOIA request process follows a structured procedural sequence:

  1. Submission — A requester submits a written request to the public body's designated FOIA officer, either by mail, fax, email, or in person. No justification for the request is required.
  2. Acknowledgment — The public body must respond within 5 business days of receiving the request (5 ILCS 140/3). A single 5-business-day extension is permitted with written notice and stated reason.
  3. Fulfillment or denial — The agency must either provide the records, redact exempt portions and provide the remainder, or issue a written denial citing specific statutory exemptions.
  4. Fee structure — The first 50 pages of black-and-white copies on standard paper are provided at no charge. Beyond that threshold, agencies may charge up to $0.15 per page (5 ILCS 140/6).
  5. Denial and appeal — A requester who receives a denial may file a Request for Review with the Illinois Public Access Counselor (PAC), an office within the Illinois Attorney General's office, within 60 calendar days of the denial.
  6. Judicial review — If the PAC declines to intervene or the requester is unsatisfied with the outcome, circuit court action is available.

The Public Access Counselor at the Illinois Attorney General's office has binding authority to issue binding opinions on FOIA disputes and can require disclosure or uphold denials.

Common scenarios

FOIA requests in Illinois most frequently arise in the following contexts:

Decision boundaries

The Act lists 23 categories of exempt records under 5 ILCS 140/7. The following comparison identifies the key distinctions between disclosable and exempt categories:

Category Generally Disclosable Generally Exempt
Government contracts Executed contracts, payment amounts Pre-decisional negotiation drafts
Personnel files Salary, title, employment dates Home address, personal financial data
Law enforcement Final incident reports, arrest records Ongoing investigation materials
Legal records Final judgments, settlement amounts Privileged attorney-client communications
Safety records Final inspection reports Security vulnerability assessments

The deliberative process privilege protects pre-decisional, deliberative communications — meaning internal agency drafts and recommendations that reflect policy formation rather than final agency action. This exemption is frequently invoked but narrowly construed by courts and the PAC.

Commercial requesters — defined as those seeking records for sale, resale, or direct commercial use — face a different fee schedule and may be denied expedited processing. Non-commercial requesters, including journalists and researchers, receive preferential treatment under the Act's tiered request classification system.
