Introduction to the Freedom of Information Act (FOIA)

Under the Illinois Freedom of Information Act (“FOIA”), 5 ILCS 140, certain records in possession of public agencies may be copied or inspected upon written request.  Public records under FOIA are “any records, reports, forms, writings, letters, memoranda, books, papers, maps, photographs, cards, tapes, recordings, electronic data processing records, electronic communications, recorded information, and all other documentary materials pertaining to the transaction of public business, regardless of physical form or characteristics, having been prepared by or for, or having been or being used by, received by, in the possession of or under the control of any public body.”  5 ILCS 140/2(c).



Some records and information, however, are exempt from disclosure via FOIA.  These types of records are generally described in Section 7 of FOIA, 5 ILCS 140/7.  Records may also be subject to confidentiality provisions imposed by other statutes or governing authority.
