Chapman v. City of Chicago Fire Department

Trial court granted plaintiff’s Freedom of Information Act request seeking disclosure of an “index of tables and columns within each table” of the Citation Administration and Adjudication System (CANVAS). Defendant appealed, arguing the requested information was exempt from disclosure under section 7(1)(o) of the Act, which excludes certain technical information when its disclosure would jeopardize the security of the system or its materials. The appellate court affirmed finding the trial court’s ruling was not against the manifest weight of the evidence where there was testimony that public disclosure of the information would not create a vulnerability in the system.
