Illinois, similar to many states, defines "public records" as "all records…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." However, under this definition, CPD argued that emails exchanged by police officers on personal email accounts are not public records belonging to CPD.
Indeed, "[b]ecause the communication sought, if any exist, would have been prepared by or sent to individual officers and employees rather than the City, they are not communications 'prepared by or for' a public body. And because the communications would not be stored on a City server or account, they cannot be 'used by,' were not 'received by,' and are not 'in the possession of, or under the control of,' a public body. Thus, the requested communications, if any, do not fall within the FOIA's definition of a 'public record' and are not subject to production under the Act."
However, the Attorney General found that when a CPD police officer acts in an official capacity, he engages in public business as a member of a municipal police department, which is a public body as defined under FOIA. It further stated that the CPD's argument undermines the adage that public entities act through their employers, "by excluding from the definition of 'public records' communications sent or received by employees of a public body on personal devices or accounts, regardless of whether the communications pertain to the transaction of public business."
The Attorney General also took to task CPD's argument that the emails exchanged on officers' personal email accounts are not subject to FOIA requirements because CPD does not "possess or control" those records. It quoted from a recent federal Court of Appeals opinion which found that:
"The Supreme Court has described the function of FOIA as serving 'the citizens' right to be informed about what their government is up to.' If a department head can deprive the citizens of their right to know what his department is up to by the simple expedient of maintaining his departmental e-mails on an account in another domain, that purpose is hardly served. It would make as much sense to say that the department head could deprive requestors of hard-copy documents by leaving them in a file at his daughter's house and then claiming that they are under her control."
