(A) (1) The city shall, promptly, either comply with or deny a request for public records within five business days after its receipt of the request, unless the time for response is properly extended under § 32.47.
(2) Denials shall be in writing and in accordance with § 32.50. Failure to comply with a written request, extend the time for response, or deny a request within five business days after its receipt shall be considered a denial of the request. A public body that fails to respond to a request within the requisite periods in this section but thereafter provides the requester with copies of the requested public records may not impose a fee for those copies. A public body that fails to respond to a request received may not treat the request as unduly burdensome under § 32.48.
(5 ILCS 140/3(d))
(B) The time periods for compliance or denial of a request to inspect or copy records set out in 5 ILCS 140/3 shall not apply to requests for records made for a commercial purpose, requests by a recurrent requester, or voluminous requests. Such requests shall be subject to the provisions of 5 ILCS 140/3.1, 3.2, and 3.6.
