The ordinance amends Chapter 2-8 of the Municipal Code of Chicago by introducing a new Article V, which establishes a framework for City Council review of departmental rulemaking. It defines "rules" and outlines exceptions, emphasizing the importance of transparency and public participation in the rulemaking process. The article mandates that any proposed rule must be submitted to the City Council and relevant officials, along with a report detailing the rule's purpose, legal authority, and effective date. Aldermen can file resolutions to reject proposed rules based on various criteria, including economic impact and legal authority.

Additionally, the ordinance stipulates that no rule can take effect until after the next regular City Council meeting following its submission, unless a resolution rejecting the rule is passed. It also prohibits the re-promulgation of a substantially similar rule within 24 months of a rejection unless authorized by a new ordinance. Emergency rules can be enacted without following the standard process if necessary for public health or safety, but they are limited to a 90-day effectiveness unless a non-emergency rule is initiated. The ordinance will take effect 120 days after its passage.
