65 ILCS 5/11-74.2-7

Within 30 days after the publication of a final commercial redevelopment plan, any person aggrieved by the action of the corporate authorities may seek a review of their decision and the redevelopment plan under the Administrative Review Law. The provisions of that Act and all amendments and modifications thereof and the rules adopted pursuant thereto shall apply to and govern all proceedings for the judicial review of the actions of the corporate authorities and the final commercial redevelopment plan.

If no action is initiated under the Administrative Review Law, or if the court sustains the corporate authorities and the final redevelopment plan as is, or as amended by the court, the corporate authorities may proceed to carry out the final commercial redevelopment plan.
