On October 10, 2003, the U.S. Supreme Court declined to reinstate a challenge to commercial speech restrictions imposed by Chicago but then lifted after the challenge was filed. The decision was a setback for WLF, which had filed a petition with the Court in July, requesting that the Court review the case. Representing a group of Chicago advertisers, WLF argued that repeal of a challenged law while a lawsuit is pending is not valid grounds to dismiss the challenge, as the lower court did. WLF argued that to dismiss a suit as “moot” in such circumstances leaves a government free to re-impose the speech restrictions at any time. WLF argued that it is important for courts to enter injunctions against unconstitutional speech restrictions in order to ensure that such actions are not repeated. As is its usual custom, the Supreme Court provided no reasons for its decision not to hear the case.
