Thayer v. Chiczewski, No. 10-1974 (7th Cir. 2012)
Annotate this Case
Chicago police officers arrested plaintiffs for disorderly conduct at a 2005 antiwar demonstration. The plaintiffs brought claims for First Amendment retaliation, Fourth Amendment false arrest, Fourteenth Amendment class-of-one equal protection violations, and state law malicious prosecution. They also brought facial challenges against Chicago’s disorderly conduct ordinance, as overbroad and unconstitutionally vague. The district court granted summary judgment. The Seventh Circuit affirmed on the basis of qualified immunity. The facial attack on the ordinance was rendered moot by an earlier decision, which partially invalidated the subsection on overbreadth and vagueness grounds. The court acknowledged that the plaintiffs’ arrests under a now-invalid ordinance may have affected their free speech rights, but that they did not bring an as-applied challenge to redress such an injury.
The court issued a subsequent related opinion or order on November 27, 2012.
