Is a Pre-Sale Home Inspection Requirement Constitutional?

Mann v. Calumet City, 09-1681 (7th Cir. Dec. 7, 2009) (here).  I haven't read it, but it seems interesting.  A quick skim reveals, "frivolous," "criminal contempt," and "Posner."  So, yeah, I'll definitely be checking this one out during tomorrow's coffee break.
