PPI should win the lawsuit. "For sale" signs placed by businesses are considered a protected first amendment right based on the precedent of Linmark Associates, Inc v. Willingboro, 431 U.S. 85 (1977) (Jourdan, Hawkins, Abrams, & Winson-Geideman) Signs are considered a form of speech, a for sale sign is one of the best ways to communicate to consumers, and are therefore protected by the first amendment.

Is that right absolute? What about the City's interest in public safety?
