Brief Fact Summary. A city had an ordinance prohibiting picketing next to a school.
Synopsis of Rule of Law. Once a forum becomes public the government cannot prohibit speech there based on its content.
Issue. Is selective exclusion of picketing from a public place constitutional?
Held. No. The ordinance is a content-based prohibition and not a proper time, place, and manner restriction.
Discussion. The ordinance is defective because it discriminates based on the nature of the picket. It operates as a censor of what is publicly acceptable expression and what is not.
