As I wrote in a November 2011 blog post, the U.S. District Court ruled that the ordinance was almost entirely unconstitutional under the First Amendment. But the 9th Circuit's brief order appears to suggest that the ordinance's constitutional problems were more pervasive than even the District Court had acknowledged.
Perhaps the City of San Francisco will finally take the First Amendment seriously and back down from forcing wireless merchants to issue misleading messages.
