Summary judgment in favor of defendant City of Norfolk on claims that the City's sign ordinance violated the plaintiffs' rights under the First Amendment and the Equal Protection Clause of the Fourteenth Amendment is affirmed, where: 1) by exempting flags or emblems of governmental or religious organizations from reasonable size restrictions, the City has not indicated any preference for a particular governmental or religious speaker or message; 2) by exempting works of art that are non-commercial in character, the City has not favored certain artistic messages over others; 3) therefore, the sign ordinance is a content-neutral restriction on speech that satisfies intermediate scrutiny; and 4) there is no merit in the plaintiffs' other constitutional challenges.
