Barnes v. Glen Theatre, Inc., 501 U.S. 560 (1991), was a landmark decision of the U.S. Supreme Court concerning the First Amendment and the ability of the government to outlaw certain forms of expressive conduct. It ruled that the state has the constitutional authority to ban public nudity, even as part of expressive conduct such as dancing, because it furthers a substantial government interest in protecting the morality and order of society. This case is perhaps best summarized by a sentence in Justice Souter's concurring opinion, which is often paraphrased as "Nudity itself is not inherently expressive conduct."
