"This ordinance was challenged in 2001 by the Interactive Digital Software Association (IDSA) as violative of freedom of expression as guaranteed by the first amendment.The IDSA cited the 7th Circuit case of "American Amusement Machine Association v. Kendrick" as precedent suggesting that video game content was a form of freedom of expression, however in 2002 the Eastern District Court of Missouri ultimately issued the controversial ruling that "video games are not a form of expression protected by the First Amendment" in "Interactive Digital Software Association v. St. Louis County".
