Although since 1976 the state Virginia law permitted school districts to implement 60 seconds of silence at the start of each school day, in 1985, the U.S. Supreme Court ruled that an Alabama "moment of silence or voluntary prayer" law was unconstitutional, in the case "Wallace v. Jaffree". In April 2000, a new law came into being; requiring all Virginian public school students to observe a moment of silence. Also, in 2005, a law was passed in Indiana requiring all public schools to give students a chance to say the pledge of allegiance and observe a moment of silence every day. In October 2007, Illinois enacted legislation to require public schools to provide students with a moment of silence at the start of the school day, a statute that is currently being challenged in Illinois state courts. According to the National Conference of State Legislatures, Alabama, Georgia, Louisiana, Massachusetts, Nevada, New Hampshire, Oklahoma, Rhode Island, South Carolina, Tennessee, Texas, and Virginia also require such moments of quiet in the classroom. In more than 20 other states, teachers are allowed to decide whether they want such a classroom time-out.
