Kitzmiller v. Dover Area School District, 400 F. Supp. 2d 707 (M.D. Pa. 2005) was the first case brought in the United States federal courts testing a public school policy requiring the teaching of intelligent design (ID). The court found intelligent design to be not science. In October 2004, the Dover Area School District of York County, Pennsylvania, changed its biology teaching curriculum to require that intelligent design be presented as an alternative to evolution theory, and that Of Pandas and People, a textbook advocating intelligent design, was to be used as a reference book. The prominence of this textbook during the trial was such that the case is sometimes referred to as the Dover Panda Trial, a name which recalls the popular name of the Scopes Monkey Trial in Tennessee, 80 years earlier. The plaintiffs successfully argued that intelligent design is a form of creationism, and that the school board policy violated the Establishment Clause of the First Amendment to the United States Constitution. The judge's decision sparked considerable response from both supporters and critics.
