An oldie but goody, Kitzmiller v. Dover Area School District
Tammy Kitzmiller, et al. v. Dover Area School District, et al. (400 F. Supp. 2d 707, Docket no. 4cv2688) was the first direct challenge brought in the United States federal courts testing a public school district policy that required the teaching of intelligent design. In October 2004 the Dover Area School District changed its biology teaching curriculum to require that intelligent design be presented as an alternative to evolution theory, and that Of Pandas and People was to be used as a reference book.
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.
All eight of the Dover school board members who were up for re-election on November 8, 2005 were defeated by a set of challengers who opposed the teaching of intelligent design in a science class. (The ninth member was not up for re-election.) The school board president subsequently stated that the board did not intend to appeal the ruling.
