Epperson v. Arkansas, 393 U.S. 97 (1968), was a landmark United States Supreme Court case that invalidated an Arkansas statute prohibiting the teaching of human evolution in the public schools. The Court held that the First Amendment to the United States Constitution prohibits a state from requiring, in the words of the majority opinion, "that teaching and learning must be tailored to the principles or prohibitions of any religious sect or dogma." The Supreme Court declared the Arkansas statute unconstitutional because it violated the Establishment Clause of the First Amendment. After this decision, some jurisdictions passed laws that required the teaching of creation science alongside evolution when evolution was taught. These were also ruled unconstitutional by the Court in the 1987 case Edwards v. Aguillard.
Tinker v. Des Moines Independent Community School District, 393 U.S. 503 (1969), was a landmark decision by the United States Supreme Court that defined First Amendment rights of students in U.S. public schools. The Tinker test, also known as the "substantial disruption" test, is still used by courts today to determine whether a school's interest to prevent disruption infringes upon students' First Amendment rights.
The United States Reports are the official record of the Supreme Court of the United States. They include rulings, orders, case tables, in alphabetical order both by the name of the petitioner and by the name of the respondent, and other proceedings. United States Reports, once printed and bound, are the final version of court opinions and cannot be changed. Opinions of the court in each case are prepended with a headnote prepared by the Reporter of Decisions, and any concurring or dissenting opinions are published sequentially. The Court's Publication Office oversees the binding and publication of the volumes of United States Reports, although the actual printing, binding, and publication are performed by private firms under contract with the United States Government Publishing Office.
