The First Amendment to the United States Constitution prevents the government from making laws that regulate an establishment of religion, or that prohibit the free exercise of religion, or abridge the freedom of speech, the freedom of the press, the freedom of assembly, or the right to petition the government for redress of grievances. It was adopted on December 15, 1791, as one of the ten amendments that constitute the Bill of Rights.
Lemon v. Kurtzman, 403 U.S. 602 (1971), was a case argued before the Supreme Court of the United States. The court ruled in an 8–0 decision that Pennsylvania's Nonpublic Elementary and Secondary Education Act from 1968 was unconstitutional and in an 8–1 decision that Rhode Island's 1969 Salary Supplement Act was unconstitutional, violating the Establishment Clause of the First Amendment. The act allowed the Superintendent of Public Schools to reimburse private schools for the salaries of teachers who taught in these private elementary schools from public textbooks and with public instructional materials. Lemon was a major precedent in federal and local courts until it was effectively overturned by Kennedy v. Bremerton School District in 2022.
Cohen v. California, 403 U.S. 15 (1971), was a landmark decision of the US Supreme Court holding that the First Amendment prevented the conviction of Paul Robert Cohen for the crime of disturbing the peace by wearing a jacket displaying "Fuck the Draft" in the public corridors of a California courthouse.
Citizens to Preserve Overton Park v. Volpe, 401 U.S. 402 (1971), is a landmark decision by the Supreme Court of the United States that established the basic legal framework for judicial review of the actions of administrative agencies. It substantially narrowed the Administrative Procedure Act's Section 701(a)(2) exception from judicial review. It also stands as a notable example of the power of litigation by grassroots citizen movements to block government action.
Cooper v. Aaron, 358 U.S. 1 (1958), was a landmark decision of the Supreme Court of the United States, which denied the school board of Little Rock, Arkansas, the right to delay racial desegregation for 30 months. On September 12, 1958, the Warren Court handed down a per curiam decision which held that the states are bound by the Court's decisions and must enforce them even if the states disagree with them, which asserted judicial supremacy established in Marbury v. Madison. The decision in this case upheld the rulings in Brown v. Board of Education and Brown II which held that the doctrine of separate but equal was unconstitutional.
Southern Pacific Company v. Arizona, 325 U.S. 761 (1945), was a United States Supreme Court case in which the Court held that the Arizona Train Limit Law of 1912, which prohibited passenger trains with more than fourteen cars and prohibited freight trains with more than seventy cars, placed an unconstitutional burden on interstate commerce. The Court held that the law imposed a burden far greater than necessary to achieve Arizona's legitimate interest in lowering the rate of train accidents. This case is part of the Court's so-called negative commerce clause jurisprudence.
Medellín v. Texas, 552 U.S. 491 (2008), was a decision of the United States Supreme Court that held that even when a treaty constitutes an international commitment, it is not binding domestic law unless it has been implemented by an act of the U.S. Congress or contains language expressing that it is "self-executing" upon ratification. The Court also ruled that decisions of the International Court of Justice are not binding domestic law and, like treaties, cannot be enforced by the president of the United States without authority from Congress or the U.S. Constitution.
Hines v. Davidowitz, 312 U.S. 52 (1941), is a case applying the law of conflict preemption. The United States Supreme Court held that a Pennsylvania state system of alien registration was superseded by a federal system because it was an "obstacle to the accomplishment" of its goals.
Commonwealth Edison Co. v. Montana, 453 U.S. 609 (1981), is a 6-to-3 ruling by the Supreme Court of the United States that held that a severance tax in Montana does not violate the Commerce Clause or the Supremacy Clause of the United States Constitution.
Coates v. City of Cincinnati, 402 U.S. 611 (1971), is a United States Supreme Court case in which the Court held that a local city ordinance that made it a criminal offense for three or more persons to assemble on a sidewalk and “annoy” any passersby was unconstitutionally vague. Dennis Coates participated in a protest along with four other unnamed students, all of whom were convicted of violating the city ordinance. Coates appealed to the Ohio Supreme Court, which upheld the conviction. However, this conviction was overturned in the divided United States Supreme Court decision. The Court found that the ordinance was unconstitutionally vague and violated the First Amendment freedom of assembly.
Gade v. National Solid Wastes Management Association, 505 U.S. 88 (1992), is a United States labor law case of the United States Supreme Court. The Court determined that federal Occupational Safety and Health Administration regulations preempted various Illinois provisions for licensing workers who handled hazardous waste materials.
Arizona v. New Mexico, 425 U.S. 794 (1976), is an opinion from the United States Supreme Court which denied a motion from the State of Arizona seeking authorization to file suit against the State of New Mexico by invoking the original jurisdiction of the court.
Arizona Public Service Co. v. Snead, 441 U.S. 141 (1979), was a United States Supreme Court case in which the Court held that a New Mexico tax on the generation of electricity was invalid under the Supremacy Clause of the United States Constitution. Snead was the director of the New Mexico Taxation and Revenue Department.
The Supremacy Clause of the Constitution of the United States establishes that the Constitution, federal laws made pursuant to it, and treaties made under its authority, constitute the "supreme Law of the Land", and thus take priority over any conflicting state laws. It provides that state courts are bound by, and state constitutions subordinate to, the supreme law. However, federal statutes and treaties must be within the parameters of the Constitution; that is, they must be pursuant to the federal government's enumerated powers, and not violate other constitutional limits on federal power, such as the Bill of Rights—of particular interest is the Tenth Amendment to the United States Constitution, which states that the federal government has only those powers delegated to it by the Constitution.
Goldstein v. California, 412 U.S. 546 (1973), was a United States Supreme Court case in which the high court ruled that California's state statutes criminalizing record piracy did not violate the Copyright Clause of the United States Constitution.
Metropolitan Life Insurance Co. v. Ward, 470 U.S. 869 (1985), was a case in which the Supreme Court of the United States held that a state cannot tax out-of-state insurance companies at a greater rate than domestic insurance companies under the Privileges and Immunities Clause of Article Four of the United States Constitution.
