The Tenth Amendment to the United States Constitution, a part of the Bill of Rights, was ratified on December 15, 1791. It expresses the principle of federalism, also known as states' rights, by stating that the federal government has only those powers delegated to it by the Constitution, and that all other powers not forbidden to the states by the Constitution are reserved to each state.
Adair v. United States, 208 U.S. 161 (1908), was a US labor law case of the United States Supreme Court which declared that bans on "yellow-dog" contracts were unconstitutional. The decision reaffirmed the doctrine of freedom of contract which was first recognized by the Court in Allgeyer v. Louisiana (1897). For this reason, Adair is often seen as defining what has come to be known as the Lochner era, a period in American legal history in which the Supreme Court tended to invalidate legislation aimed at regulating business.
The Commerce Clause describes an enumerated power listed in the United States Constitution. The clause states that the United States Congress shall have power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress. It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause, and the Indian Commerce Clause.
United States v. Morrison, 529 U.S. 598 (2000), is a U.S. Supreme Court decision that held that parts of the Violence Against Women Act of 1994 were unconstitutional because they exceeded the powers granted to the US Congress under the Commerce Clause and the Fourteenth Amendment's Equal Protection Clause. Along with United States v. Lopez (1995), it was part of a series of Rehnquist Court cases that limited Congress's powers under the Commerce Clause.
Hammer v. Dagenhart, 247 U.S. 251 (1918), was a United States Supreme Court decision in which the Court struck down a federal law regulating child labor. The decision was overruled by United States v. Darby Lumber Co. (1941).
National Labor Relations Board v Jones & Laughlin Steel Corporation, 301 U.S. 1 (1937), was a United States Supreme Court case that upheld the constitutionality of the National Labor Relations Act of 1935, also known as the Wagner Act. The case represented a major expansion in the Court's interpretation of Congress's power under the Commerce Clause and effectively spelled the end to the Court's striking down of New Deal economic legislation.
Seminole Tribe of Florida v. Florida, 517 U.S. 44 (1996), was a United States Supreme Court case which held that Article One of the U.S. Constitution did not give the United States Congress the power to abrogate the sovereign immunity of the states that is further protected under the Eleventh Amendment. Such abrogation is permitted where it is necessary to enforce the rights of citizens guaranteed under the Fourteenth Amendment as per Fitzpatrick v. Bitzer. The case also held that the doctrine of Ex parte Young, which allows state officials to be sued in their official capacity for prospective injunctive relief, was inapplicable under these circumstances, because any remedy was limited to the one that Congress had provided.
Champion v. Ames, 188 U.S. 321 (1903), was a decision by the United States Supreme Court which held that trafficking lottery tickets constituted interstate commerce that could be regulated by the U.S. Congress under the Commerce Clause.
United States v. Darby Lumber Co., 312 U.S. 100 (1941), was a case in which the United States Supreme Court upheld the Fair Labor Standards Act of 1938, holding that the U.S. Congress had the power under the Commerce Clause to regulate employment conditions. The unanimous decision of the Court in this case overturned Hammer v. Dagenhart, 247 U.S. 251 (1918), limited the application of Carter v. Carter Coal Company, 298 U.S. 238 (1936), and confirmed the underlying legality of minimum wages held in West Coast Hotel Co. v. Parrish, 300 U.S. 379 (1937).
Fullilove v. Klutznick, 448 U.S. 448 (1980), was a case in which the United States Supreme Court held that the U.S. Congress could constitutionally use its spending power to remedy past discrimination. The case arose as a suit against the enforcement of provisions in a 1977 spending bill that required 10% of federal funds going towards public works programs to go to minority-owned companies.
Houston East & West Texas Railway Co. v. United States, 234 U.S. 342 (1914), also known as the Shreveport Rate Case, was a decision of the United States Supreme Court expanding the power of the Commerce Clause of the Constitution of the United States. Justice Hughes's majority opinion stated that the federal government's power to regulate interstate commerce also allowed it to regulate purely intrastate commerce in cases where control of the former was not possible without control of the latter. Because the Supreme Court consolidated several related appeals, they are sometimes collectively known as the "Shreveport Rate Cases" although the Supreme Court issued only one ruling.
Nevada Department of Human Resources v. Hibbs, 538 U.S. 721 (2003), was a United States Supreme Court case which held that the Family and Medical Leave Act of 1993 was "narrowly targeted" at "sex-based overgeneralization" and was thus a "valid exercise of [congressional] power under Section 5 of the Fourteenth Amendment."
New York v. United States, 505 U.S. 144 (1992), was a decision of the United States Supreme Court. Justice Sandra Day O'Connor, writing for the majority, found that the federal government may not require states to “take title” to radioactive waste through the "Take Title" provision of the Low-Level Radioactive Waste Policy Amendments Act, which the Court found to exceeded Congress's power under the Commerce Clause. The Court permitted the federal government to induce shifts in state waste policy through other means.
Garcia v. San Antonio Metropolitan Transit Authority, 469 U.S. 528 (1985), is a landmark United States Supreme Court decision in which the Court held that the Congress has the power under the Commerce Clause of the Constitution to extend the Fair Labor Standards Act, which requires that employers provide minimum wage and overtime pay to their employees, to state and local governments. In this case, the Court overruled its previous decision in National League of Cities v. Usery, in which the Court had held that regulation of the activities of state and local governments "in areas of traditional governmental functions" would violate the Tenth Amendment to the United States Constitution.
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.
Gonzales v. Raich, 545 U.S. 1 (2005), was a decision by the U.S. Supreme Court ruling that under the Commerce Clause of the U.S. Constitution, Congress may criminalize the production and use of homegrown cannabis even if state law allows its use for medicinal purposes.
The constitutional law of the United States is the body of law governing the interpretation and implementation of the United States Constitution. The subject concerns the scope of power of the United States federal government compared to the individual states and the fundamental rights of individuals. The ultimate authority upon the interpretation of the Constitution and the constitutionality of statutes, state and federal, lies with the Supreme Court of the United States.
United States v. Alfonso D. Lopez, Jr., 514 U.S. 549 (1995), was a landmark case of the United States Supreme Court that struck down the Gun-Free School Zones Act of 1990 (GFSZA) due to its being outside of Congress's power to regulate interstate commerce. It was the first case since 1937 in which the Court held that Congress had exceeded its power under the Commerce Clause.
Freytag v. Commissioner of Internal Revenue, 501 U.S. 868 (1991), is a United States federal court case in which the Supreme Court of the United States decided the characteristics of inferior officers of the United States for the purposes of the Appointments Clause.
Gregory v. Ashcroft, 501 U.S. 452 (1991) was a U.S. Supreme Court case. It concerned a provision in the Missouri state constitution that required state judges to retire at the age of 70, and the court was asked to consider whether it conflicted with the 1967 federal Age Discrimination in Employment Act (ADEA) and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. The provision was upheld, with the case being one of several Supreme Court decisions supporting the principle that "ambiguous language will not be interpreted to intrude on areas of traditional state authority or important state governmental functions".
