Article One of the United States Constitution establishes the legislative branch of the federal government, the United States Congress. Under Article One, Congress is a bicameral legislature consisting of the House of Representatives and the Senate. Article One grants Congress various enumerated powers and the ability to pass laws "necessary and proper" to carry out those powers. Article One also establishes the procedures for passing a bill and places various limits on the powers of Congress and the states from abusing their powers.
The Dormant Commerce Clause, or Negative Commerce Clause, in American constitutional law, is a legal doctrine that courts in the United States have inferred from the Commerce Clause in Article I of the US Constitution. The primary focus of the doctrine is barring state protectionism. The Dormant Commerce Clause is used to prohibit state legislation that discriminates against, or unduly burdens, interstate or international commerce. Courts first determine whether a state regulation discriminates on its face against interstate commerce or whether it has the purpose or effect of discriminating against interstate commerce. If the statute is discriminatory, the state has the burden to justify both the local benefits flowing from the statute and to show the state has no other means of advancing the legitimate local purpose.
Planned Parenthood v. Casey, 505 U.S. 833 (1992), was a landmark decision of the Supreme Court of the United States in which the Court upheld the right to have an abortion as established by the "essential holding" of Roe v. Wade (1973) and issued as its "key judgment" the restoration of the undue burden standard when evaluating state-imposed restrictions on that right. Both the essential holding of Roe and the key judgment of Casey were overturned by the Supreme Court in 2022, with its landmark decision in Dobbs v. Jackson Women's Health Organization.
Griswold v. Connecticut, 381 U.S. 479 (1965), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Constitution of the United States protects the liberty of married couples to buy and use contraceptives without government restriction. The case involved a Connecticut "Comstock law" that prohibited any person from using "any drug, medicinal article or instrument for the purpose of preventing conception". The court held that the statute was unconstitutional, and that its effect was "to deny disadvantaged citizens ... access to medical assistance and up-to-date information in respect to proper methods of birth control." By a vote of 7–2, the Supreme Court invalidated the law on the grounds that it violated the "right to marital privacy", establishing the basis for the right to privacy with respect to intimate practices. This and other cases view the right to privacy as "protected from governmental intrusion".
Wabash, St. Louis & Pacific Railway Company v. Illinois, 118 U.S. 557 (1886), also known as the Wabash Case, was a Supreme Court decision that severely limited the rights of states to control or impede interstate commerce. It led to the creation of the Interstate Commerce Commission.
The Necessary and Proper Clause, also known as the Elastic Clause, is a clause in Article I, Section 8 of the United States Constitution:
The Congress shall have Power... To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof.
Edwards v. People of State of California, 314 U.S. 160 (1941), was a landmark United States Supreme Court case where a California law prohibiting the bringing of a non-resident "indigent person" into the state was struck down as unconstitutional.
The enumerated powers of the United States Congress are the powers granted to the federal government of the United States by the United States Constitution. Most of these powers are listed in Article I, Section 8.
Bray v. Alexandria Women's Health Clinic, 506 U.S. 263 (1993) is a United States Supreme Court case in which the court held that Section 1985(3) of The Civil Rights Act of 1871 does not provide a federal cause of action against persons obstructing access to abortion clinics. Alexandria Health Clinic, along with several other abortion clinics, sued to prevent Jayne Bray and other anti-abortion protesters from blocking the entrance to clinics in Washington D.C.
DaimlerChrysler Corp. v. Cuno, 547 U.S. 332 (2006), is a United States Supreme Court case involving the standing of taxpayers to challenge state tax laws in federal court. The Court unanimously ruled that state taxpayers did not have standing under Article III of the United States Constitution to challenge state tax or spending decisions simply by virtue of their status as taxpayers. Chief Justice John Roberts delivered the majority opinion, which was joined by all of the justices except for Ruth Bader Ginsburg, who concurred separately.
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."
Flint v. Stone Tracy Co., 220 U.S. 107 (1911), was a United States Supreme Court case in which a taxpayer challenged the validity of a federal income tax on corporations. The privilege of incorporation is a state function, and the challengers argued that only the states should tax corporations. The Court ruled that the privilege of operating in corporate form is valuable and justifies imposition of a federal income tax:
The Chase Court refers to the Supreme Court of the United States from 1864 to 1873, when Salmon P. Chase served as the sixth Chief Justice of the United States. Chase succeeded Roger Taney as Chief Justice after the latter's death. Appointed by President Abraham Lincoln, Chase served as Chief Justice until his death, at which point Morrison Waite was nominated and confirmed as his successor.
United States v. Wheeler, 254 U.S. 281 (1920), was an 8-to-1 landmark decision of the US Supreme Court that held that the Constitution alone does not grant the federal government the power to prosecute kidnappers, even if moving abductees across state lines on federally-regulated railroads at the behest of local law enforcement officials, and only the states have the authority to punish a private citizen's unlawful violation of another's freedom of movement. The case was a landmark interpretation of the Privileges and Immunities Clause of the Constitution, and contains a classic legal statement of the right to travel which continues to undergird American jurisprudence.
The Cherokee Tobacco Case, 78 U.S. 616 (1870), is a United States court case with implications relating to tribal sovereignty in the United States.
Smith v. Turner; Norris v. Boston, 48 U.S. 283 (1849), were two similar cases, argued together before the United States Supreme Court, which decided 5–4 that states do not have the right to impose a tax that is determined by the number of passengers of a designated category on board a ship and/or disembarking into the State. The cases are sometimes called the Passenger Case or Passenger Cases.
Kent v. Dulles, 357 U.S. 116 (1958), was a landmark decision of the U.S. Supreme Court on the right to travel and passport restrictions as they relate to First Amendment free speech rights. It was the first case in which the U.S. Supreme Court made a distinction between the constitutionally protected substantive due process freedom of movement and the right to travel abroad.
Article I, § 10, clause 2 of the United States Constitution, known as the Import-Export Clause, prevents the states, without the consent of Congress, from imposing tariffs on imports and exports above what is necessary for their inspection laws and secures for the federal government the revenues from all tariffs on imports and exports. Several nineteenth century Supreme Court cases applied this clause to duties and imposts on interstate imports and exports. In 1869, the United States Supreme Court ruled that the Import-Export Clause only applied to imports and exports with foreign nations and did not apply to imports and exports with other states, although this interpretation has been questioned by modern legal scholars.
Brown v. Maryland, 25 U.S. 419 (1827), was a significant United States Supreme Court case which interpreted the Import-Export and Commerce Clauses of the U.S. Constitution to prohibit discriminatory taxation by states against imported items after importation, rather than only at the time of importation. The state of Maryland passed a law requiring importers of foreign goods to obtain a license for selling their products. Brown was charged under this law and appealed. It was the first case in which the U.S. Supreme Court construed the Import-Export Clause. Chief Justice John Marshall delivered the opinion of the court, ruling that Maryland's statute violated the Import-Export and Commerce Clauses and the federal law was supreme. He alleged that the power of a state to tax goods did not apply if they remained in their "original package". A license tax on the importer was essentially the same as a tax on an import itself. Despite arguing the case for Maryland, future chief justice Roger Taney admitted that the case was correctly decided.
