Article Four of the United States Constitution outlines the relationship between the various states, as well as the relationship between each state and the United States federal government. It also empowers Congress to admit new states and administer the territories and other federal lands.
Romer v. Evans, 517 U.S. 620 (1996), is a landmark United States Supreme Court case dealing with sexual orientation and state laws. It was the first Supreme Court case to address gay rights since Bowers v. Hardwick (1986), when the Court had held that laws criminalizing sodomy were constitutional.
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 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.
Santa Clara County v. Southern Pacific Railroad Company, 118 U.S. 394 (1886), is a corporate law case of the United States Supreme Court concerning taxation of railroad properties. The case is most notable for a headnote stating that the Equal Protection Clause of the Fourteenth Amendment grants constitutional protections to corporations.
Wheeling Steel Corp. v. Glander, 337 U.S. 562 (1949), was a United States Supreme Court case in which two out-of-state corporations objected to ad valorem taxes imposed upon accounts receivable derived from goods manufactured in Ohio, though these accounts were not used in conducting business in Ohio. The court ruled that the tax violated the Equal Protection Clause of the 14th Amendment.
Wallace v. Jaffree, 472 U.S. 38 (1985), was a United States Supreme Court case deciding on the issue of silent school prayer.
The Equal Protection Clause is part of the first section of the Fourteenth Amendment to the United States Constitution. The clause, which took effect in 1868, provides "nor shall any State ... deny to any person within its jurisdiction the equal protection of the laws". It mandates that individuals in similar situations be treated equally by the law.
Article IV, Section 1 of the United States Constitution, the Full Faith and Credit Clause, addresses the duties that states within the United States have to respect the "public acts, records, and judicial proceedings of every other state." According to the Supreme Court, there is a difference between the credit owed to laws as compared to the credit owed to judgments. Judges and lawyers agree on the meaning of the clause with respect to the recognition of judgments rendered by one state in the courts of another. Barring exceptional circumstances, one state must enforce a judgment by a court in another, unless that court lacked jurisdiction, even if the enforcing court otherwise disagrees with the result. At present, it is widely agreed that this Clause of the Constitution has a minimal impact on a court's choice of law decision provided that no state’s sovereignty is infringed, although this Clause of the Constitution was once interpreted to have greater impact.
In United States law, the Establishment Clause of the First Amendment to the United States Constitution, together with that Amendment's Free Exercise Clause, form the constitutional right of freedom of religion. The relevant constitutional text is:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof...
Harper v. Virginia State Board of Elections, 383 U.S. 663 (1966), was a case in which the U.S. Supreme Court found that Virginia's poll tax was unconstitutional under the equal protection clause of the 14th Amendment. In the late 19th and early 20th centuries, eleven southern states established poll taxes as part of their disenfranchisement of most blacks and many poor whites. The Twenty-fourth Amendment to the United States Constitution (1964) prohibited poll taxes in federal elections; five states continued to require poll taxes for voters in state elections. By this ruling, the Supreme Court banned the use of poll taxes in state elections.
Braunfeld v. Brown, 366 U.S. 599 (1961), was a case decided by the United States Supreme Court. In a 6–3 decision, the Court held that a Pennsylvania law forbidding the sale of various retail products on Sunday was not an unconstitutional interference with religion as described in the First Amendment to the United States Constitution.
Pace v. Alabama, 106 U.S. 583 (1883), was a case in which the United States Supreme Court affirmed that Alabama's anti-miscegenation statute was constitutional. This ruling was rejected by the Supreme Court in 1964 in McLaughlin v. Florida and in 1967 in Loving v. Virginia. Pace v. Alabama is possibly the first recorded interracial sex court case in America.
Personnel Administrator of Massachusetts v. Feeney, 442 U.S. 256 (1979), was a case heard by the Supreme Court of the United States. The decision upheld the constitutionality of a state law, giving hiring preference to veterans over nonveterans.
Allgeyer v. Louisiana, 165 U.S. 578 (1897), was a landmark United States Supreme Court case in which a unanimous court struck down a Louisiana statute for violating an individual's liberty of contract. It was the first case in which the Supreme Court interpreted the word liberty in the Due Process Clause of the Fourteenth Amendment to mean economic liberty. The decision marked the beginning of the Lochner era during which the Supreme Court struck many state regulations for infringing on an individual's right to contract. The Lochner era lasted 40 years and ended when West Coast Hotel Co. v. Parrish was decided in 1937.
Pike v. Bruce Church, Inc., 397 U.S. 137 (1970), was a case in which the Supreme Court of the United States held that power of states to pass laws interfering with interstate commerce is limited when the law poses an undue burden on businesses.
National Federation of Independent Business v. Sebelius, 567 U.S. 519 (2012), was a landmark United States Supreme Court decision in which the Court upheld Congress' power to enact most provisions of the Patient Protection and Affordable Care Act (ACA), commonly called Obamacare, and the Health Care and Education Reconciliation Act (HCERA), including a requirement for most Americans to pay a penalty for forgoing health insurance by 2014. The Acts represented a major set of changes to the American health care system that had been the subject of highly contentious debate, largely divided on political party lines.
O'Gorman & Young, Inc. v. Hartford Fire Ins. Co., 282 U.S. 251 (1931), was a case in which the United States Supreme Court held that a state statute limiting the commissions allowable by insurers against loss by fire to local agents will be deemed a valid exercise of the police power in the absence of facts showing it to be unreasonable.
Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015), is a 2015 U.S. Supreme Court decision which applied the dormant Commerce Clause doctrine to Maryland's personal income tax scheme and found that the failure to provide a full credit for income taxes paid to other states was unconstitutional.
Califano v. Goldfarb, 430 U.S. 199 (1977), was a decision by the United States Supreme Court, which held that the different treatment of men and women mandated by 42 U.S.C. § 402(f)(1)(D) constituted invidious discrimination against female wage earners by affording them less protection for their surviving spouses than is provided to male employees, and therefore violated the Due Process Clause of the Fifth Amendment to the United States Constitution. The case was brought by a widower who was denied survivor benefits on the grounds that he had not been receiving at least one-half support from his wife when she died. Justice Brennan delivered the opinion of the court, ruling unconstitutional the provision of the Social Security Act which set forth a gender-based distinction between widows and widowers, whereby Social Security Act survivors benefits were payable to a widower only if he was receiving at least half of his support from his late wife, while such benefits based on the earnings of a deceased husband were payable to his widow regardless of dependency. The Court found that this distinction deprived female wage earners of the same protection that a similarly situated male worker would have received, violating due process and equal protection.
