Separate but equal was a legal doctrine in United States constitutional law, according to which racial segregation did not necessarily violate the Fourteenth Amendment to the United States Constitution, which nominally guaranteed "equal protection" under the law to all people. Under the doctrine, as long as the facilities provided to each "race" were equal, state and local governments could require that services, facilities, public accommodations, housing, medical care, education, employment, and transportation be segregated by "race", which was already the case throughout the states of the former Confederacy. The phrase was derived from a Louisiana law of 1890, although the law actually used the phrase "equal but separate".
Adarand Constructors, Inc. v. Peña, 515 U.S. 200 (1995), was a landmark United States Supreme Court case which held that racial classifications, imposed by the federal government, must be analyzed under a standard of "strict scrutiny," the most stringent level of review which requires that racial classifications be narrowly tailored to further compelling governmental interests. Justice Sandra Day O'Connor wrote the majority opinion of the Court, which effectively overturned Metro Broadcasting, Inc. v. FCC, in which the Court had created a two tiered system for analyzing racial classifications. Adarand held the federal government to the same standards as the state and local governments through a process of "reverse incorporation," in which the 5th Amendment's Due Process Clause was held to bind the federal government to the same standards as state and local governments are bound under the 14th Amendment.
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.

Campbell v. Acuff-Rose Music, Inc., 510 U.S. 569 (1994), was a United States Supreme Court copyright law case that established that a commercial parody can qualify as fair use.

Illinois v. Caballes, 543 U.S. 405 (2005), is a decision by the Supreme Court of the United States in which the Court held that the use of a drug-sniffing police dog during a routine traffic stop does not violate the Fourth Amendment to the U.S. Constitution, even if the initial infraction is unrelated to drug offenses.

American Electric Power Company v. Connecticut, 564 U.S. 410 (2011), was a United States Supreme Court case in which the Court, in an 8–0 decision, held that corporations cannot be sued for greenhouse gas emissions (GHGs) under federal common law, primarily because the Clean Air Act (CAA) delegates the management of carbon dioxide and other GHG emissions to the Environmental Protection Agency (EPA). Brought to court in July 2004 in the Southern District of New York, this was the first global warming case based on a public nuisance claim.

Millbrook v. United States, 569 U.S. 50 (2013), is a decision by the Supreme Court of the United States that holds that the Federal Tort Claims Act (FTCA) waives the sovereign immunity of the United States for certain intentional torts committed by law enforcement officers. The unanimous opinion, delivered by Justice Clarence Thomas, holds that law enforcement "employment" duties are not limited to searches, seizures of evidence, or arrests, and, as such, the petitioner can sue. As this case revolved around sovereign immunity waivers and not the merits, the Court did not decide upon the merits of the lawsuits.

American Trucking Ass'ns, Inc. v. City of Los Angeles, 569 U.S. 641 (2013), was a case in which the Supreme Court of the United States held that certain regulations imposed by City of Los Angeles on trucking companies were preempted by federal law. In 2006 the Board of Harbor Commissioners for Los Angeles, California adopted an environmental protection plan that included an effort called Clean Truck Program (CTP). The stated goal of the program is to "reduce negative impacts that port [trucking] inflicts on the local community." The implementation of this program began in 2007 and required trucking companies to comply with various requirements relating to maintenance of trucks, employment of drivers, and trucking operations. The American Trucking Associations believed some of the regulations were in violation of the Federal Aviation Administration Authorization Act of 1994 (FAAAA) and filed suit. Litigation eventually made its way up to the Supreme Court of the United States, where the Court held that two of the requirements of the CTP were in violation of the FAAAA.
Sprint Communications, Inc. v. Jacobs, 571 U.S. 69 (2013), was a decision by the United States Supreme Court in which a unanimous Court held that federal court abstention under the Younger v.

Patel, 576 U.S. 409 (2015), was a United States Supreme Court case in which the Court held that a Los Angeles law, Municipal Code § 41.49, requiring hotel operators to retain records about guests for a ninety-day period is facially unconstitutional under the Fourth Amendment to the United States Constitution because it does not allow for pre-compliance review.

The plaintiffs, who were former slave laborers in the cocoa farms, brought their claim in U.S. district court under the ATS.
