The United States Supreme Court rules in Plessy v. Ferguson that the "separate but equal" doctrine is constitutional.

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".The doctrine was confirmed in the Plessy v. Ferguson Supreme Court decision of 1896, which allowed state-sponsored segregation. Though segregation laws existed before that case, the decision emboldened segregation states during the Jim Crow era, which had commenced in 1876, and supplanted the Black Codes, which restricted the civil rights and civil liberties of African Americans during the Reconstruction Era.

In practice, the separate facilities provided to African Americans were rarely equal; usually they were not even close to equal, or they did not exist at all. For example, in the 1930 census, Black people were 42% of Florida's population. Yet according to the 193436 report of the Florida Superintendent of Public Instruction, the value of "white school property" in the state was $70,543,000, while the value of African-American school property was $4,900,000. The report says that "in a few south Florida counties and in most north Florida counties many Negro schools are housed in churches, shacks, and lodges, and have no toilets, water supply, desks, blackboards, etc. [See Station One School.] Counties use these schools as a means to get State funds and yet these counties invest little or nothing in them." At that time, high school education for African Americans was provided in only 28 of Florida's 67 counties. In 193940, the average salary of a white teacher in Florida was $1,148, whereas for a Black teacher it was $585.

During the era of segregation, the myth was that the races were separated but were provided equal facilities. No one believed it. Almost without exception, black students were given inferior buildings and instructional materials. Black educators were generally paid less than were their white counterparts and had more students in their classrooms.... In 1938, Pompano white schools collectively had one teacher for every 25 students, while the Pompano Colored School had one teacher for every 54 students. At the Hammondville School, the single teacher employed there had 67 students.

Because new research showed that segregating students by "race" was harmful to them, even if facilities were equal, "separate but equal" facilities were found to be unconstitutional in a series of Supreme Court decisions under Chief Justice Earl Warren, starting with Brown v. Board of Education of 1954. However, the subsequent overturning of segregation laws and practices was a long process that lasted through much of the 1950s, 1960s, and 1970s, involving federal legislation (especially the Civil Rights Act of 1964), and many court cases.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate and largely discretionary appellate jurisdiction over all federal and state court cases that involve a point of federal law, and original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The Court holds the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. However, it may act only within the context of a case in an area of law over which it has jurisdiction. The Court may decide cases having political overtones but has ruled that it does not have power to decide non-justiciable political questions.

Established by Article Three of the United States Constitution, the composition and procedures of the Supreme Court were initially established by the 1st Congress through the Judiciary Act of 1789. As later set by the Judiciary Act of 1869, the Court consists of the chief justice of the United States and eight associate justices. Each justice has lifetime tenure, meaning they remain on the Court until they die, retire, resign, or are removed from office. When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice. Each justice has a single vote in deciding the cases argued before the Court. When in majority, the chief justice decides who writes the opinion of the court; otherwise, the most senior justice in the majority assigns the task of writing the opinion.

The Court meets in the Supreme Court Building in Washington, D.C. Its law enforcement arm is the Supreme Court Police.
