In 1890, Louisiana enacted the Separate Car Act (Act 111), requiring railroads operating within the state to provide separate but equal railway accommodations for white and Black passengers. Conductors were authorized to assign passengers to cars on the basis of race, and refusal to comply was punishable by fine or imprisonment. The New Orleans Committee of Citizens, seeking to test the law's constitutionality, recruited Homer Plessy, a man who was seven-eighths white and one-eighth Black, to purchase a first-class ticket on the East Louisiana Railroad and sit in a whites-only car. On June 7, 1892, after Plessy announced his racial background to the conductor and refused to move to the car designated for Black passengers, he was arrested and charged under the Separate Car Act. In the Criminal District Court for the Parish of Orleans, Judge John H. Ferguson denied Plessy's constitutional challenge and upheld the statute. The Louisiana Supreme Court refused relief, and Plessy sought review in the U.S. Supreme Court, arguing that the statute violated the Thirteenth Amendment's prohibition on slavery and involuntary servitude and the Fourteenth Amendment's Equal Protection and Due Process Clauses.
Does a state law requiring racial segregation of passengers in railroad cars, under a regime of purportedly equal accommodations, violate the Thirteenth Amendment or the Equal Protection and Due Process Clauses of the Fourteenth Amendment?
State laws mandating racial segregation in public facilities do not violate the Thirteenth Amendment because segregation is not a badge of slavery within the meaning of that amendment, and they do not violate the Fourteenth Amendment so long as the separate facilities provided for each race are equal and the law is a reasonable exercise of the state's police power. The Fourteenth Amendment guarantees legal and political equality before the law, not enforced social commingling; any sense of inferiority arising from segregation is, under this doctrine, not attributable to the law if the facilities are equal.
No. The Supreme Court affirmed the Louisiana courts, holding that the Separate Car Act did not violate the Thirteenth Amendment and did not violate the Fourteenth Amendment because it required only the separation of races, not the unequal treatment of one race. Segregation was deemed constitutional under the separate but equal doctrine.
Writing for the Court, Justice Brown rejected Plessy's Thirteenth Amendment claim, reasoning that the amendment abolished slavery and involuntary servitude, not all distinctions based on race. He then turned to the Fourteenth Amendment, concluding that it was intended to establish legal equality of the races, particularly in civil and political rights, but not to abolish distinctions based upon color or to enforce social equality. The Court emphasized that segregation statutes did not necessarily imply the inferiority of either race and that any stigma felt by Black citizens was due to their own interpretation rather than the statute itself. Under this view, so long as the state provided accommodations that were equal in quality, separating the races was a permissible and reasonable exercise of the state's police power to promote public order, comfort, and the peace of the community. The majority analogized to existing practices such as segregated schools and interracial marriage prohibitions, suggesting that the Fourteenth Amendment had not historically been understood to bar such regulations. The Court also deferred significantly to the legislature's judgment about the reasonableness of the segregation law and refused to probe whether the facilities were truly equal in practice. Justice Harlan dissented. He argued that the Constitution is color-blind, neither knowing nor tolerating classes among citizens, and that the statute was a thinly veiled attempt to impose a caste system inconsistent with the equality guaranteed by the Fourteenth Amendment. Harlan critiqued the majority's reliance on formal equality and predicted that the decision would prove as pernicious as Dred Scott. His dissent emphasized that segregation laws are inherently unequal because their entire point is to denote Black citizens as inferior and to deny them the full rights of citizenship, thus violating both the letter and spirit of constitutional guarantees.
Plessy entrenched the separate but equal doctrine and legitimized Jim Crow segregation across transportation, education, public accommodations, and more for nearly six decades. It stands as a cautionary example of how judicial deference and a narrow reading of equality can enable systemic discrimination. The case was effectively repudiated by Brown v. Board of Education (1954), which held that segregation in public education is inherently unequal, and by subsequent civil rights legislation and jurisprudence dismantling state-mandated segregation. For law students, Plessy illuminates the historical development of equal protection doctrine, the interaction between constitutional text and social norms, and the long-term influence of powerful dissents in shaping constitutional meaning.
Plessy v. Ferguson institutionalized the separate but equal doctrine and marked a low point in the Supreme Court's protection of civil rights. Its narrow view of equality and deferential stance toward state police powers allowed pervasive racial segregation to flourish under constitutional cover. For modern students of constitutional law, Plessy is indispensable: it demonstrates how legal doctrines can entrench social hierarchies, highlights the power of dissents to shape future law, and frames the arc from Plessy's formal equality to Brown's recognition that segregation is inherently unequal. Understanding Plessy is key to understanding both the failures and the evolution of equal protection jurisprudence.
