Ferguson on May 18, 1896, ruling 7–1 that state-mandated racial segregation in public facilities did not violate the Constitution so long as the separate accommodations were equal.1Justia. Plessy v. Ferguson The ruling capped a case that had been engineered four years earlier as a deliberate test of Louisiana’s segregation law, and the “separate but equal” doctrine it produced governed American law until 1954.

The 1890 Law That Set the Case in Motion
Louisiana passed the Separate Car Act in 1890. The statute required every passenger railroad in the state to provide separate coaches for Black and white riders, barred passengers from sitting in a car designated for the other race, and demanded that the separate cars offer equal facilities.2Tulanian. Separate Car Act Passengers who refused to comply faced a $25 fine or 20 days in jail. Sixteen Black legislators in the state assembly opposed the bill, but they could not stop it.3National Archives. Plessy v. Ferguson (1896)
In 1891, a group of Black activists and professionals in New Orleans formed the Comité des Citoyens to challenge the law in court. They recruited Albion W. Tourgée, a white attorney from New York, and James C. Walker, a New Orleans lawyer, as counsel. The plan was to arrange a violation, get a defendant arrested, and push the case all the way to the Supreme Court.
June 7, 1892: Homer Plessy’s Arrest
On June 7, 1892, Homer Plessy bought a first-class ticket on the East Louisiana Railroad and took a seat in a coach reserved for white passengers. Under the racial classifications of the time, Plessy was one-eighth Black and could pass for white by appearance, which was part of the committee’s strategy: it exposed how arbitrary the law’s line-drawing really was.
A private detective hired by the committee identified Plessy and had him arrested when he refused to move. He was booked at the local jail and charged under the Separate Car Act, giving the committee the criminal case it needed.
The Louisiana Courts, 1892–1893
The case went to the Criminal District Court for the Parish of Orleans, where Judge John H. Ferguson presided.4Oyez. Plessy v. Ferguson Plessy’s attorneys argued that the Separate Car Act violated the Thirteenth Amendment by imposing a “badge of servitude” and violated the Fourteenth Amendment’s guarantee of equal protection.5Bill of Rights Institute. Plessy v. Ferguson Ferguson rejected both arguments, holding that Louisiana had the authority to regulate railroads within its borders. His name stayed attached to the case as it moved up.
Plessy’s team then petitioned the Louisiana Supreme Court to stop Ferguson from proceeding, arguing the underlying law was unconstitutional. The state justices reviewed the case as Ex parte Plessy.6vLex United States. Ex parte Plessy, 11 So. 948, 45 La.Ann. 80 Justice Charles Fenner wrote the opinion, filed on December 19, 1892, with rehearing denied on January 2, 1893.7Law Library of Louisiana. Litigation – Plessy v. Ferguson The court upheld the Separate Car Act. With state remedies exhausted, the case was bound for Washington.
May 18, 1896: The Supreme Court’s Ruling
The U.S. Supreme Court heard oral arguments on April 13, 1896, with Tourgée arguing for Plessy. The decision came down on May 18, 1896. Seven justices ruled against Plessy, one dissented, and Justice David Brewer did not participate.1Justia. Plessy v. Ferguson
Justice Henry Billings Brown wrote the majority opinion. He acknowledged that the Fourteenth Amendment was meant to establish “absolute equality for the races before the law” but drew a line between legal equality and social equality that, in his view, the amendment did not touch.4Oyez. Plessy v. Ferguson Requiring separate railroad cars, the majority held, did not stamp Black citizens as inferior; if Black passengers read degradation into the arrangement, that was their interpretation, not something the law imposed. Legislation, Brown wrote, could not overcome social prejudice, and separate-but-equal facilities satisfied the Constitution.8Bill of Rights Institute.

Justice Harlan’s Dissent
Justice John Marshall Harlan was the lone dissenter. He wrote that “our constitution is colorblind, and neither knows nor tolerates classes among citizens,” and called forced separation on a public highway “a badge of servitude wholly inconsistent with the civil freedom and the equality before the law established by the Constitution.”1Justia. Plessy v. Ferguson Harlan warned that the ruling would encourage further discriminatory laws and prove as damaging as the Dred Scott decision had been a generation earlier.
How Long the Decision Stood
The doctrine survived for 58 years. On May 17, 1954, the Supreme Court ruled unanimously in Brown v. Board of Education of Topeka that “separate but equal” had no place in public education. Chief Justice Earl Warren wrote that separate educational facilities are “inherently unequal” and violate the Equal Protection Clause of the Fourteenth Amendment.9U.S. Courts. History – Brown v. Board of Education Re-enactment Brown directly overturned the framework Plessy had established, though dismantling segregation in practice required years of further litigation and federal legislation, including the Civil Rights Act of 1964.10National Archives.

What Happened to Homer Plessy After 1896
Once the Supreme Court ruled against him, Plessy’s criminal case went back to the same New Orleans courtroom where it started. On January 11, 1897, he appeared in Criminal Court, pleaded guilty, and paid the $25 fine. He died in 1925.
On January 5, 2022, the governor of Louisiana posthumously pardoned Homer Plessy under a state law that expedites pardons for convictions rooted in statutes designed to enforce racial separation.11Library of Congress. The Posthumous Pardon of Homer Plessy
