Lore & Background

Plessy was arrested by a private detective hired by the Comité des Citoyens, a civil rights group that orchestrated the test case. At trial, Judge John Howard Ferguson denied Plessy's motion to dismiss the charges, and the Louisiana Supreme Court upheld that ruling.

Reader's Guide

The U.S. Supreme Court's 7–1 decision in Plessy v. Ferguson held that the Louisiana law did not violate the Fourteenth Amendment, reasoning that the amendment established legal equality but did not eliminate all distinctions based on color. The Court deferred to state legislatures' police power to regulate health, safety, and morals. Justice John Marshall Harlan dissented, arguing the Constitution is color-blind. Although never explicitly overruled, the decision was severely weakened beginning with Brown v.

Frequently Asked Questions

What was the vote and who wrote the majority opinion?

The Court ruled 7–1 to uphold Louisiana's segregation law. Justice Henry Billings Brown penned the majority opinion, reasoning that physically separate facilities could satisfy the equal-protection requirement even if they carried a social stigma of inferiority.

Who dissented in Plessy v. Ferguson and why is that dissent famous?

Justice John Marshall Harlan was the lone dissenter, arguing that the Constitution is color-blind and that the majority's logic would brand Black citizens as a subordinate caste. His lone voice is frequently called one of the most powerful dissents in the Court's history.

Why do legal scholars rank Plessy v. Ferguson among the Court's worst decisions?

The ruling transformed racial segregation from a local social custom into a constitutionally sanctioned legal regime, entrenching disenfranchisement and inequality for nearly six decades. It is widely cited as the decision that made Jim Crow not merely a cultural norm but a state-enforced legal structure.
