The dissenting opinion in Plessy v. Ferguson was written by Justice John Marshall Harlan in 1896, and it rejected the Supreme Court’s approval of racial segregation with a single sentence that outlasted the majority: “Our Constitution is color-blind, and neither knows nor tolerates classes among citizens.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896) Harlan was the only justice to vote against upholding Louisiana’s Separate Car Act. Seven justices sided with the state; Justice David Brewer did not participate. For nearly sixty years the dissent sat unused. Then it became the intellectual spine of Brown v. Board of Education, and today it appears in Supreme Court opinions on both sides of the affirmative action debate.
What Harlan Actually Wrote
The famous passage is longer than the phrase people remember, and the extra sentences matter:
“The white race deems itself to be the dominant race in this country. And so it is in prestige, in achievements, in education, in wealth and in power. So, I doubt not, it will continue to be for all time if it remains true to its great heritage and holds fast to the principles of constitutional liberty. But in view of the Constitution, in the eye of the law, there is in this country no superior, dominant, ruling class of citizens. There is no caste here. Our Constitution is color-blind, and neither knows nor tolerates classes among citizens. In respect of civil rights, all citizens are equal before the law. The humblest is the peer of the most powerful.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896)
Harlan was not saying racial differences didn’t exist or that Black and white Americans lived on equal social footing. He conceded white social dominance as a fact and even predicted it would continue. His argument was narrower. Whatever society looks like, the law itself has no business sorting citizens by race. When a state does that, it builds a caste system, and caste is incompatible with a constitutional republic.
He refused to accept the majority’s framing that the Separate Car Act was a neutral regulation applying equally to both races. Forced separation of citizens on a public conveyance was, in his words, “a badge of servitude wholly inconsistent with the civil freedom and the equality before the law established by the Constitution.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896) Everyone knew the point of the law was to keep Black passengers away from white passengers. Pretending otherwise was, to Harlan, dishonest.
How Harlan Read the Reconstruction Amendments
The dissent rested on a broader reading of the amendments passed after the Civil War than the majority was willing to give them.
The Thirteenth Amendment
The Thirteenth Amendment abolished slavery and involuntary servitude.2Congress.gov. U.S. Constitution – Thirteenth Amendment The majority treated it as a narrow prohibition on physical bondage. Harlan read it to reach further. The amendment, he wrote, “not only struck down the institution of slavery as previously existing in the United States, but it prevents the imposition of any burdens or disabilities that constitute badges of slavery or servitude.”3Legal Information Institute. Plessy v. Ferguson Segregation, in that view, was one of those burdens. It marked Black citizens as subordinate in a way that echoed the status they had been freed from, even without chains.
The Fourteenth Amendment
The Fourteenth Amendment forbids any state from denying “any person within its jurisdiction the equal protection of the laws.”4Congress.gov. Fourteenth Amendment – Equal Protection and Other Rights Harlan argued the Reconstruction Amendments together “removed the race line from our governmental systems.” If states could still legislate on the basis of race after those amendments were ratified, the constitutional promise of equality meant nothing. He denied “that any legislative body or judicial tribunal may have regard to the race of citizens when the civil rights of those citizens are involved.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896) Separate but equal, on Harlan’s reading, was a contradiction that gutted the amendment’s purpose.
The “Thin Disguise” and Harlan’s Predictions
Harlan closed with predictions that turned out to be accurate. He called the majority’s talk of equality a fraud: “The thin disguise of ‘equal’ accommodations for passengers in railroad coaches will not mislead anyone, nor atone for the wrong this day done.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896) The separate facilities that followed the decision were never meaningfully equal, and Harlan understood in advance that they wouldn’t be. Laws written to separate people by race, in his view, exist to subordinate, not to accommodate.
He also warned that state-enforced segregation would deepen racial conflict rather than reduce it. “The destinies of the two races in this country are indissolubly linked together,” he wrote, “and the interests of both require that the common government of all shall not permit the seeds of race hate to be planted under the sanction of law.”1Justia. Plessy v. Ferguson, 163 U.S. 537 (1896) He compared the ruling to Dred Scott v. Sandford (1857), the pre-war decision denying citizenship to Black Americans. The Plessy majority, in his judgment, was making the same order of mistake: lending the Court’s authority to racial oppression.
The Limit of Harlan’s Vision
The dissent is not a clean statement of universal equality, and modern readers should know that before quoting it. To dramatize what he saw as the absurdity of the Separate Car Act, Harlan pointed out that Chinese immigrants, whom federal law barred from citizenship under the Chinese Exclusion Act, could legally sit in the same coach as white passengers. Black citizens, meanwhile, could be arrested for doing the same thing.3Legal Information Institute. Plessy v. Ferguson
The rhetorical setup accepted the premise of Asian exclusion. Harlan described the Chinese as “a race so different from our own that we do not permit those belonging to it to become citizens of the United States.” His argument was that Black Americans, being citizens, deserved better treatment than people the law had already decided to keep out. The claim for Black civil rights sat on top of anti-Asian prejudice. Harlan’s “color-blind” Constitution was, in practice, less blind than the phrase suggests.
Why the Dissent Won
Separate but equal governed American law for nearly six decades. The turn came in 1954. Thurgood Marshall, arguing Brown v. Board of Education for the NAACP, drew on Harlan’s dissent, and the color-blind passage was reportedly his favorite line from the opinion. A unanimous Court, through Chief Justice Earl Warren, held that “in the field of public education, the doctrine of ‘separate but equal’ has no place. Separate educational facilities are inherently unequal.”5Justia. Brown v. Board of Education of Topeka, 347 U.S. 483 (1954)
Brown did not adopt Harlan’s phrasing wholesale, but it reached the conclusion he had reached fifty-eight years earlier. The “thin disguise” he identified in 1896 was finally pulled off.
The Dissent in Today’s Equal Protection Fights
Harlan’s language remains active in Supreme Court opinions. In Students for Fair Admissions v. President and Fellows of Harvard College (2023), the Court struck down race-conscious admissions programs at Harvard and the University of North Carolina, holding they violated the Equal Protection Clause.6Justia. Students for Fair Admissions, Inc. v. President and Fellows of Harvard College Justice Clarence Thomas’s concurrence quoted the color-blind passage directly, tying it to what he called the “second founding” of the Reconstruction Amendments.
Harlan wrote the line to protect Black citizens from state-imposed disadvantage. In Students for Fair Admissions, the same words were used to bar universities from considering race in admissions programs meant to benefit historically disadvantaged applicants. Critics say applying a color-blind rule to an unequal society drains the doctrine of its original point. Defenders say Harlan’s principle means what it says, and the government may not sort people by race regardless of motive. That disagreement is now the central fault line in equal protection law, and Harlan’s 1896 dissent sits on both sides of it.
