Some of the most consequential shifts in American law began as a losing vote. A dissenting opinion is a judge’s written disagreement with the majority’s decision, and while it carries no binding authority, history offers striking dissenting opinion examples where the minority view eventually became the law. Justice Harlan in Plessy, Justice Holmes in Abrams, Justice Jackson in Korematsu, Justice Scalia in Morrison v. Olson, and Justice Ginsburg in Ledbetter each wrote dissents that later courts adopted, that Congress answered, or that reshaped how lawyers argue constitutional questions.
Justice Harlan in Plessy v. Ferguson (1896)
The majority in Plessy upheld a Louisiana law requiring racially segregated railway cars, establishing the “separate but equal” doctrine that governed American race relations for decades. Passengers who sat in the wrong car faced a fine of twenty-five dollars or up to twenty days in jail.1Cornell Law Institute. Plessy v Ferguson Justice John Marshall Harlan was the sole dissenter.
Harlan attacked segregation under both the Thirteenth and Fourteenth Amendments. He argued that the Thirteenth Amendment prohibited not just slavery itself but any “burdens or disabilities that constitute badges of slavery or servitude,” and that mandatory segregation was exactly such a burden. His most quoted line declared that “our constitution is color-blind, and neither knows nor tolerates classes among citizens.”1Cornell Law Institute. Plessy v Ferguson That language sat as a rejected minority view for fifty-eight years before the Court unanimously struck down school segregation in Brown v. Board of Education (1954), effectively adopting Harlan’s reasoning.
Justice Holmes in Abrams v. United States (1919)
The defendants in Abrams were convicted under the Espionage Act for distributing leaflets opposing American military intervention in the Russian Revolution. The majority upheld their convictions and twenty-year prison sentences.2Justia U.S. Supreme Court Center. Abrams v United States Justice Oliver Wendell Holmes, joined by Justice Brandeis, dissented.
Holmes argued that the government could only restrict speech when it posed an immediate, concrete danger, not merely because the ideas expressed were unpopular or offensive. His dissent introduced one of the most influential metaphors in American law: “the best test of truth is the power of the thought to get itself accepted in the competition of the market.”2Justia U.S. Supreme Court Center. Abrams v United States The “marketplace of ideas” concept became a foundation of modern First Amendment law, which now requires the government to clear a high bar before restricting speech.
Justice Jackson in Korematsu v. United States (1944)
The majority in Korematsu upheld the forced internment of Japanese Americans during World War II. Justice Robert Jackson dissented, warning that the Court had created something more dangerous than the military order itself. He wrote that a military order “is not apt to last longer than the military emergency,” but a Supreme Court opinion rationalizing that order “lies about like a loaded weapon, ready for the hand of any authority that can bring forward a plausible claim of an urgent need.”3Justia U.S. Supreme Court Center. Korematsu v United States
The “loaded weapon” metaphor became one of the most cited phrases in constitutional law. In 2018, the Supreme Court in Trump v. Hawaii formally overruled Korematsu, with the majority stating that the internment decision had been “gravely wrong the day it was decided.” Jackson’s dissent had waited seventy-four years to be vindicated.
Justice Scalia in Morrison v. Olson (1988)
Morrison v. Olson challenged the independent counsel provisions of the Ethics in Government Act, which allowed a special prosecutor to investigate executive branch officials outside the President’s direct control. The majority upheld the law 7-1. Justice Scalia was the lone dissenter.4Justia U.S. Supreme Court Center. Morrison v Olson
Scalia argued that the Constitution vests all executive power in the President, and that criminal prosecution is a core executive function that cannot be handed to an officer the President does not fully control. He accused the majority of replacing the Constitution’s structural separation of powers with a vague balancing test, writing that the Court simply “announces, with no analysis” that presidential control over prosecutions is not constitutionally required.4Justia U.S. Supreme Court Center. Morrison v Olson The independent counsel statute expired in 1999, and Scalia’s dissent became a foundational text for the unitary executive theory that continues to shape debates over presidential power.
Justice Ginsburg in Ledbetter v. Goodyear (2007)
Lilly Ledbetter discovered near retirement that she had been paid significantly less than her male colleagues for years. The majority held that her discrimination claim was untimely because she had not filed a complaint within 180 days of the first discriminatory pay decision, even though the effects of that decision appeared in every subsequent paycheck.5Justia U.S. Supreme Court Center. Ledbetter v Goodyear Tire and Rubber Co
Justice Ginsburg’s dissent argued that pay discrimination is fundamentally different from a discrete event like a firing or a denied promotion. Pay gaps develop in small increments, are often hidden from the employee, and compound over an entire career. She contended that each discriminatory paycheck should restart the filing clock, not just the original decision that set the lower pay.5Justia U.S. Supreme Court Center. Ledbetter v Goodyear Tire and Rubber Co Ginsburg took the unusual step of reading her dissent from the bench, a signal that she viewed the majority’s decision as an urgent call for legislative correction.
Congress answered. In 2009, President Obama signed the Lilly Ledbetter Fair Pay Act as the first piece of legislation of his presidency. The law established that each paycheck affected by a discriminatory compensation decision constitutes a new violation, resetting the filing deadline.6U.S. Equal Employment Opportunity Commission. Lilly Ledbetter Fair Pay Act of 2009 Few dissents have ever produced such a direct and rapid legislative response.
Why These Dissents Mattered
A dissenting opinion has no binding legal authority. Lower courts must follow the majority opinion under vertical stare decisis, which obligates every court to apply the holdings of the courts above it. A dissent, no matter how persuasive, is not a holding and creates no obligation for any court to follow it.
That is not the end of the story. Lawyers regularly cite dissents in their briefs to argue that existing precedent should be reconsidered, and a well-reasoned dissent gives litigants a ready-made roadmap for challenging the majority’s position. When the Supreme Court eventually overturns one of its own precedents, an earlier dissent frequently provides the intellectual foundation for the new majority. And when a dissent argues that a statute produces an unjust result, it can function as a direct invitation to Congress, which is exactly the path the Ledbetter dissent took.
Chief Justice Charles Evans Hughes once described a dissent as “an appeal to the brooding spirit of the law, to the intelligence of a future day.” The five examples above are what that description looks like in practice: opinions written by judges who lost the vote and won the argument, sometimes decades later.
