A Supreme Court dissent is a written opinion by one or more justices who disagree with the majority’s decision in a case. It has no binding legal authority, so lower courts aren’t required to follow it, but it preserves an alternative reading of the law on the public record and sometimes becomes the foundation for a future ruling that overturns the very decision it opposed.
Where a Dissent Fits Among the Court’s Opinions
Every argued case produces at least one written opinion, and the Court publishes them together with a syllabus summarizing the outcome.1Supreme Court of the United States. Opinions Four labels do most of the work:
- The majority opinion is the Court’s official ruling, joined by at least five of the nine justices. It establishes binding precedent for every lower court in the country.
- A concurring opinion agrees with the outcome but gets there by different reasoning, or emphasizes a point the majority skipped past.
- A dissenting opinion disagrees with the outcome, the reasoning, or both. It creates no precedent.
- A per curiam opinion is unsigned and issued by the Court as a whole, often without oral argument.1Supreme Court of the United States. Opinions
The important distinction is authority. The majority opinion is the law. A concurrence adds color but doesn’t change the rule. A dissent, in the moment it’s issued, is a losing argument preserved in writing.
Two variations complicate the picture. When no single opinion attracts five votes, the result is a plurality opinion, which announces the Court’s judgment but lacks the full precedential weight of a true majority.2United States Courts. Glossary – U.S. v. Alvarez Future courts may cite the reasoning, but they aren’t bound by it. Justices can also file opinions that concur in part and dissent in part, agreeing with the majority on one question while rejecting its analysis of another in the same case.
Why Justices Write Dissents
A dissent is not just a protest. Justices use them strategically, and the first reason is accountability. A well-reasoned dissent forces the majority to address weaknesses in its own logic, and the mere threat of a strong dissent can sharpen or narrow a majority opinion during drafting, because the majority author knows the dissent will be published alongside it.
Dissents also speak to the future. A justice who believes the majority got it wrong can lay out an alternative framework in detail, creating a ready-made blueprint for lawyers and future courts when the issue returns. Some of the most consequential shifts in American constitutional law started as dissents that sat dormant for decades before being vindicated.
Dissents communicate directly with the public and with Congress, too. A justice who thinks a statute is being misread can use a dissent to invite the legislature to clarify or amend it. Dissents from denials of certiorari, where a justice publicly disagrees with the Court’s refusal to hear a case, serve a similar signaling function.1Supreme Court of the United States. Opinions
How a Dissent Gets Written
After oral arguments conclude, the justices meet in a private conference to discuss the case and take an initial vote, speaking in order of seniority starting with the Chief Justice. If the vote is not unanimous, the most senior justice on the losing side assigns a colleague to draft the dissent, though any justice in the minority is free to write a separate dissent as well.
What follows is an extended back-and-forth. Draft opinions circulate among all nine justices, and much of the real work happens in that internal exchange. A draft dissent might convince a wavering justice to switch sides, potentially flipping the outcome. The majority author, meanwhile, may revise reasoning in response to points raised in the circulating dissent. The process can take weeks or months, and final published opinions often look quite different from their first drafts.
Once positions are settled, the Court releases all opinions in the case simultaneously. The majority appears first, then any concurrences, then any dissents, ordered by seniority of the authoring justice.1Supreme Court of the United States. Opinions
Reading a Dissent From the Bench
On the day a decision is announced, only the majority opinion author normally reads a summary from the bench. Dissenting justices almost never read their opinions aloud. When one does, it’s a deliberate signal that the disagreement runs deep.
No formal rule governs when a justice may read a dissent from the bench. It happens when the spirit moves them, and not often. Justices Ruth Bader Ginsburg and Antonin Scalia both became known for the practice, using oral dissents to draw public and media attention to cases they believed the majority had gotten fundamentally wrong. A bench dissent is the judicial equivalent of raising your voice in a room where everyone speaks in measured tones.
Dissents That Later Became the Law
The most famous example is Justice John Marshall Harlan’s lone dissent in Plessy v. Ferguson (1896), where the Court upheld racial segregation under the “separate but equal” doctrine.3Legal Information Institute. Plessy v. Ferguson Harlan argued that the Constitution was colorblind and could not tolerate separation of citizens by race. Nearly sixty years later the Court adopted his reasoning when it struck down school segregation in Brown v. Board of Education (1954).
Justice Louis Brandeis’s dissent in Olmstead v. United States (1928) followed a similar arc. The majority held that wiretapping did not violate the Fourth Amendment because it involved no physical intrusion into a home. Brandeis argued that the Constitution protects a broader right to privacy that evolves with technology. Nearly four decades later, the Court embraced his reasoning in Katz v. United States (1967), holding that the Fourth Amendment protects people, not just physical spaces.
The turnaround can happen much faster. In Minersville School District v. Gobitis (1940), the Court ruled 8-1 that public schools could compel students to salute the flag. Justice Harlan Fiske Stone’s solitary dissent argued the rule violated religious liberty. Three years later, the Court reversed itself in West Virginia State Board of Education v. Barnette (1943), with six justices now siding with Stone. That reversal remains one of the fastest in Supreme Court history.
These cases aren’t anomalies. They reflect a recurring pattern: a dissent’s lack of binding authority is, in some ways, its greatest asset. A justice writing in dissent isn’t writing law, so they can be more candid, more provocative, and more forward-looking than a majority author who must carefully calibrate language that will govern real cases. That freedom produces some of the most memorable writing in American law, and it gives lawyers something to mine. When a shift in the Court’s composition reopens a previously settled issue, the losing side’s dissent from the original case becomes an instant roadmap for the new challenge.
How Often the Court Actually Divides
The frequency of dissent fluctuates term to term and depends heavily on the mix of cases the Court chooses to hear. In the 2024-2025 term, the Court issued 45 opinions after oral argument, and 34 were unanimous among the participating justices. Only nine decisions drew any dissenting opinion at all. That means roughly 80 percent of argued cases produced no dissent, though terms with more politically charged dockets have seen substantially higher rates of disagreement.
A justice can also dissent without writing a full opinion. A simple notation that “Justice X dissents” or “Justice X dissents from the denial of certiorari” appears regularly in the Court’s orders, registering disagreement without a detailed legal argument. These bare dissents are especially common in orders about whether the Court should take a case in the first place.
