A court's written decision is called a judicial opinion (or simply an opinion). It is the document where the judge or panel of judges lays out the legal reasoning behind their ruling, states the facts they relied on, and announces the holding, the rule of law that decides the case.
What is the written statement containing the legal reasoning behind a court decision called?
It is called a judicial opinion. When a court rules on a case, this legal document will explain the reasoning for the decision: the facts the court relied on, the laws it applied, and why it reached that result. If you have ever answered the trivia question "what is a court's written decision called," the answer is the opinion.
On the Supreme Court, an opinion usually opens with a syllabus summarizing the case, then lays out the Court's analysis and its holding, the legal principle that decides the outcome. The Supreme Court's own website posts every opinion as a PDF, describing them as the documents relating to case argument that explain the judgment.
One opinion can carry several voices at once: the majority reasoning, a judge agreeing for different reasons, and a judge disagreeing entirely. Those variations are what the next section covers.
Why do courts write out their legal reasoning in opinions?
Three reasons: accountability, transparency, and appellate review.
Accountability comes first. A judge who has to explain why they ruled a certain way, in writing and in public, can't just rule on gut feel. The opinion is a record anyone can check, and a badly reasoned one invites criticism or appeal.
Transparency is next. The opinion tells the losing party exactly why they lost, and tells the public how the law was applied. When the answer to "this legal document will explain the reasoning for a court's decision" is the opinion itself, that document is what makes the ruling legible instead of arbitrary.
Appellate review depends on it. A higher court can only check a lower court's work if that work is written down. Judges review the reasoning, not just the result, and they reverse decisions where the reasoning fails even if the outcome looked fine.
That reasoning is also what later courts cite as precedent, which is why the written opinion, not the verdict, is the part of a case that lasts.
What are the different types of judicial opinions (majority, concurring, dissenting, plurality)?
A court's written decision usually contains several opinions, and each type carries different weight. The Cornell Wex legal dictionary breaks them into four main categories, distinguished by who wrote them and how many judges agreed.
Majority opinion
The majority opinion is the ruling signed onto by more than half the judges. It announces the decision and the legal reasoning behind it, and it is the only type that sets binding precedent for future cases.
Concurring opinion
A concurring opinion comes from a judge who agrees with the outcome but not the reasoning. It adds a separate argument and has no binding force on its own.
Dissenting opinion
A dissenting opinion is written by judges who disagree with the result. It changes nothing today, but dissents often shape the law decades later when a future court adopts their reasoning.
Plurality opinion
A plurality opinion is written when no single rationale wins a majority of judges. It states the result but carries the weakest precedential force, since later courts must figure out which part of the reasoning actually commanded the most votes.
| Opinion type | Who writes it | Binding force |
|---|---|---|
| Majority | More than half the judges | Sets binding precedent |
| Concurring | Judges agreeing with the result, not the reasoning | Persuasive only |
| Dissenting | Judges who disagree with the result | Persuasive only |
| Plurality | Largest group when no majority exists | Weakest; ambiguous reasoning |
If a quiz question asks which opinion explains the reasoning a future court must follow, the answer is the majority opinion. You can check any of these definitions without leaving your screen using the screenshot overlay at answerplz Docs.
How is a court opinion structured from syllabus to holding?
A published judicial opinion follows a fairly standard anatomy: caption, syllabus, statement of facts, the issue, the court's reasoning, the holding, and the disposition. Knowing the parts helps you skim efficiently, because you rarely need every piece.
Caption and syllabus
The caption identifies the court, the case name, the docket number, and the date of decision. The syllabus then follows: a short summary of the case and the main rulings, prepared by the court's reporter or the publisher. On Supreme Court opinions, the syllabus carries a warning that it is not part of the opinion itself, so you should never cite it as the court's language.
Facts, issue, and reasoning
The body of the opinion opens with the facts: what actually happened, who sued whom, and what the lower courts decided. Next comes the issue, the specific legal question the court must answer, often phrased as a single sentence. The reasoning section is the longest part. This is where "this legal document will explain the reasoning for" its decision: the court walks through the relevant rules, applies them to the facts, and responds to counterarguments, sometimes quoting earlier cases it considers binding or persuasive. Reading the reasoning is how you judge whether the conclusion actually follows, because a holding without its reasoning tells you the result but not the method, and the method is what you need if you want to predict how the court would handle a slightly different set of facts next time.
Holding and disposition
The holding is the court's answer to the issue: the rule that resolves the case and becomes the part later courts can apply. The disposition closes the opinion by stating what happens next, such as "affirmed," "reversed," or "remanded for further proceedings." Concurring and dissenting opinions, when present, appear after the majority and follow the same basic structure. If you want to test how quickly you can pull the holding out of a long opinion without switching windows, tools like answerplz (see how it compares with Jarvis) read the text on your screen and answer in context.
How do judicial opinions become precedent for future cases?
When a court issues an opinion, its holding — the legal rule the case actually decided — becomes precedent. Lower courts in the same jurisdiction must follow it when later cases raise the same legal question. This principle, called stare decisis, keeps the law consistent instead of letting every judge start from scratch.
Precedent works through a hierarchy. A federal circuit court's ruling binds the district courts beneath it, while only the Supreme Court's holdings bind courts nationwide. Courts distinguish binding holdings from dicta — side remarks in an opinion that carry persuasive weight but no obligation.
The US Courts website explains that federal court decisions set precedent for the cases that follow, which is how a single opinion shapes years of rulings.

Where can you read and cite Supreme Court opinions?
Free places to read opinions
The Supreme Court publishes every opinion on its own website, usually the same morning they are handed down. For older cases and easier navigation, Justia and CourtListener host full text going back to the 1700s, all free. The Legal Information Institute at Cornell is a good middle ground: clean text, syllabus, and headnotes for landmark cases.
How to cite an opinion
A basic citation follows the Bluebook format: case name, volume, reporter, page, and court plus year. For example: Brown v. Board of Education, 347 U.S. 483 (1954). "U.S." is the reporter for Supreme Court decisions, so that single string is enough for most schoolwork and blog posts. Cornell's LII keeps a readable guide to citation format if you need pin cites or subsequent history.
One honest note: reporters use abbreviations like "U.S." or "F.3d" that are not obvious at first, and most casual readers will never need them. If you just want to quote a holding, linking to the opinion on the Court's site is fine.
How do you get quick answers to legal terms like this without tab-switching?
If a quiz asks "this legal document will explain the reasoning for a court's decision," the answer is a judicial opinion. You can look that up the slow way: copy the question, switch to a chatbot tab, paste, wait, switch back. Or you press a global hotkey and answerplz reads your screen and answers in context, one click, no copy-paste. It works on trivia, articles, spreadsheets, and code errors the same way.
Honest limits: it answers what is visible on your screen, so a question buried in a long PDF may need you to scroll first. It is a screenshot Q&A overlay, not a legal research tool, so it will not pull case citations for you. There is a free tier with no card required, and paid plans sit in the $5-$20/mo band. If you already live in a chatbot and only hate the switching windows part, that is the trade it makes.
