An unpublished opinion is a court decision the issuing court has designated as non-precedential, meaning it resolves the dispute between the parties but is not intended to bind future cases. Unpublished opinions are not sealed or hidden — you can find nearly all of them on PACER, court websites, and databases like Westlaw and LexisNexis. More than 85 percent of federal appellate decisions carry this designation, so understanding what the label does and doesn’t do matters for anyone researching case law or preparing a filing.
What the Label Actually Means
“Unpublished” is misleading shorthand. The decision exists in writing, is publicly available, and resolves a real case. What it lacks is inclusion in the official reporters — the United States Reports for the Supreme Court and the Federal Reporter series for lower federal courts.1Supreme Court of the United States. U.S. Reports Exclusion from those volumes signals the court’s intent that the ruling not guide future disputes.
Different courts use different labels for the same idea. You’ll see “memorandum opinion,” “summary order,” “non-precedential disposition,” and simply “unpublished.” A memorandum opinion typically contains at least some reasoning applying settled law to the facts. A summary disposition may be as short as a one-line order affirming the lower court. Both lack precedential force.
Why Courts Designate Opinions This Way
Most appeals don’t change the law. They apply well-settled rules to a particular set of facts. A routine sentencing challenge decided under clearly established guidelines, for example, adds nothing new to the body of law, and publishing it would clutter the reporters without helping anyone.
Publication is generally reserved for opinions that establish a new legal rule, modify or clarify an existing principle, resolve a split among prior decisions, or address a question of significant public interest. The Fifth Circuit’s local rules put it bluntly: publishing opinions with no precedential value “imposes needless expense on the public and burdens on the legal profession.”
Volume drives the practice. Federal appellate courts decide tens of thousands of cases a year. Treating every routine affirmance like a landmark ruling would make the body of binding law unmanageable to research.
Binding Precedent Versus Persuasive Authority
Under stare decisis, a published opinion from a higher court creates a mandatory obligation for lower courts in the same jurisdiction to follow it. That vertical hierarchy is what makes an appellate ruling “the law” rather than one judge’s reasoning.
An unpublished opinion sits outside that hierarchy. No lower court is required to follow it, and no litigant can demand that a judge treat it as controlling. What an unpublished opinion can offer is persuasive authority — a court may find the reasoning useful even though it isn’t bound by the result.
Persuasive value is highest where the same factual patterns repeat across many cases. If you’re arguing a disability benefits appeal and the published cases don’t address your exact situation, three unpublished opinions from the same court ruling favorably on similar facts can meaningfully strengthen your argument. The judge isn’t obligated to follow them, but they show how the court actually treats that kind of case.
Citing Unpublished Opinions in Federal Court
Before 2007, federal circuits had wildly inconsistent rules about citing unpublished opinions. Some allowed it freely, others discouraged it, and a few banned it. Federal Rule of Appellate Procedure 32.1, effective December 1, 2006, set a uniform floor: no federal court may prohibit or restrict the citation of unpublished opinions issued on or after January 1, 2007.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 32.1 – Citing Judicial Dispositions
The rule is narrow on purpose. It guarantees the right to cite but says nothing about the weight a court must give the citation. The advisory committee notes make this explicit: the rule “does not require any court to issue an unpublished opinion or forbid any court from doing so” and “says nothing about what effect a court must give to one of its unpublished opinions.”2Legal Information Institute. Federal Rules of Appellate Procedure Rule 32.1 – Citing Judicial Dispositions You can cite the opinion; the court retains full discretion over how much to credit it.
One procedural requirement: if you cite an unpublished opinion that isn’t available in a publicly accessible electronic database, you must file and serve a copy on all other parties and the court.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 32.1 – Citing Judicial Dispositions This rarely comes up for post-2007 opinions because they’re almost always available electronically.
Opinions issued before January 1, 2007 remain subject to each circuit’s local rules, some of which still restrict citation. Check the issuing circuit’s rules before including an older unpublished decision in a filing.
How Individual Circuits Treat Them
Rule 32.1 is a floor, not a ceiling. Each circuit still sets its own policy on what persuasive weight its unpublished opinions carry, and the differences can affect strategy.
The Ninth Circuit’s Rule 36-3 states flatly that unpublished dispositions “are not precedent,” with narrow exceptions for doctrines like law of the case, claim preclusion, and issue preclusion. Post-2007 opinions can be cited, but the court tells you up front they aren’t precedent. Pre-2007 unpublished opinions may only be cited in narrow circumstances, such as showing double jeopardy, sanctionable conduct, or a conflict among opinions.3U.S. Court of Appeals for the Ninth Circuit. Ninth Circuit Rules – Circuit Rule 36-3
The Second Circuit takes a similar line with its summary orders. Local Rule 32.1.1 provides that summary orders “do not have precedential effect,” and pre-2007 orders generally may not be cited except in narrow circumstances like subsequent stages of the same case or for claim or issue preclusion. When citing a summary order, you must include the notation “summary order” alongside the database citation.4United States Court of Appeals for the Second Circuit. Local Rule 32.1.1 Disposition by Summary Order
Other circuits are less explicit about weight but still treat unpublished opinions as non-binding. Always check the local rules of the circuit where you’re filing. Citation format, permissible uses, and tolerance for persuasive reliance all vary.
Some circuits also allow counsel to move for publication of an unpublished opinion.5U.S. Court of Appeals for the Fourth Circuit. Appellate Procedure Guide – Opinion and Judgment If granted, the opinion is published without any change to the result. The mechanism is rarely used but exists for rulings that turn out more significant than the court first anticipated.
State Courts Follow Their Own Rules
There is no state-level equivalent of Rule 32.1. Some states allow citation of unpublished opinions freely. Others restrict it heavily or prohibit it. A few have adopted depublication procedures, where a higher court can strip a published opinion of its precedential status by ordering it depublished, effectively turning a binding opinion into a non-precedential one — usually without any comment on whether the outcome was correct. Before citing an unpublished state court opinion, check that specific court’s rules. Getting it wrong can result in the citation being struck or your credibility with the judge taking a hit.
The Constitutional Debate
Whether courts can designate their own opinions as non-precedential has been a genuine constitutional question. In Anastasoff v. United States (2000), the Eighth Circuit held that a local rule declaring unpublished opinions non-precedential was unconstitutional under Article III. The court reasoned that the judicial power inherently includes the obligation to follow prior decisions, and that a rule letting judges decide which of their own opinions count as law “expands the judicial power beyond the limits set by Article III.”6Justia Law. Anastasoff v. United States, 223 F.3d 898 The decision was later vacated as moot on rehearing en banc, but the reasoning still appears in scholarly debate.
The Ninth Circuit took the opposite view the following year in Hart v. Massanari (2001), holding that no-citation rules are constitutional. That court concluded that “the principle of strict binding authority is itself not constitutional, but rather a matter of judicial policy,” and that circuits have authority to decide which opinions bind them.
Neither decision controls the other circuit, and the Supreme Court has never directly resolved the question. Rule 32.1 sidestepped the issue by guaranteeing citation rights without addressing precedential weight.
Ethical Duties When Citing Them
ABA Model Rule 3.3(a)(2) requires lawyers to disclose any “legal authority in the controlling jurisdiction known to the lawyer to be directly adverse to the position of the client.”7American Bar Association. Rule 3.3 – Candor Toward the Tribunal The rule doesn’t say whether “legal authority” includes unpublished opinions, and courts and ethics authorities have not uniformly resolved the ambiguity.
When citing an unpublished opinion, be clear about what you’re presenting. Mischaracterizing a non-precedential decision as binding authority can draw sanctions. In jurisdictions that still restrict citation, citing an unpublished opinion in violation of court rules is sanctionable and can result in monetary penalties and, past certain thresholds, a referral to the state bar.
There is also a practical research concern. As one attorney told a Federal Judicial Center survey, permitting citation of unpublished opinions raises “a concern that a lawyer might be deemed to have committed malpractice if he/she did not discover and cite an unpublished opinion on point and favorable to his or her position.”8Federal Judicial Center. Citation of Unpublished Opinions in Federal Appeals With most federal decisions being unpublished, thorough research now means searching beyond the published reporters.
The safest practice is simple. Label unpublished opinions as non-precedential when you cite them. Don’t suggest they carry more authority than they do. Treat your duty of candor as extending to any judicial decision that directly undermines your argument, regardless of publication status. Judges notice when an attorney is playing games with the line between binding and persuasive authority.
