Citing Unpublished Opinions: What Rule 32.1 Permits and What Your State Says
Federal Rule of Appellate Procedure 32.1 settled whether you may cite an unpublished federal opinion. It settled nothing about how much that opinion is worth, and it says nothing at all about state court. Here is the working rule, the state patchwork, the citation formats, and how to tell whether a decision is published before you rely on it.
In the federal courts of appeals you may cite an unpublished opinion issued on or after January 1, 2007. Federal Rule of Appellate Procedure 32.1 forbids a court from prohibiting or restricting that citation. It does not make the opinion binding on anyone. State courts set their own rules, and those range from free citation to a flat prohibition.
That gap between may I cite it and what is it worth is where most briefs go wrong.

The federal rule, in its own words
Federal Rule of Appellate Procedure 32.1 took effect December 1, 2006. Subdivision (a) is the operative sentence:
A court may not prohibit or restrict the citation of federal judicial opinions, orders, judgments, or other written dispositions that have been: (i) designated as "unpublished," "not for publication," "non-precedential," "not precedent," or the like; and (ii) issued on or after January 1, 2007.
"Restrict" is doing real work. Before 2006 the circuits ran the full spectrum, from open citation to outright bans, and the Committee Note says the rule replaced those inconsistent standards with one uniform rule. A court may not even tell parties that citing unpublished opinions is discouraged.
Subdivision (b) adds the only procedural burden. If the disposition you cite "is not available in a publicly accessible electronic database," you must file and serve a copy with the brief. Most unpublished federal dispositions sit in Westlaw, Lexis, PACER, or CourtListener, so 32.1(b) rarely bites on appeal. It bites when you cite an unindexed district court order pulled off a docket.
One boundary: the appellate rules govern the courts of appeals. District judges set their own local rules and standing orders. They almost universally accept unpublished appellate dispositions, but Rule 32.1 is not what compels them.
Citable and precedential are two different questions
The rule deliberately left this alone. Its Committee Note states that Rule 32.1 "says nothing about what effect a court must give to one of its unpublished opinions or to the unpublished opinions of another court." Weight is governed by each court's own local rules.
The circuits answered that separate question the same way. Ninth Circuit Rule 36-3 is representative: unpublished dispositions and orders of that court are not precedent, except when relevant under law of the case, claim preclusion, or issue preclusion. So the honest description of a post-2007 unpublished federal disposition is that it is fully citable persuasive authority and nothing more. Our guide to binding versus persuasive authority works through what that buys you.
It cannot resolve a circuit split, overrule a published panel decision, or bind a later panel. Cite it for what it is, a reasoned application of settled law by judges who saw a similar record.
Opinions issued before 2007 follow the old circuit rules
Rule 32.1(a)(ii) is a date limit, not a grandfather clause in your favor. Citation of earlier dispositions is governed by the circuit's own local rule, and the Federal Judicial Center maintains a summary table of what each circuit did. The Ninth Circuit is the strict example again: its pre-2007 unpublished dispositions may not be cited except under law of the case, res judicata, collateral estoppel, or to show double jeopardy. A 2004 memorandum disposition that fits your issue perfectly may simply be off limits.
The state courts are where it actually gets hard
There is no national rule for state practice. Four examples show the spread:
| Jurisdiction | Rule | What it permits |
|---|---|---|
| California | Cal. R. Ct. 8.1115 | Unpublished Court of Appeal opinions "must not be cited or relied on by a court or a party in any other action," except for law of the case, res judicata, collateral estoppel, or a criminal or disciplinary action involving the same person. |
| Washington | Wash. Gen. R. 14.1 | Unpublished Court of Appeals opinions filed on or after March 1, 2013 "may be cited as nonbinding authorities, if identified as such by the citing party." |
| Illinois | Ill. S. Ct. R. 23(e) | Nonprecedential orders entered on or after January 1, 2021 may be cited for persuasive purposes. Older Rule 23 orders remain citable only for double jeopardy, res judicata, collateral estoppel, or law of the case. |
| Michigan | MCR 7.215(C)(1) | An unpublished opinion "is not precedentially binding under the rule of stare decisis." It should not be cited where published authority covers the point, and the citing party must explain the reason for citing it and furnish a copy. |
Three patterns run through the fifty states: outright bars, permission as expressly nonbinding authority (usually with a date cutoff tied to when the state began posting opinions online), and permission only where no published decision reaches the issue, which makes your citation an implicit concession that nothing better exists.
Do not guess which bucket your state falls into. The rule lives in the rules of appellate procedure, in a general or administrative rule outside that set (Washington's is General Rule 14.1; Illinois puts it in Supreme Court Rule 23), or in a local rule of the specific trial court, which can be stricter than the statewide rule. Read it on the court's own website. The 2021 Illinois amendment is a reminder that a page written in 2019 will confidently tell you the opposite of the current rule.
How to tell whether an opinion is published in the first place
The skill the rule presupposes and nobody teaches. Four checks, in order of reliability:
Read the face of the slip opinion. Federal appellate courts print the designation on the first page, in or beside the caption block, in language tracking Rule 32.1: not precedential, not for publication. State courts do the same. This is the authoritative answer and it takes four seconds.
Read the reporter citation. A cite to F.3d or F.4th means the decision was selected for publication. A cite to F. App'x, the Federal Appendix, means the opposite: that reporter existed to collect the decisions courts declined to publish.
Know that F. App'x stopped. Thomson Reuters discontinued it in 2021, ending at volume 861 with Vittetoe v. Blount County, 861 F. App'x 843 (6th Cir. 2021), as law librarians documented at the time. Unpublished federal appellate decisions issued since have no reporter citation at all. If a 2023 court of appeals decision shows only a docket number and a WL number, that absence is the designation.
Know what your free tool does not tell you. CourtListener carries a precedential-status field and exposes it as a search filter, so you can restrict results to published decisions. Google Scholar has no equivalent filter, and nothing in its snippets separates a non-precedential disposition from a published opinion. There, the only reliable check is opening the case and reading page one.
How to cite one correctly
Three formats cover nearly every situation.
In the Federal Appendix (2001–2021). Cite it like any reporter:
Vittetoe v. Blount County, 861 F. App'x 843 (6th Cir. 2021)
Available only in a database. Case name, docket number, database identifier and number, then the court-and-date parenthetical. Pinpoint pages take a star:
United States v. Bennett, No. 05-CR-6050 CJS, 2005 WL 2709572, at *3 (W.D.N.Y. Oct. 21, 2005)
Available in neither. Drop the database identifier, cite by docket number alone, and attach the opinion under Rule 32.1(b):
United States v. Bennett, No. 05-CR-6050 CJS (W.D.N.Y. Oct. 21, 2005)
On the parenthetical: a F. App'x cite already announces the decision's status, and a bare docket-and-WL cite signals it to any experienced reader. Add "(unpublished)," or the court's own term, whenever the local rule requires you to identify it, as Washington's does. Our Bluebook citation guide covers the mechanics.
When an unpublished decision helps, and when it announces weakness
It helps when the point is factual or procedural rather than legal. An unpublished disposition reviewing a discovery sanction for abuse of discretion on a record close to yours shows the court how this plays out without asking it to adopt a rule. It also helps when you are answering an opponent's authority, and when it is the only decision on an unusual statutory provision.
It announces weakness in one situation: when you cite it for a proposition that published authority in the same jurisdiction already covers. Michigan says that out loud in its rule, and judges elsewhere think it either way. Find the controlling authority first, cite the unpublished case second, and make the hierarchy visible on the page. Then run the currency check, because an unpublished decision can be abrogated by later published law with no editorial flag attaching to it — the failure mode our guide to checking whether a case is still good law is written to catch.
The AI wrinkle
Ask a general-purpose chatbot for authority and it will hand back a non-precedential disposition with no designation attached, because the designation lives on the face of an opinion the model never retrieved. It may also hand back a case that does not exist. Neither failure looks different from a good answer, and both have produced sanctions in real courtrooms. CaseRead works the other way around: it searches your firm's case files and the public law together, every citation traces to a source the system actually retrieved, and anything it cannot verify is flagged.
Frequently asked questions
Can you cite an unpublished opinion in federal court?
Yes, in the federal courts of appeals, for dispositions issued on or after January 1, 2007. Rule 32.1(a) says a court may not prohibit or restrict the citation of federal dispositions designated unpublished, not for publication, or non-precedential. Dispositions issued earlier are governed by each circuit's own local rule, and several circuits restrict them.
Are unpublished opinions binding precedent?
No. Rule 32.1 governs citation only. Its Committee Note says the rule "says nothing about what effect a court must give to one of its unpublished opinions or to the unpublished opinions of another court." Circuits still declare their unpublished dispositions non-precedential by local rule, as Ninth Circuit Rule 36-3 does.
What does F. App'x mean in a citation?
F. App'x is the Federal Appendix, the West reporter that collected unpublished federal courts of appeals decisions, so a cite to it means the decision was designated non-precedential. Thomson Reuters discontinued it in 2021 at volume 861. Later unpublished decisions have no reporter cite and are cited by docket number plus a Westlaw or Lexis identifier.
Can you cite an unpublished California opinion?
Generally no. California Rule of Court 8.1115(a) provides that an opinion not certified for publication or ordered published "must not be cited or relied on by a court or a party in any other action." Rule 8.1115(b) carves out law of the case, res judicata, collateral estoppel, and criminal or disciplinary actions involving the same person.
How do you know whether a case is published or unpublished?
Read the first page of the slip opinion, where federal appellate courts print the designation in or near the caption block. Then check the citation: a reporter cite such as F.4th signals publication, while F. App'x or a Westlaw or Lexis number alone signals the opposite. CourtListener has a precedential-status filter. Google Scholar does not.
Do you have to attach a copy of an unpublished opinion to your brief?
In federal appeals, only when the disposition is not available in a publicly accessible electronic database. Rule 32.1(b) then requires the citing party to file and serve a copy with the brief. State rules that permit citation are often stricter: Michigan and Illinois both require furnishing the opinion to the court and opposing counsel every time.
Before you file
The designation changes what you may do with an opinion, what it is worth, and what you must attach. Read it off the face of the decision, check your court's rule, confirm the case is still good law.
