A right is “clearly established” for qualified-immunity purposes when, on the date of the incident, existing precedent had already placed the constitutional question “beyond debate.” In practice that means a Supreme Court decision, a published decision of the federal circuit where the incident happened, or a robust consensus of cases from elsewhere, on facts close enough to the conduct at issue. Researching it is a repeatable process: define the right precisely, find binding opinions, and check every decision date against the incident date. Free tools cover nearly all of it.
In 1992, federal marshals and county deputies in Maryland executed an arrest warrant at a family’s home and brought a Washington Post reporter and photographer along. Seven years later, in Wilson v. Layne, the Supreme Court held that bringing the media into a home during a warrant execution violated the Fourth Amendment — and, in the same opinion, held that the officers were immune anyway, because the law had not been settled when they did it. That pairing is the whole problem in miniature. Whether a person can recover for a constitutional violation often depends less on what happened to them than on what the case reporters said beforehand. This guide is for the people who have to go find out: self-represented litigants, law students, and journalists checking a court’s work. It is a research method, not legal advice, and it does not tell anyone what to argue.
Key takeaways
- The test is whether precedent placed the question “beyond debate” on the date of the incident, not today.
- Binding sources come first: the Supreme Court, then published opinions of the federal circuit where the incident occurred.
- Other circuits can matter only as a “robust consensus,” and the Court has not settled whether circuit precedent alone is enough.
- Cases that granted immunity without deciding the constitutional question establish nothing about the right itself.
- CourtListener, Google Scholar, Justia, and Cornell LII are free; PACER charges per page but waives small quarterly bills.
I.What the courts are actually asking
The homepage explains the two-prong test: was a constitutional right violated, and was that right clearly established at the time? This guide is about the second prong, and the first thing to know is that the Supreme Court has defined it narrowly and keeps narrowing it.
The modern formulation comes from Ashcroft v. al-Kidd (2011). The Court said it does “not require a case directly on point, but existing precedent must have placed the statutory or constitutional question beyond debate.” In the same opinion it warned lower courts not to define clearly established law “at a high level of generality.” A general principle — officers may not use excessive force — will almost never be enough by itself.
District of Columbia v. Wesby (2018) describes where that precedent has to come from. The rule must be “settled law,” which the Court said means it is dictated by “controlling authority” or “a robust consensus of cases of persuasive authority.” Wesby added that the principle must clearly prohibit the officer’s conduct “in the particular circumstances before him.” Those phrases trace back to Wilson v. Layne, where the plaintiffs lost because they had pointed to no controlling cases in their jurisdiction at the time of the incident and no consensus of persuasive cases elsewhere.
The standard at a glance
- Wilson v. Layne
- 526 U.S. 603 (1999). Media ride-along into a home violated the Fourth Amendment, but officers were immune because the law was not settled at the time.
- Ashcroft v. al-Kidd
- 563 U.S. 731 (2011). No case “directly on point” is required, but precedent must put the question “beyond debate.”
- D.C. v. Wesby
- 583 U.S. 48 (2018). Law must be dictated by “controlling authority” or “a robust consensus of cases of persuasive authority.”
- Rivas-Villegas v. Cortesluna
- 595 U.S. 1 (2021) (per curiam). Assumed without deciding that circuit precedent can clearly establish law; found the cited case materially distinguishable.
- City of Tahlequah v. Bond
- 595 U.S. 9 (2021) (per curiam). Reversed a denial of immunity because the circuit cases relied on were too different on their facts.
II.Why the incident date controls everything
Clearly established law is measured as of the moment of the conduct. Wilson framed the inquiry around authority that existed “at the time of the incident,” and Wesby speaks of “then-existing precedent.” The practical consequence is blunt: a strong appellate decision handed down a week after an incident does nothing for the person hurt in that incident. It may help the next person.
That is why the first entry in any research file should be the exact date of the event, and why every case collected afterward needs its decision date written beside it. Lawsuits take years, so the gap between the incident and the litigation can be long enough for the law to shift in either direction. A case that looks perfect on the facts can turn out to be useless on the calendar.
There is a second timing trap. Since Pearson v. Callahan (2009), courts may grant immunity on the second prong without ever deciding whether a right was violated. A prior case that ended that way tells a researcher only that the right was not clearly established then; it does not establish the right for anyone later. Our analysis of Zorn v. Linton walks through how that loop operates in a real case.
III.What the recent per curiams add
On the same day in October 2021, the Supreme Court summarily reversed two decisions denying officers qualified immunity, without full briefing or argument. Both are short and worth reading in full, because they show how closely the Court now compares facts.
In Rivas-Villegas v. Cortesluna, the Ninth Circuit had relied on one of its own earlier excessive-force decisions. The Supreme Court did not say circuit precedent counts. It wrote that “even assuming” circuit precedent can clearly establish law for purposes of 42 U.S.C. § 1983, the earlier case was materially distinguishable. That is an assumption, not a holding, and researchers should describe it that way.
In City of Tahlequah v. Bond, the Tenth Circuit had denied immunity to officers who shot a man who raised a hammer in a garage. The Supreme Court reversed, concluding that the circuit precedent relied on was too different from the facts to have given the officers fair notice.
The other direction exists too. In Hope v. Pelzer (2002), the Court recognized that officials can be on notice even in novel factual circumstances when the violation is obvious. Those plaintiff wins are rare enough that we track them separately in When Qualified Immunity Loses.
IV.A step-by-step research method
- Fix the date and the place. Write down the incident date and the state. The state tells you the federal circuit; the U.S. Courts “court locator” and any circuit map will confirm which one.
- Name the right precisely. “Excessive force” is a category, not a right. Describe the conduct the way a court would: the type of force, the person’s behavior, warnings given, whether the person was restrained. The Court’s warnings about generality mean the search terms should be specific.
- Search the Supreme Court first. A Supreme Court decision is controlling everywhere. Search the specific conduct along with the constitutional provision.
- Then search the circuit’s published opinions. Limit results to the relevant circuit. Unpublished opinions may be cited under Federal Rule of Appellate Procedure 32.1, but whether they bind anyone is a question of each circuit’s own rules, so check those rules before relying on one.
- Check every decision date. Anything decided after the incident date drops out of the clearly-established analysis for that incident.
- Read for the holding, not the headnote. Note whether the court actually decided that the conduct violated the Constitution, or only that the law was unsettled. Only the first kind builds the law.
- Check the case’s later history. Use citing-reference features to see whether the opinion was vacated, reversed, reheard en banc, or limited by a later panel.
- Survey other circuits last. If there is no binding authority, collect decisions from other circuits on similar facts and note how many there are and whether any go the other way. That is the raw material for any “robust consensus” question.
V.Free tools and what each is good for
None of this requires a paid legal database, though those are faster. The free options below cover federal opinions well.
| Tool | What it holds | Best use |
|---|---|---|
| CourtListener | Federal and state opinions, plus the RECAP archive of court filings, run by the nonprofit Free Law Project | Filtering by court and date; finding later opinions that cite a case; free copies of filings others have already bought |
| Google Scholar (case law) | Federal and state opinions | Quick keyword searches; the “How cited” view for tracing a case forward |
| Justia | Supreme Court opinions organized by U.S. Reports volume; many circuit opinions | Pulling a Supreme Court opinion from its citation |
| Cornell LII | Supreme Court opinions, the U.S. Code, the federal rules | Reading 42 U.S.C. § 1983 and the appellate rules in clean text |
| PACER | The federal courts’ own docket and filing system | Briefs and orders in similar cases; per-page fees apply, with a quarterly waiver for small bills |
On cost: the judiciary’s PACER pricing page lists a per-page charge with a per-document cap, says judicial opinions are free, and waives fees for any account that runs up $30 or less in a quarter. Check the page itself before relying on those numbers, because the judiciary sets them. Before buying a filing on PACER, search CourtListener’s RECAP archive; someone may already have made it free.
Briefs in comparable cases are underused. Reading how lawyers on both sides framed the clearly-established question in a similar case, and how the court responded, shows which precedents the court took seriously.
VI.A research checklist
- Incident date recorded, and the federal circuit identified.
- The right described in specific, conduct-level terms.
- Supreme Court opinions searched, each with citation and decision date.
- Published circuit opinions searched, each with citation and decision date.
- Every case dated after the incident set aside.
- Each remaining case marked “decided the constitutional question” or “immunity only.”
- Later history checked for every case you plan to rely on.
- Other circuits surveyed and counted, including cases that cut the other way.
- Briefs from comparable cases located on CourtListener or PACER.
- Quotations copied from the opinion itself, with pin cites, never from a summary.
VII.What this research can and cannot tell you
A research file like this can show what the courts had said, and when. It cannot predict how a particular judge will read those cases, and it is no substitute for a lawyer who litigates civil-rights cases in that circuit. Filing deadlines also apply to civil-rights claims and can be short; anyone considering a claim should talk to an attorney promptly rather than finishing the research first.
It also shows something about the doctrine. A test that turns on whether a judge somewhere already ruled on nearly identical facts rewards conduct that is new, not conduct that is lawful. Several states have chosen not to let that test decide their own civil-rights claims; we track them in Which States Have Ended or Limited Qualified Immunity? Congress could make the same choice for federal claims. That is a policy decision, and it is one voters can press.
Frequently asked questions
Does there have to be an earlier case with identical facts?
No. In Ashcroft v. al-Kidd the Supreme Court said it does not require a case directly on point, but existing precedent must have placed the question beyond debate. In practice courts compare facts closely, though Hope v. Pelzer recognized that an obvious violation can be clearly established even in novel circumstances.
Can a court decision issued after the incident make a right clearly established?
Not for that incident. The question is what the law was at the time of the conduct, so later decisions drop out of the analysis for that case, even though they may help people in future cases.
Can decisions from other federal circuits clearly establish a right?
District of Columbia v. Wesby says the law can be settled by controlling authority or by a robust consensus of cases of persuasive authority, so decisions from other circuits can matter collectively. The Supreme Court has not said how many cases make a consensus, and in Rivas-Villegas v. Cortesluna it only assumed that circuit precedent can clearly establish law.
Do unpublished opinions count?
Federal Rule of Appellate Procedure 32.1 allows unpublished federal appellate opinions to be cited, but whether they carry precedential weight depends on each circuit’s own rules. Researchers should check the local rules of the relevant circuit before relying on one.
Is PACER free?
Not entirely. The judiciary charges per page with a per-document cap, but it says judicial opinions are free and it waives fees for accounts that accrue $30 or less in a quarter. CourtListener’s RECAP archive also offers free copies of many filings.
