In Davis v. United States, 564 U.S. 229 (2011), the Supreme Court held 7–2 that evidence obtained through a search conducted in objectively reasonable reliance on binding appellate precedent is not subject to the exclusionary rule, even after that precedent is overruled. Justice Alito wrote for the majority, extending the good-faith exception to cover police who followed appellate court rulings that the Supreme Court later changed. The decision preserved Willie Davis’s federal conviction for being a felon in possession of a firearm and reshaped how suppression works when Fourth Amendment law shifts after a search.1Legal Information Institute.

The Facts Behind the Case
In April 2007, officers in Greenville, Alabama stopped a vehicle driven by Stella Owens. Willie Davis was riding as a passenger. When Davis gave the officers a false name, they arrested him, handcuffed him, and placed him in a patrol car. They then searched the passenger compartment and found a revolver inside a jacket that belonged to Davis. Federal prosecutors charged him with being a felon in possession of a firearm, and the revolver became the government’s central piece of evidence.1Legal Information Institute. Davis v. United States
At the time of the search, the officers were operating under New York v. Belton (1981). Belton established a bright-line rule allowing police to search the entire passenger compartment of a vehicle, including containers and clothing inside it, as a lawful incident of arresting a recent occupant.2Justia. New York v. Belton, 453 U.S. 454 (1981) The Eleventh Circuit had long read Belton this way, so the officers had clear, binding authority for what they did.
What Changed Between the Search and the Appeal
While Davis’s case was working its way through the courts, the Supreme Court narrowed Belton sharply. In Arizona v. Gant (2009), the Court ruled that police may search a vehicle incident to an occupant’s arrest only when the arrestee could still reach the passenger compartment, or when the vehicle might reasonably contain evidence of the offense of arrest.3Justia. Arizona v. Gant, 556 U.S. 332 (2009)
Davis’s search failed both parts of the new test. He was already handcuffed in a patrol car with no possible reach into the vehicle. And giving a false name is not an offense that generates evidence to be found in a car. Under Gant, the search was unconstitutional. The question the Supreme Court took up was what to do about it.
The Court’s Holding and Reasoning
The Eleventh Circuit had already sorted the case into two questions before it reached the Supreme Court. First, did the search violate the Fourth Amendment under Gant, which applied retroactively to Davis’s pending appeal? Yes. Second, should the revolver be suppressed as a result? No. Punishing officers for following binding appellate precedent, the Eleventh Circuit reasoned, would not deter future violations. The Supreme Court adopted that framework and affirmed.4Justia. Davis v. United States, 564 U.S. 229 (2011)
Justice Alito built the majority opinion around a single idea: the exclusionary rule exists to deter police misconduct, and nothing else. It is not a personal remedy for the person searched, and its cost, letting guilty defendants go free, is only worth paying when suppression actually changes how officers behave. The decisive variable, Alito wrote, is officer culpability. Deliberate, reckless, or grossly negligent violations warrant suppression. Objectively reasonable conduct does not.
The Greenville officers fell squarely into the reasonable category. They followed the controlling appellate rule as it existed. The constitutional problem lay with the old precedent, not with anything the officers did on the roadside. Suppressing the revolver would penalize compliance with binding law and would not improve police behavior going forward.
Davis extends a well-established line of good-faith cases. United States v. Leon (1984) allowed evidence obtained under a defective warrant.5Legal Information Institute. United States v. Leon, 468 U.S. 897 (1984) Illinois v. Krull (1987) covered reliance on a statute later held unconstitutional.6Legal Information Institute. Illinois v. Krull, 480 U.S. 340 (1987) Herring v. United States (2009) reached isolated negligent recordkeeping.7Legal Information Institute. Herring v. United States Davis added overruled appellate precedent to that list.
Sotomayor’s Concurrence and the Unsettled-Law Question
Justice Sotomayor provided the seventh vote but wrote separately to fence the ruling in. She emphasized that Davis involved appellate precedent that specifically authorized this exact search, endorsed by nearly every court in the country. On those facts, exclusion had no plausible deterrent value.8Legal Information Institute. Davis v. United States – Concurring Opinion
What she refused to sign onto was any broader claim about searches conducted in unsettled legal territory. When no controlling precedent squarely authorizes an officer’s conduct, whether suppression still serves a deterrent purpose is, in her words, an open question. The majority did not decide it, and the concurrence warned lower courts against treating Davis as if it had.
The practical line runs along the clarity of the authority. Officers who follow directly on-point, binding appellate rulings have a safe harbor. Officers acting where the law is mixed or absent do not automatically get the same protection.
The Dissent’s Concern About Frozen Doctrine
Justice Breyer, joined by Justice Ginsburg, dissented. Their central worry was structural. Fourth Amendment law develops because defendants challenge existing rules and sometimes win. If a defendant who successfully proves that a precedent is unconstitutional still cannot get the evidence excluded because police relied on that same precedent, no defendant has any reason to bring the challenge. The incentive to test bad rules collapses, and constitutional doctrine stops correcting itself.9Legal Information Institute. Davis v. United States – Dissenting Opinion
The dissent also framed the case as a stealth retroactivity ruling. Under Griffith v. Kentucky (1987), new constitutional rules of criminal procedure apply to every case still on direct review.10Justia. Griffith v. Kentucky, 479 U.S. 314 (1987) Breyer and Ginsburg argued that letting the good-faith exception block suppression in cases like Davis effectively strips defendants of the benefit of new rules, reviving through the exclusionary rule what Griffith closed off through retroactivity doctrine.11Legal Information Institute. Davis v. United States
What Davis Means for Suppression Motions Today
The concrete change for criminal defense is that winning the Fourth Amendment argument no longer guarantees winning the motion to suppress. A court can find that a search violated the Constitution and still admit the evidence, so long as officers were following clear appellate authority at the time. Timing matters as much as substance: a favorable ruling handed down after the search may prove the violation without producing any remedy.
The ruling’s reach stops where the underlying precedent stops being clear. Sotomayor’s concurrence flagged the gap, and lower courts continue to work through the line between binding appellate authority and merely unsettled law. For police, the safest position remains following the most recent directly controlling decision in the jurisdiction. For defendants, Davis makes the state of the law on the day of the search a threshold question in any suppression fight tied to a doctrinal shift.
