In Davis v. United States, 564 U.S. 229 (2011), the Supreme Court held 7–2 that evidence obtained by police who followed binding appellate precedent at the time of a search does not have to be suppressed even if the Court later overturns the rule that authorized the search. Applying the exclusionary rule in that situation, the majority said, would punish officers for doing exactly what the law told them to do, and deterrence, the only real purpose of suppression, would gain nothing.1Justia. Davis v. United States, 564 U.S. 229 (2011) The decision drew a sharp line between saying a Fourth Amendment violation occurred and saying suppression is the remedy for it.
How the Case Reached the Court
On an evening in April 2007, Greenville, Alabama police pulled over a car during a routine traffic stop. They arrested the driver, Stella Owens, for driving while intoxicated, and arrested the passenger, Willie Davis, for giving a false name. After handcuffing Davis and placing him in a patrol car, officers searched the vehicle and found a revolver inside his jacket.2Supreme Court of the United States. Davis v. United States 564 U.S. 229 (2011)
Davis, a convicted felon, was indicted for illegal possession of a firearm, convicted by a jury, and sentenced to 220 months in federal prison.3Oyez. Davis v. United States The search followed the rule then in force under New York v. Belton (1981), which let police search a car’s passenger compartment whenever they lawfully arrested an occupant.4Justia. New York v. Belton, 453 U.S. 454 (1981)
While Davis’s appeal was pending, the Supreme Court decided Arizona v. Gant (2009), narrowing Belton sharply. Under Gant, police may search a vehicle after an occupant’s arrest only if the arrested person could still reach the car or if the car likely contains evidence of the crime of arrest.5Justia. Arizona v. Gant, 556 U.S. 332 (2009) Davis was handcuffed in a patrol car when officers searched the vehicle, so the search would have been unconstitutional under Gant. The question for the Court was whether the revolver had to be thrown out even though the officers broke no rule that existed at the time.
What the Court Decided
Justice Samuel Alito, writing for the majority, held that the search violated the Fourth Amendment under Gant but that suppression was not the appropriate remedy. The officers had strictly followed the binding appellate law of their circuit, and the exclusionary rule exists to deter police misconduct, not to punish police for doing what the law required.2Supreme Court of the United States. Davis v. United States 564 U.S. 229 (2011)
The Court tied suppression directly to police culpability. For exclusion to be justified, officer conduct must involve deliberate, reckless, or grossly negligent disregard for constitutional rights. Reliance on existing law falls well short of that.1Justia. Davis v. United States, 564 U.S. 229 (2011) Davis himself conceded the officers had done nothing wrong, which effectively ended his suppression claim.
The standard is objective. Courts do not probe what a particular officer was thinking. They ask whether a reasonably well-trained officer, aware of the appellate decisions governing the jurisdiction, would have believed the search was lawful. If yes, the evidence stays in.
Where Davis Fits in the Good-Faith Line of Cases
The exclusionary rule bars the government from using unconstitutionally obtained evidence at trial, but the Supreme Court has long treated it as a judge-made deterrent tool rather than a personal Fourth Amendment right. When deterrence would gain nothing, the Court has been willing to let evidence in.
That logic produced the good-faith exception in United States v. Leon (1984), where officers relied on a search warrant a judge approved but that turned out to lack sufficient legal support. Excluding the evidence would not teach the police anything, because they had reasonably trusted the warrant.6Justia. United States v. Leon, 468 U.S. 897 (1984) In Illinois v. Krull (1987), the Court extended the exception to officers relying on a state statute later struck down.7Legal Information Institute. Good Faith Exception to Exclusionary Rule In Herring v. United States (2009), it held that negligent police recordkeeping errors do not trigger suppression absent systemic problems or reckless disregard for the Constitution.8Oyez. Herring v. United States
Davis filled in the missing piece. Leon covered warrants. Krull covered statutes. Davis covered binding appellate decisions, which is the form of legal guidance patrol officers actually follow every day. Departments train officers on what the circuits have held, and that training is only as current as the last controlling opinion.
The Griffith Problem: A Violation Without a Remedy
The hardest part of Davis is how it squares with Griffith v. Kentucky (1987). Griffith says a new rule of criminal procedure applies retroactively to every case still on direct appeal.9Justia. Griffith v. Kentucky Davis’s case was on direct appeal when Gant came down, so Gant applied to him. On its face, that ought to mean suppression.
The majority separated two questions the reader may have assumed were one. Retroactivity decides whether a defendant can invoke a new constitutional rule at all. Remedy is a different inquiry. Once the rule applies, the court still has to decide whether suppression follows, and that depends on whether excluding the evidence would deter future police misconduct.1Justia. Davis v. United States, 564 U.S. 229 (2011)
So Davis got to raise the Gant violation. The Court agreed the search was unconstitutional. And the remedy he wanted was still denied. Right without remedy is the shape of the ruling, and it is where much of the scholarly criticism of the case takes root.
The Dissent
Justice Breyer, joined by Justice Ginsburg, argued that the majority hollowed out Griffith. If a defendant can invoke a new Fourth Amendment rule but never actually get evidence suppressed because the officers relied on the old rule, retroactivity becomes a paper guarantee.10Legal Information Institute. Davis v. United States – Dissent
The dissenters also worried about the effect on police training and departmental policy. If evidence gathered under current appellate law is essentially immune from later suppression, departments have less incentive to voluntarily adopt more protective search practices as constitutional standards evolve. Breyer would have applied Gant fully and suppressed the revolver.
What Davis Means for Defendants and Police
The good-faith exception now covers three categories of reasonable police reliance: warrants issued by judges (Leon), statutes passed by legislatures (Krull), and binding appellate court decisions (Davis). The controlling principle across all three is deterrence. Behavior that was lawful under the authorities officers were given cannot be changed by punishing it after the fact.
For a defendant, Davis narrows the window for challenging evidence based on a new Supreme Court ruling. Even when the new rule reaches your case under Griffith, you still have to show that the officers did something blameworthy at the time of the search. Reliance on clear, binding appellate precedent is the opposite of blameworthy.
For law enforcement, the rule is simple: follow the current appellate law of your circuit and the evidence will survive a later change in direction. The protection has limits, though. It extends only to objectively reasonable reliance. Officers who ignore existing precedent, act on superseded law they should know has changed, or stretch a decision beyond what it actually authorizes are not shielded by Davis. The good-faith exception rewards careful policing, not creative policing.
