Davis v. United States
The Supreme Court ruled that evidence found during a car search does not have to be thrown out when police were simply following the appeals court's binding rule at the time, even though the Supreme Court later changed that rule in a different case.
The decision expands the 'good-faith' exception to the exclusionary rule, meaning police who reasonably rely on existing appellate precedent won't have their searches punished just because the law shifts underneath them afterward.
How it got here: A federal trial court denied Davis's suppression motion under then-binding Eleventh Circuit precedent; after the Supreme Court decided Gant, the Eleventh Circuit found a constitutional violation but declined to suppress the evidence, and Davis sought Supreme Court review.
The Case in Depth
What happened
Police in Greenville, Alabama, stopped a car, arrested the driver for drunk driving and the passenger, Willie Davis, for giving a false name. After handcuffing both and placing them in separate patrol cars, officers searched the vehicle and found a revolver in Davis's jacket, leading to a federal felon-in-possession charge.
The question before the Court
If police search a car exactly the way binding court precedent allowed at the time, but the Supreme Court later changes that rule, must the evidence be thrown out?
The Court's answer
No — when police search in objectively reasonable reliance on binding appellate precedent that is later overruled, the evidence they find does not have to be excluded from trial. The Court explained that the exclusionary rule exists only to deter police misconduct, and officers who simply follow the rules courts have told them to follow are not engaging in any misconduct that suppression could deter.
The Court distinguished this remedy question from the separate question of whether a new rule applies retroactively. It held that the new rule from Gant did apply to Davis's still-pending case, but that applying it did not automatically mean the evidence must be suppressed — remedy and retroactivity are different issues, and here the "good-faith" exception meant no remedy was available.

Why it matters
Criminal defendants whose cases involve searches that complied with then-existing appellate rules will generally not be able to get evidence suppressed even if the rule is later overturned. This makes it harder for defendants to benefit from favorable changes in Fourth Amendment law that occur while their case is on appeal, while giving police more assurance that following current precedent will protect their searches from later being second-guessed.
What changes now
This is a final merits decision affirming Davis's conviction; the revolver evidence stays in the record and no further proceedings on the suppression issue are contemplated. The ruling establishes going forward that police relying in good faith on binding appellate precedent, even precedent later overturned, generally will not trigger suppression, though the Court left open the possibility of a future exception for the specific litigant who wins a case that overturns a Supreme Court precedent.
What this does not decide
The Court expressly did not decide whether the exclusionary rule applies when police act without any binding precedent at all — that is, when the law is genuinely unsettled. Justice Sotomayor's concurrence emphasized this gap, and the majority left it for a future case.
Concurrences and dissents
Concurrence — Justice Sotomayor
Justice Sotomayor agreed with the outcome but wrote to stress the Court was not deciding whether the exclusionary rule applies when police search under unsettled law rather than clear binding precedent. She argued that in a truly unsettled-law scenario, suppression might still deter constitutional violations by giving officers incentive to err toward compliance, and that culpability is not itself the test — appreciable deterrence and cost-benefit balancing are.
Dissent — Justice Breyer
“Leaving Davis with a right but not a remedy, the Court “keep[s] the word of promise to our ear” but “break[s] it to our hope.””Breyer's objection that the ruling gives Davis a constitutional victory with no practical benefit.
Justice Breyer, joined by Justice Ginsburg, argued the new good-faith exception is incompatible with the Court's retroactivity precedent in Griffith v. Kentucky, wrongly separating the availability of a remedy from retroactive application of a new rule. He warned the ruling would recreate the unworkable, unfair problems of the abandoned Linkletter regime, threaten to swallow the exclusionary rule generally, and would have applied Gant retroactively and required suppression.
How the Court got there
The legal reasoning, step by step
- The Court explained that the exclusionary rule is a court-created deterrent, not a personal constitutional right, and its only purpose is to discourage future police misconduct — so it applies only when suppression would produce meaningful deterrence that outweighs its costs to the justice system.
- Building on its 'good-faith exception' line of cases, the Court noted that deterrence benefits shrink when officers act with an objectively reasonable belief that their conduct is lawful rather than with deliberate, reckless, or grossly negligent disregard for constitutional rights.
- The Court then separated the question of retroactivity — whether a newly announced Fourth Amendment rule applies to a case still on appeal — from the separate question of remedy: even though a new rule applies retroactively, that does not automatically mean suppression is the right response.
- Applying these principles, the Court found the officers here had searched the car in strict, good-faith compliance with binding Eleventh Circuit precedent that was only later overturned, so punishing them through suppression would not deter any future misconduct.
- The Court rejected the argument that withholding suppression would freeze Fourth Amendment law in place, reasoning that other defendants in other circuits, and defendants who argue a precedent is distinguishable, would still have incentives to challenge existing rules.
- The Court concluded that objectively reasonable reliance on binding appellate precedent falls within the good-faith exception, so the exclusionary rule does not apply to the search of Davis's vehicle.

Reaffirms Arizona v. Gant (556 U.S. 332)
The Court applied Gant's new rule retroactively to Davis's case, confirming his search violated the Fourth Amendment.
Reaffirms United States v. Leon (468 U.S. 897)
The Court relied on Leon's good-faith exception framework to extend it to reliance on binding appellate precedent.
Limits New York v. Belton (453 U.S. 454)
Gant had already narrowed Belton's bright-line rule; this case addressed the remedy for searches conducted under the old, broader reading.
