Herring v. United States
The Supreme Court ruled that evidence found during an arrest based on an outdated, mistakenly un-updated warrant database did not have to be thrown out, because the error was an isolated bookkeeping mistake rather than deliberate or reckless police misconduct.
The decision narrows when courts must exclude evidence gathered through police errors, holding that suppression is only justified when police conduct is deliberate, reckless, grossly negligent, or reflects systemic problems — not simple, one-off carelessness.
How it got here: A federal trial court denied Herring's motion to suppress the evidence; the Eleventh Circuit affirmed; Herring asked the Supreme Court to resolve a split among courts on this issue.
The Case in Depth
What happened
A Coffee County officer arrested Bennie Herring after a neighboring county's database showed an active warrant for him. In fact, the warrant had been recalled five months earlier, but no one had updated the database. The search following his arrest turned up methamphetamine and a gun, leading to federal drug and gun possession charges.
The question before the Court
If police arrest someone based on a warrant that had actually been cancelled months earlier due to a database mistake, must the evidence found be thrown out?
Why it matters
Police departments that make isolated recordkeeping mistakes won't automatically lose the ability to use evidence found during resulting arrests. This gives law enforcement agencies less legal pressure to keep warrant databases perfectly current, while defendants harmed by careless (but not reckless or systemic) database errors have fewer options to challenge their arrests in court.
What changes now
This is a final merits decision, so the case itself is over — the Eleventh Circuit's judgment upholding the denial of suppression stands, meaning the drug and gun evidence against Herring remains admissible. Going forward, courts nationwide apply this narrower standard for suppression, evaluating whether police errors are isolated and negligent versus deliberate, reckless, or systemic before excluding evidence.
What this does not decide
The Court did not decide that all police recordkeeping errors are immune from suppression — it said exclusion would still be justified if police were reckless in maintaining warrant systems or knowingly entered false information. The ruling is limited to isolated, negligent errors with no evidence of routine or systemic database problems.
Concurrences and dissents
Dissent — Justice Ginsburg
Justice Ginsburg argued the arrest and search clearly violated the Fourth Amendment and that the exclusionary rule should apply because it deters carelessness just as tort law deters negligence generally. She warned that limiting suppression to deliberate or reckless conduct leaves innocent people with no remedy for database errors, since qualified immunity and municipal liability rules block civil suits, and argued electronic databases' growing role in policing makes accurate recordkeeping especially important.
Dissent — Justice Breyer
Justice Breyer joined Ginsburg's dissent but wrote separately to argue that a prior case, Arizona v. Evans, was actually based on a clear distinction between judicial errors and police errors, not on a case-by-case culpability inquiry. He argued this clean line is easier for courts to apply and would have excluded the evidence because the error here was made by police personnel, not a court employee.
How the Court got there
The legal reasoning, step by step
- The Court explained that the exclusionary rule, which requires suppression of evidence in some Fourth Amendment cases, is not an automatic right of the person searched but a remedy applied only when it will meaningfully deter police misconduct and the benefit outweighs the cost of letting guilty people go free.
- The Court traced its precedents holding that when police act in reasonable, good-faith reliance on information — like a warrant later found invalid — that reliance can prevent the exclusionary rule from applying, because punishing an honest mistake wouldn't deter future violations.
- Looking to the history of the exclusionary rule, the Court noted the doctrine grew out of cases involving flagrant, deliberate constitutional violations, not simple bookkeeping slips, so an isolated negligent error is far removed from the rule's original purpose.
- The Court set the legal standard going forward: exclusion applies only when police conduct is deliberate, reckless, grossly negligent, or part of recurring or systemic negligence, evaluated objectively rather than by examining what was in officers' minds.
- Applying that standard, the Court found the database error here was a one-time negligent slip with no evidence of routine or widespread problems in the county's recordkeeping system, so the marginal deterrent value of suppression did not outweigh the cost of excluding real evidence of crime.

Cases affected by this decision
Reaffirms United States v. Leon (468 U.S. 897)
The Court relied on Leon's good-faith rule as the foundation for finding that isolated negligent errors don't require excluding evidence.
Limits Arizona v. Evans (514 U.S. 1)
The Court extended Evans' good-faith rule for judicial database errors to cover isolated police-caused database errors as well.
