Arizona v. Evans
Headline: Court limits exclusionary rule, reverses state court, and allows evidence from arrests based on mistaken computerized warrants when the error stems from court clerical recordkeeping.
Holding: The Court reversed the Arizona Supreme Court, holding that the exclusionary rule does not require suppression of evidence seized after an arrest made in objectively reasonable reliance on an erroneous computerized warrant caused by court clerical error.
- Makes it harder to suppress evidence from arrests caused by court clerical computer errors.
- Encourages courts to limit exclusion when police reasonably rely on computerized records.
- Raises concerns about incentives to fix inaccurate databases.
Summary
Background
A driver, Isaac Evans, was stopped for driving the wrong way and arrested after a police computer showed an outstanding misdemeanor warrant that had actually been quashed 17 days earlier. The arresting officer relied on a police computer terminal; a search after the arrest found marijuana. The Arizona Supreme Court had ordered the evidence suppressed because the error in the computerized warrant traceable to court recordkeeping made the arrest unlawful.
Reasoning
The United States Supreme Court accepted the case and applied the framework of United States v. Leon about when suppression deters future violations. The Court held that when an arresting officer reasonably relies on a computerized record, and the erroneous entry resulted from a court clerk’s clerical mistake, the exclusionary rule should not automatically require suppression. The majority concluded that excluding evidence in these circumstances would not significantly deter court clerks and would impose heavy costs. The Court therefore reversed the Arizona Supreme Court. Concurring justices emphasized the narrow scope and warned police must not rely blindly on unreliable systems.
Real world impact
As a practical matter, evidence discovered after similar arrests will be less likely to be thrown out when the mistake came from court recordkeeping and the officer acted reasonably. The decision focuses enforcement attention on police reasonableness and system reliability, not automatic suppression. The ruling does not resolve how to treat other system-wide errors or when police use obviously unreliable databases.
Dissents or concurrances
Justices Ginsburg and Stevens dissented on jurisdiction and policy grounds, arguing the case should have been left to state law and warning that suppression can deter systemic computer errors and protect innocent people.
