Utah v. Strieff
Headline: Court allows drug evidence found after an unlawful street stop because discovering an outstanding arrest warrant broke the connection, letting officers admit items seized after a warrant-based arrest.
Holding:
- Allows evidence found after a warrant-based arrest to be admitted despite an earlier illegal stop.
- Makes warrant checks during street stops more likely to produce usable evidence.
- May encourage officers to run ID checks to find outstanding warrants.
Summary
Background
A narcotics detective watched a house after an anonymous tip and saw Edward Strieff leave. The officer stopped Strieff in a store parking lot, asked for ID, and ran a database check. The check showed a pre-existing arrest warrant for a traffic violation. The officer arrested Strieff and, during a search incident to that arrest, found methamphetamine and drug paraphernalia. Strieff sought to suppress the evidence as the product of an unlawful stop; Utah courts split on whether the warrant changed that result.
Reasoning
The Court addressed whether finding a valid, pre-existing arrest warrant breaks the link between an earlier unconstitutional stop and evidence found after an arrest. Applying the three Brown factors, the Court said the short time between the stop and the search favored suppression, but the independent intervening circumstance (the untainted warrant) and the officer’s lack of purposeful or flagrant misconduct outweighed that. The majority concluded the warrant compelled a lawful arrest and a lawful search incident to arrest, so the evidence was admissible because the connection was attenuated.
Real world impact
The decision means police may be able to use evidence discovered after an unlawful stop if they discover a valid arrest warrant and then arrest the person. The majority viewed this as an isolated instance; dissents warned the ruling could encourage more stops and routine warrant checks, especially where many outstanding warrants exist. The ruling resolves disagreement among lower courts about how the attenuation rule applies in these situations.
Dissents or concurrances
Two dissenting opinions argued exclusion should apply, warning the decision permits warrant checks to forgive unconstitutional stops and may disproportionately affect communities with many outstanding warrants.
