Summary: written with AI from the case record.
What it's about
It said the warrant weakened the link between the stop and the evidence, and that there was no flagrant police misconduct.
Justice Sonia Sotomayor wrote that Fackrell stopped Strieff minutes after he left a home the officer thought might contain drug activity, then checked Strieff’s identification.
The case asked whether an existing arrest warrant could separate evidence from an earlier unlawful stop.
Question presented
Should evidence seized incident to a lawful arrest on an outstanding warrant be suppressed because the warrant was discovered during an investigatory stop later found to be unlawful?
What the Court decided
Holding
The evidence Officer Fackrell seized incident to Strieff’s arrest is admissible based on an application of the attenuation factors from Brown v. Illinois, 422 U. S. 590. In this case, there was no flagrant police misconduct. Therefore, Officer Fackrell’s discovery of a valid, pre-existing, and untainted arrest warrant attenuated the connection between the unconstitutional investigatory stop and the evidence seized incident to a lawful arrest. 2015 UT 2, 357 P. 3d 532, reversed.
- Result
- Reversed
The Court's reasoning
The Court said the valid, pre-existing warrant weakened the link between the unlawful stop and the evidence. It also found no serious police misconduct.
The vote
From the opinions
