Summary: written with AI from the case record.

What it's about
The Supreme Court overturned that ruling and sent the case back to the lower court (remanded): the emergency exception can apply if police did not violate or threaten to violate the Fourth Amendment; assuming an emergency existed, the Court found no evidence they did so before entering.
Officers knocked at an apartment before entering; drugs found inside became the evidence at issue.
The Fourth Amendment generally requires police to get a warrant before searching a home, though an emergency may be an exception.
Question presented
Does the exclusionary rule, which forbids the use of illegally seized evidence except in emergency situations, apply when the emergency is created by lawful police actions?
What the Court decided
Holding
1. The exigent circumstances rule applies when the police do not create the exigency by engaging or threatening to engage in conduct that violates the Fourth Amendment. 2. Assuming that an exigency existed here, there is no evidence that the officers either violated the Fourth Amendment or threatened to do so prior to the point when they entered the apartment. Pp. 16– 19. 302 S. W. 3d 649, reversed and remanded.
- Result
- Reversed
The Court's reasoning
The Court said the emergency exception may apply when police did not violate or threaten to violate the Fourth Amendment to create the emergency. Assuming an emergency existed, it found no evidence of such conduct before the officers entered.
The vote
From the opinions
“I dissent from the Court’s reduction of the Fourth Amendment’s force.”
What's next
The case returns to Kentucky's courts for further proceedings under the Supreme Court's rule. The Court assumed an emergency existed and did not decide that point.
