Summary: written with AI from the case record.

What it's about
The Court refused to hear his case (denied review), so it did not decide that question.
The case came from the U.S. Court of Appeals for the Ninth Circuit and concerned an exception to the Fourth Amendment’s warrant requirement.
Question presented
Should the “private search” exception to the warrant requirement of the Fourth Amendment be expanded to permit law enforcement to use a private party to conduct a search on the basis the private party had an independent motivation to conduct a search?
