USA v. Richard Brillhart
Split Score
What is a Split Score?
This score (0-100) indicates how likely this case is to be reviewed by the Supreme Court based on:
Case Summary
Disposition
Affirmed in Part
The Eleventh Circuit upheld most of Richard Brillhart’s convictions for distributing and possessing child pornography, holding that Google’s automated hash-matching of an image in his Gmail account qualified as a private search, so the government’s warrantless review did not violate the Fourth Amendment. It affirmed all other challenged rulings except one Guidelines issue, vacating and remanding for resentencing after finding the district court wrongly applied the § 2G2.2(b)(5) pattern-of-activity enhancement.
Circuit Split Identified
Legal Issue
Whether a technology company’s automated hash-value matching of suspected child-pornography images constitutes a qualifying "private search" that permits subsequent warrantless government review under the Fourth Amendment.
Circuit Positions
Automated hash-value matching is a valid private search that authorizes warrantless government viewing of the matched file.
Hash-value matching alone cannot constitute a private search; government viewing of the underlying file exceeds the scope of any private search and requires a warrant.
Conflict Summary
The Fifth, Sixth, and now Eleventh Circuits treat a hash-value match as the functional equivalent of a prior human inspection; because the match establishes with near-perfect certainty that the file is identical to one already reviewed, law-enforcement viewing of the image reveals no new information and falls within the private-search doctrine. The Second, Fourth, and Ninth Circuits reject that approach, reasoning that a hash value is merely a descriptive label for an unopened digital ‘container,’ so government viewing exposes new, private information and exceeds any prior private search.
