The Supreme Court’s Chatrie Decision: A Landmark Victory for Digital Privacy and the Fourth Amendment<\/strong><\/h1>\n

When the Framers drafted the Fourth Amendment, they were reacting to the British Crown’s use of “general warrants”\u2014broad authorizations allowing government officials to search first and justify later. Nearly 250 years later, the United States Supreme Court confronted the digital equivalent.<\/span><\/p>\n

In\u00a0Chatrie v. United States<\/b>, the Court addressed one of the most important Fourth Amendment questions of the modern era: Can police obtain the location information of every cell phone near a crime scene in hopes of identifying a suspect?<\/p>\n

The Court answered one question emphatically:\u00a0Yes, obtaining geofence location data is a Fourth Amendment search.<\/b>\u00a0But it deliberately left another critical question for the lower courts:\u00a0When, if ever, is a geofence warrant constitutionally reasonable?<\/b><\/p>\n

What Is a Geofence Warrant?<\/span><\/b><\/h2>\n

Unlike a traditional warrant, a geofence warrant does not begin with a known suspect.<\/span><\/p>\n

Instead, investigators identify a place and time\u2014for example, a bank during the hour surrounding a robbery\u2014and compel a technology company, such as Google, to disclose information about every device within that geographic area.<\/p>\n

Only after reviewing the data do investigators determine who might become a suspect.<\/p>\n

In other words, the investigation starts with everyone.<\/p>\n

The Facts Behind Chatrie<\/strong><\/h2>\n

The case arose from the investigation of a 2019 armed robbery of a credit union in Midlothian, Virginia. Surveillance video showed the robber apparently talking on a cellphone before entering the bank, but investigators had no suspect.<\/span><\/p>\n

Detectives obtained a geofence warrant requiring Google to provide anonymized location information for every device within a 150-meter radius of the bank during approximately one hour surrounding the robbery.<\/p>\n

Google produced data from multiple users. Investigators narrowed the list, requested additional location histories, and ultimately obtained identifying information for three users\u2014one of whom was Okello Chatrie.<\/p>\n

That information became a central piece of the government’s case.<\/p>\n

The Supreme Court’s Holding<\/span><\/b><\/h2>\n

Justice Elena Kagan, writing for a six-member majority, held that law enforcement conducts a\u00a0Fourth Amendment search<\/b>\u00a0when it compels a technology company to disclose an individual’s historical cellphone location data.<\/p>\n

That conclusion is significant.<\/p>\n

For years, prosecutors argued that individuals voluntarily shared their location information with companies like Google and therefore had no reasonable expectation of privacy under the so-called third-party doctrine.<\/p>\n

The Court rejected that argument, recognizing that precise location history reveals “the privacies of life.” A person’s movements can disclose where they worship, receive medical care, meet with attorneys, attend political events, socialize, and live their daily life.<\/p>\n

Simply because that information is stored by a technology company does not eliminate constitutional protection.<\/p>\n

What the Court Did\u00a0Not<\/i>\u00a0Decide<\/b><\/h2>\n

Importantly, the Supreme Court stopped short of declaring all geofence warrants unconstitutional.<\/p>\n

Instead, it sent the case back to the Fourth Circuit to determine whether this particular warrant satisfied the Fourth Amendment’s separate requirements of:<\/p>\n
