Supreme Court to Rule on Police Access to Extensive Cellphone Location Data

The Supreme Court has agreed to examine the constitutionality of police warrants that grant access to vast amounts of cellphone location data. This decision comes amid ongoing debates over the legality of geofence warrants, which have produced conflicting rulings in lower courts. Some jurisdictions argue these warrants violate the Fourth Amendment by being overly broad.
Background of the Geofence Warrants Case
Recent weeks have seen the Supreme Court considering at least two appeals related to this issue. One significant case involves Okello Chatrie, who was convicted of bank robbery in Virginia in 2019. Chatrie’s identification by law enforcement hinged on cellphone location data obtained from Google.
Police utilized geofence warrants to collect location data from devices near the crime scene. This method allowed them to identify specific cellphone owners. However, the appeals claim that this process also accessed anonymized location data from countless individuals uninvolved in any crime, raising privacy concerns.
Previous Supreme Court Rulings
This examination marks a notable point in the legal landscape. Eight years prior, the Supreme Court ruled that law enforcement typically must show probable cause to access cellphone tower data in criminal investigations. Chief Justice John Roberts joined the majority, while three conservative justices—Clarence Thomas, Samuel Alito, and Neil Gorsuch—dissented.
The Virginia Bank Robbery Case
In the Virginia bank robbery, Chatrie allegedly handed a note to the teller demanding over $100,000 and threatening harm if his demands were not met. Initially, police struggled to identify the suspect. However, surveillance footage revealed that Chatrie was using a cellphone during the robbery.
Consequently, law enforcement issued a geofence warrant to Google, requesting location data for all devices near the bank within an hour of the theft. Chatrie was ultimately convicted and received a sentence exceeding 11 years.
Legal Arguments and Implications
- Chatrie’s attorneys argued that magistrate judges require clear guidelines for geofence warrants.
- The federal government maintains these warrants do not amount to a legal search under the Fourth Amendment.
- Users must opt-in to location services, suggesting consent to data sharing for various functions, such as navigation.
Changes in Google’s Data Policies
Last year, Google altered its data storage policy, complicating the compliance with geofence warrants. This development might render the current case moot, as indicated by the federal government. They stated that this policy shift will reduce the occurrence of these warrants in future legal cases.
The Supreme Court’s pending decision could reshape how law enforcement accesses cellphone location data and influence individuals’ privacy rights. This ruling is crucial for balancing law enforcement needs with constitutional protections.
