In a decision expected to have significant implications for how law enforcement can obtain location data from technology companies, the United States Supreme Court ruled 6-3 that obtaining detailed cellphone location histories from a technology company constitutes a search under the Fourth Amendment. The ruling comes at a time when technology and privacy are often at odds, and its consequences are likely to affect both users and technology companies.

The case that led to this decision began in 2019, when Virginia police used a geofence warrant to obtain location data from Google for Android devices near the scene of a robbery. Google initially provided anonymized location data for 19 devices. Investigators were able to narrow that data down to 9 and eventually 3 identified users, leading them to Okello Chatrie, who was indicted by a federal grand jury on robbery and weapons charges.
Chatrie, challenging the constitutionality of the investigation, asked for Google's location data to be suppressed, arguing that the police obtained it through an unconstitutional investigation.
The district court agreed that the warrant violated the Fourth Amendment, but refused to suppress the evidence under the good faith exception. Chatrie’s case eventually reached the Supreme Court, which ruled that obtaining such data constitutes research protected by the Fourth Amendment. This means that even when the data only covers a short period of time or is held by a third-party company, it remains protected.
According to the ruling, police must generally obtain a warrant supported by probable cause and describe the scope of the investigation in sufficient detail before accessing them.

This ruling does not prohibit geofencing orders, but it makes clear that this kind of location data is constitutionally protected and cannot be considered freely available to law enforcement as it might have been in the past. While the case involved Google and Android phones, the ruling’s protection of detailed cellphone location histories is not specific to the company and could be extended to comparable records kept by Apple and other tech companies in the future.
The ruling has broader implications for user privacy and the handling of data by tech companies. Tech companies like Google and Apple retain vast amounts of location data, which can reveal detailed information about their users’ movements and activities. The Supreme Court’s ruling means that this data cannot be handed over to authorities without due process of law, thereby protecting users’ privacy.
For law enforcement, this ruling means that procedures for obtaining location data will have to be more stringent and comply with constitutional requirements. This can slow down investigations, but at the same time ensures that citizens’ rights are protected. Authorities will have to be more careful in preparing their warrants, ensuring that each stage of the process is supported by probable cause and is sufficiently specialized.

This decision is an important step toward protecting privacy in an era where technology allows for the easy collection and analysis of personal data. As technology continues to evolve, the legal and constitutional challenges related to privacy and law enforcement are likely to become more complex, making decisions like the Supreme Court’s decision critical in guiding future policies and practices.
