Chatrie + the Shrinking Third-Party Doctrine: What Data Custodians Should Watch

Short summary

The Supreme Court's Chatrie v. United States ruling narrows the third-party doctrine, requiring warrants for law enforcement to access user data held by companies like Google, even if just two hours of location history. Courts now treat hosted customer data as personally-owned information deserving Fourth Amendment protection. Businesses should review privacy policies and terms of service, as these documents increasingly determine constitutional data protection.
