Case Summary

United States v. Carlos Estrada, decided by Seventh Circuit on April 25, 2025, resulted in a defendant win outcome. The Seventh Circuit affirmed the district court's denial of Carlos Estrada's motion to suppress evidence obtained from his cell phone. The court held that Estrada did not have a reasonable expectation of privacy in the location data transmitted by his cell phone to a third-party service provider, even when the data was later accessed by law enforcement. This decision aligns with existing precedent regarding third-party doctrine and the Fourth Amendment. The court held: The court held that Carlos Estrada lacked a reasonable expectation of privacy in the location data transmitted by his cell phone to a third-party service provider, as this data was voluntarily shared with a third party.. Under the third-party doctrine, information voluntarily conveyed to a third party is not protected by the Fourth Amendment's reasonable expectation of privacy.. The court found that Estrada's act of using a cell phone service that inherently transmits location data to its provider constituted a voluntary disclosure of that information.. Accessing this location data by law enforcement, even without a warrant, did not violate the Fourth Amendment because Estrada had no legitimate expectation of privacy in the data once it was shared with the third-party provider.. The court distinguished this case from situations where an individual maintains exclusive control over their data, emphasizing that cell phone location data transmitted to a service provider is not within such exclusive control.. This decision reinforces the broad applicability of the third-party doctrine in the digital age, potentially limiting Fourth Amendment protections for data shared with service providers.
