Should police be required to obtain a warrant before tracking a person's cell phone location data?
The 6th District Court of Appeal reversed the 2025 robbery conviction of Marcos Andres Andrade. The court determined that San Jose police failed to justify an emergency exception when obtaining real-time cell phone location data without a warrant.
Why it matters
The ruling underscores that law enforcement must demonstrate specific emergency circumstances to bypass warrant requirements for digital surveillance. It clarifies that the gravity of an offense alone does not permit authorities to ignore constitutional privacy protections.
The court ordered the case back to trial court where Marcos Andres Andrade is now permitted to withdraw his no-contest plea. Andrade has already served a four-year prison sentence for his 2025 conviction.
The players
Marcos Andres Andrade
He is the defendant whose robbery conviction was reversed following a successful appeal regarding warrantless police surveillance.
Erik Johnson
He is the judge who issued a December 2024 order denying the motion to suppress the cell phone data used in the initial trial.
Jesus Ivan Larios
He is an individual involved in the robbery who received a 15-year prison sentence for his participation.
Amanda Estantino
She is the detective who prepared the search and arrest warrant applications that were approved four hours after the initial data request.
The details
Police had requested Andrade’s location data via an emergency disclosure form sent to Verizon, which the company provided within two hours. The appellate court noted that evidence showed police were already conducting surveillance on the suspect, negating the claim that an immediate emergency necessitated bypassing warrant procedures.
Timeline
March 1, 2022: The original robbery and carjacking occurred.
December 2024: The trial court denied a motion to suppress the cell phone data.
October 20, 2026: The appellate court issued its written opinion reversing the conviction.
Legal Context
This decision reinforces Fourth Amendment protections by setting strict limits on how law enforcement uses real-time location tracking. The ruling ensures that digital privacy rights remain a central component of criminal procedure even during active investigations.
This case highlights the standard of evidence required for police to track individuals in the San Jose area without judicial oversight. Residents should be aware that the appellate court has curtailed the use of emergency exemptions for private cellular data.
The takeaway
This ruling demonstrates the judiciary's increasing scrutiny of digital evidence collection practices by law enforcement. It serves as a reminder that privacy rights under the Fourth Amendment remain robust even when investigations involve serious criminal allegations.
