There's a genuine irony sitting at the center of San Jose's current surveillance technology debate: the city that gave the world so much of the hardware, software, and data infrastructure now used for tracking and analysis is itself being sued by two of the country's most prominent digital rights organizations over how its own police department uses exactly that kind of technology. In November 2025, the Electronic Frontier Foundation and the ACLU of Northern California filed suit against the City of San Jose, its police chief, and its mayor, alleging the department's license plate reader program constitutes an unconstitutional mass surveillance system operating without meaningful judicial oversight.
The suit, filed in Santa Clara County Superior Court on behalf of the Services, Immigrant Rights and Education Network and the Council on American-Islamic Relations – California, centers on a specific and genuinely striking set of facts: San Jose Police Department has deployed nearly 500 automated license plate readers across the city's roadways a number the lawsuit describes as more than nearly any other California law enforcement agency operates and retains the collected data for a full year, also longer than most comparable agencies. Between June 2024 and June 2025 alone, the lawsuit alleges SJPD conducted 261,711 searches of this database without obtaining a warrant first, searches that can reconstruct a specific individual's movements over time based purely on where their vehicle has been photographed passing an ALPR camera, without any requirement that the person searched be suspected of wrongdoing.
The technical capability at issue goes beyond simply reading a license plate number. According to the lawsuit, San Jose's ALPR cameras also capture the vehicle's occupants, bumper stickers reflecting political or religious affiliation, make, model, and color, along with GPS coordinates and precise date and time information creating what the plaintiffs describe as a genuinely comprehensive movement-tracking capability rather than a narrow tool limited to identifying specific wanted vehicles.
The lawsuit rests on a constitutional argument with real precedent behind it: location information reflecting a person's physical movements, even when that movement happens in public spaces, is protected under the Fourth Amendment according to existing U.S. Supreme Court case law, and California's own state constitution provides even stronger protection, with both an explicit ban on unreasonable searches and a distinct, separately enumerated right to privacy. The plaintiffs are asking the court to require San Jose police to obtain a warrant before searching the ALPR database, rather than seeking to ban the underlying camera technology or data collection itself a more narrowly tailored legal remedy than the outright technology bans some other California cities have pursued.
San Jose Police Department does maintain a published ALPR usage and privacy policy, required under California's Senate Bill 34, which took effect in 2016 and mandates that agencies operating ALPR technology implement reasonable security procedures and a formal privacy policy governing collection, use, and sharing of the data. The department's policy states ALPR technology should not be used for any purpose other than legitimate law enforcement or public safety purposes. The lawsuit's core allegation isn't that San Jose lacks a policy it's that the department's actual practice of allowing warrantless database searches, even under an existing written policy, still falls short of the constitutional protection the plaintiffs argue location data deserves, regardless of what the department's own internal policy permits.
San Jose's ALPR posture stands in real contrast to other major California cities' approaches to surveillance technology governance. San Francisco, notably, became the first major U.S. city to ban facial recognition technology use by city agencies entirely back in 2019, also requiring Board of Supervisors approval before city departments can purchase other surveillance technology categories including license plate readers and body cameras. San Jose's own governance model, covered in more detail in this site's coverage of the city's broader smart city history, has instead relied on a case-by-case privacy review process that has, in specific instances, rejected certain surveillance proposals but that same review process apparently didn't prevent the ALPR program at the center of this lawsuit from growing to nearly 500 cameras with a full year of data retention, raising a genuine question about whether San Jose's more permissive, technology-by-technology review approach is actually delivering meaningfully different privacy outcomes than a blanket restriction model like San Francisco's would.
It's worth sitting with the specific irony at the heart of this story rather than treating it as a passing rhetorical flourish. The AI-powered image recognition, cloud data storage, and analytics capabilities that make a modern ALPR system possible were substantially developed, refined, and commercialized by companies headquartered in the same Silicon Valley region this lawsuit is playing out in. At the same time, EFF one of the plaintiffs is itself a Bay Area-based digital rights organization, founded in San Francisco in 1990 specifically to defend civil liberties in the digital realm as computing technology became more powerful and more pervasive. San Jose's current ALPR lawsuit is, in a genuine sense, a local instance of a tension the broader tech industry has generated globally: the same innovation ecosystem that builds increasingly powerful surveillance-capable technology also produces some of the most sophisticated and well-resourced organizations dedicated to constraining how that technology gets used by government.
For San Jose residents wanting to understand their own exposure to this system, the department's published ALPR policy and, increasingly, the public record created by the lawsuit itself provide more detail than was previously easily accessible about how the program actually operates camera locations, retention periods, and search volume are now part of the public record in a way that wasn't true before litigation forced more detailed disclosure. Residents concerned about the program have a few concrete avenues: submitting public records requests for specific camera locations and usage data, following the lawsuit's progress through Santa Clara County Superior Court for updates on what additional operational details become public through the discovery process, and engaging with City Council on any future surveillance technology proposals, since the council retains ultimate authority over city policy even when a specific legal dispute is being litigated separately in court.
Regardless of how the lawsuit is ultimately resolved, it's already functioning as a genuine stress test of San Jose's surveillance technology governance model the same city that built a proactive privacy review process specifically to avoid the kind of public trust collapse San Diego experienced with its original smart streetlight program is now facing a comparable legal and public accountability challenge over a different technology that grew large enough, and operated permissively enough, to draw a formal constitutional challenge anyway. For other California cities watching this case, the practical lesson emerging even before a final ruling is that a case-by-case privacy review process, however well-intentioned, doesn't automatically prevent a specific surveillance program from scaling to a point where its cumulative privacy impact draws exactly the kind of legal challenge that more restrictive, blanket governance frameworks are specifically designed to prevent.
Frequently asked questions
Filed in November 2025, it alleges San Jose police conducted 261,711 warrantless searches of license plate reader location data between June 2024 and June 2025, arguing this violates constitutional privacy protections under both the U.S. and California constitutions.
The lawsuit states San Jose has deployed nearly 500 automated license plate readers across the city, more than nearly any other California law enforcement agency, and retains the collected data for a full year.
The plaintiffs are asking the court to require San Jose police to obtain a warrant before searching the ALPR database, rather than seeking to ban the underlying camera technology or data collection entirely.
Yes, required under California's Senate Bill 34 since 2016, but the lawsuit alleges the department's actual practice of warrantless database searches falls short of constitutional privacy protections regardless of what the existing policy permits.
San Francisco banned facial recognition technology entirely in 2019 and requires Board of Supervisors approval before purchasing other surveillance technology, a more restrictive blanket approach than San Jose's case-by-case privacy review model.
According to the lawsuit, the cameras also capture vehicle occupants, bumper stickers, make, model, color, GPS coordinates, and precise date and time information.
