Overview
On October 2, 2026, Santa Clara County Superior Court Judge Jeffrey El-Hajj dismissed a lawsuit by SIREN and CAIR California that sought to require San Jose police to get a warrant before querying the city's stored license plate reader data. The plaintiffs, represented by the Electronic Frontier Foundation and the ACLU of Northern California, argued that the warrantless searches violate the California Constitution's protections against unreasonable searches and its right to privacy. The city argued that images of vehicles taken on public streets carry no protected privacy interest. Applying a 2024 state appeals court decision on San Diego streetlight cameras, the judge found no reasonable expectation of privacy in the plate data or in later queries of it, and he denied leave to amend. EFF says it will appeal.
Read the full background
San Jose's police department runs a network of 474 Flock Safety license plate reader cameras, according to the city's court brief (opens in a new tab) and KQED (opens in a new tab). The cameras photograph passing vehicles and add each plate and vehicle image to a searchable database. San Jose officers can search that history, and so can officers from other California agencies that San Jose gives access. The plaintiffs' complaint (opens in a new tab) cites city audit records showing 261,711 searches by San Jose police between June 5, 2024 and June 17, 2025, when the city kept the data for a year.
In November 2025, the Electronic Frontier Foundation and the ACLU of Northern California sued the city, Mayor Matt Mahan and Police Chief Paul Joseph on behalf of SIREN, an immigrant services nonprofit, and CAIR California. The complaint does not challenge the real-time matching of plates against hotlists, the plaintiffs' lawyers told KQED (opens in a new tab). It targets later searches of the stored data without a warrant, which it says violate the California Constitution's ban on unreasonable searches and its right to privacy, and it asks the court to require a warrant first.
The city asked the court to dismiss the case in January 2026. Its brief (opens in a new tab) argues that cameras on public streets record only license plates and vehicle exteriors that anyone can see, so drivers have no protected privacy interest in the images. On March 10, 2026, the City Council voted unanimously to cut the default retention period from one year to 30 days, bar cameras near reproductive health facilities and places of worship, and add documentation and authentication requirements for agencies requesting data (KQED (opens in a new tab)). The plaintiff groups said in a joint statement (opens in a new tab) that the changes left warrantless searches in place.
Judge Jeffrey El-Hajj issued a tentative ruling for the city before an August 6, 2026 hearing (KTVU (opens in a new tab)) and then ordered more briefing. His October 2 order (opens in a new tab) says he is bound by People v. Cartwright, a 2024 California Court of Appeal decision holding that police review of San Diego streetlight camera footage of a man on a public street did not require a warrant. He acknowledged that San Jose's system is broader than the cameras in Cartwright but found the difference too small to set that decision aside. He also wrote that fixed plate cameras are less invasive than the cell phone location records in Carpenter v. United States or the Baltimore aerial surveillance program at issue in Leaders of a Beautiful Struggle, and he cited federal trial court decisions that reached similar results. He dismissed all three claims without leave to amend.
City Attorney Susana Alcala Wood said the ruling showed the city's system meets constitutional standards (The Mercury News, via Officer.com (opens in a new tab)). The Electronic Frontier Foundation said on October 13 that it will appeal (opens in a new tab). The ruling came a day after a federal judge in Oklahoma held in United States v. Kyle that a deputy's warrantless Flock query was a Fourth Amendment search, a decision covered in a separate DI case. The two rulings reached opposite results under different constitutions.
San Jose also faces a separate federal lawsuit, filed in April 2026 by three residents represented by the Institute for Justice, which argues that the camera network violates the Fourth Amendment (KQED (opens in a new tab)). In September 2026, city officials disclosed that a police officer had been fired for using the network to help a relative track a woman who had accused the relative of domestic violence (KQED (opens in a new tab)).

SIREN and CAIR California sue San Jose, seeking a warrant requirement for police searches of stored plate reader data
Claim
Represented by the Electronic Frontier Foundation and the ACLU of Northern California, SIREN and CAIR California filed a verified complaint in Santa Clara County Superior Court against the City of San Jose, Mayor Matt Mahan and Police Chief Paul Joseph. It alleges that police searches of the city's stored license plate reader data without a warrant violate article I, sections 1 and 13 of the California Constitution, adds a taxpayer claim, and asks the court to require a warrant before San Jose police or other agencies search the data. The city then kept the data for one year.

San Jose asks the court to dismiss the suit, arguing that plate images from public streets carry no privacy interest
Claim
The San Jose City Attorney's office filed a demurrer asking the court to dismiss all three claims. Its brief argues that the cameras record only images of license plates and vehicle exteriors on public streets, so the plaintiffs cannot show a legally protected privacy interest or a reasonable expectation of privacy, and that the taxpayer claim fails without an underlying violation of law.

However, because the ALPR system collects only images of vehicles from public streets, there is no privacy interest in the information collected.

Electronic Frontier FoundationElectronic Frontier Foundation, co-counsel for the plaintiffs, in a post on its website by Devanshi Nishar and Andrew CrockerDirectly involvedBefore this statement
The Santa Clara County Superior Court dismissed the case on October 2, 2026, a day after a federal judge in Oklahoma held in United States v. Kyle that a deputy's warrantless Flock query violated the Fourth Amendment.
"Make no mistake: We believe this ruling is wrong on the law, and we will appeal. ... Networked ALPRs are not individual streetlight cameras. Their net effect of tracking and mapping cars as they travel reveals patterns of life, intimate relationships, and much more."
CondemnedResponding to: San Jose police searches of the city's stored license plate reader data without a warrant violate the California Constitution's protection against unreasonable searches and seizures (article I, section 13) and its right to privacy (article I, section 1).
Full statement and sources
In an October 13, 2026 post, the Electronic Frontier Foundation said the dismissal is wrong on the law and that it will appeal. It said the court relied on one California appeals court case about individual streetlight cameras, and argued that networked plate readers differ because tracking cars as they travel reveals patterns of life and intimate relationships.
After the statement
The post contrasts the San Jose ruling with the Oklahoma decision and quotes that court's passage contrasting a casual sighting of someone's car with a 30-day log of its movements. It says EFF will keep challenging plate reader systems in court and at the state and local level.

SIREN and CAIR California sued in November 2025, and the city demurred in January 2026, arguing that images of vehicles on public streets carry no protected privacy interest. The court heard the demurrer on August 6, 2026 and then ordered both sides to file supplemental briefs.
"Applying that authority, Plaintiffs’ first and second causes of action do not state sufficient facts because there is no reasonable expectation of privacy in license plate data collected from cameras directed solely at public streets. ... The court concludes that Plaintiffs failed to demonstrate a reasonable expectation of privacy in the capturing of license plate data or in later queries of a database of that license plate data."
Defended or excusedResponding to: San Jose police searches of the city's stored license plate reader data without a warrant violate the California Constitution's protection against unreasonable searches and seizures (article I, section 13) and its right to privacy (article I, section 1).
Full statement and sources
In an order filed October 2, 2026, Judge Jeffrey El-Hajj sustained the city's demurrer to all three claims without leave to amend. Holding that he is bound by People v. Cartwright (2024), he found that the complaint showed no reasonable expectation of privacy in license plate data captured by cameras aimed at public streets, or in later queries of a database of that data. The two state constitutional claims failed on that ground, and the taxpayer claim failed with them.
After the statement
The order acknowledges that San Jose's system is broader in scope than the San Diego cameras in Cartwright but says the case is not different enough to set that precedent aside, and that the court must follow Cartwright unless another appellate court publishes a different position. It also denies the city's request for judicial notice. On October 13, 2026, the Electronic Frontier Foundation said the plaintiffs will appeal.

The reference point is the San Jose Police Department's practice of querying the city's stored license plate reader data without a warrant.

This entry records the ruling the case is about and adds no independent support for either side. The closest competing label is Mixed or conditional, because the order says San Jose's system is broader than the cameras in Cartwright and that a different published appellate decision could change the result; it loses because neither point qualifies the holding, which dismisses every claim without leave to amend.

In a statement to KQED on the day the lawsuit was filed, Mayor Matt Mahan said the city has built data privacy and security measures into its plate reader system, including regular deletion of data not used in an investigation.

At the time, San Jose kept plate data for one year. On March 10, 2026, the City Council voted unanimously to cut default retention to 30 days and add other limits, and Mahan defended the city's approach during the debate, according to KQED.

Memorandum of Points and Authorities in Support of Defendants' Demurrer to Complaint, City of San Jose (January 16, 2026)
Relevant passage: Section I, Introduction, page 1; Section III.B, pages 3 to 5
Excerpt
"However, because the ALPR system collects only images of vehicles from public streets, there is no privacy interest in the information collected."
About this source
The city's brief asking the court to dismiss the complaint, filed January 16, 2026 over the names of City Attorney Susana Alcala Wood and three other lawyers in her office. It argues that photographs of license plates and vehicle exteriors taken on public streets carry no legally protected privacy interest or reasonable expectation of privacy, and that the taxpayer claim fails without an underlying violation.
