On Friday October 14, 2026, Santa Clara County Superior Court Judge Jeffrey El-Hajj issued a sustained demurrer without leave to amend in SIREN v. City of San Jose — dismissing the EFF + ACLU of Northern California challenge to warrantless police searches of San Jose’s ALPR database, and finding that “based on one California appeals court case involving individual streetlight cameras, people do not have a reasonable expectation of privacy when driving on a public road.”[1][7]

Thirteen days earlier — on October 1, 2026 — a federal district judge in Oklahoma had ruled the opposite way on the same constitutional question, calling Flock ALPR queries “a type of indiscriminate mass surveillance” and suppressing evidence obtained through a single warrantless plate read on the basis of out-of-state plates alone.[1][4] The inverse-day pair is the first documented federal/state constitutional split on ALPR technology in U.S. history [unverified] — and it places any LATAM CCTV/ALPR procurement office signing a U.S.-anchored vendor contract in Q4 2026 in a structurally novel situation: the same vendor’s architecture is currently constitutional in California state court and unconstitutional in federal court.[1][3]

The California ruling turns on a single 2024 California Court of Appeal decision (People v. San Diego streetlight camera case, 4th Dist.) that the trial court applied to find drivers lack privacy expectations on public roads.[5][6] EFF + ACLU argued that a network of nearly 500 ALPR cameras continuously photographing every car and retaining the data “for a month or longer” is constitutionally distinguishable from a single streetlight camera — but the court rejected that argument.[1][7] EFF announced it will appeal; a second civil case targeting the same San Jose ALPR system is procedding in federal court.[3][6][unverified]

The numbers behind the California ruling: the San Jose network logs “millions of records per month about people’s movements” and retains the data for an entire year per EFF’s complaint.[7] The city council reduced retention to 30 days in March 2026 under public pressure; a police officer was fired in April for allegedly sharing ALPR location data with his cousin; San Jose’s own police chief Paul Joseph disclosed the firing in September.[6][7] The dismiss-and-appeal cadence is itself a structural datapoint: California state courts are not yet ready to recognize ALPR aggregation as a Fourth-Amendment-style invasion, while federal courts (at least the Northern District of Oklahoma) are now willing to.[1][3][4]

For a Mexican, Brazilian, or Argentine procurement office signing an enterprise ALPR/CCTV contract in Q4 2026, the inverse-day pair creates a dual-track constitutional exposure that vendors cannot guarantee away.[3][6] The Kyle ruling is a single district-court decision that the Hill opinion itself acknowledges is “the first of its kind”[1] — but it is now binding precedent in the Northern District of Oklahoma and is being briefed across four additional federal circuits (Fifth Brownlee, Fourth Schmidt, Seventh Scholl).[4] The SIREN dismissal is binding in California state court until the appeal resolves, which will take 12-24 months.[3][unverified]

Three concrete clauses your LATAM ALPR CCTV RFP needs:

(1) Warrant-at-access-or-state-constitutional-analog clause: the vendor warrants in writing that any government query on the customer’s footage or plate reads requires a documented warrant-equivalent before access, OR alternatively that the vendor’s architecture is demonstrably compliant with the most privacy-protective state constitutional analog in the customer’s jurisdiction (in LATAM: artículo 16 CPEUM México / art. 5 CF Brasil / art. 19 CADH Argentina).[1][7] This clause operationalizes the dual-track risk: the customer’s RFP cannot anticipate which state or federal court will hear the next constitutional challenge, so the vendor must warrant compliance with the highest common denominator across the customer’s jurisdictional footprint.[unverified]

(2) Single-camera-vs-network-aggregation-audit clause: the vendor warrants that the architecture of its system can be audited and demonstrated to be distinguishable from a “networked” 500-camera aggregation under the EFF framing that “Networked ALPRs are not individual streetlight cameras.”[1][2][7] Concretely: per-camera data retention ≤30 days, queryable cross-camera aggregation disabled by default, off-network sharing audit log exposed to the customer.[3][6] This clause is the operational answer to the single most important distinction the EFF brief made and the California trial court rejected: a single camera is constitutional in California, a 500-camera aggregation is not (the EFF argument the court did not adopt).[1][3][5]

(3) Constitutional-appeal-track-disclosure clause: the vendor warrants disclosure within 14 days of any pending federal or state constitutional decision that may affect the customer’s deployment.[3][4] EFF’s appeal in SIREN v. San Jose will reach the California Court of Appeal within 6-12 months [unverified]; four ALPR-related federal circuit decisions are pending; a fifth federal civil case against San Jose is now active.[3][6] For a LATAM customer whose RFP is signed in Q4 2026, the constitutional landscape is fundamentally unstable for the next 24 months — and the vendor must contractually commit to disclosure so the customer can re-evaluate before deploying.[4][7]

P.D. If your CCTV/ALPR vendor told you today “our system meets U.S. constitutional standards,” ask which U.S. — the federal courts that just suppressed evidence in Oklahoma, or the California courts that just dismissed the constitutional challenge?[1][3] If the answer is “both,” ask them to show you the warrant-at-access / single-camera-vs-network-aggregation / constitutional-appeal-track-disclosure clauses in writing.[3][6][7] If they only show you generic compliance language and not the three clauses by name, you have your answer — and your next RFP revision has three new sections.[unverified]
