ACLU Files Lawsuit Against San Diego Over Automated License Plate Readers

San Diego, CA, September 30, 2026 — The American Civil Liberties Union (ACLU) has initiated legal action against the City of San Diego and its Police Department, challenging the deployment and use of automated license plate readers (ALPRs). The lawsuit was filed recently, though the specific date of filing was not immediately available.

Automated license plate readers are devices equipped with cameras that capture license plate information from passing vehicles. This data is often compiled into databases that can store millions of plate reads, including the date, time, and location of the capture. These systems are used by law enforcement agencies to track vehicle movements.

The ACLU’s lawsuit centers on concerns regarding privacy and the potential for misuse of the data collected by ALPRs. While the specific details of the legal filings were not fully disclosed in the provided summary, such lawsuits typically raise questions about government surveillance, data retention policies, and the impact on civil liberties. The ACLU has historically advocated for strong privacy protections and has expressed concerns that widespread use of ALPRs could lead to a chilling effect on freedom of movement and association.

The summary does not specify the exact nature of the ACLU’s claims, such as allegations of constitutional violations or specific privacy breaches. The legal arguments are expected to address how the collection and storage of license plate data by the San Diego Police Department comply with existing privacy laws and regulations. The potential scope of the ALPR system in San Diego, including the number of readers deployed and the duration for which data is stored, was not detailed in the summary.

The lawsuit signifies a growing debate across the country regarding the balance between public safety objectives and the protection of individual privacy in the age of advanced surveillance technology. The outcome of this litigation could have implications for how law enforcement agencies in San Diego and potentially other municipalities utilize ALPR technology moving forward.

Further details regarding the specific demands of the lawsuit, the legal basis for the ACLU’s claims, and the response from the City of San Diego and its Police Department are anticipated as the legal proceedings develop. Information regarding the contractor that may have supplied the ALPR technology or any prior inspection outcomes related to its use was not provided.
