As municipal automated license plate reader (ALPR) networks expand across the country, a high-stakes legal battle is setting the stage for what civil liberties advocates hope will be a landmark check on government surveillance.

The ongoing federal lawsuit, Schmidt v. City of Norfolk, is currently progressing through the U.S. Court of Appeals for the Fourth Circuit, carrying the potential to deliver a major legal victory for opponents of mass digital tracking.

The case centers on a challenge brought by the Institute for Justice on behalf of local residents against the City of Norfolk, Virginia, over its deployment of 176 fixed-location Flock Safety cameras. The network systematically photographs and logs vehicles traveling on public roads, creating an expansive, searchable database tracking the movements of everyday drivers.

While a lower court ultimately ruled in favor of the city, the decision came packaged with a stark warning that has energized privacy groups. On January 27, 2026, U.S. District Judge Mark S. Davis of the Eastern District of Virginia granted summary judgment to Norfolk, concluding that discrete snapshots from stationary cameras do not cross the threshold of a Fourth Amendment “search” under current precedent.

However, Judge Davis explicitly acknowledged the dragnet nature of the technology, noting that the system “ensnares an immense array of law-abiding citizens guilty of nothing more than driving their cars.” More importantly, the district court issued a direct warning regarding the rapid acceleration of surveillance capabilities: what passes constitutional muster under narrow, piecemeal parameters today risks crossing the line into an unconstitutional, pervasive tracking apparatus as camera densities and analytical tools multiply.

Seizing on that judicial warning, the Institute for Justice appealed the decision to the Fourth Circuit (Docket No. 26-1227), framing the case as a critical test of whether the Fourth Amendment can adapt to modern, aggregated dragnet surveillance.

The appellate phase has drawn heavy national interest. On April 13, 2026, the Institute for Justice filed its formal opening brief.Shortly after, on April 20, 2026, a coalition of major civil liberties and legal organizations—including the American Civil Liberties Union (ACLU), the ACLU of Virginia, the Electronic Frontier Foundation (EFF), the Policing Project, and the Cato Institute—filed a barrage of high-profile amicus curiae briefs. These briefs argue that the lower court fundamentally misread how interconnected ALPR databases and data-retention schedules mimic the continuous, invasive tracking outlawed in landmark precedents like Carpenter v. United States.

Pushback has been equally intense. On June 29, 2026, a coalition of sixteen states and the District of Columbia filed an opposing amicus brief supporting Norfolk, arguing that standard license-plate logging is merely an extension of traditional, permissible police observation in public spaces.

With the briefing cycle having concluded over the summer, the case now awaits placement on the Fourth Circuit’s oral argument calendar. If the appellate court heeds Judge Davis’s underlying warning—and accepts the privacy advocates’ arguments on cumulative digital tracking—Schmidt v. City of Norfolk could provide opponents of mass surveillance with their first major systemic victory against ubiquitous ALPR networks.
