Tenth Circuit: 4th Amendment Doesn't Support Broad Search of Protesters' Devices

Background

The U.S. Court of Appeals for the Tenth Circuit overturned a lower court’s dismissal of a challenge to sweeping warrants that sought to search a protester’s devices, digital data, and a nonprofit’s social‑media data.

The case, Armendariz v. City of Colorado Springs (link to case), arose after a 2021 housing protest in Colorado Springs. Police arrested protesters for obstructing a roadway and subsequently obtained warrants to seize and search the devices and data of Jacqueline Armendariz Unzueta, who they alleged had thrown a bike at officers.

The warrants authorized a search of all her photos, videos, emails, text messages, and location data for a two‑month period, plus a time‑unlimited search for 26 keywords—including broad terms such as “bike,” “assault,” “celebration,” and “right.” Police also obtained a warrant to search the Facebook page of the Chinook Center, the organization that organized the protest, even though the Center had never been accused of a crime.

District Court Dismissal

The district court dismissed the civil‑rights lawsuit (complaint link), holding that the searches were justified and that the officers were entitled to qualified immunity (EFF on qualified immunity).

The plaintiffs, represented by the ACLU of Colorado, appealed. The Electronic Frontier Foundation, joined by the Center for Democracy and Technology, the Electronic Privacy Information Center, and the Knight First Amendment Institute at Columbia University, submitted an amicus brief (brief link) in support of the appeal.

Tenth Circuit Decision

In a 2‑1 opinion, the Tenth Circuit reversed the dismissal of the Fourth Amendment search‑and‑seizure claims. The court:

• Found each of the three warrants to be overbroad and lacking particularity regarding scope and duration.
• Held that issuing such facially deficient warrants violated “clearly established” law, so the officers were not entitled to qualified immunity.
• Noted, without explicitly deciding, the broader First Amendment context, including alleged animus by Colorado Springs police toward the protest.

Significance

Appellate courts rarely question the validity of search warrants, and it is even rarer for them to deny qualified‑immunity defenses. The Tenth Circuit’s ruling represents a substantial victory for protesters and for anyone concerned about police immunity when constitutional rights are at stake.

The case has been remanded to the district court for further proceedings, offering an opportunity to further vindicate privacy rights in personal devices and digital data.
