EFF to Fourth Circuit: Electronic Device Searches at the Border Require a Warrant

Key Takeaways

• EFF and ACLU filed amicus urging warrant for all border device searches.
• FY2025 saw 55,318 CBP manual and forensic electronic searches.
• Court previously required individualized suspicion for forensic, not manual searches.
• Riley v. California precedent supports probable‑cause warrant for border device checks.
• Brief argues warrants won’t impede processing and can be obtained quickly.

Pulse Analysis

Border searches of smartphones and laptops have exploded in recent years, with Customs and Border Protection logging over 55,000 device examinations in fiscal year 2025 alone. While traditional luggage checks are accepted as routine, digital devices contain far more intimate data—political views, health records, and personal communications—making the privacy stakes dramatically higher. The surge in both manual “basic” taps and forensic extractions has sparked a legal debate about whether the longstanding border search exception should extend to modern technology without judicial oversight.

The Fourth Circuit’s upcoming decision could draw a line between historic border authority and contemporary privacy expectations. The amicus brief filed by the EFF and its partners leans on *Riley v. California*, where the Supreme Court ruled that police need a warrant to search a cell phone after an arrest, emphasizing the depth of information stored on modern devices. Earlier Fourth Circuit rulings, such as *U.S. v. Kolsuz* and *U.S. v. Aigbekaen*, required individualized suspicion for forensic searches but left manual inspections on shakier ground. By urging a uniform probable‑cause warrant standard for both manual and forensic searches, the brief seeks to extend Riley’s balancing test to the border context, arguing that the government’s interests can be met without sacrificing travelers’ constitutional rights.

If the court adopts the warrant requirement, agencies will need to integrate rapid judicial review into border operations, a logistical shift the brief claims is feasible and unlikely to delay travelers. Beyond procedural adjustments, the ruling would set a national precedent, prompting other circuits and possibly the Supreme Court to reevaluate the scope of the border search exception. Such a change could curtail mass data harvesting, protect civil liberties, and signal a broader move toward digital privacy safeguards in an era of pervasive surveillance.
