What the court held

Reasonable suspicion is required for a forensic examination of a laptop seized at the border. It is the comprehensive and intrusive nature of a forensic examination, not the location where it is carried out, that triggers the requirement. Because the agents had reasonable suspicion, the en banc court reversed the order suppressing the evidence.

Why

The court rejected the government's position that no suspicion at all was needed and also rejected the extended-border-search framing, since the traveller's entry was apparent. It weighed the sovereign interest in protecting the border against the privacy interests in the volume of personal data on a portable device, and concluded that reasonable suspicion is a modest and workable standard already used in analogous contexts. It expected officials would continue to conduct forensic examinations where their suspicions were aroused.

Our reading — not the court’s words

Why this matters in practice

Cotterman is the case that first drew the manual/forensic distinction at the border, a year before Riley and five years before Kolsuz followed it. Its key move — locating the constitutional trigger in the method rather than the place — is what makes it operationally relevant to examiners, because the same device can be subject to two different standards depending on how it is examined. It is also a reminder that winning the legal standard and losing the case are compatible outcomes: the defendant established the suspicion requirement and the evidence still came in.
