US Court Allows Warrantless Manual Phone Searches at Airports
A US appeals court said border officers can look through a traveler’s phone by hand without first getting a warrant.
They also do not need to have a specific suspicion about the traveler.
The court said airports are treated like international borders for searches.
It considered a phone to be a kind of property that officers can inspect at the border.
The case involved Chinwendu Alisigwe, whose phone was searched at John F. Kennedy International Airport.
Officers asked him to unlock the phone, viewed photos, and photographed information, including a WhatsApp message.
The court said an earlier Supreme Court decision about phone searches during arrests did not change border-search rules.
The ruling only covers ordinary manual searches.
It did not decide whether more advanced searches that analyze phone data elsewhere need reasonable suspicion.
The Second Circuit ruled that CBP officers may manually search phones at borders and airports without warrants or probable cause.
The court said airports are the functional equivalent of international borders and phones are treated as property.
The ruling followed searches of lawful permanent resident Chinwendu Alisigwe’s phone at John F. Kennedy International Airport.
The court rejected reliance on a 2014 Supreme Court decision providing greater phone privacy during arrests.
The decision applies to manual searches but does not resolve whether forensic, off-site phone analysis requires reasonable suspicion.

Alisigwe challenged the searches, and the dispute raised concerns about privacy when officers inspect personal phone contents.
Relevance of phone privacy precedent
Border Search Authority
The court said the 2014 Supreme Court ruling on phone searches during arrests involved a different legal exception and did not change border-search rules.
Traveler Privacy
The argument against the searches relied on the Supreme Court’s recognition that mobile phones can receive greater privacy protection.
Scope of government access
Border Search Authority
The ruling permits manual inspection of a phone at a border or airport.
