Quick Summary

The Second Circuit Court ruled that U.S. border agents do not need a warrant or even reasonable suspicion to search cell phones of travelers entering the country. This decision comes from the case United States v. Alisigwe, involving Chinwendu Alisigwe, who was suspected of fraud and had his phone searched upon returning to the U.S. through JFK Airport. The ruling contrasts with arguments that digital searches should be subject to more stringent requirements akin to those for physical property searches at borders due to the unique nature of cell phones.

Story summary

In a recent ruling, the U.S. Court of Appeals for the Second Circuit upheld that border agents can search travelers' cell phones without a warrant or suspicion of criminal activity. The decision was based on U.S. v. Flores-Montano (2004), where the Supreme Court established that searches at borders are reasonable due to the government's interest in preventing the entry of unwanted persons and effects. This ruling stems from a case involving Chinwendu Alisigwe, a Green Card holder whose phone was searched during his arrival at John F Kennedy International Airport in New York City, leading to his conviction for bank fraud and money laundering. The judges rejected arguments that cell phones should receive special constitutional protection due to the vast amount of personal data they contain, likening digital searches to routine physical luggage checks.Critics argue this decision could undermine freedom of speech and privacy rights, while proponents maintain it is necessary for national security and border control.

Narrative

Because "[t]he Government's interest in preventing the entry of unwanted persons and effects is at its zenith at the international border," United States v. Flores-Montano, 541 U.S. 149, 152 (2004), "searches made at the border, pursuant to the longstanding right of the sovereign to protect itself by stopping and examining persons and property crossing into this country, are reasonable simply by virtue of the fact that they occur at the border," Ramsey, 431 U.S. at 616.

Claims (95 extracted, 12 hedged)

For the last decade or so, lower courts have been grappling with how the Fourth Amendment applies to searches of digital devices such as cell phones at the international border. asserted
Amendment → grapple → border
Physical property can be searched when it crosses the border to advance sovereign interests in preventing the important of contraband, enforcing immigration laws, and making sure tariffs are paid. asserted
tariffs → search → laws
But do these rationales still apply to allow the search of a cell phone? asserted
rationales → apply → phone
When you travel internationally, should the U.S. government be allowed to search your cell phone without limit? asserted
government → travel → limit
Or should a warrant be required, or at least sufficient legal suspicion? My own view is that these government interests aren't advanced by digital searches, and that a warrant should be needed to search a cell phone at the border, at least in the context of devices held by U.S. citizens. asserted
warrant → require → citizens
As I explained my book, The Digital Fourth Amendment, I see this as just like Riley v. California, the case holding that the search-incident-to-arrest exception does not apply to cell phones. asserted
exception → explain → phones
As in Riley, the physical world government interests that justify the rule for physical property just don't carry over to the digital setting. asserted
that → justify → setting
Extending the rule to cell phones has to "rest on its own bottom," Riley tells us, and I don't think it can. asserted
it → extend → us
You can't hide a person in a phone, and the data inside a cell phone isn't subject to tariffs. asserted
data → hide → tariffs
And while there is an interest in preventing contraband from being brought into the country in the form of digital CSAM (child sexual abuse materials), border searches of digital devices aren't actually conducted for that reason. asserted
searches → be → reason
The government searches phones when people cross the border for ordinary criminal enforcement reasons. asserted
people → search → reasons
It's trying to catch bad people, not prevent the importation of contraband. asserted
It → try → contraband
The government is searching at the border only because carrying cell phones paired with traditional border search powers gives them a windfall that helps them catch criminals. asserted
them → search → criminals
I don't think the Fourth Amendment allows them that windfall, given that these searches are categorically undertaken for ordinary criminal law enforcement, not the special sovereignty concerns justifying the border search exception. asserted
searches → think → exception
So I think a warrant is needed, at least for searches of citizens' devices. asserted
warrant → think → devices
If you want the details of my argument, you can read the chapter of the book on this posted at SSRN. asserted
you → want → SSRN
Yesterday, the Second Circuit disagreed, however. asserted
Circuit → disagree → ?
In United States v. Alisigwe, the Second Circuit ruled (per Judge Menashi) that no warrant and not even any suspicion is needed to search a cell phone at the border. asserted
warrant → rule → border
The case involves Chinwendu Alisigwe, a lawful permanent resident who was suspected of engagement in fraud schemes. asserted
who → involve → schemes
Returning to the United States from international flights, Alisigwe was stopped at JFK by border officials who asked him to unlock his phone. asserted
who → return → phone
He did so. asserted
He → do → ?
Border officials looking for fraud records skimmed through his phone and saw evidence of Alisigwe's fraud crimes. asserted
officials → look → crimes
According to the Second Circuit, this was categorically allowed: uncertain
this → accord → Circuit
The "longstanding recognition that searches at our borders without probable cause and without a warrant are nonetheless 'reasonable' has a history as old as the Fourth Amendment itself." asserted
searches → have → Amendment
"The border-search exception is grounded in the recognized right of the sovereign to control, subject to substantive limitations imposed by the Constitution, who and what may enter the country." Id. at 620. uncertain
what → ground → 620
Because "[t]he Government's interest in preventing the entry of unwanted persons and effects is at its zenith at the international border," United States v. Flores-Montano, 541 U.S. 149, 152 (2004), "searches made at the border, pursuant to the longstanding right of the sovereign to protect itself by stopping and examining persons and property crossing into this country, are reasonable simply by virtue of the fact that they occur at the border," Ramsey, 431 U.S. at 616. asserted
they → prevent → 616
Under our precedents, no suspicion is required before the government searches a traveler's property at the border. asserted
government → require → border
Searches of property "are made reasonable by that person's decision to enter this country." asserted
Searches → make → country
To be sure, nonroutine searches, which are "more invasive searches, like strip searches, require reasonable suspicion." Id. asserted
which → require → suspicion
But we have held that "the label 'non-routine' should generally be reserved for intrusive border searches of the person (such as body-cavity searches or strip searches), not belongings." asserted
label → hold → searches
United States v. Levy, 803 F.3d 120, 123 n.3 (2d Cir. 2015) (emphasis added). asserted
emphasis → add → Levy
Because a cellphone is property, our precedents establish that the government does not need to have reasonable suspicion before searching a traveler's cellphone at the border. asserted
government → establish → border
We reject Alisigwe's invitation to extend Riley v. California, 573 U.S. 373 (2014), to conclude that a "search of a cellphone requires a warrant, even in circumstances where a warrantless search is generally allowed." asserted
search → reject → circumstances
Appellant's Br. 32. Riley involved the exception to the warrant requirement for a search incident to an arrest. asserted
Riley → involve → arrest
That exception aims to avoid "the two risks" of "harm to officers and destruction of evidence." asserted
exception → aim → evidence
In Riley, the Court explained that because "[t]here are no comparable risks when the search is of digital data," the rationale for the search-incident-to-arrest exception does not have "much force with respect to digital content on cell phones." asserted
rationale → explain → phones
That holding does not implicate the border-search exception, which relies on a different rationale. asserted
which → implicate → rationale
Alisigwe asks us to limit the border-search exception to exclude searches "for evidence of crime unrelated to contraband or other border offenses." asserted
Alisigwe → ask → contraband
But we have previously held that "the validity of a border search does not depend on whether it is prompted by a criminal investigative motive." asserted
it → hold → motive
Our precedent holding that the government may perform pretextual searches at the border without a warrant means that the government is not limited to searching for contraband or evidence of border offenses. uncertain
government → hold → offenses
