Quick Summary

The U.S. Court of Appeals for the 2nd Circuit ruled on Thursday that government agents can search travelers' cellphones at the border without needing any suspicion of illegal activity. The decision overturns previous rulings in cases like Smith and Sultanov, which required warrants for such searches. This ruling applies to states under the 2nd Circuit’s jurisdiction, including New York, Vermont, and Connecticut, and is based on the historical precedent that border searches do not require probable cause or a warrant.

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.

🔮 In August, U.S. District Court Judge Robert J. Shelby found that federal law did not preempt Utah from enforcing its anti-gambling laws against Kalshi, meaning the platform could not legally operate in the Beehive State.

🔮 If onion futures contracts were legal, farmers could rely on market expectations instead of planting crops based on last year's prices.
🔮 The U.S. income tax rate is low compared to other high-income countries, so Americans living overseas typically pay more in local taxes than they would here.
🔮 In its brief, the NFL points to platforms such as Kalshi for being unwilling to adopt the league's list of prohibited wagers to guard against market manipulation and insider trading and requiring anyone wagering on sports to be at least 21 years old.
🔮 And that might be the tamest idea in this sprawling populist platform.
🔮 On Wednesday, the New York Post reported that the Federal Trade Commission (FTC) would be "ramping up a sweeping probe of Anthropic, OpenAI and other frontier labs to uncover the potential dangers their technology poses to consumers, and plans to slap the tech titans with formal demands, similar to subpoenas, to turn over information."
🔮 In Harlow v. Fitzgerald (1982), the Court established that government officials are entitled to qualified immunity when their conduct does not "violate clearly established constitutional rights of which a reasonable person would have known."
🔮 In another new amicus brief, the Constitutional Accountability Center argues that the border search exception runs counter to the Court's ruling in Riley, allowing federal agents to "rummage at will through the records stored on those devices," effectively giving the federal government the power to "indiscriminately search and seize the 'papers' of the people."
🔮 In an incident that began in May and ended in June, thousands of OpenAI agents hacked into a German wiki site and used it as a message board to cheat on assigned tasks.
🔮 However, the Trump administration has cut much of the voluntary funding sent to the U.N., and the president's 2027 budget would eliminate funding for most U.N. bodies, including its regular budget and peacekeeping operations.

Flores-Montano (2004), the Supreme Court ruled that "the Government's interest in preventing the entry of unwanted persons and effects is at its zenith at the international border," meaning that "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."

Claims (31 extracted, 1 hedged)

Travelers entering the U.S. through New York, Vermont, or Connecticut should be aware: The government can search your cellphone even if it doesn't suspect you of criminal activity. asserted
it → enter → activity
That's the crux of a ruling the U.S. Court of Appeals for the 2nd Circuit released Thursday. asserted
Court → release → Circuit
Judge Steven Menashi writes that "no suspicion is required before the government searches a traveler's property at the border." asserted
government → write → border
Citing the Supreme Court in U.S. v. Ramsey (1977), the 2nd Circuit found that 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 → cite → Amendment
In U.S. v. Smith (2023) and U.S. v. Sultanov (2024)—cases within the 2nd Circuit's jurisdiction—district courts held that law enforcement needed a warrant before searching a suspect's cellphone at the border. asserted
enforcement → hold → border
Thursday's ruling rejects the warrant requirement, setting a precedent for future cases in the 2nd Circuit. asserted
ruling → reject → Circuit
The case was brought by Chinwendu Alisigwe, a permanent resident of the U.S., who was convicted in 2024 of bank fraud, conspiracy to commit bank fraud, and conspiracy to commit money laundering. asserted
who → bring → laundering
In 2018, the United Kingdom Border Task Force seized a fake South African passport with an American nonimmigrant visa for Wilhelm Heintz. asserted
Force → seize → Heintz
The task force shared the passport with the Department of Homeland Security, which matched it to Alisigwe, who had a pending application for naturalization in the United States. asserted
who → share → States
The fake passport led to a joint investigation between U.S. Citizenship and Immigration Services, Homeland Security Investigations (HSI), the HSI Attaché in London, and the Justice Department. asserted
passport → lead → London
In 2019, Alisigwe was returning to America after a trip to Nigeria when HSI and Customs and Border Protection agents stopped him at John F. Kennedy International Airport. asserted
HSI → return → Airport
When an officer showed Alisigwe the fake South African passport, he "denied knowing when or where the photograph was taken." asserted
photograph → show → passport
After instructing Alisigwe to unlock his cellphone, an officer then "scrolled through Alisigwe's cellphone and used his own cellphone to photograph images contained in Alisigwe's photo gallery." asserted
officer → instruct → gallery
A few years later, federal officers stopped Alisigwe at the same airport as he returned from an international trip and "manually reviewed his cellphone by scrolling through it and taking photographs." asserted
he → stop → photographs
After finding further evidence to support the fraud allegations against Alisigwe, officers released him into the country. asserted
officers → find → country
He was "subsequently arrested" and charged with a litany of crimes, and he was ultimately sentenced to five years in prison. asserted
he → arrest → prison
During Alisigwe's initial trial in the U.S. District Court for the Southern District of New York, Judge Valerie E. Caproni denied the defence's motion to suppress evidence obtained from the cellphone. asserted
Caproni → deny → cellphone
Caproni accepted that "cellphone searches cannot be conducted without reasonable suspicion of criminal activity because they are not routine border searches," but she reasoned that law enforcement agents "had reasonable suspicion to do so" both times they searched the phone. asserted
they → accept → phone
The 2nd Circuit's opinion goes beyond Caproni's argument, reasoning that the government's interests at the border supersede an individual's right to privacy. asserted
interests → go → privacy
The 2nd Circuit states that the "level of intrusion into a person's privacy is what determines whether a border search is routine." asserted
search → state → privacy
A search can be considered non-routine, the court declared, only if it involves "intrusive border searches of the person," such as strip searches and body-cavity searches. asserted
it → consider → searches
Since a cellphone is merely property, the 2nd Circuit found that its precedents "establish that the government does not need to have reasonable suspicion before searching a traveler's cellphone at the border." asserted
government → find → border
The ruling reaffirms federal courts' interpretation of the constitutional authority granted to the executive branch at border checkpoints, including airports. asserted
ruling → reaffirm → airports
In U.S. v. Flores-Montano (2004), the Supreme Court ruled that "the Government's interest in preventing the entry of unwanted persons and effects is at its zenith at the international border," meaning that "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." asserted
they → rule → border
While she concurred with the majority's judgment that "neither a warrant nor probable cause is necessary to search a cellphone at an international airport," Judge Eunice C. Lee declined to cosign the court's attempt to "interpret the Fourth Amendment to accept the further (and seemingly inexorable) diminishment of our privacy by way of suspicionless cellphone searches at the border." asserted
Lee → concur → border
Lee took issue with the majority's opinion that federal officials can conduct warrantless searches "with no suspicion and for any reason (including political or discriminatory ones), without implicating constitutional rights." asserted
officials → take → rights
In her concurring opinion, Lee states that the "unparalleled ability of a cellphone search to invade an individual's privacy should be considered when determining whether the searches of these devices at an airport are 'routine.'" asserted
searches → concur → airport
She notes that "while a cellphone search may not be as physically intrusive as a strip search, it is much closer on the spectrum to a strip search than it is to the search of luggage because of the amount of information it reveals." uncertain
it → note → information
As Lee ultimately concludes, the court's decision erodes the Constitution's privacy protections. asserted
decision → conclude → protections
"Allowing suspicionless searches of cellphones at the border undermines the essential privacy principles the Fourth Amendment was intended to protect," she writes. asserted
she → allow → principles
The court, she says, should "hesitate in creating rules that further weaken this cherished constitutional protection." asserted
that → say → protection
