TL;DR
The EFF and partners filed an amicus brief urging the Fourth Circuit to require warrants for border searches of electronic devices. The case involves a man convicted after a warrantless search of his phone revealed child abuse material. The court’s decision could reshape border search policies and privacy protections.
The U.S. Court of Appeals for the Fourth Circuit is considering whether border searches of electronic devices require a warrant, following a case involving a warrantless search that led to a criminal conviction. The Electronic Frontier Foundation (EFF) and other civil rights groups filed an amicus brief urging the court to adopt a warrant standard, citing privacy concerns and legal precedents. This case could significantly influence border search policies and Fourth Amendment protections.
The case, U.S. v. Belmonte Cardozo, involves a U.S. citizen whose phone was manually searched at Dulles Airport after returning from Bolivia. Border officers found child sexual abuse material (CSAM) on his device, leading to his arrest and conviction. The district court had denied his motion to suppress evidence obtained from the warrantless search. The defendant’s legal team, supported by the EFF and other groups, argues that such searches should require a warrant supported by probable cause, consistent with Fourth Amendment protections. The Fourth Circuit previously addressed forensic searches, ruling that they require a warrant, but manual searches are still under debate. In 2024, U.S. Customs and Border Protection (CBP) conducted over 55,000 device searches, both manual and forensic, raising privacy concerns due to the sensitive nature of data stored on electronic devices. The amicus brief emphasizes that the privacy invasion is significant and that a warrant process would not unduly hinder border procedures, as officers can retain devices and seek warrants afterward or invoke exigent circumstances if necessary.
Why It Matters
This case is pivotal because it challenges the longstanding border search exception to the Fourth Amendment, which allows suspicionless searches at U.S. borders. As electronic devices contain highly personal data, the decision could establish new legal standards for digital privacy protections during border crossings. A ruling favoring warrants would reinforce Fourth Amendment rights in the digital age, potentially limiting border searches and prompting policy reforms.

Background
The Fourth Circuit has previously considered border searches of devices, ruling in 2018 that forensic searches require suspicion of transnational offenses, and in 2019 that domestic law enforcement searches at the border need warrants. Manual searches, however, remain contested. The case builds on ongoing debates about digital privacy, with the Supreme Court’s 2014 Riley v. California decision establishing that cell phone searches incident to arrest require warrants. The current case extends this privacy analysis to border searches, where the government argues for broad authority under the border search exception, which historically prioritized security over privacy.
“Border searches of electronic devices should require a warrant supported by probable cause, just like searches of physical luggage.”

“The defendant’s device was searched without a warrant, raising significant privacy concerns.”

What Remains Unclear
It remains unclear how the Fourth Circuit will rule on manual searches of electronic devices and whether they will establish a warrant requirement. The court has previously addressed forensic searches but has not definitively settled the standard for manual searches. The outcome could influence future border search policies and legal interpretations of the Fourth Amendment in digital contexts.

What’s Next
The Fourth Circuit is expected to issue a decision after further deliberation. The ruling could prompt legislative or policy changes, and possibly lead to Supreme Court review if the case or similar cases are appealed. Meanwhile, border agencies may continue current practices until a new legal standard is established.

Key Questions
Why do border searches of electronic devices matter?
Because electronic devices contain highly personal information, and warrantless searches raise significant privacy concerns and legal questions about Fourth Amendment protections in the digital age.
What is the legal basis for requiring warrants at the border?
The Fourth Amendment generally requires warrants supported by probable cause for searches, but the border search exception historically allows suspicionless searches of luggage and vehicles. This case questions whether digital devices should be treated differently.
How could this case affect travelers in the future?
If the court rules that warrants are required for device searches, travelers could have increased privacy protections, and border agencies might need to adapt their procedures to obtain warrants before conducting searches.
What has been the government’s stance on border device searches?
The government argues that border searches are essential for security and that suspicionless searches are justified under the border search exception, especially for devices that may contain contraband or evidence of crimes.
