Second Circuit Allows Government to Search Electronic Devices at the Border Without Any Suspicion

United States v. Alisigwe
A Second Circuit case addressing warrantless cellphone searches at the border


NEW YORK—The U.S. Court of Appeals for the Second Circuit today held that border agents may search travelers’ electronic devices without suspicion. The Knight First Amendment Institute at Columbia University and the Reporters Committee for Freedom of the Press (RCFP) submitted an amicus brief in the case, arguing that the court should require the government to obtain a warrant before searching electronic devices at the border, given the implications of those searches for the First Amendment freedoms of speech, association, and the press, and the Fourth Amendment right to privacy. 
“Today’s decision leaves Americans’ most sensitive information open to search at the border without any suspicion at all,” said Scott Wilkens, senior counsel at the Knight First Amendment Institute. “Our phones hold our private thoughts and associations, photographs of our family and friends, and a log of our nearly every movement. The First Amendment should require the government to get a warrant before searching them. We’re disappointed the court declined to recognize that.”
Today’s decision involves a criminal case, United States v. Alisigwe, in which the government relied on evidence obtained from two warrantless searches of the defendant’s cell phone at the border. In November 2023, the district court denied the defendant’s motion to suppress the evidence. The Knight Institute and RCFP’s amicus brief before the Second Circuit pointed to documents obtained by the Knight Institute through FOIA litigation in Knight First Amendment Institute v. Dep’t of Homeland Security and also discussed the burdens these searches place on journalists, whose electronic devices contain sensitive newsgathering information, including the names of confidential sources. The brief argued that the border-search exception to the Fourth Amendment’s warrant requirement does not apply to searches of electronic devices and urged the court to conclude that the First and Fourth Amendments require the government to obtain a warrant before searching a cellphone at the border. The Second Circuit rejected these arguments in today’s ruling.
In March 2025, the Knight Institute’s Wilkens argued before the Second Circuit.

The U.S. Court of Appeals for the Second Circuit recently ruled that border agents are permitted to search travelers' electronic devices without any prior suspicion. This decision has drawn significant criticism from advocacy groups, such as the Knight First Amendment Institute and the Reporters Committee for Freedom of the Press (RCFP), who contended that the ruling jeopardizes fundamental rights guaranteed by the First Amendment freedoms of speech, association, and the press, as well as the Fourth Amendment right to privacy.

The case, United States v. Alisigwe, revolved around the government’s reliance on evidence obtained from warrantless searches of a defendant's cell phone at the border. Advocates argued that the implications of these border searches on personal privacy and constitutional freedoms necessitate a warrant requirement before such searches are conducted. They posited that electronic devices contain highly sensitive information, including private thoughts, personal associations, photographs of family and friends, and detailed logs of movement, which should be protected by warrant protection under the First and Fourth Amendments.

The amicus brief submitted to the court advanced these arguments, contending that the exception to the Fourth Amendment warrant requirement for border searches does not extend to the searching of electronic devices. The advocates urged the court to affirm that the First and Fourth Amendments mandate that the government must obtain a warrant before searching a cellphone at the border. These arguments were further supported by reference to documents obtained through Freedom of Information Act litigation and the documented burdens placed upon journalists whose devices may contain sensitive newsgathering information, such as names of confidential sources. Despite these arguments highlighting the constitutional implications of the government's actions, the Second Circuit ultimately rejected the pleas for a warrant requirement in their ruling.
