Can Border Agents Search Your Phone? An Update

19 Nov 2019

A federal court in Massachusetts recently issued a ruling that may curtail the expanding practice of government agents searching electronic devices at the U.S. border. In recent years, instances of Customs and Border Patrol (CBP) and Immigration and Customs Enforcement (ICE) agents searching international travelers’ electronic devices as they enter the U.S. have been on the rise. While the actual figures are likely higher, the number of electronic device searches at the border has reportedly risen from 5,100 in 2012 to over 40,000 in 2019.

Border Searches: The Current State of the Law

The Fourth Amendment generally requires law enforcement officers to obtain a warrant based on probable cause before conducting a search or seizure. But there are several exceptions to the warrant requirement, including the border search exception, which allows border agents to conduct routine examinations and seizures of persons and property crossing into the country in order prevent the entry of unauthorized persons or contraband.[1]

Courts in the Fourth and Ninth Circuits have held (and both CBP and ICE policies currently require) that border agents must have reasonable suspicion before conducting a forensic search of an electronic device.[2] Reasonable suspicion requires “a particularized and objective basis for suspecting the particular person stopped of criminal activity” [3] and is a lower standard than probable cause. The CBP and ICE policies refer to a forensic search as an “advanced search,” and define it as “any search in which an officer connects external equipment, through a wired or wireless connection, to an electronic device, not merely to gain access to the device, but to review, copy and/or analyze its contents.”

Nonetheless, under the current policies, when CBP and ICE agents conduct a non-forensic search of an electronic device (referred to in the policies as a “basic search”), no reasonable suspicion or other justification is required. The government agencies take the position that even without cause the border search exception permits these basic searches. While perhaps not as extensive as an advanced search, a basic search is still quite invasive, as agents can view any information on the device, including emails, texts, social media posts, and photos.  

Alasaad v. Nielsen

In May 2018, a group of U.S. citizens and a lawful permanent resident sued the Department of Homeland Security, CBP, and ICE to challenge the constitutionality of the border search policies. Each plaintiff had been subjected at least once to a “basic search” of his or her electronic device where the officer did not have reasonable suspicion for the search. In the course of these basic searches, border agents obtained an array of sensitive information, including privileged attorney-client communications, information related to a plaintiff’s journalism work, a plaintiff’s work product as a NASA employee, social media posts, and photos of a plaintiff and her daughters without their religiously required attire (which, when viewed by male border agents, violated her religious beliefs).

The plaintiffs argued that the searches violated the Fourth Amendment. The court agreed. The court found that because electronic devices like cell phones and laptops contain such a breadth of sensitive personal information, even a basic search of an electronic device resulted in a significant invasion of privacy. After balancing the government’s interest in border protection against individual privacy interests, the court decided that giving the government unfettered access to the contents of electronic devices was not justifiable under the border search exception. The court held that border agents must have reasonable suspicion before conducting any non-cursory search of an electronic device.[4]  

Moreover, the court went out of its way to specify that for a search to be justified under the border search exception, “the reasonable suspicion that is required for the currently defined basic search and advanced search is a showing of specific and articulable facts, considered with reasonable inferences drawn from those facts, that the electronic devices contain contraband.”[5] The contraband element significantly narrows border agents’ authority to search electronic devices and may help prevent fishing expeditions.

Implications and Trends

The government has not yet indicated whether it will appeal the decision or update its policies to reflect the court’s judgment. Additionally, because the court declined to enter a nationwide injunction at this stage in the litigation, the current limits on border agents’ search authority are unclear.

Nonetheless, the decision in Alasaad reflects a growing trend toward recognizing electronic device searches as fundamentally different from searches of other belongings and toward limiting the government’s authority to search electronic devices.  In the opinion, the court relied heavily on the Supreme Court’s decision in Riley v. California, which held that searching the contents of an arrestee’s cell phone did not fall within the warrant exception for searches incident to arrest.[6] The opinion is also consistent with the Supreme Court’s recent decision in Carpenter v. United States, which held that the government generally must obtain a warrant to access cell phone location information and noted that “[w]hen confronting new concerns wrought by digital technology, this Court has been careful not to uncritically extend existing precedents.”[7]

How the government responds to the ruling in this case remains to be seen. And while the decision may ultimately usher in new CBP and ICE policies affording greater protections at the U.S. border, the risk of having your device searched at another country’s borders will remain.

There are many things you can do to protect sensitive information when crossing an international border; below are a few:

  • When traveling internationally, consider taking only a clean smartphone or laptop computer. If there is no sensitive data on the electronic device, there is no risk that such data will be exposed to border officials.
  • If all sensitive data cannot be wiped from electronic device prior to international travel, only take the information needed and remove all unnecessary sensitive data.
  • Inventory all sensitive data contained on any electronic devices that will be taken across the border. That way, if it is accessed, you will know exactly what information was impacted.
  • Fully power down all electronic devices prior to passing through customs. Encryption software is most effective when devices are powered down.
