Alexander Berengaut

Alex Berengaut is a nationally recognized litigator and co-chair of Covington’s Government Litigation practice group. He has served as lead counsel in a range of commercial disputes and government enforcement proceedings, and currently represents several leading technology companies in litigation and compliance matters relating to data privacy, platform liability, artificial intelligence, and cybersecurity.

In recent years, Alex obtained a series of landmark victories against the federal government in bet-the-company disputes for technology clients. Alex represented TikTok in challenging the Trump Administration’s efforts to ban the app, delivering the winning argument that led the court to enjoin the ban hours before it was set to take effect. He also represented Xiaomi Corporation in challenging the Department of Defense designation that would have blacklisted the company from U.S. financial markets, delivering the winning argument that led the court to enjoin the designation, restoring $10 billion to Xiaomi’s market capitalization.

At the state level, Alex has successfully challenged unconstitutional state legislation and defended against state consumer protection actions. He obtained an injunction blocking Montana’s law banning the TikTok platform, and he secured the outright dismissal of multiple State AG consumer protection lawsuits relating to data privacy and security—a string of victories which resulted in Alex being recognized as Litigator of the Week

Alex has served as counsel to Microsoft Corporation in precedent-setting cases involving government surveillance issues, including Microsoft’s landmark challenge to the government’s attempt to compel disclosure of customer emails stored in Ireland using a search warrant; Microsoft’s First Amendment challenge in the Foreign Intelligence Surveillance Court to restrictions on disclosures about government surveillance; and Microsoft’s constitutional challenge to the statute that allows courts to impose gag orders on technology companies, resulting in nationwide reform of the government’s practices under the statute. 

 Alex maintains an active pro bono practice, focusing on trial-level indigent criminal defense and youth immigration matters. From 2017 to 2020, Alex represented the University of California in challenging the Trump Administration’s rescission of the Deferred Action for Childhood Arrivals (DACA) program, ultimately resulting in a 5-4 victory in the U.S. Supreme Court. See Department of Homeland Security, et al. v. Regents of the University of California et al., 140 S. Ct. 1891 (2020).

On January 12, 2024, California state Assembly member Marc Berman introduced a bill that would impose criminal penalties for the creation, distribution, and possession of child sexual abuse material (CSAM) created using artificial intelligence (AI).  The bill would expand California’s definition of “obscene matter” to include “representations of real or fictitious persons generated through the

In the final days of 2022, President Biden signed into law the “Quantum Computing Cybersecurity Preparedness Act”.  The Act recognizes that current encryption protocols used by the federal government might one day be vulnerable to compromise as a result of quantum computing, which could allow adversaries of the United States to steal sensitive encrypted data.  To address these concerns, the Act will require an inventory and prioritization of vulnerable information technology in use by federal agencies; a plan to migrate existing information technology systems; and reports to Congress on the progress of the migration and funding required. Continue Reading President Biden Signs Quantum Computing Cybersecurity Preparedness Act

Senators Lindsey Graham (R-S.C.), Tom Cotton (R-Ark.) and Marsha Blackburn (R-Tenn.) have introduced the Lawful Access to Encrypted Data Act, a bill that would require tech companies to assist law enforcement in executing search warrants that seek encrypted data.  The bill would apply to law enforcement efforts to obtain data at rest as well as data in motion.  It would also apply to both criminal and national security legal process.  This proposal comes in the wake of the Senate Judiciary Committee’s December 2019 hearing on encryption and lawful access to data.  According to its sponsors, the purpose of the bill is to “end[] the use of ‘warrant-proof’ encrypted technology . . . to conceal illicit behavior.”

In a decision that defines how the Fourth Amendment applies to information collected in the digital age, the Supreme Court today held that police must use a warrant to obtain from a cell phone company records that detail the location and movements of a cell phone user.  The opinion in Carpenter v. United States limits the application of the third-party doctrine, holding that a warrant is required when an individual “has a legitimate privacy interest in records held by a third party.”

The 5-4 decision, written by Chief Justice John Roberts, emphasizes the sensitivity of cell phone location information, which the Court described as “deeply revealing” because of its “depth, breadth, and comprehensive reach, and the inescapable and automatic nature of its collection.”  Given its nature, “the fact that such information is gathered by a third party does not make it any less deserving of Fourth Amendment protection,” the Court held.
