SAN FRANCISCO – U.S. technology companies should be legally accountable in U.S. courts for building tools that purposefully and actively facilitate human rights abuses by foreign governments, the Electronic Frontier Foundation argued in a brief filed Friday to the U.S. Supreme Court. 

The brief filed in the case of Cisco Systems, Inc., et al., v. Doe I, et al. urges the high court to uphold the U.S. Court of Appeals for the 9th Circuit’s 2023 ruling that U.S. corporations can be held liable under the Alien Tort Statute (ATS) – a law that lets noncitizens bring claims in U.S. federal court for international law violations – for taking actions in the U.S. that aided and abetted persecution and torture abroad. 

“This is not a case about a company that merely provided routers or other general-purpose technologies to a foreign government. It is about a company that purposefully and actively assisted in the persecution of a religious group,” the brief says. “There is a growing set of companies—including American companies—that provide surveillance technologies that are vulnerable to, and indeed are being used to, support gross human rights abuses. Because of this, the outcome of this case will have profound implications for millions of people who rely on digital technologies in their everyday lives, including to practice their religion.” 

The “Golden Shield” system that Cisco custom-built for the Chinese government was an essential component of persecution against the Falun Gong religious group—persecution that included online spying and tracking, detention, and torture. Victims reported that intercepted communications were used during torture sessions aimed at forcing them to renounce their religion. Falun Gong victims and their families sued Cisco in 2011 and a federal district judge dismissed the case in 2014. The case was delayed three times as the Supreme Court considered three prior ATS cases.   

The 9th Circuit appeals court – after proceedings including an amicus brief from EFF – reversed that lower decision, holding that U.S. corporations can be held liable under the ATS for aiding and abetting human rights abuses abroad. It also held that a company does not need to have the “purpose” to facilitate human rights abuses in order to be held liable; it only needs to have “knowledge” that its assistance helped in such abuses. It then held that the plaintiffs’ allegations showed that Cisco’s actions met both standards. The court also held that the fact that a technology has legitimate uses does not shield a company from liability for other uses that led to human rights abuses when the standards of international law are met. Taken cumulatively, Cisco’s actions in the U.S. were sufficient to allow the case to proceed, the 9th Circuit ruled.  

Cisco appealed to the Supreme Court, which granted review in January. The case, No. 24-856, is scheduled for argument on April 28. 

Cisco Systems is just one of many U.S. companies that make surveillance systems, spyware, and other products used by governments to violate people’s human rights. 

“This Court must not shut the courthouse door to victims of human rights abuses that are actively powered by American corporations,” the brief says. “In the digital age, repressive governments rarely act alone to violate human rights. They have accomplices—including technology companies that have the sophistication and technical know-how that those repressive governments lack.”
