Supreme Court kills suit claiming Cisco helped China persecute dissidents

Supreme Court ruling

The U.S. Supreme Court on June 23 ruled for Cisco Systems and ended a long-running lawsuit brought by Falun Gong practitioners who said the company’s technology helped China track, detain and torture members of the spiritual movement.

The court said American courts were the wrong forum for the case under the Alien Tort Statute and the Torture Victim Protection Act. Justice Amy Coney Barrett wrote the majority opinion. Justice Sonia Sotomayor dissented.

The decision shuts down one of the more closely watched foreign-human-rights cases to reach the court and further narrows the path for similar claims against multinational companies tied to alleged abuses overseas.

What the plaintiffs alleged

The lawsuit was filed in 2011. The plaintiffs said Cisco helped build surveillance tools that were used in China’s campaign against Falun Gong adherents.

Their claims focused on allegations that Cisco technology became part of a system used to identify, monitor and repress Falun Gong believers. AP reported that the litigation was tied to leaked Cisco materials and earlier reporting about China’s "Golden Shield" surveillance project and the targeting of Falun Gong.

The case also reflected a broader legal fight over whether companies can be held liable in U.S. courts for conduct tied to alleged repression abroad when some of the relevant activity has links to the United States.

How the case moved through the courts

A federal district court dismissed the case, but the Ninth Circuit revived it in July 2023 and allowed it to proceed.

The Supreme Court heard argument in April 2026, according to later reporting, before issuing its ruling on June 23.

That ruling reversed the lower-court revival and effectively ends the suit unless there is some separate post-decision litigation or another related case.

The competing accounts

The plaintiffs argued that Cisco knowingly helped create technology used for repression in China. During oral argument, Sotomayor said Cisco "knew that those people will be tortured," according to AP.

Cisco has denied wrongdoing. A Washington Post report quoted a Cisco spokeswoman citing the company’s longstanding statement that it never customized its equipment to help the Chinese government censor, track or intercept communications.

AP also reported that Cisco’s lawyer said the company "vigorously disputes those allegations."

Why the ruling matters

The case matters beyond Cisco because it affects one of the main U.S. legal routes that foreign victims have used to seek redress against companies over alleged abuses abroad.

It may also shield multinational companies from ATS-based exposure connected to foreign government repression, especially when the alleged conduct is partly tied to U.S.-based decision-making or sales.

Sotomayor’s dissent warned that the ruling would close the courthouse doors to nearly all future ATS human-rights claims.

What happens next

The case appears effectively over unless there is further post-decision litigation or a related suit.

Observers will likely watch for reactions from Cisco, the plaintiffs and human-rights advocates, as well as any policy response in Congress.

The ruling is also likely to be cited in future ATS and corporate-aiding-and-abetting cases, where plaintiffs continue to test how far U.S. courts will go in hearing claims tied to conduct outside the country.
