The Electronic Frontier Foundation (EFF) is urging a federal appeals court to reinstate a lawsuit seeking to hold Cisco Systems accountable for aiding in human rights abuses by building the Chinese government a system that Cisco officials knew was intended to identify—and facilitate the capture and torture of—members of the Falun Gong religious minority. In an amicus brief filed Monday with the United States Court of Appeals for the Ninth Circuit, EFF and the groups ARTICLE 19 and Privacy International argue that the plaintiffs sufficiently alleged that Cisco understood that the “Golden Shield” system (also known as The Great Firewall) it custom-built for China was an essential component of the government’s program of persecution against the Falun Gong—persecution that included online spying and tracking, detention, and torture.
