China's Huawei sues to challenge US security law

SHENZHEN, China (AP) — Chinese tech giant Huawei is challenging a U.S. law that labels the company a security risk and would limit its access to the American market for telecom equipment.Huawei Technologies Ltd.’s lawsuit, announced Thursday, asks a federal court to reject as unconstitutional a portion of this year’s U.S. military appropriations act that bars the government and its contractors from using Huawei equipment.It comes as the biggest global maker of network equipment fights a U.S. campaign to persuade allies to shun Huawei . That effort threatens to block access to major markets as phone carriers prepare to invest billions of dollars in next-generation, 5G networks.The complaint, filed in Plano, Texas, the headquarters of Huawei’s U.S. operations, cites the framers of the U.S. Constitution, including Alexander Hamilton and James Madison, in arguing that the law in question violates the constitutional separation of powers, denies due process and amounts to a “Bill of Attainder” that singles out a specific entity for adverse treatment.It says the law causes the company “concrete and particularized injury, and imminent future injury” and subjects it to a “burden that is severe, permanent and inescapable” that amounts to a corporate “death penalty.”Huawei, China’s first global tech brand, is at the center of U.S.-Chinese tensions over technology competition and cyber-spying.
