Huawei is suing the U.S. over a law that bans government agencies from buying the Chinese technology giant's equipment, claiming the legislation is unconstitutional, as the company goes on the front foot following months of political pressure.
The lawsuit, which was filed on Thursday local time, focuses on a provision in a law known as the National Defense Authorization Act. Section 889 of that legislation prohibits executive government agencies from procuring telecommunications hardware made by Huawei and another Chinese firm, ZTE. Both companies are explicitly named in the act.
But lawyers for the world's largest network equipment maker by revenue, argued that the provision in the NDAA is against the U.S. Constitution.
Huawei has faced intense pressure from President Donald Trump's administration, which claims the company's equipment could be used for espionage by the Chinese government. The tech giant is also facing criminal charges from the Justice Department, which has accused it of stealing trade secrets and skirting U.S. sanctions on Iran. The U.S. government has also tried to persuade allies against using Huawei gear.
Top executives, including the company's founder, have repeatedly denied the allegations that Huawei is a security risk, while the company has also been carrying out a major public relations push to change its image. The Chinese firm is now going on the legal offensive.
