Today, Huawei announced that it has filed a complaint in a US federal court that challenges the constitutionality of Section 889 of the 2019 National Defence Authorisation Act (NDAA).
Through this action, Huawei seeks a declaratory judgement that the restrictions targeting Huawei are unconstitutional and a permanent injunction against the restrictions.
"The US Congress has repeatedly failed to produce any evidence to support its restrictions on Huawei products. We are compelled to take this legal action as a proper and last resort," Guo Ping, Huawei chairman, said.
"This ban not only is unlawful, but also restricts Huawei from engaging in fair competition, ultimately harming US consumers. We look forward to the court's verdict, and trust that it will benefit both Huawei and the American people."
The lawsuit was filed in a US District Court in Plano, Texas. According to the complaint, Section 889 of the 2019 NDAA not only bars all US government agencies from buying Huawei equipment and services, but also bars them from contracting with or awarding grants or loans to third parties who buy Huawei equipment or services, without any executive or judicial process.
This violates the Bill of Attainder Clause and the Due Process Clause. It also violates the Separation-of-Powers principles enshrined in the US Constitution, because Congress is both making the law and attempting to adjudicate and execute it.
Song Liuping, Huawei's chief legal officer, said: "Section 889 is based on numerous false, unproven and untested propositions. Contrary to the statute's premise, Huawei is not owned, controlled or influenced by the Chinese government. Moreover, Huawei has an excellent security record and programme. No contrary evidence has been offered.”
