Yesterday, Huawei filed a motion in court to challenge a ban against Huawei in the most recent National Defense Authorization Act (NDAA) passed last August 13, 2018.
The NDAA language banning US government agencies is found here:
(a) Prohibition On Use Or Procurement. – (1) The head of an executive agency may not—
(A) procure or obtain or extend or renew a contract to procure or obtain any equipment, system, or service that uses covered telecommunications equipment or services as a substantial or essential component of any system, or as critical technology as part of any system; or
(B) enter into a contract (or extend or renew a contract) with an entity that uses any equipment, system, or service that uses covered telecommunications equipment or services as a substantial or essential component of any system, or as critical technology as part of any system.
Huawei’s main argument is the ban is unlawful because it targets a specific person – Huawei and its entities.
The NDAA (defense budget) does specifically mention Huawei and ZTE when it included:
(3) COVERED TELECOMMUNICATIONS EQUIPMENT OR SERVICES.—The term “covered telecommunications equipment or services” means any of the following:
(A) Telecommunications equipment produced by Huawei Technologies Company or ZTE Corporation (or any subsidiary or affiliate of such entities).
The government claims the ban is for national security reasons. Previous bans included a federal ban on software from Russia-based Kaspersky Lab. Kapersky also filed a legal challenge but the government prevailed in court due to national security issues. It is unclear whether this court will rule similarly.
Will update as soon as more information becomes available.
