Huawei is trying to have a key part of American lawfare against the Chinese company thrown out by a US court – on the grounds it breaks the United States constitution.

The telecoms kit manufacturer is arguing that section 889 of the National Defence Authorisation Act (NDAA) 2019 is unconstitutional under US law because it singles out a single entity – Huawei itself – for "trial by legislature".
