"Huawei asks the court to hold the FCC's order unlawful on the grounds that it fails to offer Huawei required due process protections in labelling Huawei as a national security threat," the Chinese company said in a press release announcing the lawsuit. "Huawei believes that the FCC also fails to substantiate its arbitrary findings with evidence or sound reasoning or analysis, in violation of the US Constitution, the Administrative Procedure Act, and other laws." Huawei said it filed the complaint in the US Court of Appeals for the Fifth Circuit. We haven't been able to get a copy of the lawsuit yet.
