from the ABA Commission on Immigration – 2019 report (full text linked above):
The immigration courts are facing an existential crisis. The current system is irredeemably dysfunctional and on the brink of collapse, and the only way to resolve the serious systemic issues within the immigration court system is through transferring the immigration court functions to a newly-created Article I court. This approach is the best and most practical way to ensure due process and insulate the courts from the capriciousness of the political environment. It is further our view that the public’s faith in the immigration court system will be restored only when the immigration courts are assured independence and the fundamental elements of due process are met.
