This is certainly playing with words though. Trying to frame administrative law as a bastion of democracy just because it was created by congress is a severe reach no matter how you do it. It's like saying the Byzantine emperor was selected by the senate. That's factual, but isn't really giving you a good picture of how things work.
Administrative law is inherently less democratic.
Yes and congress holds impeachment and appointment powers over the judicial branch, as well as the ability to hold hearings to investigate them. NEITHER are inherently democratic. A bill creating law is democratic, administrative law is efficient.
