Is there nothing that you would object to?
Congress has no authority to delegate or grant powers to another branch of government. That requires an amendment agreed to by Congress and the requisite number of States.
The Supreme Court has reversed itself numerous times. There is no such thing as 'settled law'. But the SC was never intended, not is it the only arbiter of what is constitutional.

"When rights secured by the Constitution are involved, there can be no rule making or legislation which would abrogate them." Miranda ~vs~ Arizona, 384 US 436 p. 491.
"An unconstitutional act is not law; it confers no rights; it imposes no duties; affords no protection; it creates no office; it is in legal contemplation, as inoperative as though it had never been passed."
Norton ~vs~ Shelby County, 118 US 425 p. 442.
"The general rule is that an unconstitutional statute, though having the form and name of law, is in reality no law, but is wholly void, and ineffective for any purpose; since unconstitutionality dates from the time of it's enactment, not merely from the date of the decision branding it…"No one is bound to obey an unconstitutional law and no courts are bound to enforce it."
