I blame Congress. It was an abdication of their direct Article I responsibilities to create the ambiguity of "emergency economic powers" in IEEPA in 1977. It is an abdication now to fail to repeal it. Trump is the teenager proving that you shouldn't leave your car keys in the ignition.

SCOTUS abdicated its responsibility to shut down Congress's move to divest its power to tax. POTUS is trying to leverage powers that should never have been granted to attempt to apply the biggest tax increase in human history.
