I'm impressed that they can so easily dispose of 40 years of law making by Congress that assumed that agencies would interpret the statutes and make rules for regulating their area of authority. Now Congress is going to have to specify every possible consequence of laws in the statutes, otherwise a judge will decide. So agencies will not have any power to actually regulate. Awesome logic work, but terrible legal thin…
They might not do that, but from my initial non-expert read of today's opinion, the Court only looked to the APA, not the Constitution in generating its ruling.
