There is simply no way to look at the agencies pre- and post-Chevron and conclude that the decision did not put more power in the hands of the President and his administration.
Loper Bright overruled Chevron and removed its special deference for statutory interpretation by executive regulatory agencies. More deference to the executive existed under Chevron than now exists under Loper Bright.
Less judicial deference = more executive power? How does that story go?
