“Courts must exercise their independent judgment in deciding whether an agency has acted within its statutory authority,” Roberts wrote.
The decision is also a major power grab by the judicial branch, which will now play a bigger role as the final arbiter over which new regulations are allowed to stand and which will be struck down.
