Lawsuit argues Congress unconstitutionally delegated legislative authority to the EPA

[dunno]

So Chevron was created because there are too many agencies and laws/concerns to manage from Congress.
Kind of ironic as Congress/government created the agencies and laws to begin with.
As usual government creates its own problems with its obsession with control and over-site, which in turn leads to unconstitutional infringements to the ENTIRE bill of rights and more and more taxes to pay for it all.

I have almost zero expectation that the Supreme Court will sort Chevron out.
