Trying to explain this ruling to my better half...
She finally got it when I pointed out that the EPA was making their own “Law” in the form of “Rules/Regulations”. The Separation of Powers outlined in the Constitution REQUIRE the Congress to pass laws, the “Agencies” enforce those laws as written.
The big grin is developing as I think about BATF, CDC, OSHA, BLM, etc., etc., ad nauseum.
Add DHS to that list; see Cletus’ #1433.
