This has been arguing for ages and ramped up somewhat recently. That and that "Congress should do it's job" and make laws pertaining to *everything*.The heart of the Chevron decision says federal agencies should be allowed to fill in the details when laws aren’t crystal clear. Opponents of the decision argued that it gave power that should be wielded by judges to experts who work for the government.
It is not possible for there to be a law on every little thing as Congress gets tied up all the time and they are not expects in everything. This is the big domino.
It's impossible to stress how important this election and all the little ones going forward are. They are ramping up the return to days past through an activist court.
