No, I see it as a major victory for all of us.
This means that the EPA can no longer rule “administratively” without having to go to court, and spending time and money, as well as risking losses. And they can’t count on collecting fines until there is a judgment.
Which means that they are much less likely to make decisions like this willy-nilly.
This won’t prevent EPA over-reach, and it will still saddle people with legal costs in those cases, but there should be much less of this stuff.
I understand how you are trying to rationalize this, but it's a lot like saying that something great had happened if they actually reduce the price of gasoline to the level it was on Obamanogeration day. $1.398
