It's nothing of the sort. It's no change at all. The rules that were challenged are already the law in many places. And not hearing a case is not the same thing as making a positive ruling.
Quite wrong. Not hearing a case is indeed a temporary positive ruling. The action in essence says "it is ok with us, until we decide otherwise".
The status now IMO is that any perhaps well-funded community organizers can continue to stack the local city councils and county boards and deprive the citizens of a significant 2dA protection.
You might know that inclusion of the 2dA protection was deemed essential to ratification of the proposed constitution. I.e., abridging the protection means it was all a shell game.
