... then all the sudden admit it was unconstitutional ...
They haven't admitted it was unconstitutional. They just passed laws to grant the plaintiff's relief. Without the court rendering a judgment, it would imply that it is within the power of states and municipalities to impose firearm restrictions or prohibitions as they please.
I have to wonder if the court would take a dim view of the defendant's proclaimed intent not to defend its case. Isn't it the duty of counsels to argue their cases vigorously, even if they don't believe them?
