Think about this: When the Supreme Court declares a law to be unconsituttional, they don't repeal, just, in effect, order all lower courts not to enforce it. It's as if it never existed.
Interesting point. Let's say that there are a number of cases that have been resolved in lower courts based on an understood interpretation, and that suddenly, the SCOTUS hears an appeal and decides that the formerly operative interpretation needs to be changed.
All of those who had been adversely affected by the former, now "wrong," interpretation aren't immediately made whole. IOW, if they lost $1Million because of it, they don't automatically get that money back ... they get to hire more lawyers, go back to court, and litigate for the return of what in logical effect is rightfully their money. And guess what, Gato, they could still lose!
I definitely feel our pain. Remember your Dickens?
