I don't know, it depends on their mood I guess? I'm unaware of the U.S. legal system specifically, but the Court of Justice of the European Union invalidated laws retroactively in the past. This isn't exclusive to EU laws either. My home country did the same thing with national laws. So I don't know, maybe the US can do that as well, but people just assume the US can't because it feels intuitive for it to be that way?
