Generally this is a good thing to happen, because it's fairly quick and easy to argue you're in the wrong jurisdiction... and if that's the case, it doesn't matter what the legal theory was, since the court couldn't convict you anyway.
Perhaps selfishly, I'd rather get out of a trial in the motion to dismiss stage, rather than having to very-expensively argue the merits all the way to the end.
Right. I think your parent comment was pointing out that it's not that the legal theory failed, but that it was never tested, and so might (or might not) still be sound.

> If an appeals court says “wrong jurisdiction”, that’s an “rm -rf” on the whole entire case. There’s nothing left to argue about.
I think your parent comment meant something like "the case wasn't overturned on the basis of deficiencies in the legal theory of the crime."
