One last note-a criminal court is definitely a constitutional matter. I see no good reason to try to shoehorn it into a constitution that intentionally excluded it when it could be done more neatly in a separate law.
If it's a constitutional matter, it should be
in the Constitution.
But you haven't explained why it should be considered a constitutional matter in the slightest. Me, I don't think a 2/3 majority should be required to change it in the future. It's just an unnecessary threshold. Why do you think a majority isn't enough?
