The Hadley case doesn't actually set up a legal precedent because Hadley pleaded guilty as part of a plea deal; as such, there would still be room for a stronger legal defense on the same charge, if not for the Dwight Whorley case. I think the Whorley conviction, which had no such plea deal and stood up to appeals (and which I note was denied further appeal by the Supreme Court earlier this year) will actually stand as the legal precedent.
