I think it doesn't serve the purposes of what Carter was attempting to do, which was to provide access for a certain group of people, because people are disagreeing all over the place. Physicians are disagreeing about what it means. What that tells you is that you are going to go to some physicians who will say, “Yes, you're two years away, and I'm going to read it expansively”, and somebody else is going to be fearful of being charged and read it narrowly, or they're going to be opposed to assisted death and so they will choose to read it very, very narrowly, and say, “maybe a week from death”.
The variability we've seen in the interpretations of the expression among the medical community is absolutely persuasive evidence that this is too vague. It isn't a matter of leaving it to medical determination. It will cease to be vague, and they will figure it out. They will splinter on it.
