I think it would make it clearer and would arguably also make it unconstitutional. I think the clear direction from the court in Carter was that this was not about proximity to death; it was about quality of life. To impose that kind of requirement, first of all, is asking physicians and health care providers to do a very difficult task. I think most physicians find forecasting with that level of specificity difficult. I would argue that while it makes it clearer, it undermines the animating purpose for this legislation.
