Sure. I think there are two problems with the 15-day limit. The first is the 15 days during which somebody is compelled to experience enduring and intolerable suffering in order to prove that their wishes are non-ambivalent in circumstances where it's very clear that they're not ambivalent. It's an attempt to protect against ambivalence, but the problem is it's not dealing with a situation in which ambivalence would be a real concern, and it's enforcing a waiting period on everybody when there is no concern about ambivalence.
The second problem with it is that the provision as drafted allows for flexibility only where the death or the loss of capacity is foreseen. It has to be imminent. The problem is, of course, that you can lose capacity unexpectedly. Somebody could have met every single condition. They have met all the criteria. They have met the procedural safeguards. They're waiting those 15 days; they lose capacity; and they're stranded. They will not get help.
I think it's cruel and it's over-inclusive in an attempt to capture something that is understandable, but it's the wrong tool to capture what they're trying to capture.
