Yes, and again, I concur with what Professor MacIntosh has to say.
The point I was trying to make and obviously made poorly is that if you have a requirement of consent, it has some unintended consequences that may be problematic, in that in fact now you are involving the parents in being required to agree to the termination of their child's life in a situation in which their child is suffering intolerably.
That is part of the reason why I do not agree with the idea of a requirement of consent—rather, consultation and involvement in the decision-making process. But assuming that the child is decisionally capable which is, of course, the whole basis of the mature minor doctrine, then the ultimate decision is that of the child, but only to be reached after there has been discussion with the parents and discussion with those around in order to assist in a joint decision-making.
All of the evidence around decision-making at end of life for young people suggests that almost always the decisions are reached jointly, so it would be, I expect—
