Quote from their MP, Anna Firth, in a linked article:
“Any decision about removing a child from life-support should, ideally, be made with, not to, those who love them dearly.
“Compassion, communication and mediation must be at the core of the process and, critically, sufficient time to process the tragedy they have been through.
“Dragging them through courts and legal processes with courts and NHS trusts, especially without equal legal representation at the very start, automatically creates an adversarial relationship between the parents and those caring for their child.”
The thing is, that is exactly how the vast majority of these decisions are made in practice. However, she doesn't seem to have any answer for what should happen if parents simply won't accept what they are told no matter how compassionately it's put to them, and if they won't go to mediation. It cannot be the case that in that situation they get their way even if it is not in their child's interests. And what is "sufficient time"? Are we all to be entitled to demand that our dead relatives are kept on life support indefinitely while we process what has happened?
