After reading that horrifyingly long court ruling, I have to say I don’t agree that she lacks capacity and understanding of her situation. Earlier in the ruling it stated that she wants to die while trying to live.
Now, I don’t think there’s any chance she survives long enough to join any clinical trial anywhere, nor would I think it’s a good idea to even try, but I don’t think she should be denied her right to refuse palliative care right now. She doesn’t want to take morphine and be rendered unconscious at the moment, but that could change if she becomes uncomfortable enough.
I think saying someone who is lucid and able to discuss their illness can’t make their own medical decisions is a very slippery slope.
Withdrawing dialysis and implementing morphine against someone’s will, is essentially the first steps to non consensual euthanasia. I am a huge fan of a person’s right to die with dignity, but only if it’s their own choice.
