Is deliberately stopping a treatment which means she will lapse into a coma and die any better really?
Withdrawing treatment that is currently successfully keeping a conscious person alive, when they want that to continue. How is that right either?
If the doctors are right, she's only got a short time left anyway, so why further stress her last few days/weeks/month by insisting on withdrawing treatment. Its unnecessary.
If the doctors aren't right amd she has longer than they anticipate, then thank goodness if they don't withdraw treatment as they'd have been killing her prematurely.
I dont see what the benefits of the Trust's plan is apart from ensuring her bed is freed up in a timely fashion.
They know that legal proceedings will take months by the time inevitable appeals are heard. They don't think she has months, so why being proceedings to shorten her life when shes almost certainly (by their evidence) going to be dead before it concludes.
