Heart of England NHS Foundation Trust v JB  EWHC 342 (COP),  MHLO 9
"My conclusion is that JB undoubtedly has a disturbance in the functioning of her mind in the form of paranoid schizophrenia (as to which she lacks insight), but that it has not been established that she thereby lacks the capacity to make a decision about surgery for herself. On the contrary, the evidence establishes that she does have capacity to decide whether to undergo an amputation of whatever kind. She now appears to be open to having the below-knee operation that the doctors recommend. Whether she has it will be a matter for her to decide for herself with the support of those around her."
