“For the purposes of this Act a person lacks capacity in relation to a matter if at the material time he is unable to make a decision for himself in relation to the matter because of an impairment of, or disturbance in the functioning of, the mind or brain.”
“(1) For the purposes of section 2 a person is unable to make a decision for himself if he is unable: (a) to understand the information relevant to the decision; (b) to retain that information; (c) to use or weigh that information as part of the process of making the decision; or (d) to communicate his decision (by talking, using sign language or any other means).”
“5.31 All reasonable steps which are in the person's best interests should be taken to prolong their life. There will be a limited number of cases where treatment is futile, overly burdensome to the patient or where there is no prospect of recovery. In circumstances such as these, it may be that an assessment of best interests leads to the conclusion that it would be in the best interests of the patient to withdraw or withhold life-sustaining treatment, even if this may result in the person's death. The decision-maker must make a decision based on the best interests of the person who lacks capacity. They must not be motivated by a desire to bring about the person's death for whatever reason, even if this is from a sense of compassion. Healthcare and social care staff should also refer to relevant professional guidance when making decisions regarding life-sustaining treatment. 5.32 As with all decisions, before deciding to withdraw or withhold life-sustaining treatment, the decision-maker must consider the range of treatment options available to work out what would be in the person's best interests. All the factors in the best interest’s checklist should be considered, and in particular, the decision-maker should consider any statements that the person has previously made about their wishes and feelings about life-sustaining treatment. 5.33 Importantly, section 4(5) cannot be interpreted to mean that doctors are under an obligation to provide, or to continue to provide, life-sustaining treatment where that treatment is not in the best interests of the person, even where the person's death is foreseen. Doctors must apply the best interests' checklist and use their professional skills to decide whether life-sustaining treatment is in the person's best interests. If the doctor's assessment is disputed, and there is no other way of resolving the dispute, ultimately the Court of Protection may be asked to decide what is in the person's best interests.” (Emphasis supplied.)
"I cannot see that medical treatment is appropriate or requisite simply to prolong a patient's life when such treatment has no therapeutic purpose of any kind, as where it is futile because the patient is unconscious and there is no prospect of any improvement in his condition (p 869)"
“(a) The patient demonstrates no visual response and very limited responses to auditory and somatic stimuli in very limited measure response. (b) The patient has extensive brain damage caused by chronic excessive alcohol consumption and subdural haemorrhaging and a secondary haemorrhage or cerebral vasospasm causing cerebral infarction. (c) Although there is evidence to suggest that the patient has an intact primary visual pathway and auditory pathway and some sensory and primary motor pathway, she has no behaviours indicating any awareness of her own state or environment. (d) She is in a vegetative state. (e) This was caused by the brain damage sustained between 11th and16th January 2007 . (f) There is no need to undertake further specialised assessment beyond the WHIM assessment already undertaken. (g) There is no prospect whatsoever of recovery or improvement. She is in a permanent vegetative state. (h) Her life expectancy is probably around five years. (i) I support the clinical decision that it is not in the best interests of the patient to have continuing artificial nutrition and hydration as a medical treatment and that the existing tube should be removed. (j) Upon removal of artificial nutrition and hydration, it is likely that the patient will die within ten to fourteen days though it may be longer. (k) During that process the patient should have available to her all and any palliative care required with analgesia if necessary to manage any apparent distress.”
“The patient has been observed routinely and informally by staff and formally using a recognised structured assessment procedure [the WHIM procedure] over eight years and on a number of occasions. At no point has any person seen any behaviour even slightly suggestive of a low level of awareness. The chance of her having awareness in this situation is vanishingly small. Undertaking further assessments of her level of awareness would delay matters and no realistic prospect of identifying awareness.”
“Clinically, there is no doubt about the patient’s level of awareness. She is currently completely unaware of herself and her environment and there is no doubt that she has sufficient brain damage to account for this situation, although the precise cause of the deterioration after admission in hospital is not known absolutely. There is no doubt that her current clinical state is not due to any reversible factors, but in my opinion there is little doubt that she would not wish to be in this. Consequently, in my opinion, it is not in her best interests even to continue with hydration and it is certainly not in her best interests to re-establish clinically assisted nutrition and hydration.”
