Those who cannot consent

This provides that care or treatment can go ahead after all, if it is in the best interest of the patient. However, when medical treatment is no longer in the best interests of the patient, then no medical care is allowed and must be withdrawn (Airedale Trust v Bland). Also, if a patient, who is mentally competent, refuses to consent, that is the end of the matter and the treatment cannot proceed as doing so would be a battery. Even if it puts at risk the life of the patient's unborn child (St George's Healthcare NHS Trust v S). And even if it risks the patient's own death (Re B).
