Outcomes
ST lacks capacity to make decisions regarding her future medical treatment.
ST's inability to believe the medical prognosis prevents her from understanding, using, and weighing relevant information, thus failing the functional test. Her refusal to accept the prognosis is likely due to an impairment of, or disturbance in, the functioning of her mind or brain, stemming from the trauma of her illness and prolonged intensive care.
ST lacks capacity to litigate without a litigation friend.
Given the lack of subject matter capacity, litigation capacity is also lacking. Concerns exist regarding the instruction of ST's independent solicitor.
