‘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 a disturbance in the functioning of, the mind or brain.’
‘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 (whether by talking, using sign language or any other means).’
‘In the light of Dr Posser’s evidence, I am satisfied on balance that he lacks capacity to manage his own affairs. In so finding I acknowledge, as I have done in relation to the other matters, that there would be times when a snapshot of his condition would reveal an ability to manage his affairs. But the general concept of managing affairs is an ongoing act and, therefore, quite unlike the specific act of making a will or making an enduring power of attorney. The management of affairs relates to a continuous state of affairs whose demands may be unpredictable and may occasionally be urgent. In the context of the evidence that I have, I am not satisfied that he has capacity to manage his affairs.’
‘(3) He must consider – (a) whether it is likely that the person will at some time have capacity in relation to the matter in question, and (b) if it appears likely that he will, when that is likely to be. (6) He must consider, so far as is reasonably ascertainable – (a) the person's past and present wishes and feelings (and, in particular, any relevant written statement made by him when he had capacity), (b) the beliefs and values that would be likely to influence his decision if he had capacity, and (c) the other factors that he would be likely to consider if he were able to do so.’
