“… (2) D is guilty of an offence if he ill-treats or wilfully neglects P (1) sub-section (2) applies if D (a) has the care of a person who lacks, or whom D reasonably believes to lack, capacity … (2) a person must be presumed to have capacity unless it is established that he lacks capacity.”
“(1) 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. (2) … (3) a lack of capacity cannot be established merely by reference to – (a) a person’s age or appearance, or (b) a condition of his, or an aspect of his behaviour, which might lead others to make unjustified assumptions about his capacity.”
“… there has been a whole sea change in the attitude of the law to persons whose mental capacity is impaired. The former approach was based on a stark division between those who had capacity to manage their own affairs, and those who did not. The former took their own decisions for better or worse, and the latter fell under a regime in which decisions were made for them, perhaps with a generous, and in some cases patronising, token nod to their feelings by asking them what they wanted, and then deciding what none the less was objectively “best” for them. … the statute now embodies the recognition that it is the basic right of any adult to be free to take and implement decisions affecting his own life and living, and that a person who lacks mental capacity should not be deprived of that right except in so far as is absolutely necessary in his best interests.”
