“(2). A person must be assumed to have capacity unless it is established that he lacks capacity. (3). A person is not to be treated as unable to make a decision unless all practicable steps to help him to do so have been taken without success. (4). A person is not to be treated as unable to make a decision merely because he makes an unwise decision.”
“(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). It does not matter whether the impairment or disturbance is permanent or temporary. (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.”
