“(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.”
“18. First, a person must be assumed to have capacity unless it is established that she lacks capacity: s. 1(2). The burden of proof therefore lies on the party asserting that P does not have capacity. In this case, therefore, the burden of proof lies on CC to prove that KK lacks capacity. The standard of proof is the balance of probabilities: s. 2(4). 19. Secondly, the Act provides that 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 disturbance in the functioning of, the mind or brain: s. 2(1). Thus the test for capacity involves two stages. The first stage, sometimes called the ‘diagnostic test’, is whether the person has such an impairment or disturbance. The second stage, sometimes known as the ‘functional test’, is whether the impairment or disturbance renders the person unable to make the decision. S. 3(1) provides that, for the purposes of s. 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. Important guidance as to the assessment of capacity generally, and the interpretation and application of the four components of the functional test in particular, is set out in Chapter 4 of theMental Capacity Act 2005 Code of Practice. 20. Third, capacity is both issue-specific and time specific. A person may have capacity in respect of certain matters but not in relation to other matters. Equally, a person may have capacity at one time and not at another. The question is whether at the date on which the court is considering the question whether the person lacks capacity in question, in this case to make decisions as to her residence and care. 21. Fourthly, a person is not to be treated as unable to make a decision unless all practicable steps to help her to do so have been taken without success: s.1(3). The Code of Practice stresses that ‘it is important not to assess someone's understanding before they have been given relevant information about a decision’ (para 4.16). Relevant information is said in paragraph 4.19 to include ‘what the likely consequences of a decision would be (the possible effects of deciding one way or another) – and also the likely consequences of making no decision at all’. Paragraph 4.46 of the Code of Practice adds that ‘it is important to assess people when they are in the best state to make the decision, if possible’. 22. Fifth, I bear in mind and adopt the important observations of Macur J in LBL v RYJ[2010] EWHC 2664 (Fam) (at para.24), that ‘it is not necessary for the person to comprehend every detail of the issue … it is not always necessary for a person to comprehend all peripheral detail …’ At paragraph 58 of the judgment, Macur J identified the question as being whether the person under review can ‘comprehend and weigh the salient details relevant to the decision to be made’. A further point – to my mind of particular importance in the present case – was also made by Macur J at paragraph 24 in that judgment: ‘…it is recognised that different individuals may give different weight to different factors’. 23. Sixth, a person is not to be treated as unable to make a decision merely because she makes an unwise decision: s. 1(4). Paragraph 4.30 of the Code of Practice states: ‘It is important to acknowledge the difference between unwise decisions … and decisions based on a lack of understanding of risks or inability to weigh up the information about a decision. Information about decisions the person has made based on a lack of understanding of risks or inability to weigh up the information can form part of a capacity assessment – particularly if someone repeatedly makes decisions that put them at risk or result in harm to them or someone else’. 24. Finally, in assessing the question of capacity, the court must consider all the relevant evidence. Clearly, the opinion of an independently-instructed expert will be likely to be of very considerable importance, but in addition the court in these cases will invariably have evidence from other clinicians and professionals who have experience of treating and working with P, the subject of the proceedings. Often there will be evidence from family and friends of P. Occasionally, as in this case, there will be direct evidence from P herself. In A County Council v KDand L[2005] EWHC 144 (Fam) [2005] 1 FLR 851 at paras 39 and 44, Charles J observed ‘it is important to remember (i) that the roles of the court and the expert are distinct and (ii) it is the court that is in the position to weigh the expert evidence against its findings on the other evidence… the judge must always remember that he or she is the person who makes the final decision’. That case concerned an application for a care order underPart IV of the Children Act 1989 , but the principles plainly apply to proceedings under the Mental Capacity Act in general and the assessment of the functional test under s. 2 in particular. In other words, when assessing the ability of P to (a) understand the information relevant to the decision (b) retain that information, and (c) use or weigh that information as part of the process of making the decision, the court must consider all the evidence, not merely the views of the independent expert. In many cases, perhaps most cases, the opinion of the expert will be confirmed by the other evidence, but inevitably there will be cases where the court reaches a different conclusion. When taking evidence from P herself, the court must plainly be careful about assessing the capacity to understand, retain and use and weigh up information, but, whilst acknowledging the important role for expert evidence, the assessment is ultimately a matter for the court. 25. There is a further point, to which I alluded in an earlier decision in PH v A Local Authority, Z Ltd and R[2011] EWHC 1704 (Fam) . In assessing the evidence, the court must be aware of the difficulties which may arise as a result of the close professional relationship between the clinicians and professionals treating and working with, P. In PH, I drew attention to a potential risk, identified by Ryder J in Oldham MBC v GW and PW [2007] EWHC136 (Fam)[2007] 2 FLR 597 , another case brought underPart IV of the Children Act 1989 , that the professionals and the court may be unduly influenced by what Ryder J called the ‘child protection imperative’, meaning ‘the need to protect a vulnerable child’ that, for perfectly understandable reasons, may influence the thinking of professionals involved in caring for the child. Equally, in cases of vulnerable adults, there is a risk that all professionals involved with treating and helping that person – including, of course, a judge in the Court of Protection – may feel drawn towards an outcome that is more protective of the adult and thus, in certain circumstances, fail to carry out an assessment of capacity that is detached and objective. On the other hand, the court must be equally careful not to be influenced by sympathy for a person’s wholly understandable wish to return home.”
