“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.”
'Best interests is not a test of "substituted judgement" (what the person would have wanted), but rather it requires a determination to be made by applying an objective test as to what would be in the person's best interests.' [38] I agree. It follows from this, in my judgment, that the guidance given under the Mental Health Acts 1959 and 1983 about the making of settlements or wills can no longer be directly applied to a decision being made under the 2005 Act. I say this for a number of reasons: (i) The 2005 Act does not require the counterfactual assumption that P is not mentally disordered. The facts must be taken as they are. It is not therefore necessary to go through the mental gymnastics of imagining that P has a brief lucid interval and then relapses into his former state. (ii) The goal of the inquiry is not what P 'might be expected' to have done; but what is in P's best interests. This is more akin to the 'balance sheet' approach than to the 'substituted judgment' approach. The code of practice makes this clear in that it points out that the test of best interests was one that was worked out by the courts mainly in decisions relating to the provision of medical care: para 5.1. (iii) The previous guidance was concerned with deciding what P would have wanted if he were not mentally disordered. But the 2005 Act requires the decision-maker to consider P's present wishes and feelings, which ex hypothesi are wishes and feelings entertained by a person who lacks mental capacity in relation to the decision being made on his behalf. (iv) The same structured decision-making process applies to all decisions to be made on P's behalf, whether great or small, whereas the previous guidance was specific to the making of a will, gift or settlement. Moreover, it is a decision-making process which must be followed, not only by the court, but by anyone who takes decisions on P's behalf. (v) In making his decision the decision-maker must consider 'all relevant circumstances'. (vi) The Act expressly directs the decision-maker to take a number of steps before reaching a decision. These include encouraging P to participate in the decision. He must also 'consider'
'55. In my judgment it is the inescapable conclusion from the stress laid on these matters in the Act that the views and wishes of P in regard to decisions made on his behalf are to carry great weight. What, after all, is the point of taking great trouble to ascertain or deduce P's views, and to encourage P to be involved in the decision-making process, unless the objective is to try to achieve the outcome which P wants or prefers, even if he does not have the capacity to achieve it for himself? 56. The Act does not of course say that P's wishes are to be paramount, nor does it lay down any express presumption in favour of implementing them if they can be ascertained. Indeed the paramount objective is that of P's best interests. However, by giving such prominence to the above matters, the Act does in my judgment recognise that having his views and wishes taken into account and respected is a very significant aspect of P's best interests. Due regard should therefore be paid … when doing the weighing exercise of determining what is in P's best interests in all the circumstances of the case. 57. As to how this will work in practice, in my judgment, where P can and does express a wish or view which is not irrational (in the sense of being a wish which a person of full capacity might reasonably have), is not impracticable as far as its physical implementation is concerned, and is not irresponsible having regard to the extent of P's resources (ie whether a responsible person of full capacity who had such resources might reasonably consider it worth using the necessary resources to implement his wish) then that situation carries great weight, and effectively gives rise to a presumption in favour of implementing those wishes, unless there is some potential sufficiently detrimental effect for P of doing so which outweighs this. 58. That might be some extraneous consequence, or some other unforeseen, unknown or unappreciated factor. Whether this further consideration actually should justify overriding P's wishes might then be tested by asking whether, had he known of this further consideration, it appears (from what is known of P) that he would have changed his wishes. It might further be tested by asking whether the seriousness of this countervailing factor in terms of detriment to P is such that it must outweigh the detriment to an adult of having one's wishes overruled, and the sense of impotence, and the frustration and anger, which living with that awareness (in so far as P appreciates it) will cause to P. Given the policy of the Act to empower people to make their own decisions wherever possible, justification for overruling P and "saving him from himself" must, in my judgment, be strong and cogent. Otherwise, taking a different course from that which P wishes would be likely to infringe the statutory direction in s [1(6)] of the Act, that one must achieve any desired objective by the route which least restricts P's own rights and freedom of actions.' [41] I agree with the broad thrust of this, although I think that Judge Marshall QC may have slightly overstated the importance to be given to P's wishes. First, s 1(6) is not a statutory direction that one 'must achieve' any desired objective by the least restrictive route. Section 1(6) only requires that before a decision is made 'regard must be had' to that question. It is an important question, to be sure, but it is not determinative. The only imperative is that the decision must be made in P's best interests. Second, although P's wishes must be given weight, if, as I think, Parliament has endorsed the 'balance sheet' approach, they are only one part of the balance. I agree that those wishes are to be given great weight, but I would prefer not to speak in terms of presumptions. Third, any attempt to test a decision by reference to what P would hypothetically have done or wanted runs the risk of amounting to a 'substituted judgment' rather than a decision of what would be in P's best interests. But despite this risk, the Act itself requires some hypothesising. The decision-maker must consider the beliefs and values that would be likely to influence P's decision if he had capacity and also the other factors that P would be likely to consider if he were able to do so. This does not, I think, necessarily require those to be given effect. As the Code of Practice issued by the Lord Chancellor on23 April 2007 explains (para 5.38): '
