“Powers to make decisions and appoint deputies: general (1) This section applies if a person (“P”) lacks capacity in relation to a matter or matters concerning– (a) P's personal welfare, or (b) P's property and affairs. (2) The court may– (a) by making an order, make the decision or decisions on P's behalf in relation to the matter or matters, or (b) appoint a person (a “deputy”) to make decisions on P's behalf in relation to the matter or matters. (3) The powers of the court under this section are subject to the provisions of this Act and, in particular, to sections 1 (the principles) and 4 (best interests). (4) When deciding whether it is in P's best interests to appoint a deputy, the court must have regard (in addition to the matters mentioned in section 4) to the principles that– (a) a decision by the court is to be preferred to the appointment of a deputy to make a decision, and (b) the powers conferred on a deputy should be as limited in scope and duration as is reasonably practicable in the circumstances.”
“Restrictions on deputies (1) A deputy does not have power to make a decision on behalf of P in relation to a matter if he knows or has reasonable grounds for believing that P has capacity in relation to the matter. (2) Nothing in section 16(5) or 17 permits a deputy to be given power— (a) to prohibit a named person from having contact with P; (b) to direct a person responsible for P's health care to allow a different person to take over that responsibility. (3) A deputy may not be given powers with respect to— (a )the settlement of any of P's property, whether for P's benefit or for the benefit of others, (b) the execution for P of a will, or (c) the exercise of any power (including a power to consent) vested in P whether beneficially or as trustee or otherwise. (4) A deputy may not be given power to make a decision on behalf of P which is inconsistent with a decision made, within the scope of his authority and in accordance with this Act, by the donee of a lasting power of attorney granted by P (or, if there is more than one donee, by any of them). (5) A deputy may not refuse consent to the carrying out or continuation of life-sustaining treatment in relation to P. (6) The authority conferred on a deputy is subject to the provisions of this Act and, in particular, sections 1 (the principles) and 4 (best interests). (7) A deputy may not do an act that is intended to restrain P unless four conditions are satisfied. (8) The first condition is that, in doing the act, the deputy is acting within the scope of an authority expressly conferred on him by the court. (9) The second is that P lacks, or the deputy reasonably believes that P lacks, capacity in relation to the matter in question. (10) The third is that the deputy reasonably believes that it is necessary to do the act in order to prevent harm to P. (11) The fourth is that the act is a proportionate response to— (a) the likelihood of P's suffering harm, (b) the seriousness of that harm. (12) For the purposes of this section, a deputy restrains P if he— (a) uses, or threatens to use, force to secure the doing of an act which P resists, or (b) restricts P's liberty of movement, whether or not P resists, or if he authorises another person to do any of those things.” or if he authorises another person to do any of those things.”
“57 The Act and Code are therefore constructed on the basis that the vast majority of decisions concerning incapacitated adults are taken informally and collaboratively by individuals or groups of people consulting and working together. It is emphatically not part of the scheme underpinning the Act that there should be one individual who as a matter of course is given a special legal status to make decisions about incapacitated persons. Experience has shown that working together is the best policy to ensure that incapacitated adults such as E receive the highest quality of care. … 61 It is axiomatic that the family is the cornerstone of our society and a person who lacks capacity should wherever possible be cared for by members of his natural family, provided that such a course is in his best interests and assuming that they are able and willing to take on what is often an enormous and challenging task. That does not, however, justify the appointment of family members as deputies simply because they are able and willing to serve in that capacity. The words of section 16(4) are clear. They do not permit the court to appoint deputies simply because “it feels confident it can” but only when satisfied that the circumstances and the decisions which will fall to be taken will be more appropriately taken by a deputy or deputies rather than by a court, bearing in mind the principle that decisions by the courts are to be preferred to decisions by deputies. Even then, the appointment must be as limited in scope and duration as is reasonably practicable in the circumstances. It would be a misreading of the structure and policy of the statute, and a misunderstanding of the concept and role of deputies, to think it necessary to appoint family members to that position in order to enable them better to fulfil their role as carers for P.”
