8D: FURTHER FEATURES OF THE MENTAL CAPACITY ACT

  1. In addition, there are a number of areas that have been touched on in this report but require closer scrutiny in a future review of the law.
  • Register for enduring powers of attorney (EPOAs): There is no transparent mechanism in New Zealand to ensure oversight of attorneys appointed under an enduring power of attorney (EPOA). The 2007 amendments, which purported to address ongoing problems of misuses and abuse of EPOAs in New Zealand, have failed to provide a solution. A key factor promoting the success of the English model is the fact that there is a national register of enduring powers of attorney (referred to as LPAs), supported by a public agency, with the objective of ensuring more effective supervision of attorneys acting under EPOAs. It is now recognised in the UK that measures under existing mental capacity legislation, such as EPOAs and advance directives, should be utilised for their potential as instruments of support for the exercise of legal agency as contemplated by art 12(3), with accompanying safeguards under art 12(4), of the CRPD.920 The establishment of a register to facilitate these measures, and associated safeguards that would accompany it, is an essential reform for New Zealand. It could be cost-effective, self-funded, and efficient through the use of an electronic register.

  • Advance directives: As with EPOAs, advance directives are an important expression of a person’s prior autonomy – as they are an advance direction made when a person is still capable, to refuse specified medical treatment for a time in the future when they may lack capacity to consent to or refuse treatment. In New Zealand, there is no mandated form for an advance directive. Right 7(5) of the HDC Code provides: “Every consumer may use an advance directive in accordance with the common law,” but it does not tell us what the common law rules are. Under the PPPR Act, there is a confused relationship between EPOAs and advance directives. Where an attorney has been appointed under the PPPR Act, they must consult the person for whom they act. However, the paramount consideration for the attorney in these circumstances is to act in the person’s best interests, and the attorney might, on occasion, consider this requires them to act contrary to the person’s own prior instructions contained in an advance directive.921  New Zealand law gives no clear indication as to whose views should prevail. The MCA, in contrast, has a clearly mandated framework for creating valid and applicable advance directives which state the circumstances in which a specified treatment either should, or should not, be carried out.922  This clarifies the circumstances in which the advance directive is to prevail. These developments could encourage people to make advance directives for when they lose capacity for decision- making for a range of decisions. All advance directives and EPOAs could be included on one electronic register, so they can be readily known.923

  • Oversight and monitoring by a public body: In England, the MCA established the Office of the Public Guardian (OPG). This is an executive agency of the Ministry of Justice. Its aim is to help make sure that adults who lack capacity to make decisions for themselves are protected from abuse. The functions of the Public Guardian fall into three categories: establishing and maintaining a register of LPAs (EPOAs); supervising deputies (welfare guardians or property managers) appointed by the court; and investigations – referred to as “safeguarding referrals”. The Public Guardian’s office can also provide a professional deputy (the equivalent of a welfare guardian) who can be appointed by the Court under the MCA. This kind of arrangement would go some way to assist with the shortage of independent welfare guardians available in New Zealand. Such a public body could also provide oversight of the legislation and its proposed Code of Practice.

  • Independent advocates: New Zealand currently has no provision for the appointment of an independent advocate for adults with impaired capacity when serious medical treatment decisions need to be made or when they are deprived of their liberty. While there are health and disability advocates, they are largely concerned with complaints under the HDC Code. In England, the MCA has created an independent mental capacity advocate service (IMCA). This service is designed to help vulnerable people who lack the capacity to make such important decisions and who have no family or friends that it would be appropriate to consult. Recent law reform reports in the UK have emphasised that compliance with the CRPD requires that statutory advocacy services should be funded at a level that ensures genuine and effective access to independent advocates by persons with disabilities in any matter that impact upon their ability to exercise legal capacity.924 
  1. It is said that the measure of a society is how well the most vulnerable are treated.925 The PPPR Act is overdue for revision in line with contemporary thinking about the law for protecting and promoting the rights of people with impaired capacity for decision-making. The mental capacity law landscape in New Zealand is fragmented. A review of the law will require a coordinated approach across the social, health and legal policy sectors. It will create the opportunity for New Zealand to show a firm commitment to human rights principles in its construction of capacity as a legal concept, and the chance to develop the law from New Zealand’s own cultural perspective. Such reform is urgently needed. It is likely to get full support from those working within the health and disability sector who want to make positive changes that will benefit people with impaired capacity for decision-making.

921 Protection of Personal and Property Rights Act 1988, s 99A(2). There are limits on the powers of an attorney, (as with welfare guardians under s 18) including preventing the attorney from refusing consent for standard medical treatment or procedures intended to save that person’s life or prevent serious damage to that person’s health: Protection of Personal and Property Rights Act 1988, s 18(1)(c).

922 Mental Capacity Act, ss 23-26.

923 The establishment of an electronic “health directive register” for EPOAs and advance directives could also include organ donations. See recent health policy consultation document about the need to increase organ donation in New Zealand. The proposal is that the Ministry of Health should establish a consistent mechanism whereby health professionals around New Zealand can obtain independent assurance that new practices and processes are ethically acceptable: Ministry of Health Increasing Rates of Deceased Organ Donation: Consultation document. Ministry of Health, Wellington, June 2016). It is important to note that the Human Tissue Act 2008 would not need to be amended to establish a register. The Act already has enabling provisions to establish regulations for a national organ and tissue donor “opt-on” register: Human Tissue Act, s 78. See A Douglass, “The new Human Tissue Act” (2008) NZMJ 377.
