8A: PROVISIONS OF THE MCA THAT COULD BE INSERTED INTO THE PPPR ACT

  1. The PPPR Act is in need of review and the HDC Code is silent on the definition of the capacity or “competence” that a person requires to make an informed healthcare decisions. The recommendations below aim to inject more clarity into the key concepts governing decision- making for those with impaired capacity, notably, into the concepts of supported decision- making; capacity itself; and the notion of best interests as a standard governing decision- making for others. These recommendations concern:
  • Supported decision-making – a legal principle, taking into account tikanga Māori. The CRPD provides an opportunity to enhance and improve New Zealand’s adult guardianship law by giving priority to supported decision-making as a legal principle, including incorporation of tikanga Māori. There is a need for clear statutory guidance about who bears the responsibility, and when, to provide support to people whose decision-making ability is impaired, to enable them to make their own decisions whenever possible.

  • Defining capacity – a single test. As capacity or incapacity is the “brightline” for deciding whether the law permits intervention in people’s lives, it is essential that there is a clear test for it. There are currently several tests for incapacity in the PPPR Act and no definition of incapacity in the HDC Code for the purposes of determining whether a person can give informed consent or refusal to healthcare. Section 3 of the MCA provides a single legal test, whereby a person lacks capacity if they are unable to make a decision due to an inability to: understand information relevant to the decision, retain that information, use or weigh the information, or communicate the decision. This test is recommended for adoption in New Zealand.

  • Best interests – a standard for decision-making. The “best interests” standard recognises that where supported decision-making options have been exhausted, decisions by others need to be made. It can provide a transparent basis for decision- making when a person is unable to fully exercise their legal capacity. It is an essential complement to a supported decision-making framework: capacity is not an off-switch to a person’s rights and freedoms. In New Zealand the phrase “best interests” is found in both the PPPR Act and in Right 7(4) of the HDC Code, but it cannot be regarded as a specified legal standard for decision-making of the kind codified in the MCA. Section 4 of the MCA provides a checklist setting out a series of matters that must be considered when best interests decisions are made on behalf of a person by a substitute decision-maker. These include: the person with impaired capacity should participate as much as possible in the process of determining their best interests; their present and past wishes and feelings (or will and preferences) should be recognised; and so should the beliefs and values that would likely have influenced their decisions if they had capacity.
