Challenging the core of legal doctrine: negotiating the ‘supported’ decision making paradigm

With few exceptions, a person’s right to make and act on a decision in jurisdictions such as New Zealand depends upon them possessing certain functional abilities, commonly referred to as mental capacity. However, an emerging human rights discourse rejects the orthodox approach in favour of a support-based paradigm that is premised upon two distinct but related concepts: “universal legal capacity” and “supported decision making”. On this account, every adult person retains the right to exercise legal agency regardless of mental status, although some individuals will require active and potentially significant support to do so.  Importantly, the United Nations Convention on the Rights of Persons with Disabilities (CRPD) in conjunction with the subsequent General Comment (GC) of the Committee on the Rights of Persons with Disabilities, has endorsed this alternative support-based model in international law.  While the support paradigm has much to offer a rights-based society, it also presents a radical challenge to established legal doctrine.  This presentation identifies two particularly challenging areas implicated by the support paradigm, and considers the extent to which existing health care law may be interpreted consistently with the emerging supported decision-making paradigm.

About the Association

The Australasian Association of Bioethics and Health Law (AABHL) was formed in 2009.

It encourages open discussion and debate on a range of bioethical issues, providing a place where people can ask difficult questions about ideas and practices associated with health and illness, biomedical research and human values.

The AABHL seeks to foster a distinctive Australasian voice in bioethics, and provide opportunities for international engagement through its membership, journal and conferences.

Members come from all the contributing humanities, social science and science disciplines that make up contemporary bioethics.

Many members have cross-disciplinary interests and all seek to broaden the dialogues in which all members of the wider community ultimately have an interest.

The AABHL is a supportive, creative and challenging community that provides a rich source of continuing academic refreshment and renewal.
