Understanding Legal Capacity and Consent in Australia
Under Australian law, every adult is presumed to have decision-making capacity unless proven otherwise. This means they have the legal right to decide where they live and what health care they receive, even if family or medical professionals believe those decisions are unwise. To provide valid consent, a person must understand and retain the relevant information, weigh the options and consequences, and communicate their decision freely and voluntarily. Forcing an elderly person into care without valid consent could constitute assault and result in civil or criminal liability.
The Legal Threshold: When Incapacity Changes Everything
If an elderly person is assessed as having lost their decision-making capacity due to a condition like dementia, severe mental illness, or a brain injury, the situation changes. In these circumstances, a substitute decision-maker can lawfully arrange residential aged care in the person's best interests, even if the person resists. However, a formal assessment of capacity is required by a qualified medical professional, often a geriatrician or psychiatrist. The assessment focuses on the person's ability to make the specific decision at that time, rather than their medical condition alone.
The Role of Substitute Decision-Makers
In Australia, there is a clear legal hierarchy for substitute decision-making when a person has lost capacity. These roles ensure that decisions are made with legal authority and in the person's best interests.
Enduring Power of Guardianship (EPG)
An Enduring Power of Guardianship is a legal document allowing a person with capacity to appoint a guardian to make health and lifestyle decisions on their behalf if they later lose capacity. This is a proactive planning tool that becomes legally binding upon loss of capacity. The appointed guardian must act in the person's best interests, considering their known preferences.
Tribunal-Appointed Guardians
If capacity is lost without an EPG, a state or territory tribunal (like NCAT or VCAT) can appoint a guardian. This often happens with family disputes or when no suitable person is available. A Public Guardian may be appointed as a 'guardian of last resort'. The tribunal defines the guardian's authority, which may include accommodation and medical decisions.
Alternatives to Residential Care
Exploring alternatives is vital before considering residential care, especially against someone's wishes. Australia offers various services to help older people stay home longer.
- Home Care Packages: Government-subsidised packages fund services like cleaning, meals, personal care, and transport to support home independence.
- Respite Care: Short stays in a facility can provide carer breaks and introduce the elderly person to residential care.
- Supported Decision-Making: Individuals with some impairment can often make decisions with support, such as simplified information or more time.
What to Do When a Loved One is Resisting Care
If an elderly person resists moving to care, focus on communication and mediation. Involving a trusted third party, like a doctor or an aged care advocate (e.g., from OPAN), can be helpful. Understanding their reasons, such as fear of losing independence or familiarity, is key to finding a respectful solution.
Comparison of Decision-Making Pathways
| Feature | Full Capacity (Consent) | No Capacity (Substitute Decision) |
|---|---|---|
| Decision-Maker | The elderly person themselves. | Appointed Enduring Guardian or Tribunal-Appointed Guardian. |
| Legal Basis | Fundamental right to self-determination and bodily integrity. | Power derived from a legally recognised instrument (EPG) or a court/tribunal order. |
| Consent Required? | Yes, absolutely. Treatment or placement without consent can be illegal. | Consent is given by the legally authorised substitute decision-maker. |
| Override Refusal? | No. A person with capacity can refuse care, even if others deem it unwise. | Yes, the substitute decision-maker can override resistance if it is in the person's best interests. |
| Best Interests | The person's own view of their best interests takes precedence, including their "dignity of risk". | The substitute decision-maker must act in the person's best interests, considering their known wishes and values. |
| Relevant Documents | No special documents required, though an Advance Care Directive can outline future preferences. | Enduring Power of Guardianship or Tribunal Guardianship Order. |
Conclusion
In Australia, an elderly person with decision-making capacity cannot be forced into care against their will. However, if capacity is lost, a legally appointed substitute decision-maker (Enduring Guardian or tribunal-appointed guardian) can make decisions about care in the person's best interests. This process requires a formal capacity assessment and should follow the exploration of alternatives. Planning ahead and seeking legal advice is recommended.
