Following discharge [on 22 October 2024], [TKD] was referred for follow up with... the community team for management of her [bipolar affective disorder]. She was ambivalent regarding follow up, believing that she had fully recovered from her recent relapse. On review by a... psychiatrist in Jan 2025, she was found to have made good physical recovery but had only partial insight into the nature, severity and risks associated with her mental illness. At subsequent ...reviews TKD was repeatedly requesting cessation of her medication... despite explanation of risks of relapse of catatonia and mania. Cautious dose reduction occurred with recommendation for close monitoring by [the service]. In March 2025, evolving hypomania was evident, with a recommendation made for [medication changes]. [TKD's] adherence to medication and engagement with [the service] subsequently became increasingly erratic, resulting in worsening of her mental state. This was reflected in increased financial expenditure, plans to purchase properties (café, factory unit for her mother, a boatshed and property), failure to pay debts, escalating financial losses, repeated acrimonious interactions with care staff at the [residential aged care facility] in which her 92-year old mother lives, and law- breaking (driving an unregistered car).
40. Treatment criteria > > The treatment criteria in relation to a person are -
(a) the person has a mental illness; and
(b) without treatment, the mental illness will, or is likely to, seriously harm -
(i) the person's health or safety; or
(ii) the safety of other persons; and
(c) the treatment will be appropriate and effective in terms of the outcomes referred to in section 6(1); and
(d) the treatment cannot be adequately given except under a treatment order; and
(e) the person does not have decision-making capacity.
The person has a mental illness pursuant to s 40(a)
4. Meaning of mental illness > > (1) For the purposes of this Act -
(a) a person is taken to have a mental illness if he or she experiences, temporarily, repeatedly or continually -
(i) a serious impairment of thought (which may include delusions); or
(ii) a serious impairment of mood, volition, perception or cognition; and
(b) nothing prevents the serious or permanent physiological, biochemical or psychological effects of alcohol use or drug-taking from being regarded as an indication that a person has a mental illness.
Without treatment, the mental illness will, or is likely to, seriously harm the person's health or safety; or the safety of other persons pursuant to s 40(b)
The thresholds for the satisfaction of the criteria in s 40(b) and (c) are fairly low. To be satisfied as to (b), a medical practitioner need not be satisfied of any risk to other persons, nor of any risk to the safety of the patient. It is sufficient if the practitioner is satisfied that, without treatment, the mental illness is likely to seriously harm the person's health, which of course includes the person's mental health.
Section 40(b) is concerned with what is "likely". When that word is used in legislation, it can have various meanings. It can mean "more probable than not" or "more than a 50% chance". It can refer to something that might well happen. It can refer to a possibility that is more than a remote or theoretical possibility. The meaning of the word has been considered in a great many cases. See, for example, Boughey v The Queen (1986) 161 CLR 10; Tillmanns Butcheries Pty Ltd v Australasian Meat Industry Employees' Union [1979] FCA 85; (1979) 42 FLR 331 at 339; Cream Holdings Ltd v Banerjee [2003] EWCA Civ 103; [2003] 3 WLR 999. Much depends on the legislative context. It is significant that the principal purpose or object of s 40(b) is the protection of mentally ill persons and others from risks of harm. Having regard to the purpose and context of the provision, I consider that "likely" should be given a wide interpretation. It should not be interpreted as meaning "more probable than not". It must be interpreted as meaning something more than a remote or theoretical possibility. I think it should be interpreted as referring to something that might well happen. Having regard to the evidence that I have referred to, I consider that it was open to the Tribunal to conclude that, without treatment, the appellant's mental illness was "likely" to result in her killing herself.
The treatment will be appropriate and effective in terms of the outcomes referred to in s 6(1) pursuant to s 40(c)
6. Meaning of treatment > > (1) For the purposes of this Act, treatment is the professional intervention necessary to - > > (a) prevent or remedy mental illness; or > > (b) manage and alleviate, where possible, the ill effects of mental illness; or > > (c) reduce the risks that persons with mental illness may, on that account, pose to themselves or others; or > > (d) monitor or evaluate a person's mental state.
The treatment cannot be adequately given except under a treatment order pursuant to s 40(d)
The person does not have decision-making capacity pursuant to s 40(e)
7. Capacity of adults and children to make decisions about their own assessment and treatment > > (1) For the purposes of this Act, an adult is taken to have the capacity to make a decision about his or her own assessment or treatment (decision-making capacity) unless a person or body considering that capacity under this Act is satisfied that -
(a) he or she is unable to make the decision because of an impairment of, or disturbance in, the functioning of the mind or brain; and
(b) he or she is unable to -
(i) understand information relevant to the decision; or
(ii) retain information relevant to the decision; or
(iii) use or weigh information relevant to the decision; or
(iv) communicate the decision (whether by speech, gesture or other means).
