Recent history of erratic behaviour and significant paranoid beliefs linking her relationship breakup with the death of [redacted]. Reported to be running around in her pyjamas, talking to complete strangers about her fears of being murdered, beliefs that her phone is being tampered with by her ex-partner and her best friend.
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 patient is severely frightened and highly stressed from her persecutory delusions and bizarre thinking. She is extremely vulnerable because of her paranoia. Further, [the patient's] mental health will deteriorate if immediate treatment is not commenced. > > Paranoid symptoms and elevated mood place the patient at risk of being exploited by others, and reputational damage.
Section 40(c) - Appropriate and effective treatment
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) assess a person's mental state. > > (2) However, this professional intervention does not extend to - > > (a) special psychiatric treatment; or > > (b) a termination of pregnancy; or > > (c) a procedure that could render a person permanently infertile; or > > (d) the removal, for transplantation, of human tissue that cannot thereafter be replaced by natural processes of growth or repair; or > > (e) general health care. > > (3) For the purposes of this Act, treatment does not include seclusion, chemical restraint, mechanical restraint or physical restraint.
Although s 40(c) uses the words "the treatment will be appropriate and effective", it is clear that the legislation is intended to apply to mentally ill individuals whose symptoms cannot be treated or ameliorated in any way. For the purposes of s 40(c) treatment will be "appropriate and effective" if it is treatment directed towards the management of the ill effects of mental illness, or even just the monitoring of a person's mental state: s 6(1)(b) and (d).
It is proposed to commence a trial of oral antipsychotic medication with consideration of switching to depo medication, given her lack of insight and strong opposition to receiving any treatment.
Section 40(d) - The treatment requires an order
[the patient] does not accept that she has a mental illness and is strongly opposed to any psychiatric treatment.
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). > > (2) For the purposes of this Act, a child is taken to have the capacity to make a decision about his or her own assessment or treatment (decision-making capacity) only if a person or body considering that capacity under this Act is satisfied that - > > (a) the child is sufficiently mature to make the decision; and > > (b) notwithstanding any impairment of, or disturbance in, the functioning of the child's mind or brain, the child is able to - > > (i) understand information relevant to the decision; and > > (ii) retain information relevant to the decision; and > > (iii) use or weigh information relevant to the decision; and > > (iv) communicate the decision (whether by speech, gesture or other means). > > (3) For the purposes of this section - > > (a) an adult or child may be taken to understand information relevant to a decision if it reasonably appears that he or she is able to understand an explanation of the nature and consequences of the decision given in a way that is appropriate to his or her circumstances (whether by words, signs or other means); and > > (b) an adult or child may be taken to be able to retain information relevant to a decision even if he or she may only be able to retain the information briefly. > > (4) In this section - > > information relevant to a decision includes information on the consequences of - > > (a) making the decision one way or the other; and > > (b) deferring the making of the decision; and > > (c) failing to make the decision.
...we agree that the threshold of capacity under the Act is a relatively low one. It only requires a person to be able to understand, retain and use or weigh the information and communicate a decision in the terms of the general nature, purpose and effect of the treatment. There is not a requirement that a person has a high level of understanding at a level similar to that of their treating team. > > With respect to capacity, we acknowledge that a lack of insight into the diagnosis alone is not sufficient to conclude that a person lacks decision-making capacity. Instead, a lack of capacity is a factual issue that can be relevant in evaluating a person's ability to understand, retain, and use or weigh the relevant information, which may support a determination of incapacity. > > However, we are challenged by the concept that a person who cannot recognise that they have a mental illness and recognise the symptoms of that illness due to an impairment in the function of their mind or brain can still have decision making capacity. This is because they cannot understand how the information is relevant to them and so cannot weigh up or use the information to reach a decision in the abstract.
[the patient's] mental health will deteriorate if immediate treatment is not commenced. For that reason, and the reasons outlined earlier, I am satisfied that without treatment there is currently a likelihood of serious risk to the patient's health and safety, and the safety of others. If the assessment order were to lapse without an ITO in place, then the patient may discharge herself as she would be entitled to do.
(a) Antipsychotic medication > > (b) Mood stabilising > > (c) Antidepressant medication > > (d) Benzodiazepine medication > > (e) Anticholinergic medication for treatment of any extrapyramidal side effects from taking antipsychotic mediation.
Medications may be administered orally and/or by intra-muscular injection and/or by depot injection as prescribed by a treating psychiatrist within clinical guidelines, with dosages adjusted according to clinical response and tolerability.
