[UQP] appears to be presenting with worsening psychosis with disturbance in her thoughts and disturbance in her mood on the background diagnosis of delusional disorder. She has a disturbance in her thoughts, paranoid towards her family members, that they are against her in their efforts for her to receive help and misidentifies other family members as her children and has an ongoing belief that family members have been swapped with doubles. She is presenting with a disturbance in her mood with an inability to maintain her mood state.
First, in S v Mental Health Tribunal [2016] TASSC 34 at [22], his Honour held: > > 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. > > Subsequently, his Honour provided additional comments as to the interpretation of this criterion in the matter of B v Mental Health Tribunal [2020] TASSC 10 at [14]: > > 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.
Without immediate treatment under a treatment order, there is a risk to the self through misadventure and further deterioration. There is a risk that her relationships could lead to her losing custody of her child. There would be a potential increase in direct self-risk if this were to occur. There is a potential inadvertent risk to others due to the belief that others have been swapped.
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
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).
Current treatment is evidence based treatment for psychosis, and there has been past improvement and stability of [UQP]'s mental state when taking these prescribed treatments.
[UQP] lacks insight into her mental health issues and her capacity to take decisions for his (sic) treatments appears to be affected by this acute relapse. There is no less restrictive and safe way to manage his (sic) current presentation except under the mental health act (sic).
If [UQP] was made a voluntary patient, she would leave the hospital as she does not believe she is unwell and does not wish to take prescribed medications, she has recently attempted to leave the ward.
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).
(a) is authority for the patient to be admitted to and if necessary detained in an approved facility for the purposes of receiving treatment;
(b) authorises a combination of treatment settings and the admission or readmission of the patient to those settings, including treatment in the community; and
(c) authorises the following:
- The patient is to take the following medication (depending on clinical indication):
- Antipsychotic medication
- Benzodiazepine medication
- Anticholinergic medication for treatment of any extrapyramidal side effects from taking antipsychotic medication
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.
