General information, not legal advice.
Supreme Court of WA
2025-07-04
Palmer J
Original judgment source is linked above.
(a) the first respondent (the Public Advocate) is currently appointed as a limited guardian in respect of NXD to:
(i) make treatment decisions for her, subject to div 3 of pt 5 of the Guardianship and Administration Act;
(ii) determine the services to which she should have access; and
(iii) seek legal advice and representation on her behalf, and to advocate in relation to any police investigation, criminal charges or related proceedings; and
(b) the Second Respondent (the Public Trustee) has been appointed plenary administrator of NXD's personal estate.
The history of orders and review proceedings prior to 2023
NXD applies for a review by a single member in 2024
(a) incapable of looking after her own health and safety;
(b) unable to make reasonable judgments in respect of matters relating to her person; or
(c) in need of oversight, care or control in the interests of her own health and safety, or for the protection of others;[5] and
(d) in need of a guardian.[6]
(a) is unable, by reason of a mental disability, to make reasonable judgments in respect of matters relating to all or any part of their estate; and
(b) is in need of an administrator of their estate.
The Full Tribunal's reasons for making the orders made
In starting again and remaking the decision under review, we have had regard to all of the material that was before the original decision-maker. We've also had regard to the transcript of the hearing held by the original decision-maker. The other documents filed by any of the other parties since the original hearing and what was said at the hearing. Having taken all of that material into account, we are satisfied, firstly, in relation to the application regarding administration, that [NXD] suffers from a mental disability, that she lacks capacity to make complex decisions about her finances that are in her own best interests, and that that inability is due to her mental disability.
In relation to the application regarding guardianship, we are satisfied that [NXD] is incapable of looking after her own health and safety; is unable to make reasonable judgments in respect of matters relating to her person; and that she's in need of oversight, care and control in the interest of her own health and safety. We're also satisfied that there is a need for formal orders to be made for both guardianship and administration. Finally, we are satisfied that the Public Trustee should be granted plenary powers of administration in respect of her estate, and that the Public Advocate should be granted limited powers of guardianship as to medical treatment decisions, decisions as to which services she should receive, and to seek legal advice and representation on behalf of [NXD], and to advocate in relation to any police investigation or criminal charges or other proceedings.
Accordingly, while formal orders will be made, they will be of a considerably narrower focus than those made previously, in particular, we're satisfied that the guardian should not have the functions of making decisions in relation to where and with whom [NXD] should live, or whether or not [NXD] should be subject to restrictive practices and restraints.
(a) NXD is incapable of making reasonable decisions in her own best interests;
(b) NXD has a mental disability; and
(c) NXD's incapacity is due to or because of that mental disability.
(a) NXD did not demonstrate sufficient capacity to make informed and well-reasoned decisions regarding her health;
(b) NXD's ability to understand and appreciate her functional impairments was limited, and would likely impair her ability to make informed and well-reasoned decisions regarding lifestyle matters should her situation require change;
(c) although Ms Parsons had little opportunity to question NXD regarding her financial decision-making capacity, Ms Parsons referred to statements made by NXD that appeared to have no basis in fact, and to evidence that prior to the administration orders being made, she was managing her finances 'quite poorly'; and
(d) Ms Parsons opined that continuing the 'current arrangement' of an administrator would be in her best interests.
(a) outside of mild difficulties across memory, visual-spatial processing and processing speed, NXD demonstrated more prominent difficulties on tasks requiring rapid mental flexibility and response inhibition;
(b) NXD occasionally struggled to plan and strategize to support her performance on tasks; and
(c) these weaknesses are indicative of executive functioning difficulties.
(a) expressed concern about NXD's ability to manage her finances and that NXD struggle to maintain her finances to the extent that she needed support from the Salvation Army;
(b) while this reflected a degree of problem-solving capacity, it also reflected a limited financial planning capacity on a day‑to‑day basis and was consistent with neuropsychological results of impairment in strategizing and planning; and
(c) this was the primary reason she had concerns about NXD's ability to manage complex financial decisions.
(a) although the history given by NXD did not suggest that she lacked the capacity to make decisions about her health care needs, the lack of acknowledgement of previous alcohol related harms would seem consistent with the Tribunal's observations of lack of insight;
(b) she was concerned about the absence of candidates NXD had in mind for guardian and administrator should she lose capacity which Dr Lee considered was consistent with lack of insight and consistent with the executive function impairment notes on psychological testing; and
(c) the absence of collateral information to support NXD's guardianship, the documentation of past concerns, alongside the lack of insight meant that Dr Lee felt unable to form an opinion to support the removal of the guardian on the information available.
(a) he gave evidence in person, whereas Dr Graham did not;
(b) NXD did not disagree with the evidence given by the delegated guardian; and
(c) it assumed that Dr Graham's letter reflected NXD's version of events, and that her version of events was the only version given to Dr Graham. It said that that would be consistent with her other behaviour in limiting information to other medical practitioners.
(a) Dr Lee's opinion was that NXD lacked the capacity to make reasonable decisions in her own best interests about complex financial matters, legal matters and medical treatment matters, but she was unsure about accommodation and services; and
(b) Dr Grant considered that NXD lacked capacity to make reasonable decisions in her own best interests about complex financial matters and the services that she should accept, but was unsure about legal matters, accommodation, medical treatment, although in relation to legal matters and accommodation, he deferred to Dr Lee.
(a) that the Tribunal -
(i) made an error of law or fact, or of both law and fact; or
(ii) acted without or in excess of jurisdiction, or did both of those things; or
(b) that there is some other reason that is sufficient to justify a review of the determination.
(a) it is in the interests of justice to do so; and
(b) sufficient notice that the appeal may be so determined has been given to such persons as, in the opinion of the Court, ought to have such notice.
There are a number of ways in which a factual finding may be vitiated by an error of law. For example, the decision-maker may misidentify the relevant legal test to be applied; the decision-maker may misapply the correct test; there may be no evidence to support the finding of fact, ie the finding of fact may not be open on the evidence; or the decision-maker may adopt a manner of decision-making which fails to discharge its obligations according to law. A contest as to whether a factual finding is vitiated in one of these ways requires an evaluation of the fact-finding process of the decision-maker to decide on its legality. The contest is not concerned with the merits of the factual finding; it is instead concerned with whether the decision-maker has acted lawfully and with authority.
In Haritos the Full Court held that it may be an error of law to make a decision which is irrational, illogical and not based upon findings or inferences of fact supported by logical grounds.
Haritos, in turn, relied on two High Court decisions concerned with judicial review for jurisdictional error - Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S20/2002 and Minister for Immigration and Citizenship v SZMDS. In SZMDS Crennan and Bell JJ explained the availability and scope of illogicality and irrationality as a basis for judicial review of a decision as to a jurisdictional fact:
What was involved here was an issue of jurisdictional fact upon which different minds might reach different conclusions. The complaint of illogicality or irrationality was said to lie in the process of reasoning. But, the test for illogicality or irrationality must be to ask whether logical or rational or reasonable minds might adopt different reasoning or might differ in any decision or finding to be made on evidence upon which the decision is based. If probative evidence can give rise to different processes of reasoning and if logical or rational or reasonable minds might differ in respect of the conclusions to be drawn from that evidence, a decision cannot be said by a reviewing court to be illogical or irrational or unreasonable, simply because one conclusion has been preferred to another possible conclusion.
Crennan and Bell JJ later explained that the correct approach was to ask whether it was open to engage in the process of reasoning in which the decision-maker engaged and to make the findings that the decision‑maker made on the material before it. Accordingly, it suffices if the decision-maker's reasoning process and relevant conclusion is justifiable.
In these respects, illogicality or irrationality mean something more than emphatic disagreement with the decision. Crennan and Bell JJ were at pains to make it clear that nothing in their reasons in SZMDS sanctioned the deployment of the grounds of 'illogicality' or 'irrationality' in decision-making to achieve merits review. It is also as well to recall the caution expressed by Allsop J (as his Honour was then) in Minister for Immigration and Multicultural and Indigenous Affairs v NBDS as to when an illogical or irrational approach to fact‑finding might reveal jurisdictional error:
What is plain, though, is that the demonstrating of one illogical aspect of fact finding in a wider scheme of factual analysis will rarely betray such a failure to attend to the jurisdictional task as to call in aid, for instance, what Gleeson CJ said in [Applicant S20/2002]. In such cases, all one has really done, at best, is demonstrate how an error of fact came to be made. Generally, such errors will be within jurisdiction.
A decision that is merely contestable is not illogical or irrational in the required sense. Nor can it suffice to establish some faulty inference of fact. The Full Court of the Federal Court has stated that 'extreme' illogicality must be demonstrated measured against the standard that it is not enough for the relevant question of fact to be one on which reasonable minds may come to different conclusions. In this context the words 'illogical' and 'irrational' are used with their proper meaning of devoid of, or contrary to, logic; or ignorant or negligent of, and not in conformity with, the laws of correct reasoning. The decision-maker's grounds for the impugned finding must reach the level of being 'arbitrary' or 'perverse'.
A finding that a determination is illogical, irrational and not based on findings or inferences of fact supported by logical grounds is not made lightly. As is also confirmed in the passage from NBDS reproduced at [76] above, not every lapse in logic will give rise to illogicality or irrationality of the requisite kind. But in seeking judicial relief based on illogicality or irrationality it does not need to be established that the decision would have been different but for the lack of reasoning; it is sufficient if the decision may have been different.

The further evidence that NXD sought to rely upon
... document also alleges that Dr Lee had not taken into account an Addenbrooke's Cognitive Assessment undertaken on 16 September 2024 for which she scored 93 out of 100. As [NXD] says, such a score is well within the normal range. But the allegation against Dr Lee is not true. On page 6 of her report, Dr Lee expressly refers to the Addenbrooke's Cognitive Assessment, and consistent with [NXD's] assessment, says that the result is "well within normal range". Despite that, Dr Lee reached the conclusions to which we have referred above.
The second was her Addenbrooke's capacity assessment. As we have noted above, that test recorded a score well within the normal range, and [NXD] is right to ask us to give weight to that testing. But such a test can never be conclusive, and indeed Dr Lee had regard to that test and yet remained of the view, as we've previously noted, that [NXD] lacked capacity in a couple of key areas.
FINDINGS
There is mildly decrease activity seen in both parietal and both frontal lobes. Preserved activity within the occipital lobes, cerebellum and brainstem. Reserved activity within the thalami and basal ganglia.
Statistical parametric mapping performed with the Neurostat program. There are no statistically significant decreased areas of metabolism.
Low-dose non-contrast CT shows generalised cerebral atrophy. The ventricles and sulci are proportional.
COMMENT
There [sic] no statistically significant deceased area of hypometabolism to indicate a specific neurodegenerative syndrome.
(emphasis added)
Neuroimaging alongside neuropsychology testing at first impression do not show gross abnormalities to suggest neurodegenerative disorder. However, the neuropsychological test details executive dysfunction of unclear cause - a cognitive function vital in managing complex tasks like complex financial matters. I do note however that the tests performed were not necessarily directed at testing for capacity but rather return to working as a lawyer. Nonetheless, the level of cognitive function required would likely be similar. This would be consistent with the hypo metabolism observed on PET scan in the frontal and parietal regions. In my opinion, there is organic evidence suggestive of executive dysfunction.
The document titled Medical Certificate and dated 28 May 2024 has also been filed. It's signed by general practitioner, Dr Shereen Awadalla, and her name is in the same font as the first line which says that [NXD] attended the Floreat Forum General Practice on that date. What follows is in different font and is poorly phrased. So, for example, and I quote:
[NXD] believed that she has the capacity to make business decision, looking after herself and vote.
New sentence:
She said she had done her house renovations decision 2021 for over two years.
New sentence:
She believed that she can made a decision for her one-fifth share for the Claremont Medical Centre rather than paid.
There is then in the purported medical certificate reference to a brain scan. In a different font again it then says, and I quote:
From previous test results looks that she has not had a serious condition to stop her manage her life -
one word "herlife" -
by herself.
We are very sceptical that this document is what it purports to be. Rather, it would appear that a medical certificate, as in a document used to obtain time off work, has been altered so as to contain material favourable to [NXD's] preferred view of her own capacity. It is unclear who altered the document, but we give no weight to it, given that Dr Awadalla has not otherwise provided an explanation for those unusual and unexplained apparent changes to the document.
(emphasis added)
The third matter relied upon by [NXD] was a letter dated 3 December 2024 from Dr Graham, who operated on her shoulder in August 2024. In that letter Dr Graham describes [NXD] as "a model patient, attending all her appointments on time and following all post-operative restrictions and recommendations to the letter". He goes on to say that he was not "initially aware of her being under a guardianship order; however, the doctor's impression is that she managed her shoulder condition extremely well independently".
The difficulty for [NXD] in this regard is that the delegated guardian gave evidence, as we've just adverted to, that when Dr Graham became aware that [NXD] was under a guardianship order, he agreed to undertake the surgery only on condition that she have appropriate supports post‑surgery, and secondly, that [NXD] refused to allow those supports to assist her. In our view, it's significant in circumstances where [NXD] has been very quick to criticise and correct - including during the hearing - what she sees as factual inaccuracies, that she did not do so when she was given the opportunity to respond to the delegated guardian's evidence as just described.
Dr Graham's letter is inconsistent with the evidence of the delegated guardian as to [NXD's] post-surgery restrictions and recommendations. Dr Graham's letter says that [NXD] followed them, and the delegated guardian says she did not. In this regard, we note that the letter from Dr Graham is dated 3 December 2024 and is unsigned, but rather contains the words quote "AI generated letter" in the signature area.
We are minded to prefer the evidence of the delegated guardian in this regard because he gave evidence in person, whereas Dr Graham did not; secondly, because [NXD] did not disagree with the evidence given by the delegated guardian; and thirdly, because we assume Dr Graham's letter reflects [NXD's] version of events, and that her version of events was the only version given to Dr Graham. That would be consistent with her other behaviour in limiting information to other medical practitioners. We accept in this regard that [NXD] appears to have identified the need for treatment for her shoulder and arranged appointments with the surgeon. That tends to suggest that she is capable of making her own medical treatment decisions in her own best interests, but her apparent failure to follow postoperative arrangements does undermine that suggestion.
At the hearing before us, [NXD] repeated previous accusations to the effect that the Public Trustee had deliberately withheld funds from her in retribution for making an application for review of orders made about her. Those accusations were made by way of explanation for her reliance from time to time on the Salvation Army. There is no basis for that assertion, save for [NXD's] self-serving bare assertion. The accusation is entirely consistent with other complaints to which we have referred to above, that is, almost without exception, anyone who has made a decision inconsistent with [NXD's] view of her own interests is met with accusations of dishonesty, negligence, conflict of interest or some combination of those factors.
Whether NXD required a next friend to bring these proceedings
It is apparent that the reported cases in which a court has stayed the proceedings, or set aside a judgment and ordered a retrial, or taken similar relief are ones in which it was unequivocally the case that the person concerned was under a disability either because of infancy or because of unchallenged mental incapacity. In those instances, the situation is plainly within the scope of O 70 r 2 or comparable rules and, where the point is taken by an opposing person, or the disabled person, the court must act appropriately.
However, the situation is somewhat different in instances, such as the present, where the person alleged to be under a disability directly challenges the contention that he or she is under the alleged disability and claims that she is not a person who requires the appointment of a next friend. In the present case, that very question was agitated in SAT and was determined adversely to Mrs Scates. Now, in pursuit of an uncontested right to apply for leave to appeal, she wishes to have the correctness of that decision reviewed. A determination by this court that she may not do so unless she brings the proceedings by a next friend would prevent her from doing so by relying upon the very conclusion which she desires to contend was wrongly decided and so allow that determination to prevent the judicial review which she is seeking. If, before this application for leave to appeal proceeded any further, the court was to direct that an inquiry be conducted over the question of whether or not Mrs Scates was a person under a disability, that would mean that the inquiry would be required to determine the substantial point which she seeks to have raised by this application for leave to appeal.
I certify that the preceding paragraph(s) comprise the reasons for decision of the Supreme Court of Western Australia.
