The evidence of Dr Reid ruled inadmissible
7 At the commencement of the hearing, counsel for the creditors objected to the admissibility of Dr Reid's evidence (his affidavit and the annexed report), on the ground that it does not explain how the field of specialised knowledge that Dr Reid undoubtedly possesses (psychiatry) applies to the facts assumed or observed so as to produce the opinions expressed.
8 I heard submissions on this objection on the first morning of the hearing, and ruled, before proceeding further with the hearing of the application (see Dasreef Pty Ltd v Hawchar (2011) 243 CLR 588 at 599 [19] (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ)), that Dr Reid's affidavit was inadmissible, in substance because:
(1) Dr Reid had not made explicit how his field of specialised knowledge applied to the facts which he either asserted or assumed, and, in those circumstances, it was not possible for the court to make a judgment as to whether the prerequisites of s 79 of the Evidence Act 1995 (Cth) (Evidence Act) were satisfied.
(2) Dr Reid had not stated or explained the grounds or reasoning that led to his opinions.
(3) Dr Reid had not been asked, and certainly had not purported to opine, about a critical question, namely, whether the applicant was capable of managing her own affairs in this proceeding.
9 I said that I would give more detailed reasons for that ruling in my reasons for judgment on the application, which I now do.
10 Section 76 of the Evidence Act is headed "The opinion rule". Sub-section 76(1) provides that "Evidence of an opinion is not admissible to prove the existence of a fact about the existence of which the opinion was expressed".
11 Sub-section 79(1) of the Evidence Act provides that "If a person has specialised knowledge based on the person's training, study or experience, the opinion rule does not apply to evidence of an opinion of that person that is wholly or substantially based on that knowledge".
12 As the High Court explained in Dasreef Pty Ltd v Hawchar (2011) 243 CLR 588 at 602-5 [31]-[42] (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ):
Section 76(1) expresses the opinion rule in a way which assumes that evidence of an opinion is tendered 'to prove the existence of a fact'. That manner of casting the rule does not, as might be supposed, elide whatever distinction can be drawn between 'opinion' and 'fact' or invoke the very difficult distinction which sometimes is drawn between questions of law and questions of fact. It does not confine an expert witness to expressing opinions about matters of 'fact'. Rather, the opinion rule is expressed as it is in order to direct attention to why the party tendering the evidence says it is relevant. More particularly, it directs attention to the finding which the tendering party will ask the tribunal of fact to make. In considering the operation of s 79(1) it is thus necessary to identify why the evidence is relevant: why it is 'evidence that, if it were accepted, could rationally affect (directly or indirectly) the assessment of the probability of the existence of a fact in issue in the proceeding'. That requires identification of the fact in issue that the party tendering the evidence asserts the opinion proves or assists in proving.
To be admissible under s 79(1) the evidence that is tendered must satisfy two criteria. The first is that the witness who gives the evidence 'has specialised knowledge based on the person's training, study or experience'; the second is that the opinion expressed in evidence by the witness 'is wholly or substantially based on that knowledge' …
…
It should be unnecessary, but it is nonetheless important, to emphasise that what was said by Gleeson CJ in HG [(1999) 197 CLR 414 at 427 [39]] (and later by Heydon JA in the Court of Appeal in Makita (Australia) Pty Ltd v Sprowles [(2001) 52 NSWLR 705 at 743-4 [85]]) is to be read with one basic proposition at the forefront of consideration. The admissibility of opinion evidence is to be determined by application of the requirements of the Evidence Act rather than by any attempt to parse and analyse particular statements in decided cases divorced from the context in which those statements were made. Accepting that to be so, it remains useful to record that it is ordinarily the case, as Heydon JA said in Makita, that 'the expert's evidence must explain how the field of "specialised knowledge" in which the witness is expert by reason of "training, study or experience", and on which the opinion is "wholly or substantially based", applies to the facts assumed or observed so as to produce the opinion propounded'. The way in which s 79(1) is drafted necessarily makes the description of these requirements very long. But that is not to say that the requirements cannot be met in many, perhaps most, cases very quickly and easily. That a specialist medical practitioner expressing a diagnostic opinion in his or her relevant field of specialisation is applying 'specialised knowledge' based on his or her 'training, study or experience', being an opinion 'wholly or substantially based' on that 'specialised knowledge', will require little explicit articulation or amplification once the witness has described his or her qualifications and experience, and has identified the subject matter about which the opinion is proffered.
…
A failure to demonstrate that an opinion expressed by a witness is based on the witness's specialised knowledge based on training, study or experience is a matter that goes to the admissibility of the evidence, not its weight. To observe, as the Court of Appeal did, that what Dr Basden said about the volume of respirable dust to which Mr Hawchar was exposed over time was 'an estimate' that was 'contestable and inexact' no doubt did direct attention to its worth and its weight. But more importantly, it directed attention to what exactly Dr Basden was saying in his evidence and to whether any numerical or quantitative assessment he proffered was admissible. And if, as the Court of Appeal observed, his opinion on that matter lacked reasoning, the absence of reasoning pointed (in this case, inexorably) to the lack of any sufficient connection between a numerical or quantitative assessment or estimate and relevant specialised knowledge.
(Footnotes omitted.)
13 And as Heydon JA (as his Honour then was) additionally explained in Makita (Australia) Pty Ltd v Sprowles (2001) 52 NSWLR 705 at 744 [85]:
… it must be established that the facts on which the opinion is based form a proper foundation for it; and the opinion of an expert requires demonstration or examination of the scientific or other intellectual basis of the conclusions reached: that is, the expert's evidence must explain how the field of 'specialised knowledge' in which the witness is expert by reason of 'training, study or experience', and on which the opinion is 'wholly or substantially based', applies to the facts assumed or observed so as to produce the opinion propounded. If all these matters are not made explicit, it is not possible to be sure whether the opinion is based wholly or substantially on the expert's specialised knowledge. If the court cannot be sure of that, the evidence is strictly speaking not admissible …
14 Along similar lines, the Full Court in Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd (2007) 159 FCR 397 at 420 [107]-[108] (Black CJ, Emmett and Middleton JJ) explained:
The evidence in chief of a witness giving opinion evidence must explain how the field of specialised knowledge possessed by the witness, by reason of training, study or experience, and on which the opinion is wholly or substantially based, applies to the facts established or assumed, so as to produce the opinion about which evidence is to be given. If those matters are not made explicit in chief, it would normally not be possible for the Court to make a judgment as to whether the prerequisites of s 79 have been satisfied and whether the evidence is in fact admissible.
Further, unless a witness states in his or her evidence in chief the grounds and reasoning that have led to the opinion, the opinion is valueless. Before the Court can assess the value of an opinion, it must know the facts on which it is based. If the opinion is based on irrelevant facts or facts that are clearly not going to be proved, the opinion is likely to be valueless. It should not be for a cross-examiner to endeavour to elicit the facts or assumptions upon which an opinion is expressed, and it would be unfair to leave such matters to the cross-examiner. Except in a straightforward, uncomplicated case, where the facts are admitted or otherwise readily identified, opinion evidence would normally be rejected under s 135 if the facts or assumptions upon which the opinion is based are not expressly stated.
15 It is necessary also to refer to the reasons of Edmonds J in Owners of Strata Plan No 23007 v Cross (2006) 153 FCR 398. That was a most unfortunate case in which his Honour had to determine whether Ms Cross was incapable of managing her affairs in relation to a bankruptcy proceeding at the time she was served with a creditor's petition. Ms Cross was at that time, and to the knowledge of the creditor, an involuntary patient in a psychiatric ward of a hospital.
16 Edmonds J summarised at 413 [61] the questions to be addressed in that case, having regard to the use of the words "in respect of the proceedings" in the relevantly identical predecessors to r 10.09 of the Rules and the definition of "mentally disabled person" (O 1, r4 and O 43, r 13(6) of the Federal Court Rules 1979 (Cth)), in determining capacity:
(a) whether Ms Cross had the ability to understand that she required advice in respect of the Creditor's petition which had been left with her;
(b) whether she had the ability to communicate this requirement to someone who could arrange an appointment with an appropriate advisor or, alternatively, that she could arrange such an appointment of her own accord;
(c) whether she had the ability to instruct her advisor with sufficient clarity to enable him or her to understand the situation and to advise her appropriately; and
(d) whether she had the ability to make decisions and give instructions based upon, or otherwise give effect to, such advice as she might receive.
17 In his affidavit, Dr Reid relevantly deposed:
I am able to state that there are a number of bases on which I can advance my opinions which are expressed [in the annexed report] as being Schizophrenia which dominates her mental state leading to incapacity to communicate based on fixed false beliefs and illogical form of thought.
The various bases of fact for my opinions for the previous report were the interviews that I had conducted with Ms Burnett and also the supplied transcript of an interview of her son, Mr Isherwood.
In addition to those bases, I have now been supplied with an as yet unsworn affidavit by Ms Burnett's daughter, Fiona Burnett, a copy of which is annexed ... I have considered that transcript and the circumstances that she describes about her mother's situation and this, in my view, further confirms my diagnosis as expressed in the report of 12 March 2021.
18 In his report, Dr Reid first set out matters of "background", including some details concerning a report by a Dr Mestitz dated 23 December 2012 that concluded that, despite the applicant's insistence to the contrary, she does not in fact suffer from sleep apnoea. Dr Reid then turned to answer the four questions asked of him (which, as will be seen, bear some similarity to the questions posed by Edmonds J in the Owners of Strata Plan No 23007 case), as follows:
a) Whether the person had the ability to understand that he or she required advice in respect of the relevant legal proceeding.
I had the benefit of reviewing Ms Burnett a second time and provided additional information in the form of the original sleep study by Dr Mestitz and collateral history from her son Mr Isherwood.
At interview, again I found Ms Burnett to be disorganised and illogical.
She continued to maintain the belief that she suffered a central sleep apnea and still maintained this belief when I pointed out that this was refuted by the assessment of Dr Mestitz. The study revealed that she had no apneas and he did not diagnose a central nor obstructive sleep apnea.
I conclude that this is a delusional belief. A delusion is a fixed false belief not amenable to reason. In addition past history suggests persecutory ideas. Her son reports that at times she felt that she was being observed, her telephone was tapped and her computer infiltrated.
Suspicious ideas and paranoia was played out both medically and in the legal arena. She declined a cardiac and medical stent for fear of nickel allergy and there are strong themes of persecution from legal practitioners and processors. Reports by her son suggest a deterioration of mental state over years.
Diagnostically Ms Burnett suffers the psychotic illness Schizophrenia. This is based on delusions and thought disorder in the form of illogicality. She had symptoms for many years and a deterioration her social functioning. She now had [sic] thoughts that are dominated by ideas of ill health and legal matters at the expense of social harmony and enriched family relationships.
b) Whether the person had the ability to communicate this requirement to someone who could arrange an appointment with an appropriate advisor or, alternatively, whether he or she could arrange such an appointment of his or her own accord.
Ms Burnett's Schizophrenia dominates her mental state leading to incapacity to communicate based on fixed false beliefs and illogical form of thought. She also reports short-term memory and being easily overwhelmed emotionally.
c) Whether the person had the ability to instruct the advisor with sufficient clarity to enable him or her to understand the situation and to advise the person appropriately.
As stated in my own report Ms Burnett superficially presents adequately in regard to self-care and independent living. However she is labouring under delusions and disorganised communication that would undermine her judgement on major health and property decisions.
d) Whether the person had the ability to make decisions and give instructions based upon, or otherwise give effect to, such advice as might be received.
I consider that Ms Burnett has a delusional belief about her physical health being effected [sic] from exposure to the Brickworks. This dates back to 2012. From here there appears to be a steady decline in her mental health, being preoccupied with the legal process, feeling under threat and expressing frank delusions of being observed and persecuted by others to her son. Anxiety dates back to 2003. Psychotic symptoms are unlikely to have been present continuously through the period starting at the Magistrates Court to her current predicament. I do not believe that Ms Burnett has the capacity to manage her own affairs. I feel that her delusional beliefs have dominated her thinking and pursuit of outcomes through the legal system. Given her illogical communication, I would argue that she lacks capacity. I found that she is formally thought disordered which significantly impacts on her ability to communicate with others. Her illogicality would impact on her ability to instruct or advise others. Many of her ideas are fixed and therefore she struggles to take advice.
19 I should interpolate at his point that there was a dispute about whether the word "unlikely" in the final paragraph of the above extract is a typographical error, or not. It was unnecessary to consider the point, in the view I took of the inadmissibility of the report as a whole.
20 A number of things may be said about what Dr Reid said in answer to those questions that go to the admissibility of his evidence.
21 As to answer a), his conclusion that the applicant's belief that she suffers a central sleep apnoea is delusional, because Dr Mestitz said 8 years earlier that she did not, strikes me as susceptible to the criticism that it is both irrelevant to the inquiry and forensically dubious given the age of Dr Mestitz's report. In any event, and more importantly, Dr Reid's conclusion that the applicant "suffers the psychotic illness Schizophrenia … based on delusions and thought disorder in the form of illogicality", has "had symptoms for many years and a deterioration in her social functioning", and "now ha[s] thoughts that are dominated by ideas of ill health and legal matters at the expense of social harmony and enriched family relationships" is just that - a conclusion. Absent "the grounds and reasoning that have led to the opinion, the opinion is valueless". Cf Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd (2007) 159 FCR 397 at 420 [107] (Black CJ, Emmett and Middleton JJ).
22 As to answer b), Dr Reid does not, with respect, at all address the question asked of him.
23 As to answer c), the same may be said. It is also unclear what "report" he has in mind.
24 As to answer d), whatever other shortcomings it has, Dr Reid was not asked, and thus unsurprisingly did not say, whether the applicant is currently capable of managing her own affairs in this proceeding. In my view, the answer is, and was bound to be, valueless to the task at hand.
25 For those reasons, in my view, Dr Reid did not explain how his field of specialised knowledge applied to the facts established or assumed so as to produce his opinions, and did not state in his evidence the grounds and reasoning that led to those opinions. His evidence is thus inadmissible.
