decision of perram j
21 As the parties' submissions relied heavily upon the decision of Perram J, it is first necessary to set out a summary of his Honour's reasons. Similar to this matter, Edser appealed against the Decision of the Authority which affirmed QSuper Board's determination not to pay the applicant TPD benefit. The appeal raised six questions of law, and ultimately turned on four matters:
(1) Whether the Authority failed to consider a mandatory relevant consideration;
(2) The definition of "pre-existing medical condition";
(3) The proper construction of the words "not related to" in cl 6.2(b) of the Insurance Terms; and
(4) The application of the Insurance Contracts Act 1984 (Cth).
22 The applicant's first question of law was whether the Authority properly considered whether the decision was "fair and reasonable" in accordance with s 1055 of the Corporations Act. The applicant contended that the Authority did not determine the duration of his insured membership with QSuper and therefore failed to consider his eligibility for the TPD benefit under cl 6.2(c) of the Insurance Terms (at [15]). His Honour rejected this ground, finding that if the Authority had considered the applicant's eligibility under cl 6.2(c) it would have been bound to conclude that he was not eligible as he would have had to be an "insured member" for between 2 and 7 years (at [16]). His Honour found that the applicant became an insured member on 31 October 2011, and ceased when he became TPD on 3 January 2013, in accordance with cl 11.1(b) of the Insurance Terms (at [23]). Accordingly, the applicant was never eligible to make a claim pursuant to cl 6.2(c) (at [23]). His Honour concluded that the applicant could only make a claim pursuant to cl 6.2(b) stating that, consistent with Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323; [2001] HCA 30 at [10] (Gleeson CJ) and [68]-[69] (McHugh, Gummow and Hayne JJ), it is well established that provisions of this sort do not impose an enforceable obligation on a decision maker to make a particular finding of fact (at [25]).
23 The second question of law asked whether the Authority's construction of "pre-existing medical condition" was too expansive. The applicant submitted that the Authority treated a prior diagnosis in 1998 as evidence of a continuous depressive condition which existed up until the applicant became an insured member, despite evidence from doctors showing that depressive conditions might resolve (at [28]-[29]). His Honour considered each parties' view on this question, detailing at [30]:
The first, which was advanced by QSuper, was that [the applicant's] depressive episodes (including those which he experienced after mid-2012) were instances of a single underlying depressive condition which had manifested itself. The second, advanced by [the applicant], was that these episodes were distinct medical conditions, each of which had fully resolved and as such did not reflect the existence of a single underlying depressive condition. There was evidence before the panel capable of supporting both views.
24 At [31], his Honour found that:
The [Authority] thought that the preferable view was that there was a single underlying depressive condition. That being its factual conclusion, I am unable to see how it can be said that it misapplied the definition in concluding that that condition was a 'medical condition the signs or symptoms of which existed before the start of the member's insured membership'. On the facts it had found it plainly was.
25 Accordingly, at [33], his Honour determined that "no occasion arises to interfere with the decision made by the [Authority] on this basis".
26 In relation to the third question of law, his Honour made the following observations at [35]:
However, it was not enough for the [Authority] merely to identify that [the applicant] had some pre-existing medical condition. The language of cl 6.2(b)(ii) cast upon it the burden of a [sic] answering a further question. For [the applicant] to be eligible for the TPD benefit the [Authority] had to be satisfied that the TPD was 'not related to' the pre-existing medical condition. This required the [Authority] to reach a view on the meaning of 'related to'. It did so, and concluded that 'if the [applicant's] identified pre-existing medical condition was causally or clearly connected to the [applicant's] TPD, clause 6.2 operated to exclude payment of his TPD benefit'.
27 The applicant, relying on a medical report of Professor Alexander McFarlane, submitted that it was "impossible… to determine whether his pre-existing condition was a clear cause of his TPD without having some understanding of the extent of the role that the bullying and threats had played in the TPD" (at [38]). The report observed and concluded:
The question then arises as to what the relationship is between [the applicant's] prior episodes of depression and the episode of depression he developed subsequent to this employment in November 2011. It is important to not dismiss the significance of the stressors that [the applicant] was exposed to in his employment or their capacity, independent of his prior history or vulnerability, to cause a psychiatric disorder. In this context, the word vulnerability indicates that an individual has a greater probability of developing an episode of depression due to the fact of his experiencing previous episodes of depression. In my opinion, there was a significant risk to his mental health as a consequence of the exposures that are the subject of the compensation claim arising from this period of employment beginning in 2011. In this setting risk refers to the probability that an asymptomatic individual will develop an episode of a psychiatric disorder. However, that is not the question that I have been asked to express an opinion about. The question is as to the nature of the relationship between his prior episodes or psychiatric symptomatology and his subsequent symptoms.
…
…having considered the body of information provided, the episodes of depression that the complainant had experienced prior to 2011 are related to the condition that he developed and experienced in 2014. Those prior episodes influenced both the severity of his symptoms and the probability of their reoccurrence.
28 At [59], His Honour considered that the Authority applied a two-limbed test to determine its satisfaction of the words "related to", which included consideration of whether there was a causal connection between the applicants' pre-existing medical condition and his TPD, or whether there was a clear connection between the two. In that regard, his Honour found at [60] that the Authority:
…appears to have proceeded on the basis that if the TPD would not have occurred but for the existence of his pre-existing medical condition, then it could be said that the two were related within the meaning of cl 6.2(b)(ii).
29 His Honour determined that this resulted in a misapplication of cl 6.2(b)(ii) of the Insurance Terms (at [61]). His Honour regarded the words "related to" as "elastic and, depending on context, connote a wide range of relationships of connection" (at [62]). His Honour made the following findings at [67]-[68] and [71]:
It seems to me that the most plausible interpretation of cl 6.2(b)(ii) is the one proposed by QSuper: that the connection required is one of clear causation. This standard will not be satisfied by the mere satisfaction of the but-for test. The decision maker will need to be satisfied that the pre-existing medical condition is causally connected to the TPD in a way which is clear.
Consequently, I accept that the [Authority] did not correctly apply the correct causal standard. Instead, it asked itself two questions, neither of which was the correct one. It was not correct to ask whether the TPD was merely causally linked to the pre-existing medical condition because this was apt to encourage the application only of a but-for standard of causation. This risk appears, in fact, to have come to pass. Nor was it correct to ask - as the [Authority] did - whether there was a clear connection without a causal element.
…
Once a test of clear causation is applied I do not see the language of cl 6.2 as altogether ousting any contention that the effect of the bullying and threats was itself so substantial that it denied any clearly causative role to his pre-existing medical condition. It will depend on the facts. Certainly, if this argument is advanced to the [Authority] on remitter it is a matter that it will need to address.
30 At [72], his Honour identified difficulties, perhaps "surmountable", with Professor McFarlane's report insofar as it contained two ambiguities which would need to be resolved for any proper consideration of the issues which arise. The reference to "asymptomatic individuals" could, his Honour stated, be to "persons devoid of any form of psychological disorder" or alternatively to "persons with an underlying condition not presently displaying symptoms". The second ambiguity involved the reference to "that the stressors might produce psychiatric symptoms in such an individual". There, the ambiguity involved whether the stressors experienced by the applicant would induce "psychiatric symptoms in otherwise healthy individuals but it may not have made them TPD". His Honour made no determination on these issues.
31 With respect to the final question of law, relating to the application of the Insurance Contracts Act, the Authority made a finding that the Act did not apply to the complaint (at [74]). The applicant contended that he was denied procedural fairness and that the Authority erred in making this determination (at [75]). His Honour found that the applicant was not denied procedural fairness as the applicant made no submission that the Authority should have applied that Act, and it is therefore immaterial whether the Authority's finding on that point was correct or not (at [76]-[77]).
32 Based on his Honour's finding in relation to question three, the decision was remitted to the Authority for re-determination in accordance with his Honour's reasons (at [81]).
33 While the parties expressed it in slightly differently terms, it was effectively common ground that a number of clear principles emerged from the judgment of Perram J. I adopt the propositions as helpfully distilled by Mr Kelsey-Sugg for the applicant, as follows:
1. For the TPD to be 'related to' the pre-existing medical condition within the meaning of cl. 6.2(b)(ii), the pre-existing medical condition is not required to be the proximate, dominant or effective cause of the TPD: [63] and [66].
2. Although not required to be the proximate, dominant or effective cause of the TPD, the pre-existing medical condition must at least be a non-trivial and sufficient cause of the TPD: [66].
3. Clause 6.2(b)(ii) can operate where there are multiple non-trivial and sufficient causes of the TPD, including amongst them a pre-existing medical condition: [66].
4. The connection required between the pre-existing medical condition and the TPD in order to disentitle a person from payment of a TPD benefit under cl. 6.2(b)(ii) is one of "clear causation": [67].
5. The standard of clear causation is not satisfied by the mere satisfaction of "the but-for test": [67].
6. While the standard of clear causation is not satisfied by mere satisfaction of the but-for test, a but-for element remains a necessary condition of the clear causation test: [53]; [68].
7. The decision-maker will need to be satisfied that the pre-existing medical condition is causally connected to the TPD in a way which is clear.
34 An additional proposition, identified by Mr Holyoak for QSuper Board, which I accept and also adopt is:
The alleged bullying and threats must be so substantial that they deny any clearly causative role for any pre-existing medical condition, which is a factual question.
