Question of law 1
92 There are two primary aspects of this question. The first is whether the AAT addressed the way the applicant put her case and, in particular, her reliance on paragraph (a) of the definition of "medical treatment". If that matter is determined in the applicant's favour, the second matter is whether the AAT's error is material.
93 In my respectful view, there is little or no doubt that, inexplicably, the AAT failed to address the case as put by the applicant. Comcare did not dispute, either below or in the appeal, that the applicant's case relied upon paragraph (a). Comcare put its own case in exclusive reliance on paragraph (b). As the AAT's reasons for decision reveal, the AAT considered and determined only Comcare's case. Notably, the AAT made no express reference at all to paragraph (a) in its reasons for decision despite the fact that this provision was at the heart of the applicant's case.
94 Nor was the applicant's case as put implicitly addressed by the AAT. I reject Comcare's submission that [3] of the AAT's reasons for decision demonstrates that it "clearly understood" that the applicant's case was put under paragraph (a). No inference can be drawn from the wording of [3] as to which particular paragraph of the definition of "medical treatment" the member had in mind when she purported to summarise the applicant's case.
95 The critical and perhaps more contestable issue, however, is whether the AAT's patent error was material. For the following reasons, I consider that it was.
96 The AAT's error was not simply a failure to address and determine a substantive submission advanced on behalf of the applicant. The error was more fundamental. It involved a total failure to address and determine the applicant's case as put.
97 Although the parties differed in their primary reliance on paragraphs (a) and (b) respectively of the definition of "medical treatment" in s 4, it is evident from each of their statements of issues, facts and contentions as filed in the AAT that there was broad agreement between them as to the nature of other issues which fell to be determined.
98 The applicant's statement of issues, facts and contentions identified the following issues as relevant:
1. Whether the applicant is entitled to compensation for costs associated with breast reduction surgery by Dr Milovic, Plastic Surgeon on 2 November 2009. This requires consideration of:-
(a) whether the surgery was 'in relation to' the Applicant's injury; and
(b) whether the surgery was treatment reasonable for the Applicant to obtain in the circumstances.
99 In its statement of issues, facts and contentions, Comcare identified the relevant issues in precisely the same terms.
100 Thus the significant difference between the parties was the premise upon which those issues fell to be determined. For the applicant, that premise was paragraph (a). For Comcare, that premise was paragraph (b). The critical question is whether those different premises could have any impact upon the otherwise agreed remaining issues which the AAT had to determine.
101 For the following reasons, that question should be answered in the applicant's favour.
102 First, I do not accept Comcare's submission that the test is whether the AAT's error would have affected the outcome. The correct test is to ask whether the AAT's error could have affected the outcome.
103 In Australian Broadcasting Tribunal v Bond [1990] HCA 33; (1990) 170 CLR 321, Toohey and Gaudron JJ made the following observations at 384 which, although directed to the need for an error of law to be material for the purposes of the Administrative Decisions (Judicial Review) Act 1977 (Cth), are equally applicable to a s 44 AAT Act appeal:
For an error of law to constitute a ground of review under s. 5(1) of the A.D.(J.R.) Act it is necessary that "the decision [involve] an error of law": s. 5(1)(f). For an error of law to be involved in a decision something more than the mere occurrence of error is necessary. The error must have contributed to the decision in some way or, at the very least, it must be impossible to say that it did not so contribute. Conversely, an error is not involved in a decision if it did not contribute to the decision or if the decision must have been the same regardless of the error. Thus, to show that an error of law is involved in a decision it is necessary, at the very least, to show that the decision may have been different if the error had not occurred. This approach may be compared with the operation of the rules of natural justice where an allegation is made to which a person has no opportunity to respond. …
(Emphasis added).
104 A similar test was approved by the Full Court in Bridges v Minister for Immigration and Multicultural Affairs [2001] FCA 1647; (2001) 114 FCR 456, in the context of an appeal from a judgment of a judge of this Court who dismissed an appeal on a question of law under s 44(1) of the AAT Act. At [10], Sackville, Kiefel and Hely JJ identified the correct test as follows:
The governing principle is that a decision of an administrative tribunal will be set aside for error of law if it can be shown that the error could have affected the outcome of the case, that is that a different result might have been reached had no error of law been made.
Justices Nicholas and Robertson described the test in similar terms in Gilkinson v Repatriation Commission [2011] FCAFC 133; (2011) 197 FCR 102 (Gilkinson) at [30].
105 Secondly, it is telling that, in considering whether the breast reduction surgery was "in relation to" the compensable injuries and also whether that surgery was treatment that was "reasonable" for the applicant to obtain in the circumstances for the purposes of s 16 of the SRC Act, the AAT proceeded on the basis that the surgery was a "therapeutic treatment" within the meaning of paragraph (b). The AAT's consideration of those matters was coloured by its belief that the surgery constituted a "therapeutic treatment". There is some uncertainty as to whether that consideration would have been the same if these matters had been considered by the AAT through the prism of paragraph (a).
106 There are at least two relevant differences between paragraphs (a) and (b):
(a) no issue of "therapeutic treatment" is raised by the wording of paragraph (a); and
(b) as Hill J observed in Thiele at [20], another difference "is that the medical or surgical treatment must be 'by, or under the supervision' of the doctor to fall within paragraph (a) whereas the therapeutic treatment referred to in paragraph (b) need only be shown to have been obtained 'at the direction' of the doctor".
107 The AAT's exclusive focus on paragraph (b) meant that it addressed issues which it considered were presented by that particular definition of "medical treatment", which then influenced its findings as to whether Comcare was liable for that surgery under s 16 of the SRC Act. For example, at [41] of its reasons for decision, the AAT accepted that Dr Milovic and Dr Taylor had "directed" the applicant to undergo breast reduction surgery. While such a finding was relevant to the way that Comcare put its case, it was irrelevant to the applicant's case under paragraph (a). There could be no dispute that, for the purposes of that provision, the applicant had undergone surgical treatment in the form of breast reduction surgery by, or under the supervision of, a legally qualified medical practitioner, namely Dr Milovic. Both Dr Milovic and Dr Taylor had advised the applicant to proceed with that treatment on the basis that it was likely to help relieve her pain.
108 The AAT's exclusive focus on paragraph (b) led it to dwell on matters arising from its assumption that the breast reduction surgery was a "therapeutic treatment" for the applicant's compensable injuries.
109 For example, the AAT's finding in [44] of its reasons for decision that neither Dr Milovic nor Dr Taylor considered breast reduction surgery was specifically treating the applicant's compensable injuries, or symptoms that resulted from those injuries, was driven by the AAT's assumption that this surgery was a "therapeutic treatment". The same assumption seems to have informed the AAT's finding in the same paragraph that the evidence suggested that neither of those doctors "even knew what the pathological nature of Ms Howes' compensable injuries were at the time they directed her to undergo the procedure". The AAT found that these doctors had advised breast reduction surgery because it "may help neck and back pain caused by heavy breasts, not caused by C5-C6 disc prolapse or by impingement and subacromial bursitis". The AAT found that the surgery was recommended by both these doctors "as a way of relieving pain in the neck and shoulders due to excessive weight of her breasts".
110 It is not easy to reconcile those findings with all the evidence. In particular, there was evidence before the AAT which indicated that both these doctors considered that breast reduction surgery would assist the applicant in dealing with her C5-C6 disc injury. For example, in the case of Dr Milovic, his file relating to the applicant (which was produced on summons and was in evidence before the AAT), included a document entitled "Procedural Consent Form" in which the applicant herself had written that Dr Milovic had explained to her that she had the following condition:
Breasts large & heavey (sic) requiring reduction. C5/C6 disc injury - reduction will assist.
111 Perhaps even more significantly, in his letter dated 22 July 2009, which was written to the applicant's general practitioner, Dr Milovic wrote:
I believe that Roseanne would benefit from bilateral breast reduction and I believe that she will have a relief of the pain in her shoulders and back after this procedure.
(Emphasis added).
112 And in the case of Dr Taylor, in his report dated 15 September 2009, which was also written to the applicant's general practitioner, express reference was made to the applicant's suffering from "neck and upper back pain, shoulder grooving" and that she also felt that her breast size exacerbated her existing right shoulder problem. Dr Taylor acknowledged that the applicant needed to lose weight but he said that breast reduction could be done now "and would help her exercise and lose weight". He also advised that he expected that the applicant would "find an improvement in her neck and back pain from the reduction weight (sic)", in the context of her undergoing breast reduction surgery.
113 It is unnecessary in this appeal to reach a concluded view as to whether or not the AAT erred in disregarding this evidence in reaching the findings that it made in respect of paragraph (b). The relevant issue is that it is at least possible that the AAT may have reached different findings, having regard to this evidence, if it had focused its attention on the way that the applicant put her case, namely that she had undergone surgical treatment by Dr Milovic, which was supported by Dr Taylor, and she maintained that this treatment was in relation to her compensable injuries and was reasonable.
114 Thirdly, at [45] of its reasons for decision, the AAT acknowledged that it was arguable that Drs Milovic and Taylor directed the applicant to undergo breast reduction surgery to treat excess weight, "which was an issue that needed addressing as a prerequisite to the treatment of the compensable conditions". But the AAT then added at [46] that, even if that was so, the applicant's claim would fail as she found that the primary reason for the applicant undertaking the breast reduction "was more likely to be cosmetic" and also because "such a procedure was not reasonable treatment for excessive weight, even if the weight loss was required urgently".
115 As noted above, the AAT embarked upon a detailed analysis with a view to determining the purpose for which the breast reduction surgery was undertaken. It concluded that the applicant underwent breast surgery "primarily for cosmetic reasons". It acknowledged that the applicant may have thought that the surgery might assist her neck pain by reducing some of the weight in her breasts, but it added that "surgery is not therapeutic merely because it may provide some benefit to the applicant's compensable injuries". It concluded at [47] that the applicant would have undergone breast reduction surgery in early November 2009 regardless of whether it may or may not have helped relieve her pain.
116 The emphasis of the AAT's analysis on the issue of purpose was very much on the applicant's motivation in having the surgery, rather than upon the advice she received that she should undergo that surgery as it was likely to benefit her back and shoulder pain.
117 The AAT's concentration on the applicant's motivation for having the surgery (as opposed to the advice given by Dr Milovic and Dr Taylor), is reflected in the weight it attached to the fact that the applicant failed to mention the breast surgery to numerous medical practitioners who treated her in the period from September 2010 to 27 December 2012, i.e. after the operation had taken place. In [66] of its reasons for decision, the AAT described as "unusual" that the applicant had not mentioned the operation when she was providing the history of her treatment of her injuries. It concluded that the likely reason why the surgery and its benefits were not referred to in any of the medical reports during that post-operation period "was because Ms Howes did not regard the surgery as a treatment for her compensable injuries". This fortified the AAT's conclusion that the applicant had not undergone the procedure for the primary purpose of treating her compensable injuries.
118 It is unclear whether these matters would have figured so prominently if the AAT had focused on paragraph (a) and not merely paragraph (b).
119 Fourthly, as is evident from the terms of the AAT's reasons for decision (see, for example, [69]), in determining whether the breast reduction surgery was "reasonable" the AAT posed the relevant question as "whether weight reduction treatment was reasonable therapy for Ms Howes' compensable injuries, and if so, weather (sic) breast reduction surgery was a reasonable form of therapy to treat excessive weight".
120 The AAT's approach to this issue was directed to its earlier finding that the surgery was a "therapy" to reduce the applicant's excessive weight. The AAT found at [70] that Ms Howes' weight gain after December 2008 was as a result of medications which she took to relieve the pain from her compensable injuries. In the event, however, the AAT stated at [78] that it made no finding as to whether reduction was a reasonable treatment for the compensable injuries because, even if it were, the claim would fail because the breast reduction surgery was not the most cost effective means of treating the applicant's excessive weight. In concluding that the surgery was not "reasonable" for the purposes of s 16, the AAT also took into account its finding that the surgery was not part of the applicant's treatment plan. In reaching that conclusion, the AAT applied Chowdhary. The member viewed that decision as important because of the emphasis which it placed on "the importance of an appraisal and/or indication that the treatment is part of a plan, for permanent improvement in the health of an employee" (see [85]). It added at [86] that this was particularly important "when costly expenditure is contemplated".
121 Chowdhary related to a claim to be compensated in respect of physiotherapy treatment in respect of back pain which the claimant said was associated with her employment as a clerical assistant in the National Library. One of the issues in Chowdhary was whether the applicant there had refused or failed, without reasonable excuse, to undertake a rehabilitation program as required by s 37(3) of the SRC Act. The AAT found that the applicant did not have a reasonable excuse for refusing to undertake the rehabilitation plan proposed for her.
122 There were conflicting medical opinions before the AAT as to whether there was a need for the applicant to have physiotherapy as part of her medical treatment. On the question whether it was reasonable for the applicant to obtain physiotherapy treatment, the AAT said in obiter that, if it had jurisdiction to review the relevant decision, it would have found against the applicant on this issue. The applicant commenced physiotherapy after her initial back injury in 1987 and continued to receive it into 1996. The AAT's reasons are set out in [53] of Chowdhary (which appears to be the paragraph relied upon by the AAT in this case):
… Dr Champion speaks of there being a need for "carefully appraised courses" of physiotherapy, but there is no evidence before us to suggest that there has been such an appraisal. In particular, there is no evidence of any plan to have the physiotherapy treatment accompanied by a course of physical exercise such that the applicant might become re-conditioned and better able to cope with pain and manage a return to work. While provision of temporary relief from pain through physiotherapy will in many circumstances qualify as medical treatment which it is reasonable for an employee to obtain, there will in some cases come a point where it is no longer reasonable unless it is part of a plan for permanent improvement in the health of the employee; (cf Re Payne and Comcare (Decision No 11624, 19 February 1997, at para 21ff).
123 It is evident that the relevant remarks in Chowdhary were directed to paragraph (b) of the definition of "medical treatment" and not paragraph (a). (Although it might be noted that in that case the AAT made express reference to neither of those paragraphs).
124 The AAT's emphasis upon whether the breast reduction surgery was part of a plan appears to have resulted from its exclusive focus on paragraph (b). The AAT was critical of the fact that the applicant had not sought and obtained Comcare's approval to the breast reduction surgery before it occurred. It found that this meant that Comcare was not given an opportunity to determine whether or not "the therapy is an appropriate part of the treatment plan for Ms Howes" (see [86]). The AAT then proceeded to find that, by deciding to have the breast reduction surgery when she did, the applicant "interfered with" Dr Damiani's treatment, who recommended physiotherapy and hydrotherapy around the time the surgery took place.
125 For the purposes of this appeal, it is unnecessary to determine whether the AAT's analysis of Comcare's case was erroneous in law. What is important is that that analysis was driven by the AAT's exclusive focus on paragraph (b) and in total disregard of paragraph (a). In particular, because of its exclusive focus on paragraph (b), the AAT failed to turn its mind to whether, in determining liability under s 16(1) in respect of medical treatment under paragraph (a) of the definition, it is relevant to make findings and take into account such matters as:
(a) the applicant's motivation in deciding to have the breast reduction surgery; and
(b) whether the surgical treatment had to form part of some wider treatment plan for it to be considered to be "reasonable" for the purposes of s 16.
126 Whatever relevance these matters might have for the purposes of a claim made under paragraph (b) (which it is unnecessary to decide in this appeal), it is difficult to see their relevance to a claim which relies on paragraph (a). That is particularly so in the case here, where both Drs Milovic and Taylor advised the applicant that breast reduction surgery should benefit her pain relief.
127 All these matters demonstrate that the AAT's failure to turn its mind to the way the applicant put her case could have affected the outcome. Consequently, applying the correct test as to whether or not an error is material, I find that the AAT's error was material.
