3.3 The Tribunal erred in its understanding of the concept of "injury" under the Act
46 It is well established that the applicant bears the onus of demonstrating an error of law on the part of the Tribunal. It is also well established that the reasons of an administrative decision-maker "are not to be construed minutely and finely with an eye keenly attuned to the perception of error": Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259 at 271-272 (Brennan CJ, Toohey, McHugh and Gummow JJ (quoting with approval Collector of Customs v Pozzolanic (1993) 43 FCR 280 at 287)). As such, when it is said that such reasons should be read beneficially, ultimately this means that "a commonsense and realistic approach should be taken to understanding the reasons as a whole to see what it was that the Tribunal was saying": Fang Wang v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCA 1044 at [14]-[15] (Allsop J (as his Honour then was)).
47 Applying this approach, a fair reading of the Tribunal's reasons demonstrates that the applicant's construction is to be preferred for the reasons given below. As a result, it is apparent that the Tribunal must have erred in its understanding of the concept of an "injury" under the Act because its finding at [37] should have led it to conclude that the requisite causal connection was established between the applicant's chronic pain syndrome and the accepted primary injury.
48 First, the applicant plainly put in issue before the Tribunal the question of whether her chronic pain syndrome was caused by the accepted primary injuries sustained by her directly as a result of the 2006 accident. Thus the applicant defined the first issue before the Tribunal as whether she continues to suffer from her incapacity and this incapacity "results from" the compensable injury so as to fall within the ambit of s 14(2) of the Act (applicant's statement of issues, facts and contentions filed in the Tribunal dated 20 September 2016 (the applicant's SIFC) at [13]) (Supplementary Appeal Book Pt C (Supp AB) at p. 46). Thus, under the heading "Contentions" in the applicant's SIFC, she alleged that:
(1) the opinions of Drs Coyle, Obermeder, Le Leu and Paul should be preferred over that of Dr Vecchio (applicant's SIFC at [16]);
(2) "… the soft-tissue injuries have evolved into a regional pain syndrome" (applicant's SIFC at [17]; emphasis added);
(3) on the balance of probabilities, the applicant's present injuries are a continuation of the compensable injuries sustained in 2006 (applicant's SIFC at [18]); and
(4) accordingly, Comcare remains liable under s 14(2) of the Act for her present injuries (applicant's SIFC at [20]).
(See also the transcript of submissions before the Tribunal, Supp AB at p. 57.33-57.44)
49 Secondly, Dr Paul, whose evidence was among that preferred by the Tribunal, clearly used the word "secondary" in a causative sense in his report of 24 June 2016 in the passage quoted by the Tribunal at [32] of its reasons. That passage appears at page 8 of the report under the heading "Diagnosis" in which Dr Paul expressed the opinion that:
Soft tissue injuries following motor vehicle accident in March 2006 affecting her neck, right shoulder, upper limbs on both sides and right hip. The right hip soft tissue injury has resolved, however, she appears to have gone on to develop a chronic pain syndrome secondary to the soft tissue injuries [she suffered in the 2006 accident].
50 Similarly, in answer to the question "[i]n your opinion, and based on the medical evidence before you, is Ms Howard currently suffering from the effects of her accepted conditions? If not, when did they resolve", Dr Paul responded:
Ms Howard is not suffering from the accepted condition which includes her neck sprain and contusion of upper arm and finger, hip and thigh on the right.
She, however, has developed a chronic pain syndrome secondary to the subject accident injuries. The sprains and contusions would likely have resolved within three months of the subject accident.
51 Furthermore, in answer to the question of whether, if the applicant does not suffer from the effects of her accepted conditions, she suffers from a different condition and if so, as to the cause of that condition, Dr Paul said that:
She has gone on to develop a chronic pain syndrome. This is based on her history of constant pain since the accident and the affected areas except for the right hip and thigh.
(emphasis added)
52 In addition, in answer to the question of whether the applicant required medical treatment for her accepted conditions on and from 23 March 2015 and in the future, Dr Paul considered that the applicant would benefit from referral to an evidence-based multidisciplinary pain management program.
53 For all of these reasons it is therefore plain, and must have been plain to the Tribunal, that Dr Paul was using the term "secondary" in a causative sense, i.e., to say that the chronic pain syndrome developed out of the soft-tissue injuries after the date of the 2006 accident and had continued despite the soft-tissue injuries having been completely resolved.
54 Thirdly, when the Tribunal found at [37] that the applicant "developed a chronic pain secondary to the injuries she suffered in the 2006 accident", it can reasonably be inferred that the Tribunal was using the term "secondary" in the same sense as that used by Dr Paul given in particular that:
(1) the Tribunal accepted Dr Paul's evidence at [36]; and
(2) the finding is one of the findings expressly made at [37] on the balance of probabilities "[h]aving regard to the medical evidence".
55 Furthermore, if the Tribunal had accepted only some, but not all, of Dr Paul's evidence, it can be inferred that it would have qualified its acceptance of Dr Paul's evidence accordingly and explained the different sense in which it used the word "secondary" at [37] of its reasons. This is particularly so given that the question of whether the chronic pain syndrome arose out of the 2006 injury in a causal sense was central to the applicant's case and that the applicant relied upon Dr Paul in support of her case on this issue: see above at [48]; see also the requirement to include findings on material questions of fact in s 43(2B) of the AAT Act.
56 That being so, the Tribunal's acceptance of Dr Paul's evidence cannot be reconciled with its finding at [39] that the applicant does not continue to suffer the effects of her 2006 injuries. That in itself is sufficient to establish that the Tribunal must have erred in its understanding of the concept of an "injury" under the Act, as the respondent conceded.
57 I am reinforced in my view that the Tribunal's reasons are properly construed in the manner for which the applicant contends by the Tribunal's focus upon the question of whether there was a continuing organic pathology which provided a connection between the chronic pain syndrome and the 2006 accident. This apparently explains why the Tribunal did not consider that the finding at [37] established the necessary causal link for the purposes of the Act.
58 First, while the Tribunal preferred both Dr Paul and Dr Vecchio's evidence, it must be borne in mind that the evidence of Dr Vecchio, who is a rheumatologist, was ultimately that there was no organic issue arising from the primary injury which explained why the applicant continued to suffer pain. It was in that context that he found that her continuing symptoms are unlikely to relate to the accident and considered it more probable that there was an alternative cause relating to the human psyche "that could be perpetuating the pain or causing the pain".
59 Secondly, the Tribunal at [36] rejected Dr Gorman's evidence that the applicant's current condition is connected with "the events of 2006" because it was premised upon the effect of the 2006 injuries having continued substantially unchanged since the 2006 accident. Yet, in the Tribunal's view, Dr Gorman's evidence that there was an increase in the applicant's range of movement despite the cessation of treatment 18 months earlier meant that there had been some change in her condition, thereby undermining Dr Gorman's premise. This clearly indicates that the Tribunal assumed that there must be a continuing connection between the organic injuries suffered in 2006 and the chronic pain syndrome. It was not sufficient, in other words, if the symptoms of chronic pain alone continued.
60 Thirdly, pivotal to the Tribunal's conclusion at [39] that the applicant does not continue to suffer the effects of her 2006 injuries was the finding at [38] that "[n]one of the medical experts suggested a mechanism by which the 2006 injuries could continue to cause Ms Howard's current condition" given that the soft tissue injuries resolved within 3 to 6 months and that none of the scans had revealed a pathology attributable to the 2006 accident which could explain her condition. Nor, the Tribunal found, was there any evidence on the basis of which the Tribunal could find that the applicant suffered from a psychological condition.
61 As I have indicated, these matters suggest that the Tribunal failed to appreciate that medical conditions like chronic pain syndrome, which evolve out of primary injuries, are just as much an injury for the purposes of the Act as the primary injury. This explains the Tribunal's focus upon whether organic or psychological injuries directly arising out of the 2006 accident provided an explanation for the applicant's chronic pain syndrome, which it accepted at [18] had been experienced by her ever since the 2006 accident at varying levels primarily in her upper neck and shoulder blades. However, the correct position under the Act is that it sufficed if the chronic pain syndrome was caused by the first injury, as the Tribunal accepted in finding as a matter of fact that the chronic pain syndrome was secondary to the injuries suffered in the 2006 accident in line with Dr Paul's evidence. This error is, with respect, analogous to that made by the Tribunal in Canute which treated the concept of "injury" as co-extensive with the workplace incident save that here the Tribunal appears to have treated the concept of "injury" under the Act as co-extensive with the primary injury.
