Ground of appeal 1
39 The first ground of appeal was that:
1. The Tribunal erred in law by concluding Mr McQueen-Thomson suffered incapacity for work as a result of a left shoulder condition(s), without considering whether his incapacity for work was the result of 'an injury', within the meaning of ss5A (1), 5B (1) and 14 (1) of the SRC Act, as distinct from his non-employment related pre-existing left shoulder ailment that did not constitute such 'an injury'.
40 In summary the employer submitted:
There was no basis for the Tribunal's conclusion at [68] that the employee had suffered an injury to his left shoulder which had resulted in his incapacity for work or impairment
The Tribunal erred at [69] in stating that the existence of an injury and subsequent incapacity was not in issue
Section 14 of the SRC Act refers to an injury resulting in death, incapacity for work or impairment. Only incapacity is relevant in this case.
The only comments in the Tribunal's decision concerning incapacity were at [30], [68], [69] and [97]. The Tribunal's finding at [97] that the employee cannot drive trucks is the only finding in respect of incapacity.
While the employer accepts that the employee has an injury, and further that he suffers an incapacity for work, the Tribunal did not squarely engage with the question the Tribunal needed to ask itself under s 14 of the SRC Act read in light of s 4(9) of the SRC Act, namely whether the injury caused the incapacity. It was critical that the Tribunal find that link in light of the evidence of a strong underlying pre-existing problem with the left shoulder, and evidence that the employee continued to work full-time for two months after the workplace injury of May 2014.
41 The employee submitted that:
In the Tribunal the key issue was whether the employee's condition was an injury simpliciter, a disease or the aggravation of a disease.
In the Tribunal the employer argued that the condition of the employee should be regarded as a disease, and therefore he was precluded from claiming compensation by the operation of s 7(7). The employer did not argue any particular fact or circumstance relating to incapacity for work
The connection between the injury to the employee and the employee's incapacity was not contested by the employer in the Tribunal. It was for this reason that the Tribunal observed that the issue was not in contention.
At the end of the discussion concerning disease and in circumstances where the Tribunal rejected the submission that there was an injury other than a disease, the Tribunal made explicit findings at [97] that the employee's injury was not merely an aggravation of a prior symptomatic ailment, but the result of an employment contribution to the development and the worsening of an ailment. These findings were referable to the precise language of the SRC Act.
42 The employee relies on authorities including Ilsley v Wattly Australia Pty Ltd [1997] FCA 427.
43 In my view the Tribunal did properly engage with the issue required for determination under s 14 SRC Act, namely whether the employee's incapacity "resulted from" the relevant injury. I have formed this view for the following reasons.
44 First, and contrary to the claims of the employer, I am not satisfied that there was error in the statement of the Tribunal at [69] that "the question of the existence of an injury and subsequent incapacity was not in issue". Certainly at the hearing of the appeal Counsel for the employer accepted that the employee had an injury within the meaning of the SRC Act, and further that the employee suffered an incapacity within the meaning of the SRC Act (because he could not drive trucks): transcript page 7 lines 40-46. The Tribunal's use of the word "subsequent" is correct in a temporal sense - the Tribunal found on the material before it that the injury predated the incapacity. While the employer alleges an improper conclusion reached by the Tribunal in respect of the causal nexus between the injury and the incapacity, this is not strictly evidenced by comments of the Tribunal at [69].
45 Second, and as alleged by the employee in the appeal, the primary contentions of the parties in the Tribunal concerned whether the employee had suffered an injury simpliciter to his left shoulder or whether he suffered from a disease, and whether s 7(7) operated to preclude the employee claiming compensation under the SRC Act. So, for example, I note at paragraph [3] of his written submissions dated 25 February 2016 the employee identified issues for determination as:
(a) Whether the Applicant suffered "an injury (other than a disease)" arising out of his employment when, on or about a day in mid to late May 2014, he suffered the sharp pain while holding the gas hose with his left hand at or above shoulder height?
(b) Whether employment, over time but particularly in 2014, contributed to the aggravation of the left shoulder ailment to a significant degree?
(c) Whether those injuries resulted in incapacity for employment at the employee's normal level.
(d) If the finding is that the injury by reason of "aggravation of an ailment" to the exclusion of "injury (other than as disease)" then the further question arises on the Respondent's submission, whether the Applicant made any relevant representation that was both wilfully and false, for the purposes of employment, that he did not previously suffer from a disease, aggravated by the employment in 2014?
46 Further, in written submissions dated 14 March 2016 the employer identified issues for determination as follows:
2. The Respondent notes and respectfully repeats those issues for determination specified by the Applicant in his Submissions at [3(a)] to [3(d)].
3. The Respondent accepts that if the Tribunal concludes that the Applicant has suffered an injury simpliciter to his left shoulder (and not 'a disease', or 'the aggravation of a disease') then the only relevant inquiry will be as to whether that injury resulted in incapacity for work or impairment.
4. If the Tribunal concludes, as the Respondent submits it should, that the Applicant has suffered an ailment and therefore a disease (and not an injury simpliciter), the Tribunal must determine whether that disease was suffered in circumstances that attract the operation of s 7 (7) of the SRCA.
5. In such circumstances, only if it concludes that the provisions of s 7 (7) were not attracted will it be necessary to further determine if the disease resulted in incapacity for work or impairment so as to satisfy the compensable requirement in s 14.
6. As Counsel for the Applicant noted in opening the Applicant's case the above issues, depending upon the facts found, potentially make important the question of whether there has or not been suffered an "injury (other than a disease)".
7. However, significantly for the resolution of the issues in the Respondent's submission, the Applicant's submissions now accept that prior to the relevant period of employment there certainly existed an ailment that became aggravated by subsequent employment events.
8. Thus the condition for which s 14 liability is sought might be (if any):
(a) an "injury (other than a disease)" [often referred to as 'a frank injury' or an 'injury simpliciter']
(b) a 'disease' or the 'aggravation' of a disease
(c) a combination of (a) and (b)
(Footnotes omitted.)
47 Paragraphs [9]-[21] of the employer's submissions related to the nature of the employee's injury. Paragraphs [22]-[36] related to the operation of s 7(7) SRC Act.
48 The manner in which the contentions of the parties focussed on these issues explains to a significant degree the Tribunal's focus on the proper characterisation of the employee's injury. Examining the Tribunal's decision, the Tribunal set out, at [6]-[30], relevant background facts including events relating to the development of the shoulder pain experienced by the employee and the employee's claim for compensation. At [31]-[57] the Tribunal explained, in detail, medical evidence before it. At [72]-[98] the Tribunal considered the nature of the employee's injury, and at [110]-[122] the Tribunal examined the application of s 7(7) SRC Act. This analysis was responsive to the manner in which it appears the parties conducted the case in the Tribunal.
49 Section 14 SRC Act required the Tribunal to determine whether there was a causal link between the injury and the incapacity: Ilsley. This was irrespective of the parties' focus on other issues in the conduct of the proceedings in the Tribunal. However, it is apparent that, in determining the application and considering the arguments before it, the Tribunal at all times had in mind the question whether there was a causal nexus between the injury and the incapacity, as required by s 14 SRC Act. The employer refers to paragraphs [30], [68], [69] and [97] of the Tribunal's decision, and it is useful to revisit them:
30. The Applicant says he kept working on full duties with the Respondent until he was dismissed at the end of July 2014. He says he is still in pain and has not worked since that time because he cannot drive trucks. This is due to his left shoulder being too painful. He does, however, still drive a car. On occasion he also suffers pain in his right shoulder.
…
68. I should say at the outset that I am satisfied, on the balance of probabilities, that the Applicant has suffered an injury to his left shoulder and that this has resulted in his incapacity for work or impairment.
69. As I see the matter, the question of the existence of an injury and subsequent incapacity was not in issue. It was not suggested that the Applicant was fabricating his evidence. Nor was it suggested that the Applicant was exaggerating or overstating the nature of his injury. Indeed, the Applicant was described as stoical by one witness.
…
97. The disease I have identified has led to the Applicant's incapacity, in that he cannot do his usual work, leaving aside the question of his later dismissal. I accept his evidence that he cannot drive trucks, which has been almost his lifelong employment pursuit.
50 While the Tribunal referred to the statutory language of causation in these paragraphs, a fair examination of the Tribunal's broader reasoning demonstrates that the Tribunal had regard to both lay and medical evidence supporting a finding that the employee's inability to drive trucks (that is, his undisputed incapacity) was caused by an ailment aggravated by his employment. I note for example the following observations of the Tribunal referable to that evidence:
79. I am not reasonably satisfied, therefore, that either the late May or the early May incident was the occasion of an injury simpliciter. The evidence seems to suggest a continuing issue in the left shoulder rather than a specific injurious hurt event.
80. Both incidents in May 2014 occur against a background of a number of other events including right shoulder surgery some 12 months before. Following this surgery the Applicant returned to work but continued to experience pain in his right shoulder, especially when lifting hoses. As a result, the Applicant said he was using his left shoulder to do the bulk of the lifting and dragging. The Applicant had previously done this using both arms. Using his left arm involved, of course, left shoulder movement.
81. The Applicant was using his left arm to compensate for a reduced ability to use his right arm. This was due to the right shoulder pain he was experiencing following the shoulder surgery and return to work.
82. This overuse, as I would describe it, in turn caused a flare up, to use Mr Khan's expression, of a pre-existing condition in the Applicant's left shoulder. This was the evidence of Mr Khan. Mr Khan impressed the Tribunal as an orthopaedic surgeon of great experience and ability, whose evidence I should accept.
83. I accordingly find on the basis of Mr Khan's evidence that in May 2014 the Applicant had pre-existing degenerative changes in the left acromio-Clavicular joint and glenohumeral joint. These flared up when he eventually returned to work following right shoulder surgery. This is in accord also with the account given by the Applicant in his evidence.
(Emphasis added.)
51 Later, the Tribunal observed:
87. I am satisfied that, on the evidence, by the end of May 2014 the Applicant had a left shoulder condition best described in the terms set out by Mr Khan. I further conclude that this condition was affected by several incidents occurring in that month. It had, however, already been affected by the Applicant's overuse of his left arm, making up for loss of use in his right arm after shoulder surgery the year before.
88. The conditions described by the medical witnesses, in my view, satisfy the definition of an injury as a disease and, on this basis, the Applicant suffered either an ailment or an aggravation of an ailment which, on whichever basis, is compensable if the provision in section 7 (7) of the Act does not exclude his claim.
(Emphasis added.)
52 The conclusory observation of the Tribunal at [97] concerning the employee's incapacity must be read against the background of the Tribunal's acceptance of the evidence of aggravation of his underlying disease by the employment. It would be artificial to read the Tribunal's reasons in any way other than that the Tribunal accepted the employee's arguments and evidence in support of the causal nexus between his injury and the incapacity. In light of those arguments and evidence, the Tribunal clearly concluded that the employee suffered incapacity for work as a result of a left shoulder condition.
53 The interpretation of the Tribunal's reasons suggested by the employer in this appeal requires an eye finely attuned to the perception of error, contrary to the well-settled approach explained in Minister for Immigration & Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259 at [30]-[31].
