Consideration
24 Counsel for Mr Portors said that no case had considered the intersection between the decision of the Full Court in Hannaford and s 4(3) of the Act.
25 Neither party submitted that I should not follow Hannaford, although the parties differed as to what it meant.
26 In my opinion, the Tribunal did not err in its understanding of Hannaford. The decision stands as authority for the proposition that in relation to its decision-making under, in particular, ss 16 and 19 of the Act, the Tribunal has power to make a finding of fact contrary to a finding of fact made in an original decision under s 14 even where the s 14 decision remains in force.
27 There is little judicial authority on the meaning of s 4(3) of the Act. In Lang v Comcare [2007] FCA 47; 94 ALD 141, Stone J said, at [22]:
For the expanded definition of 'injury' contained in s 4(3) of the Act to apply, there must be three elements: the first is an initial, compensable, injury; the second is treatment for that injury; the third is further injury caused by that treatment.
Comcare v Hill [2005] FCA 657; 87 ALD 501 and Zdziarski v Telstra Corporation Limited [2015] FCA 207; 146 ALD 354 dealt with aspects of the provision which are not presently relevant.
28 It is however relevant to note that s 4(3) is a deeming provision and is therefore required to be construed strictly and only for the purpose for which it is resorted to: Federal Commissioner of Taxation v Comber (1986) 10 FCR 88 at 96, followed in East Finchley Pty Ltd v Federal Commissioner of Taxation (1989) 90 ALR 457 at 478. Equally, as pointed out by Samuels J in Woodlock v Commissioner of Land Tax (NSW) [1974] 2 NSWLR 411 at 414, any facts, or, I would add, conditions as in Lang v Comcare at [22], above, on which a deeming provision is to operate have to exist before the provision takes effect. The judgment of the Court of Appeal in Woodlock v Commissioner of Land Tax [1975] 2 NSWLR 97, reversing the decision of Samuels J, did not affect this reasoning.
29 In my opinion, the purpose of the provision is to make it clear that an injury as a result of medical treatment shall, in the specified circumstances, be itself taken to be an injury without further resort to the definition of that word in s 5A of the Act. The effect of s 4(3) is that consideration of the relationship of the medical treatment itself, as opposed to the original injury, to the employee's employment is made unnecessary.
30 I therefore see no error of law in the Tribunal's conclusions that where an applicant claims to have suffered an injury as a result of medical treatment of an injury, an application under s 54 the Act is necessary, that in the present case there was no such application and the reviewable decision did not encompass that issue. However for the reasons which I give in [31] below, this part of the Tribunal's reasons and the conclusions I have reached in relation to those reasons are not essential to the outcome of the appeal.
31 Although I conclude that the Tribunal did not err in stating, at [96], that any condition arising in the present case out of hernia repair surgery cannot be an injury for the purposes of the Act by virtue of the absence of a workplace-derived hernia condition, I do not accept as legally correct what the Tribunal stated as a qualification to that conclusion. That qualification was that a claim for the hernia repair condition may have been successful if Mr Portors made a separate claim under s 14 for that condition. In other words, if the Tribunal had had before it such a separate claim, in my view it could not have succeeded as a matter of law in light of the Tribunal's factual conclusion that there was no workplace-derived hernia condition. In my opinion, an applicant would have no further entitlement to the payment of compensation for an injury as a result of medical treatment of an injury where it had been found that there was no further entitlement to the payment of compensation for the original injury because it was not workplace related.
32 What I have just considered is the subject of the applicant's application to amend to claim alternative relief. Although that application was opposed by Comcare, it was opposed on the ground that it lacked merit rather than that Comcare suffered any prejudice by reason of it. I allow the application to amend as it seems to me to be no more than technical, framing by reference to the relief sought what was otherwise part of the substantive issues raised in the pleadings of the parties.
33 It is not necessary to consider further Mr Portors' submission that the words "compensation is payable under this Act in respect of the injuries for which the medical treatment was obtained" in s 4(3)(a) operate where there is no more than a decision or determination under s 14 of the Act.
34 It is necessary that I consider Comcare's contention that the Tribunal erred if it reached the conclusion that, despite making a reassessment of the findings of fact on which a decision under s 14 of the Act was made, nevertheless Comcare's liability to Mr Portors under s 14 was preserved. Comcare's submission, as I understood it, was that the word "injury" in s 4(3) refers to injury operating as a matter of ultimate fact, apart from administrative decision making.
35 In my opinion, it is clear that the Tribunal was deciding only the question of Mr Portors' present entitlement to compensation in respect of medical expenses under s 16 and his present entitlement to compensation for incapacity payments under s 19. This was what was decided by Comcare on 8 May 2015 and affirmed on 2 June 2016 by the reviewable decision which refers to "whether present liability exists under section [sic] 16 and 19". This is also apparent from the references by the Tribunal to "no further liability to pay compensation" and "no present entitlement to compensation" in [97] and [98] of the Tribunal's reasons as well as in its decision to affirm the decision under review.
36 However, in my opinion, the Tribunal did not make a legal error in so concluding, contrary to Comcare's contention. First, the Tribunal was dealing with the terms of the reviewable decision and, to that extent, with the terms of the decision made by Comcare on 8 May 2015. Secondly, the Tribunal's approach was consistent with Hannaford, which did not concern prior compensation payments. Thirdly, that the Tribunal found as a fact that the applicant did not ever suffer an injury for the purpose of the Act does not, in my opinion, affect the date on which the Tribunal's decision has effect: compare ss 43(5A) and (5B) of the AAT Act.
37 Fourthly, while I accept, of course, that the concept of an injury is a term of pivotal importance in the Act and that the occurrence of an injury both actuates and defines the ambit of Comcare's duty: Canute v Comcare [2006] HCA 47; 226 CLR 535 at [8] and [37], I do not regard those propositions as having a bearing on the present question. The Tribunal was dealing only with present entitlement and its factual finding did not, in my opinion, mean that, for example, the decision under s 14 had, retrospectively, never had legal effect. Similarly, I do not regard what the High Court said in Military Rehabilitation and Compensation Commission v May [2016] HCA 19; 257 CLR 468 at [52], [57], [62] and [67] as standing for a different proposition. Indeed, in May at [52], the High Court expressly referred to "the tribunal of fact" and to its decision making. Put another way, the High Court did not treat the question of "injury" as a jurisdictional fact.
38 I therefore do not accept Comcare's submission that the finding of fact by the present Tribunal that the applicant did not ever suffer an injury as defined means that any injury suffered as a result of medical treatment could never have been compensable under s 4(3) of the Act, "regardless of the administrative or other status of Comcare's decisions at any particular point in time".
39 Having expressed these conclusions, I now indicate shortly my consequential conclusions as to the matters raised in Mr Portors' notice of appeal and, to the extent necessary, in Comcare's objection to competency and notice of contention.
40 In my opinion, question of law 1 does not arise as the Tribunal did not purport to limit or extinguish any liability of the respondent to pay compensation at any time between 8 October 2002 and 8 May 2015.
41 In my opinion, question of law 2 does not arise for the same reason. Indeed, as I understood it, the submission on behalf of Mr Portors was directed in large part to events subsequent to 8 May 2015.
42 As I have indicated, question of law 3 should be answered "yes".
43 As to Comcare's notice of contention, for the reasons I have given at [36]-[38] above I reject each of the grounds in that notice.
44 As to Comcare's notice of objection to competency, I have accepted the submission that the Tribunal did not have before it a claim of injury as a result of medical treatment but a question of law was involved in reaching that conclusion and consequently the Court had jurisdiction to determine that and the other questions of law I have considered.
