37 The claim about witnessing the Sea Venom incident first emerged during the hearing before the Veterans' Review Board on 18 September 1998. The applicant firstly described the general tension of operational service in Vietnam at the time, and how a landing aircraft went over the side of the deck and the pilot drowned. It then took some time before the Sea Venom incident was able to be confirmed as having occurred at all. When the review of the decision was first before the Tribunal, the applicant's counsel described the applicant as having witnessed the aircraft toppling over the side of the ship and the pilot being unable to escape from the cockpit. The applicant's evidence was that seeing the person trying to punch his way out of the canopy whilst the aircraft was still floating was very disturbing. He said he was affected because he saw a person 'fighting and struggling and trying to save their own life and they had no show' and he could do nothing about it. He said the helplessness of being merely a bystander was disturbing.
38 In my judgment, the Tribunal has accurately identified the hypothesis put forward by the applicant, namely his seeing the pilot (or a crew member) unsuccessfully struggling to escape from the cockpit of the Sea Venom when it had fallen into the sea caused, or aggravated, his diseases.
39 At the time of the first Tribunal hearing, the Tribunal concluded:
'All of the material points to his having witnessed an event that involved actual and threatened death to those on board the Sea Venom. It does not point however to Mr Hill's having a response that involved intense fear, helplessness or terror.'
40 The Tribunal made those findings, noting that the applicant's recollection was inconsistent with the historical records of it. It found, alternatively that the truth of a fact inconsistent with certain hypotheses had been proved beyond reasonable doubt, namely that the applicant did not see a person trying to get out of the aircraft as it sank.
41 In the first Hill decision, von Doussa J said at 303 - 304, [36]:
'The respondent under s 120(1) carried the burden of establishing that the relevant fact did not occur. The relevant fact in this case would be that the veteran had experienced, witnessed or been confronted with an event that involved actual or threatened death or serious injury, or that the veteran's response involved intense fear, helplessness or horror.'
His Honour did not regard the finding that there could not have been any person trapped under the canopy of the aircraft as described by the applicant as disproving those facts, but simply as demonstrating that the applicant's perception on a matter of detail would be wrong.
42 Assuming that the 1994/1995 PTSD SoP was the one to be applied, and assuming the hypothesis was reasonable the ultimate question under s 120(1) for the Tribunal was whether it has been proved beyond reasonable doubt that the applicant did not, in the Sea Venom incident, experience a stressor, that is whether he did not experience, witness or be confronted with an event which involved actual or threatened death or injury to others, and whether he did not have a response involving intense fear, helplessness or horror in the manner he asserted. Under the alcohol abuse SoP, the relevant question was whether it had been proved beyond reasonable doubt that the applicant did not, in the Sea Venom incident, experience a stressful event, that is whether he did not experience an incident in which there were external stimuli that would result in psychological stress, and where there were subjective symptoms of increased stress in the manner he asserted.
43 The Tribunal's reasons are not satisfactory. It did address the hypothesis put forward by the applicant under s 120(3), having regard to the two SoPs identified. It found the hypothesis was not reasonable, on the basis of findings of fact. That was erroneous. But, immediately before its conclusion in relation to the SoPs, it made a finding of fact. It was satisfied beyond reasonable doubt that the applicant 'did not see the Sea Venom incident'. It noted the medical evidence was that his recollection of the incident is 'probably a compilation of his traumatic dreams and reality'. If the hypothesis the applicant put forward was (as he said) that he saw the Sea Venom incident then, even if his recollection about its details were erroneous, a fact upon which the hypothesis was based would have been disproved beyond reasonable doubt. The essence of the claim was that he saw a person unable to escape and unable to avoid drowning in the incident, and that he was affected by what he saw. In my view, the Tribunal has found beyond reasonable doubt that the applicant did not see what he now recalls having seen in that essential respect.
44 I confess to some unease in coming to that conclusion about what the Tribunal found. The Tribunal noted the medical evidence that the applicant's memory is probably partly a compilation of reality, as well as his dreams. It does not, however, explain what it understood by that evidence. Whilst rejecting the applicant's evidence about the details of what he saw, it does not expressly eliminate beyond reasonable doubt that he saw or experienced some part of the incident, even if he was physically unable to have seen the aircraft run off the deck. The Tribunal does not explore where he might have gone in the 30 seconds or so whilst (on its findings) the ship passed the aircraft then in the sea, or what might then have been seen of the crew member who had only (it found) belatedly ejected and was about to drown.
45 However, such matters are matters for the Tribunal. Its reasons for decision are to be read sensibly and not with an eye attuned to the perception of error: Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259 at 271 - 272. I think its general finding, beyond reasonable doubt, that the applicant did not see the Sea Venom incident is a finding that the applicant did not, as he claimed, see the pilot or a crew member of the aircraft somehow struggling unsuccessfully to survive. That is not a matter of detail. Taking the hypothesis as broadly as possible, it involves the applicant claiming to have seen something like that and feeling both horror and helplessness at his inability to assist. The Tribunal's finding, in my judgment, is that he did not see something like that. As its finding was made beyond reasonable doubt, s 120(1) means there was no sufficient ground for making the determination.
46 Finally, counsel for the applicant contended that the Tribunal had erred in law because it could not, on the evidence, have been satisfied that the applicant did not see the Sea Venom incident (or at least some part of it). Clearly, there is no error of law in making a finding which is open to debate, or even one which is against the apparent weight of the evidence: Collins v Minister for Immigration and Ethnic Affairs (1981) 58 FLR 407 at 410 - 411; Repatriation Commission v Thompson (1988) 44 FCR 20; Willcocks v Comcare (2001) 66 ALD 119. Indeed, there is no error of law simply in making a wrong finding of fact: Waterford v The Commonwealth (1987) 163 CLR 54 per Brennan J at 77.
47 The question of whether there is any evidence of a particular fact is a question of law: Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 per Mason CJ at 355 - 356. So too, as Mason CJ there said, is it a question of law whether a particular inference can be drawn from facts found or agreed. Hence, his Honour concluded:
'Thus, at common law … want of logic is not synonymous with error of law. So long as there is some basis for an inference - in other words the particular inference is reasonably open - even if that inference appears to have been drawn as a result of illogical reasoning, there is no place for judicial review because no error of law has taken place.'
48 The applicant's contention is that the finding of the Tribunal beyond reasonable doubt that the applicant did not see the Sea Venom incident is 'perverse'. The conclusion was drawn from primary evidence. I take the submission to be that the conclusion was not reasonably open to the Tribunal on the primary facts which it found.
49 The submission is more difficult to consider by reason of the reverse criminal onus of proof imposed by s 120(1) of the VE Act. The task is not simply to determine whether there was evidence from which the Tribunal could make its primary findings of fact about what happened in the Sea Venom incident, and its conclusion, on the balance of probabilities. The primary findings of fact appear each to be significant to the consequential conclusion, expressed to be beyond reasonable doubt, that despite his evidence the applicant did not see the Sea Venom incident. It was the detail of those primary findings, and their inconsistency with the evidence of the applicant on those details, which largely led the Tribunal to its consequential conclusion.
50 The Tribunal referred in some detail to the evidence it received about the Sea Venom incident, including statements of the pilot of the aircraft and of an observer in a rescue helicopter responsible for observing aircraft landings at the time, as well as the material contained in a report from Commodore Mulcare on HMAS Yarra, following the HMAS Melbourne. Commodore Mulcare's report contains further statements confirming a crew member ejected the canopy of the aircraft, and that both the pilot and the crew member ejected from the aircraft. One witness describes the pilot as 'floundering' and another as 'splashing in the water'. All witnesses described the crew member as lying inert, face down in the water, before sinking below the surface. The observer in the helicopter was a little vague about where the crew member had landed after ejecting, except to say that he was in or in line with the splash of the aircraft. The pilot of the helicopter also saw both the pilot and crew member eject from the aircraft, and described the crew member then as 'floating inverted and vertical amongst the wreckage with his parachute deployed'. In the confusion of the moment, precise and accurate recollection of detail on the part of the applicant (or others), is not necessarily to be expected. There is some scope in that material to have tied the applicant's observations of the crew member (as he described them) to the position of the crew member in or in the vicinity of the wreckage of the aircraft, and to have been confused about which of the pilot or crew member was floundering. However, the evidence clearly points firmly to the canopy of the aircraft having been ejected by the crew member, and of both the pilot and the crew member having operated their ejector seats by about the time that the aircraft hit the sea.
51 Counsel for the applicant also pointed out that a report of a board of inquiry into the Sea Venom incident dated 29 April 1966 (the day after the Sea Venom incident), concluded that the crew member did not use the ejector mechanism, and that:
'He was either injured on impact and therefore unable to release himself or he tried to extricate himself while in the water and failed. There is no firm evidence that the observer tried to eject before impact.'
As is apparent from that report, it was prepared on considerably less detailed information than the report prepared some time later by Commodore Mulcare at the behest of solicitors for the respondent. Commodore Mulcare also addressed the capacity of the applicant to have seen the Sea Venom incident. Given his location at the time, he said that the applicant would not have had sufficient time to have moved from his work position to see the aircraft run over the edge of the flight deck. He does not assert that there would not have been time for the applicant to have then moved to a position where he could have seen the wreckage of the aircraft in the sea, and indeed another witness was able to move from the sick bay area below the flight deck to a position where he did see the aircraft wreckage passing alongside the ship. However, the Tribunal accurately noted Commodore Mulcare's evidence, namely that the applicant could not have seen the flight deck or the aircraft go over the end of the flight deck. The Tribunal has not drawn from that evidence that the applicant could not have seen the wreckage of the aircraft in the sea.
52 Moreover, there was additional information to which the Tribunal referred. That included the fact that the applicant did not mention the Sea Venom incident when he first made his claim in September 1997, or until his evidence before the Veterans' Review Board in September 1998. It included the reference to the medical evidence as to how the applicant may have come to believe that he saw the Sea Venom incident in the way in which he described it although he had not done so, and tied with that medical evidence was the further information that the applicant had on 12 February 1966 witnessed a Gannet aircraft run off the flight deck of HMAS Melbourne and hang precariously by the arrestor wire over the side of the ship for some little time. Consequently, the Tribunal concluded that the applicant had confused the Sea Venom incident with the Gannet incident.
53 Even though another decision-maker may not, on the whole of the material, have been persuaded beyond reasonable doubt that the applicant did not see the Sea Venom incident as he described, and in particular did not see that which, taken broadly, I have identified as the hypothesis raised by the material he presented, I am unable to conclude (as counsel for the applicant urged) that the Tribunal's satisfaction beyond reasonable doubt that the applicant did not see the Sea Venom incident was 'perverse'. The weight the Tribunal gave to particular evidence was a matter for it. It has not been shown to have misapprehended the reverse criminal onus of proof imposed by s 120(1) of the VE Act. In my judgment, it has not reached a conclusion which was not reasonably open to it on the evidence.
54 The question the Tribunal answered involved addressing whether a fact upon which the applicant's claim was made was disproved beyond reasonable doubt. The fact that it erred in addressing the decision-making steps does not mean that, within its process, it has not happened to address the ultimate question. In my judgment, it has done so.
55 Accordingly, notwithstanding the errors of law in the Tribunal's approach to which I have referred, it has in a way which is adversely decisive of the applicant's claim addressed a final step in the process in a correct manner. That is sufficient for the application to fail.
56 I do not consider the application of the 1999 PTSD SoP could make any difference to the outcome. It relevant differs from the 1994/1995 PTSD SoP in two respects. Firstly it uses the expression 'severe stressor' rather than 'stressor' in the description of the factors that as a minimum must exist before it can be said that a reasonable hypothesis has been raised connecting the applicant's PTSD with the circumstances of his service. Secondly, although the definition of 'experiencing a severe stressor' is in essence the same as par (a) of the definition of 'experiencing a stressor' in the 1994/1995 PTSD SoP, par (b) of that definition is removed, and examples of stressors are given. There is no doubt that, under the 1999 PTSD SoP, observing the Sea Venom incident would amount to witnessing a severe stressor. The same issue would nevertheless arise: once the hypothesis of the applicant was accepted as reasonable, has it been shown beyond reasonable doubt that a fact upon which the hypothesis is based (that the applicant did see the Sea Venom incident) did not exist. The finding of the Tribunal is that the applicant did not see the Sea Venom incident, including the way in which the crew member died.
57 For those reasons, in my view the application must be dismissed. I so order.
