56 I accept that it is the applicant's recall that he first became aware of the suggested link between the collision and his symptoms when he read Dr Troup's report. The report set out the association between the two in a comprehensive way. I think, however, that the probability is that the applicant became aware of Dr Troup's opinion (that he was suffering from a psychiatric illness arising out of the Melbourne/Voyager collision) prior to the date of her report, probably in July 1999 during the course of consultations with her. This is consistent with the statement that he made in the application for a pension and accords with the logic of events. Dr Troup's report drew on material presumably obtained by her in the course of consultations prior to the date of its preparation. She does not record the date of any consultation with the applicant. A worksheet annexed to the report is dated 20 August 1999 and evidences that she had obtained a history from the applicant on or before that day.
57 I am satisfied that the applicant was unaware of the connection between the Melbourne/Voyager collision and the symptoms which he reported and which Dr Troup diagnosed as constituting generalised anxiety disorder (and secondary dysthymic disorder) until around July 1999. The present application is one made within three years after the applicant became aware (or ought to have become aware) of all three matters listed in
s 60(1)(a)(i) - (iii).
58 I now turn to a consideration of s 60G(2) and to the separate question of whether the applicant has succeeded in establishing that it is just and reasonable to extend the limitation period to permit him to bring his claim.
59 In Holt v Wynter [2000] NSWCA 143; 49 NSWLR 128 Sheller JA (in a judgment with which Meagher JA, Handley JA and Brownie A-JA concurred) observed that the effect of the decision of the High Court in Brisbane South Regional Health Authority v Taylor (1986) 186 CLR 541 is that an application for an extension of time under the limitation legislation should be refused if granting it would result in significant prejudice to the potential respondent. In the Commonwealth's submission this is such a case.
60 Causation would be a central issue at any trial. The Commonwealth submits that it is deprived of witnesses who can provide observations of the applicant dating back to the period before the collision (and in the years shortly thereafter). This would be relevant to a determination of the link between his abuse of alcohol and cigarettes, to take two examples, and any claimed psychiatric injury following the collision. The Commonwealth notes that after the passage of more than forty years it is unrealistic to expect that the applicant's shipmates might have any recall of his conduct. The service records, consistent with the applicant's case that in the period after the collision he commenced to abuse alcohol, might bear a different interpretation if the circumstances surrounding each incident were known.
61 The Commonwealth identified the inability to locate witnesses who might be able to comment on the applicant's father's drinking patterns to be a further item of prejudice. It is deprived of the ability to explore the link between alcohol abuse and genetic factors.
62 It was contended that witnesses who knew the applicant at the time he commenced smoking might be in a position to comment on his smoking habits: whether he presented as an ordinary social smoker.
63 On the Commonwealth's behalf, considerable reliance was placed on the judgment of McHugh J in Brisbane South Regional Health Authority. His Honour, dealing with the extension provisions under the Limitation of Actions Act 1974 (Qld), emphasised that an applicant who satisfies the preconditions does not acquire a presumptive right to an order extending time. The applicant who satisfies the conditions is entitled to ask the court to exercise a discretion in his or her favour, but it remains for the applicant to demonstrate that it is just and reasonable to do so. My attention was directed to his Honour's observations at 551 concerning the rationales for the existence of limitation periods that:
"Sometimes the deterioration in quality is palpable, as in the case where a crucial witness is dead or an important document has been destroyed. But sometimes, perhaps more often than we realise, the deterioration in quality is not recognisable even by the parties. Prejudice may exist without the parties or anybody else realising that it exists. … Similarly, it must often happen that time will diminish the significance of a known fact or circumstance because its relationship to the cause of action is no longer as apparent as it was when the cause of action arose. A verdict may appear well based on the evidence given in the proceedings, but, if the tribunal of fact had all the evidence concerning the matter, an opposite result may have ensued."
64 I do not consider the absence of witnesses able to comment on the applicant's drinking, cigarette smoking and general character prior to and after the collision while he remained a member of the RAN to give rise to significant prejudice to the Commonwealth in defending the claim. The applicant joined the Navy as a sixteen-year old youth. He was still below the legal age for drinking at the time of the collision. That his consumption of alcohol should, by and large, post-date the collision is unlikely to be a matter of moment. The applicant agreed in evidence that he had smoked while in the Navy, offering as one reason for doing so that cigarettes were available to seamen duty free. I consider it somewhat fanciful to think that the Commonwealth might defend that part of his claim by which he asserts his cigarette smoking to be causally linked to psychiatric injury by leading evidence that as a youth he appeared to be a social, as distinct from an anxious, smoker.
65 In evidence, the applicant acknowledged that the account he gave to Mr Wilks of his drinking in the period after the collision was accurate: "drinking ashore with other sailors c. twice per week, two or three pots of beer at a time" (Robert Wilks' report, 19 September 2001). The applicant's case is of increased drinking as time went by. I do not consider the inability to call evidence relating to the circumstances in which the applicant came to notice for disciplinary offences committed while drunk to constitute any real prejudice to the Commonwealth. Should his claim proceed, the applicant will no doubt invite the Court to draw an inference from the frequency with which he came to official notice in connection with drinking that he was exhibiting symptoms of alcohol abuse consistent with the psychiatric injury that he claims. This would be an available inference whether an examination of the circumstances of each incident revealed it to be an instance of lone, morose drinking or of high spirited social drinking with young shipmates.
66 The history given to Mr Wilkes relating to the applicant's father's drinking pattern may be significant to a case that any excessive alcohol consumption is likely to be explained by genetic factors. The fact that the father had a problem with alcohol is acknowledged and may be commented upon. The inability to lead evidence as to the nature and extent of Mr Fullarton senior's drinking pattern does not impress me as amounting to prejudice to the Commonwealth in defending the son's claim.
67 The applicant's service records include the results of medical examinations undertaken when he was an applicant for a diving course and for becoming a sub-mariner. As the Commonwealth submits, after this interval of time there is no prospect that the various naval surgeons who examined the applicant would have any recall of him. On his application to become a sub-mariner the applicant was assessed as being emotionally stable. The doctor ticked a box to signify so much. The Commonwealth submits a bare record of this sort might be thought to have little weight, whereas closer to the time the doctor may have been in a position to give a detailed account of why he had come to this opinion. The examination was a general medical one and it is not suggested that the practitioner was qualified to or did carry out any psychiatric assessment. It is not suggested that the plaintiff was exhibiting frank symptoms of any psychiatric condition at the time.
68 The Commonwealth's solicitors have, with the assistance of a firm of private investigators, endeavoured to locate persons who served with the applicant when he was a member of the RAN. A number of names were furnished by the applicant of people who could give an account of him at this time. Only two of the persons contacted appear to have any recall of the applicant. Mr Summerton, the Petty Officer, whom the applicant recalls as informing him of the disaster, was contacted. He is reported to have responded, "My memory is bad. I can recall details of my childhood but not later parts of my life." For the reasons earlier given I am not persuaded that the absence of witnesses who remember the applicant, either on board the HMAS Melbourne on the night of the collision, or more generally during his period in the RAN, constitute significant prejudice to the Commonwealth. The applicant was a youth at the date of the collision. The recollections of his superiors or shipmates as to his character and habits in the relatively short period of his service are not likely to be significant to the determination of the issues raised by his claim.
