(c) Cross-examination of the plaintiff had established him to be an unreliable witness in the sense referred to in Commonwealth of Australian v Diston [2003] NSWCA 51. This unreliability exacerbated the prejudice in (a) and (b), where the only evidence available on a subject was that of the plaintiff.
33 In relation to the loss of documents and witnesses, the defendant has prepared a useful schedule which deals with this issue by reference to topics which would be relevant to the plaintiff's case. By way of illustration, in relation to his Naval service the topics specified are his service before the collision, his activities at the time of the collision and his service after the collision.
34 For the period of Naval service before the collision, Navy records identified persons who served with and in command of the plaintiff. Investigators retained by the defendant have sought to contact those persons by reference to Telstra and electoral records. The results of those inquiries are that most potential witnesses can no longer be located and of those who were able to be contacted, none were able to assist.
35 The plaintiff has criticised this process on the basis that the inquiries were cursory (ie restricted to a telephone call) and no attempt was made to jog the memory of those persons who recalled the plaintiff before the collision by showing them a photograph, or matters of that kind. There is some force in that criticism. Nevertheless, it seems to me to be a matter of common sense that even if much fuller and comprehensive inquiries had been carried out, it is most unlikely that much information would emerge which would be useful and which would stand up to any kind of cross-examination. In any event it does not seem to be in issue that before the collision the plaintiff was performing adequately.
36 Of more importance in relation to this period is that the defendant has an almost complete set of documents relating to the plaintiff which includes his service card, his full Naval health record, his psychological records, his application for discharge, his disciplinary record and all other records, except for his welfare file. While it is conceded by the plaintiff that the welfare file could contain useful information as to his application for a shore posting during the last eighteen months of his service, the other records provide the best and most accurate information concerning his pre-collision service with the Navy. Those records are likely to be far more accurate than forty-year old recollections of individuals.
37 The question of what the plaintiff was doing at the time of the collision and the extent of his participation in rescue and other post-collision activities, is obviously important. One of the usual requirements for a diagnosis of PTSD is that the person suffering from it had been at some personal risk or at least had believed that he was at some personal risk and to a lesser extent that others were also at risk.
38 The defendant's schedule on this issue was compiled in the same way as was the pre-collision schedule. The results have been considerably better. This is not surprising since an event such as the collision is more likely to have remained in peoples' minds than routine service activities which were carried out by the plaintiff before the collision.
39 The schedule reveals that potentially there are ten witnesses who may be able to provide some assistance as to where the plaintiff was and what he was doing. Subsequent to the preparation of the schedule some of those witnesses were interviewed by telephone and the results of those interviews are set out in Exhibit 9, an investigation report from Maxwell Investigations, undated, but which was clearly completed within seven days of the hearing.
40 It is clear from Exhibit 9 that at least potentially some of these witnesses could be of considerable help to the defendant. This is so if they are personally interviewed and efforts are made to jog their memory by reference to the layout of the Melbourne at the time and a photograph of the plaintiff. The defendant also has available a copy of the questionnaire completed by the plaintiff for the Royal Commission dated 25 February 1964 which raises matters which potentially may be adverse to the plaintiff's credit (Exhibit 1). In relation to this period and the post-collision period the defendant also has most of the plaintiff's service records.
41 In relation to the plaintiff's service after the collision until his discharge on 2 July 1970, a similar process of inquiry was made by the defendant through its investigators. Once again the schedule reveals that there were some potential witnesses identified who did recollect the plaintiff. Exhibit 9 includes the following extracts:
"Smith, Anthony James
[address]
Remembers the plaintiff and his appearance as a short stocky bloke with black hair.
The plaintiff seemed quiet and reserved.
No apparent injuries but can't comment on his emotional status as can't remember that.
Generally did not live with them.
The atmosphere was stressful as a lot was always expected of the men who lived in rough or bare conditions.
Other blokes who were in the plaintiff's group were Morse, Robbie Robinson, Mike Kielty, Carroll, Bob Bailey.
I have a pretty good memory and am willing to assist if required."
"McCarthy, Terry
[address]
Remembers the plaintiff in the Navy (Yarra) and afterwards as they worked together selling the pink pages telephone directory. He said the plaintiff never changed, there was nothing wrong with him. Willing to assist the AGS if required."
42 Another topic specified in the schedule is the absence of any recollection on the part of medical practitioners who treated, or may have treated the plaintiff, while he was in the Navy. Not surprisingly, none of them can remember the plaintiff. As indicated, the defendant does have available the plaintiff's complete medical file. That would seem to me to be the best evidence of any medical treatment and complaints which he made to doctors whilst in the Navy. Given the nature of his condition and his evidence that he has never sought medical treatment for it, in particular never sought any psychological or psychiatric treatment, the absence of recollection by Naval medical practitioners would seem to be quite peripheral to the issues likely to be raised at trial.
43 In relation to the plaintiff's Naval service after the collision two important documents were put to him in cross-examination. The first was a letter from him to his commanding officer requesting a discharge so that he could stand as a member of parliament (Exhibit 4). On one view of it, that letter supports matters raised in his affidavit but there are other matters in it which might place quite a different complexion on that affidavit material. There is also a medical report which although it confirms that after the collision the plaintiff was complaining of sleep walking, also refers to his wife becoming hysterical (she having lost her father on the Voyager) when he went to sea (Exhibit 5). At least potentially these matters provide useful material for cross-examination to test the plaintiff's assertions.
44 A matter to which I can have regard is the fact that this Court has heard a number of cases brought by members of the crew of the Melbourne against the Commonwealth. Some, but not all, have proceeded to judgment. The judgments are available. The judgments contain a recitation of the facts and competing submissions. It seems to me that the information available to the defendant concerning the plaintiff's Naval service both before, during and after the collision in this case is significantly greater than in most of the cases which have proceeded to judgment in this Court.
45 Leaving aside that consideration, however, and focusing purely on the facts of this case and the information which is now available and which is potentially available when the identified witnesses have been properly interviewed by the defendant, I am satisfied that the loss of the welfare file, the degradation of the memory of some potential witnesses and the unavailability or absence of other witnesses is not such as would prevent a fair trial taking place from the defendant's point of view.
46 The defendant submits that it has been seriously prejudiced when dealing with the plaintiff's claim for past economic loss after his discharge from the Navy, because the claim involves a period of thirty four years but there are tax returns or tax assessments for only seventeen of those years. In particular the defendant points to the period from 21 August 1978 to 13 March 1988 when the plaintiff was self-employed. There are no tax returns for that period and the only particulars of earnings is a range of between $130 - $500 after tax. In his evidence the plaintiff says that this range of earnings and the other amounts set out in para 13 of his affidavit, which are not supported by taxation records, were derived by him by a process of estimation.
47 This forms a significant part of the plaintiff's claim. The defendant's complaint is that the only evidence on this subject will be that of the plaintiff and the defendant will not, except in one respect to which I will refer, be able to test his unsubstantiated assertions. The defendant accepts that in relation to some other years for which there are no taxation records, there are bank statements and deposit books available which may provide a somewhat fuller picture, but there is no evidence that these documents are comprehensive and complete. Even taking those documents into account, there is a period of ten - twelve years for which no documentation is available to support a claim for past economic loss.
48 During 1979 the plaintiff was engaged in Family Court proceedings relating to the maintenance and custody of the three sons of his first marriage. The Family Court file was produced to the court. From that file the defendant tendered Exhibit 6, being an affidavit by the plaintiff sworn on 11 July 1979. Included in that affidavit is a statement by the plaintiff of his pre-taxation earnings for the year ending 30 June 1978. They show earnings of approximately $470 per week. When that material is compared with his estimate for that year of $150 per week after tax, it is clear that the estimate is not only incorrect it is incorrect by a significant margin.
49 The defendant points to that discrepancy to support its argument that it is unfair for the matter to go to trial with the evidence in this state since in this instance at least, the plaintiff's estimate of his earnings is plainly and significantly wrong. The plaintiff freely conceded this when the affidavit was placed before him.
50 The existence of the Family Court material, and in particular the affidavit Exhibit 6, cuts both ways. On one approach it provides clear evidence of the unreliability of the plaintiff's estimates of earnings where those earnings are not substantiated by tax or other records. At least potentially that material when produced at the trial would place doubt on all of the plaintiff's estimates, unless the plaintiff could substantiate them. Rather than demonstrating an element of unfairness if the matter were allowed to proceed, this affidavit potentially provides a powerful argument for the defendant at any trial to discredit the plaintiff's unsubstantiated estimates of earnings.
51 In personal injury matters it is unfortunately not unusual for there to be little or no substantiation for claims for economic loss. This has never been accepted as a reason for why the courts should not attempt to do justice between the parties by doing the best they can to make an appropriate assessment. (State of NSW v Moss (2000) 54 NSWLR 536.) It follows that I am satisfied that the absence of documentary substantiation for part of the plaintiff's claim for past economic loss will not prevent a fair trial taking place.
52 The medical records of the plaintiff which are currently available are his Naval records until July 1970, those of Dr Bayly, a general practitioner, for the period 1982 - 2000, of Dr Chuih, general practitioner 20001-2003 and various specialist reports in the specialities of ophthalmology and cardiology between 1986 and the present time. Except for the 1970's, the defendant has available quite a comprehensive set of medical records.
53 In para 19 of his affidavit, the plaintiff identified to the best of his ability every medical practitioner who treated him since he left the Navy. In his evidence he added an additional doctor to that list, bringing it up to eighteen. I do not regard this as a significant matter of prejudice for the defendant. As with the plaintiff's post-collision service in the Navy, he has consistently stated that over the years he has not sought psychiatric treatment, or treatment generally in relation to the disabilities which he now seeks to attribute to the collision. Such medical records, therefore, would be unlikely of their nature to be of assistance to either party. To the extent that medical records do exist, they confirm problems which the plaintiff had with alcohol and tobacco abuse. There also appear to be reports from a Mr O'Neill, psychologist, in the Family Court file which was produced to the court. They were not tendered, but they exist. Whether those reports relate to the plaintiff or to his children or to his first wife I do not know, but the existence of such material which relates to 1979 can only assist the defendant.
54 In relation to the plaintiff's unreliability the defendant referred the court to the following matters.
