34 His oral evidence revealed him to be an unreliable historian. It seems to me that he was less than frank in his evidence-in-chief. I formed the opinion that his evidence should be treated with care.
35 Mr Sheehan gave evidence in his own proceedings (by way of affidavit, supplementary oral evidence and cross-examination). His evidence was supported by that of his wife, of Senior Constable Muller and of Constable Donaghy-Lewis. He also tended a bundle of expert reports.
36 Mr Sheehan was born on 20 March 1969. He was sworn in as a probationary constable on 9 September 1998. At the time of the derailment, he was stationed at Miranda. He had been transferred from Redfern in about July 1996 at his own request (his evidence was that, by then, he had lost his nerve).
37 Prior to the derailment, Mr Sheehan had also been involved in a number of incidents. Apart from the twisting of a left knee at Redfern Police Station (on 5 December 1995), he was punched in the face (in October 1991) and suffered an injured nose. He was involved in a riot at Redfern (on 29 March 1996) which saw him being punched, kicked, shoved, spat on and having a brick strike the right side of his face. He was attacked by a man wielding a small axe (in December 1996) and received death threats from both the man and his family. He attended a murder scene (on 24 December 1999) and saw the victim who had been shot in the face with a shot gun at close range and was involved in an arrest (on 5 September 2000) during which another officer shot and killed the driver of a stolen motor vehicle.
38 The last of the incidents was followed by a lengthy investigation, the charging of the other officer with murder and his discharge at committal. The process occupied about eighteen months. It was an incident that caused him to feel that, potentially, he too was at risk of being shot.
39 The injury suffered in the riot left him with damage to his hearing and the suffering of tinnitus. Thereafter, his hearing loss deteriorated. He was off work for about four to six weeks during the period from March to May 1996. He came to suffer profound hearing loss in the right ear. In the incident he had also been rendered unconscious and suffered concussion.
40 He underwent unsuccessful ear surgery in April 2003. He settled a claim for hearing loss. His hearing loss led him to be transferred from full operational duties to restricted duties on 30 September 2003 and he was demoted from Leading Senior Constable to Senior Constable. This was a matter of great significance to him. During the period that followed until May 2004, he worked as an exhibits officer.
41 Following the derailment, Mr Sheehan made a report as to injury. The report related to injuries other than those of a mental nature (the inhaling of dust in carriages and the twisting of his left ankle). The first complaint raising the derailment as the cause of psychological problems came to pass when he made a workers compensation claim on 24 May 2004 (exposed to injured and deceased persons). It was at this time that he saw a general practitioner (Dr Schacher) who referred him to a psychologist (Edwina Birch). His claim was referred to Claims Intervention and he was then seen by another psychologist (Ms Costantini). His claim was later declined. He last saw Edwina Birch on 18 June 2004. In the history given to her, she recorded a decision that he had made to seek a medical discharge.
42 Her report, dated 22 June 2004, contained the following:-
"I don't think that I need to see Phillip again. His symptoms have largely resolved, his work situation is not exacerbating any anxieties and is not likely to do so until his medical retirement comes through."
43 He saw Dr Selwyn-Smith on one occasion (there were two reports provided in July and August 2004). He also saw Dr Klug on 20 September 2004. He next saw a psychiatrist on 1 August 2006 (when he saw Dr Maguire at the request of the defendant). He did not seek any treatment until he saw Mr Ian McCombie (a psychologist) in September 2006. He later had a consultation with Dr Phillips on 15 March 2007.
44 In late April 2004, a public servant who had been performing rostering duties was going on maternity leave. A decision was made that Mr Sheehan take her place. He did not want to perform those duties. He wanted to return to operational duties. He enlisted the aid of Professor Fagan to make representations on his behalf. That approach was unsuccessful. He became aware that his hearing loss could not be medically corrected and that he would not be able to return to operational duties (this was said to be regarded by him as devastating). During June 2004, he made a decision to apply for medical discharge.
45 On 23 June 2004, he made that application (because of hearing loss, knee injury and a stress condition). In November 2004, he was found to be unfit to continue in the police force. On 2 December 2004, he was medically discharged from the force.
46 I make similar observations concerning the evidence of Mr Sheehan to those made of the evidence of Mr Wicks.
47 I have earlier mentioned that each plaintiff has given evidence concerning his attendance at the scene of the derailment. This material was presented, inter alia, in their respective affidavits. Largely, this material provides an account of their respective activities at the scene.
48 There are observations of dead and injured passengers (who had been either killed or injured in the derailment). There is no reference to actually seeing passengers either killed or injured. There are observations which can be generally described as concerning risk of the condition of passengers further deteriorating. Nothing is said as to what impact (if any) was had upon them by what had been observed by them.
49 Of the experts, it was originally intended that Doctors Phillips, Klug and Maguire, and Mr Roldan would give oral evidence. Because of constraints of time, a decision was made between Counsel not to call Dr Maguire. A consensus was then reached between them to the effect that no adverse comment was to be made by reason of failure to cross-examine an expert.
50 Dr Klug was the first to give oral evidence. He was not a treating doctor. He saw both plaintiffs in the context of their respective pending applications for medical discharge.
51 In the case of Mr Wicks, he provided a report dated 3 November 2004. It contained, inter alia, the following [at page 7]:-
"In summary, Mr. Wicks has suffered from a chronic post-traumatic stress disorder, now in partial remission, in response to his attendance at the Waterfall rail disaster but also in response to continuing exposure to intense reminders of the Waterfall train disaster. If he suffered a full-blown post-traumatic stress disorder in response to other traumatic incident in 2001, then his PTSD in response to the Waterfall train disaster must be regarded as recurrent. Nevertheless, his psychiatric condition is in direct response to his work as a police officer. It is also partly in response to what appears to be an overt lack of appropriate support and intervention on behalf of his employer. His prognosis is uncertain at this point"
52 In the case of Mr Sheehan, he provided a report dated 24 November 2004. It contained, inter alia, the following [at page 7]:-
"It is clear that Mr Sheehan has been exposed to severe cumulative stresses in the course of his work as a police officer and these are detailed in the body of my report and in the reports of others. I believe he developed a post-traumatic stress disorder.
…
A post-traumatic stress disorder is a severe anxiety disorder in response to, by definition, severely traumatic stresses such as the ones to which Mr Sheehan has been exposed. Self-evidently the Waterfall Train Disaster was the most severe but he had continuing contact with traumatic situations including numerous deaths over a relatively short period of time, which acted as continuing reminders of prior traumas he had witnessed. This is the essential nature of the cumulative way in which such stresses can affect a person. The Waterfall disaster resulted in a PTSD, which may have been recurrent if his symptoms after the Redfern riot were sufficient to qualify for a PTSD."
53 The next expert to give oral evidence was Dr Phillips. Again, he was not a treating doctor. He saw each plaintiff subsequent to the commencement of proceedings.
54 In the case of Mr Wicks, he provided a report dated 14 November 2006. In that report he opined that Mr Wicks may have developed symptoms during 2001 sufficient to warrant a diagnosis of post-traumatic stress disorder. He further opined that it had been exposure to high-level psychological stress at the time of the train accident which tipped the balance and caused him to develop his now chronic psychological symptoms. His report contains, inter alia, the following [at page 10]:-
"The train accident was a very frightening and unusual event. Mr Wicks was one of the first police officers to arrive at the scene. The carnage was considerable with the plaintiff coming across numerous bodies and being confronted by many more people who had substantive physical and psychological in juries. Damage to the forward carriages of the train was very high. The plaintiff remains aware also of the unusual smells at the time (particularly dust) and he was aware of risks of electrocution. The plaintiff was to remain at the accident site for many hours and was responsible for emotionally charged activities including the marshalling and triage of injured persons and collecting/collating the personal belongings of passengers who had been killed or injured."
55 In the case of Mr Sheehan, he provided a report dated 3 July 2007. He came to the view that Mr Sheehan met the criterion for post-traumatic stress disorder. The report contains, inter alia, the following [at page 12]:-
"The causal pathway to Mr Sheehan's psychological disorder is more comprehensive. On my estimation the plaintiff began a process of psychological decompensation from as early as 1992 in the context of the various incidents which occurred from that time. On the balance of probabilities, however, it was the overwhelming magnitude of the carnage at the time of the rail disaster which weakened the plaintiff's psychological status, with symptoms emerging in the period which followed, this also having been the period when his duties were altered. It is not uncommon when assessing psychological trauma to speak about trauma dosage . There should be no doubt that trauma associated with the rail disaster was of extreme dosage or magnitude. In the context of this I find myself holding a different opinion to my colleague Dr Maguire and Ms Constantini who for some reason have placed very high level of emphasis on the plaintiff's change of duties within New South Wales Police. As already stated I believe this issue cannot be ignored but the dosage of physical trauma associated with the change of duties cannot be compared with the dosage of the psychological trauma at the time of the rail disaster. I have summarised details of the plaintiff's experience at the time of the rail disaster in the body of this report and I will not repeat these matters here."
56 The final expert to give oral evidence was Dr Roldan. He was qualified by the defendant and saw both plaintiffs. In the case of Mr Wicks he gave two reports. The second of the reports was dated 30 June 2007. It contained the following [at paragraphs 10.3 and 10.5 respectively]:-
"I also remain of the opinion that on the basis of the available information it seems likely that Mr Wicks developed symptoms of Post Traumatic Stress Disorder in response to a number or work-related stressors during his career with the NSW Police Service and that it is in fact likely that he may have met criteria for the diagnosis of Post Traumatic Stress Disorder following a work-related incident in July 2001.
In my opinion, within the context of the abovementioned pre-existing factors, Mr Wicks exposure to the Waterfall train accident on 31.01.03 is likely to have given rise to a further formal episode of psychological decompensation in the form of Post Traumatic Stress Disorder that has now become rather chronic (albeit fluctuating) and somewhat generalised."
57 In the case of Mr Sheehan he also provided two reports. The second of the reports was dated 25 June 2007. The report contains the following [at paragraph 10.2]:-
"I remain of the opinion that if one were to accept at face value Mr Sheehan's report of the history and symptom attribution, it would be reasonable to conclude that Mr Sheehan developed delayed onset Post Traumatic Stress Disorder as a consequence of his experiences at the scene of the Waterfall train accident in January 2003."
58 He proceeded to opine that there were some impediments to accepting Mr Sheehan's report and symptom attribution at face value when the available evidence was analysed in objective terms. He was of the opinion that Mr Sheehan acted with significant distress to the news (in late September 2003) that he was considered no longer fit for operational duties due to his hearing impediment.
59 He proceeded with the following [at paragraph 10.6]:-
"It is my opinion that the above, together with the stress inherent in his subsequent quest to change the abovementioned decision, plus the stress associated with perceived loss of status, having to perform clerical type duties, having been ordered not to use marked police vehicles or a police uniform outside the police station, having to hand in his police appointments, and the potential loss of opportunities for advancement, are likely to have resulted in the Adjustment Disorder diagnosed by Ms Constantini in June 2004."
60 There was other expert evidence. There were concessions made during cross-examination. For present purposes it is unnecessary to explore these matters.
