Evidence before the Tribunal
13 The Tribunal examined the medical reports before it in detail. A number of these reports, including the reports of Dr Jamieson, Dr Safier and Dr White, concerned orthopaedic issues and are not relevant to any pre-existing mental condition of the applicant. So far as relevant to the proceedings before me the Tribunal considered:
· two reports dated 19 November 2001 (as the Tribunal noted, in light of the chronology of events presumably "2001" was a typographical error and the correct year was 2002) and 11 March 2003 prepared by Ms Lynette Jooste, a psychologist. In her first report, which was to the referring medical practitioner, Ms Jooste diagnosed the applicant as suffering from PTSD, depression and panic attacks. In her second report, which was to the Trustee, Ms Jooste noted that the applicant had reported being diagnosed with schizophrenia after a psychotic episode four years prior, and that the applicant suffered from a mild intellectual disability. Ms Jooste also confirmed her previous diagnosis of the applicant as suffering from PTSD with depression, a dog phobia and panic attacks, but concluded that:
"With suitable counselling and therapy, Mr Edington should make a full recovery from the traumatic effects of the Rotweiler Incident. His original condition, schizophrenia, the mild mental retardation, and low working skills would continue as before."
· a report to the Trustee dated 2 April 2003 prepared by Dr Johnn Olsen, a consultant physician in occupational and environmental medicine. Dr Olsen's report dealt primarily with the physical impact on the applicant of the event involving the dogs. Dr Olsen noted the applicant's schizophrenia under the heading "Diagnostic Assessment", and discussed the impact of that condition on the applicant's overall condition following the events involving the dogs, including as follows:
"5. YELLOW FLAGS
Yellow flags refer to factors that may be associated with a risk that the person will develop chronic musculoskeletal pain which is either out of proportion to the degree of injury or a negative long term sequelae that results in a chronic pain syndrome where the pain is no longer simply mediated by the tissue damage associated with any accident.
.....
Whilst I would not necessarily consider schizophrenia to be a yellow flag, it has a net effect which is exactly the same. It was readily apparent to me that Mr Edington is truly struggling to deal with the event that involved his incident including his fright at the prospect of being attacked by two Rottweilers, although he was not, and also the subsequent events in which he was left without assistance and his trust took a considerable set back.
In my opinion Mr Edington has decompensated and although he remains on a major tranquilizer for his schizophrenia and although there were no profound outwards indications of instability in his schizophrenia his reluctance and in the end non acceptance of further investigations including a bone scan is in my opinion a clear indication of his mental state. I was concerned that I may miss an undisclosed fracture by not performing the bone scan. In the final analysis however my opinion will not depend on the bone scan and therefore I consider it reasonable to not proceed with that investigation."
Dr Olsen also noted that the applicant only required ongoing treatment for his schizophrenia and, in his opinion, he would benefit from psychiatric intervention to help him deal with the set back that he had sustained in the accident.
· two reports to the Trustee, one dated 3 May 2003 and another undated but from early 2006, prepared by Dr JG Reddan, a consultant psychiatrist. In her first report Dr Reddan observed that:
o the applicant stated that he had been told that he suffered from "a phobia" and "post-traumatic stress disorder" and that he should be having treatment for his condition
o the applicant had stated that his psychiatric history was of absolutely no relevance, and refused to discuss the matter further. Dr Reddan also noted that the applicant was very guarded and defensive about his psychiatric history
o the applicant's longitudinal history and presentation suggested that he suffered from schizophrenia, and that, although he was hospitalised on one or more occasions, the more overt psychotic symptoms had been reasonably well controlled on medication
o she agreed with Dr Butler that the applicant's self-report and presentation did not support a diagnosis of PTSD. Dr Butler said that, although the applicant described some anxiety around dogs, in order to make a diagnosis of a specific phobia there must be evidence of a persistent and irrational fear of a specific object, activity or situation, and in this case it was debatable whether the applicant's anxiety about dogs was irrational
o she disagreed with Ms Jooste that the applicant suffered either an intellectual disability or mental retardation
o she was unable to provide a detailed history of the course of the applicant's schizophrenia as the applicant refused to provide any history and Dr Butler's report did not provide detail of the applicant's past history
o the applicant's reported anxiety about dogs would not prevent him from returning to work and represented a relatively mild impairment which was not permanent. However Dr Reddan considered that the applicant would be permanently unable to perform duties as a field assistant, most significantly because of the residual symptoms of schizophrenia.
In her second report from early 2006, Dr Reddan stated that she had read a report dated 9 May 2003 by Dr Jamieson, a letter dated 15 July 2004 by Dr M Safier, reports dated 17 July 2003 and 15 July 2004 by Dr J Butler, and a report dated 22 October 2005 by Dr E de Leacy, however that additional material did not cause her to alter the opinions expressed in her report of 3 May 2003.
· three reports to the Trustee dated 13 January 2003, 17 July 2003 and 15 July 2004 by Dr Jeremy Butler, who was identified by the Tribunal as the applicant's treating psychiatrist. In the first report, Dr Butler described the primary psychiatric diagnosis as "Schizophrenia paranoid sub type with ongoing residual negative symptoms". Dr Butler described the second diagnosis as pertaining to:
"an anxiety disorder which resulted from the unfortunate incident whilst working as a Field Officer in Fire Ant Surveillance. Subsequent to that incident he has suffered from some phobic anxiety with relation to exposure to dogs and has experienced some avoidance... I have taken his history several times regarding this matter and I do not believe that he has suffered from a fully fledged post traumatic stress disorder..."
Dr Butler's third diagnosis related to substantial damage to the applicant's leg/ankle also arising from the incident with the dogs
In his second report, Dr Butler noted that he had read all the reports by doctors Olsen, Reddan and Jamieson regarding the applicant's symptomatology and disability, that he had ongoing concerns about the process of the applicant's discontinuation of his employment, and confirmed his earlier diagnosis.
In his third report, Dr Butler said:
"I maintain the view that I expressed [in his original report dated 13 January 2003] that the major cause of the immediate disability was the anxiety and physical symptoms directly related to the dog attack and that his schizophrenic illness was a secondary issue.
...
With respect to this, I believe that the disability prohibiting his unemployment was not directly linked to a pre-existing condition and has subsequently proved to be a largely temporary impairment..."
· a report to the applicant's solicitors dated 22 October 2005 by Dr Eric de Leacy. In compiling his report, Dr de Leacy had reference to reports of Ms Jooste and doctors Olsen, Jamieson, Butler, Safier, and Reddan. Dr de Leacy observed that the applicant suffers schizophrenia, but also a high level of anxiety, an intense fear of dogs, and, in Dr de Leacy's view, PTSD. In particular Dr de Leacy said the applicant had:
"a range of symptoms that fulfil the DSM IV criteria for Post Traumatic Stress Disorder by a having (sic) the requisite number of symptoms from each category of intrusive symptoms, avoidance symptoms and hyperarousal symptoms. He thus he endorsed (sic) the following intrusive, recollective, experiencing symptoms including having recurrent and intrusive distressive recollections of the event including images thoughts or perceptions, having recurrent distressing dreams of the event, acting all feeling (sic) as if the event were recurring at various times including having flashbacks to the event, having intense psychological distress on exposure to cues that symbolise the event and having intense physiological reactivity on exposure to such cues. He also endorses avoidance phenomena such as avoidance of thoughts and feelings associated with the event, avoidance of places and people associated with the event...he does however not have any amnesia of the event, he has marked diminition of interest in activities since the event..."
Dr de Leacy went on to diagnose the applicant as suffering from chronic schizophrenia paranoid type, and chronic PTSD. He considered an alternate diagnosis as a specific phobia with respect to dogs, but considered there was less merit in this diagnosis and that a more appropriate diagnosis was PTSD because of the severity of the symptoms. Dr de Leacy noted that:
"A person suffering a phobia would not experience the level of intrusive, re-experiencing and recollection time symptoms that Mr Edington does. Someone with a phobia would be more likely only to have avoidance symptoms. Additionally a phobia is by definition an irrational fear and in this case the fear is not irrational."
Dr de Leacy noted also that, prior to the dog incident, despite his schizophrenia the applicant was actually able to work, and that his inability to work subsequently was due to the stress produced from the dog incident and was not related to his schizophrenia, which had not changed in recent years.
In relation to possible interrelationship of PTSD and the applicant's schizophrenia, Dr de Leacy said:
"9. Post Traumatic Stress Disorder is a condition that is quite separate from Schizophrenia. There is no direct correlation between the two conditions. There is no reason why a person with schizophrenia and (sic) should not develop Post Traumatic Stress Disorder if exposed to sufficiently severe stressful event.
10. It is conceivable that schizophrenia may have made Mr Edington more susceptible to Post-Traumatic Stress Disorder. Earlier in this report I stated that Criterion A requires the person perceives that here he is fear (sic) for his life and this perception would depend on many factors. A person who has a past history of paranoia might be more prone to fear and panic in dangerous situations. Mr Edington has cognitive slowing and would not be able to think of options as quickly as some people. This might lead to panic and to the perception of a greater sense of danger. ....
...
I would make the additional point that although the (sic) this event might be considered insufficiently severe to cause PTSD in some individuals of a more robust psychological nature there would be a significant number of people in the community not suffering a pre-existing a (sic) mental illness who would suffer a similar stress reaction given the same event. The susceptibility to PTSD varies significantly and depends on past exposure to stress, coping mechanisms ad (sic) possibly genetic factors.
11. Although the anxiety symptoms may result from him being more susceptible as a result of his schizophrenia his current symptoms of stress which have been discussed in this report are not due to schizophrenia but due to a severe stress reaction as discussed.
12. I consider that Post-traumatic Stress Disorder has rendered Mr Edington totally and permanently disabled for the purposes of the definition under the terms of the policy. He is unable to a (sic) perform work in a job predominantly involving manual and walking duties i.e as a Field Assistant and this is primarily due to his intense fear (sic) being attacked by dogs and has nothing to do with his residual symptoms of schizophrenia. ...
I consider that the events of January 2002 gave rise to a stress condition notably PTSD which has affected Mr Edington's ability to work in his previous position...
...
Dr de Leacy also criticises the medical reports of Dr Olsen and Dr Reddan, but endorses comments of Dr Butler in his report.
14 The Tribunal noted that there had been considerable variation in the clinical history provided by the applicant to the reporting health practitioners, and that there was a dissent of opinion among the reporting psychologist and psychiatrists both to the diagnosis of the applicant's post-injury psychological condition (although all acknowledged his pre-existing paranoid schizophrenia) and the psychological cause of his total incapacity for work. In summary, the Tribunal noted that:
· Ms Jooste and Dr de Leacy had diagnosed PTSD attributable solely to the incident of 2 January 2002
· Dr Butler and Dr Reddan had diagnosed an anxiety disorder, and Dr Butler also diagnosed a phobia to dogs, both doctors rejecting the diagnosis of PTSD.
