HER HONOUR:

1 Mr Matthews (the worker) was in receipt of WorkCover payments for a back injury that had occurred in September 2004 (the Workplace Incident). When his weekly payments and medical expenses were terminated in 2018, he commenced proceedings in the Magistrates’ Court of Victoria. The Magistrate referred questions to a medical panel (the Panel) in accordance with the Workplace Injury Rehabilitation & Compensation Act 2013 (Vic) (WIRC Act). The opinion of the Panel had the effect of conclusively determining the proceeding adverse to the worker on the question of ongoing entitlements. The plaintiff seeks orders quashing the Panel’s certificate of opinion dated 24 February 2020 (Opinion) and remitting the referred medical questions to a differently constituted medical panel.
2 The Panel, constituted by Dr McRae, Mr O’Loughlin, Associate Professor Chalkiadis and Dr Grant, who are the second to fifth defendants, have taken no part in the proceeding in accordance with a Hardiman letter dated 30 March 2021.[1] The first defendant employer is the contradictor.
3 The claim form had identified the injury as occurring on 27 September 2004 when unloading and lifting computer monitors off the back of a truck. He had been working in this employment since February 2004. The injuries in the Magistrates’ Court pleadings were for injury to the thoracic and lumbar spine with a consequential pain syndrome and consequential psychiatric injury. The defence pleaded that the plaintiff has a current work capacity, and if he did not, then any incapacity does not result from, nor is materially contributed to, by the injury.
4 The worker had previous claims for back and other injuries from work incidents and car accidents. He also suffered an injury in a subsequent car accident on 24 December 2005 in which he suffered significant unrelated injuries included injury to his cervical spine.
5 It was in this context that the Panel provided its answers to the following questions:

Question 1: What is the nature of the Plaintiff’s medical condition, including any sequelae, relevant to the following alleged injuries:
  1. injury to the lumbar spine;
  2. injury to the thoracic spine;
  1. consequential pain syndrome;
  1. consequential psychological/psychiatric including anxiety and depression (“the said injuries”)?
Answer: The Panel is of the opinion Mr Matthews is suffering from chronic axial musculoskeletal pain in the setting of past thoracic crush fractures, multiple motor vehicle accidents, including a motor vehicle accident requiring hospitalisation after the alleged injuries, osteoporosis and previous workplace injuries causing age-related, constitutional degenerative thoracic spine changes. The Panel is of the further opinion that he suffered a now-resolved symptomatic exacerbation injury of his thoracic spine at the time of his alleged injuries, and he is now suffering no medical condition of his lumbar spine, thoracic spine or consequential pain syndrome relevant to the claimed injuries.
The Panel is also of the opinion that Mr Matthews has a mild chronic Adjustment Disorder arising secondary to chronic pain and physical restrictions attributable to his now resolved physical injuries, his relationship breakdown and his ongoing medical, non-injury-related diagnoses.
Question 2: What is the extent to which any physical or mental condition of the Plaintiff results from or is materially contributed to by any and if so which of the said injuries?
Answer: The Panel is of the opinion that Mr Matthews’ symptomatic exacerbation injury of his thoracic spine in the setting of past thoracic crush fractures, multiple motor vehicle accidents, osteoporosis and previous workplace injuries causing age related, constitutional degenerative thoracic spine changes, resulted from and was materially contributed to by his claimed injury, however no longer results from or is materially contributed to by the claimed injury.
The Panel is also of the opinion that Mr Matthews’ mild chronic Adjustment Disorder was and still is materially contributed to by his physical injuries (which have now resolved).
Question 3: As at the date of the Medical Panel’s examination of the Plaintiff, does the Plaintiff have:
  1. a current work capacity; or
  2. no current work capacity?
Answer: In the Panel’s opinion Mr Matthews has no present inability arising from an injury such that he is not able to return to his pre-injury employment.
Question 4: If the plaintiff has no current work capacity, is such incapacity likely to continue indefinitely?
Answer: Not applicable
Question 5: If applicable, whether the Plaintiff’s incapacity for work, if any:
  1. resulted from or was materially contributed to by;
  2. results from or is materially contributed to by –
  1. any, and if so, which of the said injuries?
Answer: Not applicable

6 There are nine grounds for review. In essence most address error in the Panel’s answer to Question 1 and the conclusion that the worker suffered a ‘now resolved symptomatic exacerbation injury of his thoracic spine’ in the Workplace Incident.[2] The first five grounds in various ways attack this conclusion on the basis that there was no evidence of pre-existing symptoms or signs of back pain and limitation prior to the incident and that the Panel failed to have regard to relevant material which demonstrated a lack of any signs or symptoms of back pain prior to the Workplace Incident.[3] The further three grounds attack the conclusion that the symptomatic exacerbation injury had resolved on the same bases of no evidence or a conclusion not open to the Panel or reliance on irrelevant material. The final ground addresses a failure to explain a path of reasoning to the conclusion reached.
7 For the reasons that follow, I have concluded that the Panel’s reasons did not disclose a path of reasoning so as to understand the conclusions that they reached as to the nature of the alleged injury and its cessation. This inadequacy makes it impossible to determine whether or not there was legal error in the considerations that the Panel was obliged to have regard to and whether or not there was some evidence upon which their conclusions were based.

Identifying the injury - Question 1

8 The Panel commenced its reasons by noting Mr Matthews to be a difficult historian with a complex medical history, which included multiple spinal injuries and other medical conditions. It noted that his answers were inconsistent or often provided unrelated information. In addition to Mr Matthews’ own answers, the Panel had access to voluminous medical material including medical records and reports from various treating practitioners and medico-legal examiners both before and after the Workplace Incident.
9 Allowing that the Panel found Mr Matthews to be a difficult historian, I will commence with a summary of the documentary material before the Panel as to the prior injuries, symptoms and restrictions. This fell into two categories: those reports that predated September 2004 and dealt with pre-existing injuries, and those since 2004 dealing with the pre-existing situation, the Workplace Incident and the subsequent motor vehicle accident. It is useful at this stage to focus on the material at and before September 2004.
10 The claim form had identified previous pain and disability in the area of his present injury and described this as ‘previous back injury long time ago’.[4] The initial medical certificate identified ‘strained upper thoracic T5-6 spine, mild strain to lumbar spine’. As to previous history it said, “past history of crush fractures T8/T9 probably unrelated to current problem”.[5] The medical certificate was provided by the Monash Emergency Department, the plaintiff having been driven there from work because of his symptoms.

The prior history of spinal injury

11 Before the Workplace Incident, the earliest documented episode of back pain is a Workers’ Compensation Claim in Queensland in 1981 when Mr Matthews was 20 years old. He suffered a low back strain lifting heavy bags of flour. There was some reference to sciatic pain into the legs. An orthopaedic registrar wrote that on review there were no neurological deficits and no abnormality on x-ray. The medical consensus was a ligamentous and muscular strain. A series of reports from the treating general practitioner at the time, Dr Allchin, document persistent pain continuing until his last report in October 1982. In that last report, he confirms the ongoing nature of symptoms since their commencement in August 1981 and that recent events were not a recurrence. This seems to be a reference to Mr Matthews’ recent attempt to start a business driving a tip truck, which he found was work he could not handle because the activity worsened his level symptoms.
12 In 1983, Mr Matthews attended Dr Allchin following a motor vehicle accident in which he was hit from behind in a stationary car. He was said to have a low back and neck strain. Nothing further was noted regarding this incident.
13 In 1984, Mr Clifford examined Mr Matthews for medico-legal purposes. He recorded a history of back pain commencing when lifting a jack in 1979 which led to a week off work with a second episode of injury lifting bags of flour, in 1981. He noted the time off work and the attempt at the tip truck business towards the end of 1982. Since that time, the worker was said to have had various forms of employment but was unemployed from 1983, and was currently volunteering at Yooralla and hoping to obtain paid work. He presently had some pain, worse with activity, for which he was taking no pain medication. He had near full range of movement and an x-ray at the time showed no abnormality. Mr Clifford thought he was fit for work in any field which did not require moderately heavy lifting. He attributed most of the problems to the 1981 injury. He opined that the injury did not relate to any pre-existing condition and will not worsen without further injury.
14 From the documents it appears that in May 1984 Mr Matthews commenced work with City of Moorabbin and on 21 May 1984 he suffered a work injury of a strained back while removing a cement saw from a trailer.
15 A letter from State Insurance Office refers to a workplace accident on 29 May 1985, where Mr Matthews suffered a ‘slipped and torn disc’ while stepping from his truck. The claim involved weekly payments for one week and total medical expenses of $150. An x-ray was taken as part of that claim. Dr Allchin also reported in relation to this injury describing it as substantially resolved by 6 June 1985.
16 Next there was a motor vehicle accident on 22 August 1985. The plaintiff was the driver when he was struck by a vehicle that turned right into his path of travel. The County Court Writ issued in relation to that accident claimed injury to the cervical and lumbar spine and compression fracture of T8 among other particularised injuries. His employment at the time was said to be as a council worker and particulars of special damage in the statement of claim modestly claimed that he was unable to work for one week following the collision and that he may have a diminution in capacity for particular employment activities.
17 In December 1985, Dr Allchin provided a medical report in relation to injuries sustained in this latest motor vehicle accident. X-rays at that time revealed a compression fracture of the 8th dorsal vertebra and evidence of Scheuermann’s disease but no injury in the lumbar or cervical spine. Within two days, neck pain had cleared and some mid-dorsal pain consistent with the compression fracture remained. Having described the various incidences of injury thus far, Dr Allchin stated in December 1985 that:

It would be thus reasonable to assume that these three episodes [1981, the March 1983 car accident and May 1985] would have left some residual disability which was aggravated in the accident on 21 August 1985. The injury to his dorsal spine and the compression fracture of his 8 dorsal vertebra was certainly caused by this accident and will be responsible for a degree of permanent disability.[6]

18 Mr Clifford examined Mr Matthews for a second time in May 1986. By that time the worker had improved. He remained working at a local council as a driver and was studying at RMIT. He had some thoracic pain and occasional lumbar pain that did not worry him significantly. Mr Clifford noted the 1985 x-ray showing thoracic region Scheuermann’s disease and no lumbar abnormality. The previous problem was described as ‘all but settled’.[7] He thought the Scheuermann’s was the cause of the thoracic pain rather than the earlier work injury or car accident.
19 Mr Critchley also examined him in 1986 in relation to the 1985 car accident. He opined Mr Matthews had suffered a soft tissue injury to his neck and back and was making a satisfactory recovery, prognosticating for a full recovery.
20 In August 1986 he had been medically examined in relation to the 1985 motor vehicle accident by Mr Wale, a surgeon. He gave a history of the 1983 motor accident which led to no time off work or medical treatment. He was diagnosed with a flexion and extension injury in the 1985 car accident which had resolved ‘almost completely’.[8] Further improvement was expected with him becoming pain free over time.
21 A 1986 Work Injury Claim form noted a strained muscle in the side of back suffered by the plaintiff when catching a machine falling off a trailer on 7 November 1986 while working for the local Council.
22 When seeing the plaintiff again in August 1988, Mr Wale obtained a history that he had been working between March and May 1988 as a landscape gardener, which involved a lot of heavy lifting. He observed a good recovery from the 1985 motor vehicle accident and return to an occupation with a large physical input. However, he also observed the complication of a further recent motor vehicle accident which had left the plaintiff’s right leg in a cast.
23 That motor vehicle accident had occurred on 23 May 1988 (the 1988 accident) when the plaintiff was driving home from his work with the Council. His occupation at that time was listed as bluestone worker. He fractured his left clavicle, right ankle, damaged his right knee, left ankle, right shoulder and lost part of an ear. There was initially no mention of back or neck pain in the documentation relating to this accident.[9] He received weekly payments until they were terminated in January 1992.
24 In disputing that termination, a medical report by Dr Fredman[10] (from the same clinic as Dr Allchin) was prepared. He noted that Mr Matthews had been a patient of that clinic since at least 1966 (at which time he would have been five years old). That report made clear that Mr Matthews had been working for Moorabbin Council between 1984 until about 1987 and thereafter as a bluestone mason initially part-time from August 1987 and then full-time from March 1988 until the 1988 accident. Prior to that work, he also had a stint as a self-employed mechanic. He detailed psychiatric problems during this time which had not precluded him from work. It confirmed an ongoing incapacity for work by reason of the injuries related to the 1988 accident. By 1992, Dr Fredman included a lumbar spine and sacro-iliac joint strain in the complaints since the 1988 accident. It confirmed he was working and not needing attention for physical disability in the years prior to May 1988.[11]
25 In its determination of the dispute in April 1992, the WorkCare Appeals Board (the WAB) affirmed the decision to terminate weekly payments concluding that the physical injuries no longer precluded him from carrying out his pre-injury duties and that his psychiatric condition would preclude him from returning to employment but was unrelated to the 1988 accident.
26 There was a discharge summary from a psychiatric admission in 1989. He had significant psychiatric and criminal issues at that time. It was recorded that he trained as a motor mechanic and enjoyed that work until the car accident (presumably a reference to the 1988 accident) which he could no longer do because of leg pain.
27 On 3 April 1999, an x-ray report, addressed to Dr Fredman, was conducted of the whole spine and abdomen. The only spinal abnormalities noted were the longstanding compression fractures at T8 and T9. There was no indication as to the reason for the investigation.
28 There are no other contemporaneous medical documentation regarding pre-accident symptoms.
29 The Panel obtained a history from Mr Matthews that from the late 1980s he moved into the computing and information technology field.[12] It was clear that this followed retraining during rehabilitation from the 1988 accident.

Subsequent injury

30 Subsequent to the Workplace Incident, the plaintiff was involved in a further motor vehicle accident on 24 December 2005 (2005 accident). He was a passenger in a stationary vehicle that was rear ended. His Transport Accident Commission claim form referenced an existing thoracic spine injury for which he was receiving physiotherapy, hydrotherapy, he was seeing both a general practitioner and specialists and was taking oxycodone, diazepan, mobic and nexium.
31 The injuries received in this accident were identified by the Alfred hospital as neck injury, closed head injury and headache.

The Panel’s Reasons

32 In the reasons for its Opinion, the Panel set out a section headed ‘History Provided by Mr Matthews’, which dealt with what the Panel was told about the worker’s employment with the first defendant and the circumstances of the Workplace Incident. It references both the Workplace Incident and a history of a “twinge” felt some days earlier when moving heavy furniture. It otherwise does not reference symptoms of back pain while working in computing and information technology with the first defendant or otherwise.
33 It then set out details of other injuries under a heading ‘Past Spinal Injury History’. It appears to be drawn from documentation and there is nothing to indicate that any part of that history was obtained from Mr Matthews during his attendance at the Panel.
34 In the ‘Past Spinal Injury History’ section the Panel identified the 1979 and 1981 injuries. The reasons then stated:

He was involved in several motor vehicle and work related accidents with various spinal injuries between about 1983 and 2005.[13]

35 The Panel went on to list the 1983 and 1985 car accidents and the slip from the truck in May 1985, a work incident in June 1986[14] and the November 1986 falling equipment claim. The Panel then continued:

He had a further motor vehicle accident about 23 May 1988, which resulted in a fractured left clavicle and right ankle and right tibial spine. He was hospitalised for about five days after a motor vehicle accident about 24 December 2005 when he was a front seat passenger in a vehicle hit from behind, and which included head trauma without loss of consciousness. After these past back pain episodes, he had ceased all analgesic medications, and was taking none prior to the incident.[15]

36 Although the 1988 accident did not involve any discrete injury to the spine, the Panel made reference to Dr Fredman’s recorded complaint of lumbar spine strain and the worker’s history as given to the WAB, and appears to have included time after that accident as a period producing lower back pain. The reason for including the 2005 accident immediately prior to summarising the situation prior to the incident is not apparent.
37 From this material, evidence of back pain between 1979 and 1986 included both times of persisting pain and other occasions of pain that settled quickly. The Panel made specific reference to the WAB’s history that he ‘continued to suffer with lower back pain down both legs into his knees and ankles. When his back pain is severe he has to lie down to reduce that pain’ and the reference to Dr Fredman’s findings of tenderness of the lumbar spine and both sacroiliac joints, and sciatica in both legs from the S1 nerve root.[16] The Panel had no other material before it as to back pain or other signs or symptoms from 1992 until 2004, save for the normal x-ray report of 1999.
38 The Panel then set out the current symptoms, and medication use, again noting no use of analgesia ‘immediately’ prior to the incident. It set out its findings from both the physical and psychiatric examinations and gave a recitation of all the radiological reports both before and after September 2004.
39 The Panel then set out its assessment. It considered that the examination demonstrated significant non-organic illness behaviour and behavioural features of protective pain behaviour. As to the injury sustained in the work incident it concluded:

... that Mr Matthews suffered a symptomatic exacerbation of chronic, post-traumatic pain secondary to multiple previous back injuries sustained in motor vehicle and work-related accidents that has since (after more than 14 years) resolved. Following a more recent motor vehicle accident in 2005, after the incident, Mr Matthews’ pain symptoms have increased as supported by the report of his treating psychologist and his increased analgesic requirements. The Panel considers that his underlying constitutional condition is now causing his current symptoms.[17]

40 As to the present medical condition the Panel concluded that:

... he is now suffering from chronic axial musculoskeletal pain as a result of past thoracic crush fractures, multiple motor vehicle accidents, including a motor vehicle accident requiring hospitalisation after the incident, and osteoporosis. The Panel further concluded that Mr Matthews is suffering no medical condition of his lumbar spine, thoracic spine or consequential pain syndrome relevant to the claimed injuries.[18]

41 The worker submitted that the history of spinal injury as outlined above provided no evidence from which the Panel could conclude that what occurred in September 2004 was a ‘symptomatic exacerbation of chronic, post traumatic pain’.[19] He further submitted that the history relevantly demonstrated an absence of signs and symptoms of thoracic or lumbar back pain for a substantial period of time prior to 2004 and this was disregarded.
42 The first defendant submitted that the characterisation of the injury as an exacerbation injury did not assume any particular pre-existing level of signs or symptoms. Rather by its description as a ‘symptomatic exacerbation injury’ in answer to Question 1, the Panel referred to the type of injury and not to an exacerbation of symptoms.

Analysis

43 In oral argument the defendant took me to the very clear statements of Kitto J in Federal Broom Co Pty Ltd v Semlitch[20] as to the nature of an exacerbation injury. Construing the definition of injury, which included injury by way of aggravation, acceleration, exacerbation or deterioration, the Court said each of the four qualifying words were not synonymous with each other. As applied to a psychiatric disease, Kitto J said of an exacerbation injury:

It is properly used to refer to effects which the disease produces in the victim rather than to the advance of the disease itself to a more serious stage of its development.[21]

44 Kitto J approved the trial judge’s wording:

There is an exacerbation of a disease where the experience of the disease by the patient is increased or intensified by an increase or intensifying of symptoms.[22]

45 The word directs attention on the experience of the disease rather than the underlying mechanism or progress. In Semlitch, the exacerbation was evidenced by the onset of a new delusion which caused an incapacity for work. Kitto J used the illustration of salt rubbed into a wound, making the wound sting but not altering the wound, as an example of an exacerbation injury.
46 The analysis is helpful. Considering the application of salt in this case to be the occurrence of the Workplace Incident, the question can then be posed – what symptoms did the Panel consider were intensified or increased, or what new symptom was introduced, by the Workplace Incident? By reference to its reasons, the Panel answered this by identifying the underlying wound as ’chronic, post traumatic pain secondary to multiple previous back injuries’ sustained in identified accidents. In context, this cannot logically be a new symptom of pain but an intensification of previous pain, which was already considered by the Panel to be chronic in nature.
47 This is, in my view, borne out by the reasons in a number of ways. First, a fair reading of the reasons as a whole describes a continuum from the time of the initial work injuries. The Panel commenced its summary of the past episodes of injury as quoted above at 34 as a period between 1983 and 2005. It concludes with the statement quoted above at 35 that after all these he had ceased all analgesic medication and was taking none prior to the Workplace Incident. Inexplicably, the Panel seems to have included the 2005 accident in these episodes.
48 Second, the Panel qualified the period of no use of analgesia for back pain to a time ‘Immediately prior to the incident’, which at least inferentially suggests it acted on the understanding that between 1992 and 2004 analgesic use for back pain continued. The documentary evidence does not reveal a basis for such a finding and the reasons do not disclose such a history having been obtained from the worker.
49 Third, and perhaps critically, the Panel disagreed with the opinion of the general practitioner who had been treating Mr Matthews since the late 1990’s on the question of the onset of symptoms. Dr Christiansen took over treatment of Mr Matthews since the retirement of Dr Fredman in the mid-90s.[23] In January 2007, Dr Christiansen wrote to QBE workers compensation in respect of the 2004 WorkCover claim in these terms:

Mr Matthews has asked that I confirm his serious injury to you. He is severely limited in most physical activities by a permanent painful kyphoscoliosis. This has been stable for some twelve (12) months after a progressive worsening since his injury.
As you are aware he has compression fractures of four (4) thoracic vertebrae. Every treatment modality suggested by myself and his specialists has been well complied with but of no use.
He is not fit for gainful employment for the foreseeable future.[24]

50 Dr Christiansen said Mr Matthews was unable to work again, and that “this was the case after his thoracic spine injury – he is kyphotic and stiff and requires constant narcotics for pain”.[25] The Panel made particular reference to this report.
51 The Panel took issue with Dr Christiansen’s opinion and did not accept his attribution of thoracic pain and stiffness to the 2004 Workplace Incident. It considered that the kyphoscoliosis and compression fractures pre-dated the Workplace Incident. Both may well have pre-dated the incident. However it went on to say:

The Panel noted that Dr Christiansen attributes Mr Matthews’ symptoms to the incident, but the Panel notes the pre-existing symptoms and signs from prior to the incident.[26]

52 The Panel then recorded a number of reports written by Dr Christiansen all documenting chronic and intractable pain, [27] stooped posture and need for narcotic medication commencing from the incident in 2004, and reporting [Mr Matthews’] 1980s motor vehicle accident and associated T8 vertebral crush fracture, and emphasising his thoracic spine pain.
53 The Panel came to a view about symptoms prior to September 2004 contrary to that consistently expressed by Dr Christiansen since 2005.[28] It was entitled to reach that conclusion, but at the very least it was obliged to make clear a path of reasoning as to why the Panel reached a different conclusion as to symptom onset. A bald statement noting ‘pre-existing symptoms and signs from prior to the incident’,[29] as an explanation for disagreeing with Dr Christiansen’s observation without qualification is not a path of reasoning. Neither the documentation provided nor the history obtained from the worker demonstrated the continuation of chronic symptoms and signs persisting until shortly before or at the time of Workplace Incident. The Panel was not simply disagreeing with Dr Christiansen’s opinion as to causation, it was also disagreeing with Dr Christiansen’s report that as a matter of fact symptom onset on presentation to him dated from September 2004.
54 Fourthly and similarly, the Panel expressed its disagreement with Dr Gassin’s assessment in his 2019 medico-legal report. Dr Gassin reported that the worker had a history of early 1980s back pain, and made reference to the 1988 and 2005 car accidents with the injuries as claimed. He concluded that Mr Matthews was known to have pre-existing changes in his thoracic spine and felt it probable that the Workplace Incident aggravated these conditions. The Panel said Dr Gassin was told ‘Mr Matthews relate[s] the onset of his thoracic back pain to the performance of a specific duty at work on 27 September 2004....’.[30] The Panel said that it is:

... satisfied there is sufficient evidence that this premise is incorrect, so it came to a different conclusion to Dr Gassin.[31]

55 Nowhere do the reasons identify what factors amounted to the sufficient evidence upon which the Panel was so satisfied.
56 Indeed the Panel continued to then repeat the form of words when noting and disagreeing with the opinion of Dr Slesenger. It said:

The Panel noted the opinion of Dr Slesenger, Specialist Occupational Physician, dated 18 March 2019 in which he stated “Mr Matthews advised that he was injured during the course of his employment”. The past history he obtained included an episode of lower back pain some 30 years ago, treated with a steroid injection, resolving completely without recurrence until the injury under consideration”. The Panel is satisfied there is sufficient evidence that this premise is incorrect, so it came to a different conclusion to Dr Slesenger.[32]

57 Clearly that history as quoted is incomplete and inaccurate although Dr Slesenger also had, and made reference to, x-rays predating 2004 that demonstrated crush fractures in the thoracic spine. It is unclear whether the Panel was disagreeing with the stated premise that an injury occurred at work in 2004 or an unstated premise that Dr Slesenger attributed the crush fractures to be related to the 2004 injury. Either way, nowhere is the sufficient evidence identified from which the Panel reasoned to its own different conclusion.
58 Subsequent medico-legal opinions were many. The completeness or accuracy of the history they recorded was variable. The Panel is not required to explain its disagreement with other opinions but it is obliged to set out the basis for arriving at its own conclusions. It is entitled to and indeed required to act upon its own expertise and clinical judgment. That includes its own findings of fact as to matters of history. As to matters of history, it is obliged to set out those relevant findings so as to understand the basis for its own conclusion.
59 True it is that the reasons are to be read as a whole, and not scrutinised with zealotry to discern inadequate reasons.[33] The reasons inform the manner in which the questions have been answered by the Panel and need to be sufficient to disclose whether the Opinion does or does not involve any error of law.[34] They are required only to demonstrate the path of reasoning employed to arrive at the Opinion that the Panel actually formed.[35]
60 I do not accept the first defendant’s submission that the Panel concluded what had been sustained was an exacerbation of the thoracic spine condition which had associated symptoms and not that there had been an exacerbation of symptoms. To the extent that there is a discrepancy between the language of the Panel’s answer, ‘an exacerbation injury’, and the Panel’s reasons, ‘a symptomatic exacerbation of ...pain’, it was said to be explicable as merely loose language. The defendant submitted that properly understood, the phrasing in the reasons was consistent with the answer given and did not assume a particular level of symptoms prior to the Workplace Incident. In my view the Panel’s rejection of Dr Christiansen’s observation makes this an unlikely interpretation.
61 The distinction in wording between the answer in the Opinion and the reasons is a distinction without a difference. To the extent that the role of the reasons is to explain the path of reasoning to an ultimate conclusion they should be read consistently. The reasons as a whole make clear that the Panel did proceed on the basis that the worker had signs and symptoms persisting up until shortly (or perhaps immediately) before the incident, which included a degree of persisting pain.
62 If the various factors identified, both traumatic and non-traumatic, gave rise to a conclusion that the worker suffered a level of signs and symptoms that persisted beyond the documented symptoms to 1992, and remained present thereafter until 2004, then the Panel is obliged to explain how it came to that conclusion. The history of the Workplace Incident is replete with descriptions in quotation marks of phrases presumably attributed to the plaintiff’s own words but the history of other incidents is written almost exclusively by reference to the documentation, and so does not deal in a contemporaneous way with circumstances between 1992 and 2004. The Panel did not say that it asked the worker about whether there were symptoms in his spine persisting at any time after 1992 or about the quality of any persisting symptoms. It may not be bound to accept the answer but in my view it was appropriate that it make that relevant inquiry for the purpose of arriving at its Opinion. Nothing in the reasons indicates that it turned its mind to that substantial period of time or why it disagreed with Dr Christiansen’s observations.
63 In Chang v Neill & Ors,[36] the Court of Appeal discussed a medical panel’s peculiar role to provide an informed professional opinion on the medical questions before it. It did so by reference to the statutory scheme and the oft quoted observations in Wingfoot Australia Partners Pty Ltd v Kocak.[37] The Court said:

... a medical panel is required to provide an informed professional opinion on the medical questions referred to it. Where, in a given case, a medical panel considers that it is not able to provide such an opinion because of material deficiencies in the information available to it, it cannot ignore those deficiencies and proceed to reach an opinion which is not an informed professional opinion. Rather, in that situation, it is empowered by s 312(1)(a) of the Act to seek such further information as it requires to provide an informed professional opinion.[38]

and

As a matter of common sense, where a medical panel requires a worker to attend an examination for the purpose of obtaining information to assist it to answer the medical questions referred to it, the panel must direct and guide the discussion with the worker to ensure that the information that the panel considers relevant is elicited from the worker. In such a case, the panel could not simply leave it to the worker to determine what information should be provided to the panel. Rather the panel must ask such questions as it considers necessary to enable it to provide an informed professional opinion on the medical questions.[39]

64 The Panel needed to identify whether and what level of signs and symptoms continued in the time leading up the work injury for two reasons. First, using the analogy in Semlitch, it is for the purpose of identifying the wound to which the salt is applied. It may be that the underlying condition was symptomatic (including that it was painful) or was asymptomatic but restrictive in order to avoid the onset of further pain, or was asymptomatic and not restrictive. Semlitch makes clear an exacerbation injury may occur in all situations. The presence or the extent of symptoms will necessarily inform the nature of the exacerbation. It is also important as part of the reasoning for whether or not that exacerbation injury has resolved, which lay at the heart of Question 2.

Resolution of the exacerbation injury

65 The way in which the 2005 accident was included in the chronology of prior events makes some of the reasoning confusing although there can be no doubt the Panel appreciated that it was a subsequent event. Whatever the 2005 accident caused, it could have had no bearing on the worker’s condition at the time of the Workplace Incident. The relevance of the 2005 accident was twofold. One was that it fixed, by reference to the claim lodged in December 2005, some contemporaneous evidence about the persisting treatment for thoracic pain including medication at that time. This obviously was continuing at least from September 2004 but it could say nothing as to the state of affairs prior to that date. Second, although there was no frank injury to the thoracic spine, only to the cervical spine, there was from that time a complaint of increased thoracic pain. The Panel accepted this aspect of the history. The Panel clearly thought that worsening thoracic pain was relevant to its conclusion that the earlier exacerbation injury has resolved. The reason for that relevance was at best opaque.
66 The confusion that arises from including the 2005 accident as part of a narrative of prior events can be seen by the Panel’s treatment of events before and after this accident. When describing the course of treatment following the 2004 incident the Panel noted:

Mr Matthews “could not get out of bed for two or three days”, as he could not stand up due to shooting pain from his mid-thoracic area that pulsed down his spine, mainly down his right leg to the lateral toes. He consulted his general practitioner who referred him for physiotherapy, hydrotherapy and to an orthopaedic surgeon, who recommended conservative treatment. He was referred to a pain medicine specialist. He had a motor vehicle accident about 24 December 2005, which included head trauma, and required hospitalisation. He had ongoing headaches and neck and upper extremity pain symptoms. He was referred to a psychologist about the middle of 2005, and commenced antidepressant medication from about the middle of 2005. His shooting pains increased with frequency over time. He had physiotherapy, hydrotherapy and massage which made his neck and thoracic pain symptoms worse. He has not worked or tried to work since the incident.[40]

67 It is a paragraph that is chronologically erratic and thereby unclear whether the Panel appreciated that the psychological referral and anti-depressant medication were wholly related to the Workplace Incident injuries and not the 2005 accident.[41] To say that treatment made thoracic and neck pain worse presumably relates only to treatment after December 2005 as there was no history of neck pain predating the 2005 accident. Nor was there any suggestion that treatment prior to December 2005 was making symptoms of thoracic or lumbar pain worse. The Panel made no effort to identify or distinguish a level of symptoms between September 2004 and 23 December 2005, or any change brought about by the intervention of the subsequent car accident. Accepting that the thoracic pain worsened from the time of the subsequent car accident, how did the Panel reach the conclusion that the exacerbation from the Workplace Incident had resolved?
68 The Panel described present axial pain localised to the region of the past vertebral crush fractures and the cervical spine (unrelated to the Workplace Incident). It noted the advancement of degenerative changes since the incident despite not working afterwards and having a substantial motor vehicle accident subsequently.[42] The only explanation for the resolution of injury in the context of continuing symptoms was that:

...it has since (after 14 years) resolved.[43]

69 This conclusion was supported by two opinions as to what, in the Panel’s own view, was now responsible for the continuing symptoms. The Panel concluded that the worker’s current symptoms were now caused by his underlying constitutional condition as set out above at 39. By that conclusion all previous traumas dating back to 1981 including 2004 and any increase following the subsequent car accident, appear to no longer play any role in his symptoms. However, the Panel also concluded, as set out at 40 above, that his present chronic pain was as a result of all of those past work accidents and car accidents both pre and postdating the Workplace Incident and osteoporosis (diagnosed in 2006), but no longer from the Workplace Incident. A path of reasoning was called for that demonstrated how these two seemingly contradictory conclusions as to the causation of his present condition had been arrived at in order to understand the Panel’s answer to Question 2 and its reason for concluding that there had been resolution of symptoms relating to one prior incident. That reasoning in turn would be relevantly informed by the findings of the Panel as to the underlying injury that had been exacerbated.
70 The ground of inadequacy of reasons has been made out in relation to the answers to Questions 1 and 2. The Panel chose to characterise the injury it identified as an exacerbation injury and identified that which was exacerbated as pain that was both chronic in nature and post traumatic in origin. It did so, in answer to Question 1, by referring compendiously to the context or setting of past crush fractures, multiple motor vehicle accidents (some of which did and others did not involve thoracic or lumbar spine injury), previous work injuries and a subsequent motor vehicle injury, as well as osteoporosis. Some or all of these matters are described as causing age-related, constitutional degenerative thoracic spine changes. This provides little more than a list of factors that require evaluation in order to arrive at an appropriate answer to the question. The reasons could have and should, but did not in my view, provide a real explanation of the way that any constitutional conditions and the consequences resulting from various events up until 1988 were impacted upon by the Workplace Incident. The conclusion, in the face of ongoing pain after the exacerbation has ceased, and in the circumstances of this complex presentation, required greater explanation than simply that the passage of time has led to the conclusion as to the causes of his present symptoms.
71 In essence, the path of reasoning ought to have addressed three fundamental stepping stones. One, the nature of the underlying condition as at September 2004; two, a description of the new or intensified features that demonstrated the exacerbation injury; and three, the mechanism by which the passage of time and the significance of other causal factors alone or in combination, has led to any resolution of the exacerbation injury.
72 These conclusions mean that it is not strictly necessary to decide the no evidence grounds or whether relevant material was overlooked. A finding of fact made where there is no probative evidence to support the finding amounts to a jurisdictional error.[44] To say that a finding is not reasonably open amounts to the same thing.[45] This is to be distinguished from a wrong finding of fact, which does not give rise to any legal error. Where a Tribunal arrives at its own expert opinion as a medical panel is required to do, it may be more difficult to demonstrate that a finding was not open to it.[46] Indeed the inadequacy of reasons makes it difficult to identify whether or not the Panel did proceed in error in these ways.
73 Having said that, there was clearly evidence that at times prior to 2004 the worker had suffered thoracic and lumbar spine pain. Although expressly referencing ‘pre-existing signs and symptoms’ which undoubtedly existed at some point in time, the inadequacy of reasons makes it difficult to determine the question of whether a legal error of fact-finding has occurred. Equally, to the extent the Panel was said to have not taken into account a relevant consideration (the state of the plaintiff’s thoracic and lumbar spine after 1992 until 2004), the reasons of the Panel premise signs and symptoms being present at some stage prior. Without explanation of how that conclusion is arrived at or how that premise affects the continuity or resolution of the exacerbation injury, the considerations that it did have regard to could not be identified.
74 Finally, and for completeness, the plaintiff put forward grounds of review based upon a misapplication of the principles in Walsh v Department of Human Services.[47] This was to meet an attack that the Panel may be thought to have taken the view that there were multiple causes for the worker’s present condition and it thereby disregarded the Workplace Incident. Walsh is a case dealing with incapacity rather than identification or causation of injury. The Panel here did determine there was an injury that resulted from employment. The real question was how it dealt with the identification and subsistence of that injury in the factual matrix of events. It is not necessary to consider the principles set out in Walsh as to causation of incapacity.
75 I will hear from the parties as to the appropriate form of orders.
