REVIEW PANEL ASSESSMENT OF DEGREE OF PERMANENT IMPAIRMENT

Certificate issued under s 7.26(7) of the Motor Accident Injuries Act 2017 (the Act)

1. The Review Panel revokes the certificate of Medical Assessor Christopher Canaris dated 21 February 2024 and issues a new certificate determining that:

(a) the following injury caused by the motor accident give rise to a permanent impairment of 15% and IS GREATER THAN 10%:

• major depressive disorder - moderate severity.

1. On 12 October 2018, whilst driving along South Terrace at Bankstown with a green light, a vehicle approached from the left to turn right into North Terrace, going west. The driver of that vehicle ran a red light and struck the claimant's vehicle on the left side at speed. The impact caused the claimant's vehicle to spin 180°. It was facing in the opposite direction after it came to rest. The claimant's three sons were passengers in the vehicle. An ambulance and tow truck were called. The vehicle being driven by the claimant was her husband's work vehicle. It was not drivable and subsequently was written off by her husband's insurer.
2. The claimant was involved in a previous motor accident in February 2018 when she and her children were passengers in a vehicle being driven by her husband onto the F1 Freeway at Figtree. They were travelling about 100 km/h as they entered the Freeway. The at-fault driver was travelling behind in the same lane at approximately 140 km/h. That vehicle clipped the back right of the vehicle in which the claimant was travelling, causing it to slide to the left and hit a metal crash barrier. The car in which the claimant's family was travelling span out of control and came to rest in the middle traffic island. The insured vehicle flipped onto its side. Ambulance, fire brigade and police officers attended.
3. Allianz (the insurer) indemnifies the owner and/or the driver of the at-fault vehicle for liability to pay to the claimant any damages under the Motor Accident Injuries Act 2017 (the Act). The insurer declined liability for payment of statutory benefits beyond twenty-six (26) weeks on the basis that all of the claimant's accident-related injuries relevantly are threshold injuries for the purposes of the Act. The insurer also declined to concede that the 10% whole person impairment (WPI) threshold is exceeded.

1. As there is a dispute between the parties about the degree of permanent impairment under Schedule 2, cl 2(a) of the Act, the claimant was referred to Medical Assessor Christopher Canaris for assessment. Medical Assessor Canaris certified on 21 February 2024 as follows:

The following injuries caused by the motor accident give rise to a permanent impairment of 9% and IS NOT GREATER THAN 10%:

Medical Assessor Canaris found 7% on the psychiatric impairment rating scale (PIRS) to which he added 2% to adjust for treatment effects. Medical Assessor Canaris stated that, while there is evidence of self-limiting symptoms of anxiety and depression in the past, these appear to have resolved completely prior to the subject accident. There is consequently no apportionment.

1. Medical Assessor Garvey certified on 25 November 2018 as follows:

C4/C5 and C5/C6 mild disc bulging without annular tear or disc protrusion is a minor injury. There is no evidence of radiculopathy on physical examination, so it is considered a minor injury under the definition

L4/L5 and L5/S1 early disc bulging without focal disc protrusion or annual tear is a soft tissue injury. There is no evidence of radiculopathy on physical examination. This is a minor injury under the definition.

Right shoulder - subacromial/sub-deltoid bursitis is a soft tissue injury of synovial membrane and is a minor injury.

Left shoulder - subacromial/sub-deltoid bursitis, Biceps tenosynovitis are soft tissue injuries of synovial membranes and are considered minor injury under the definition

are MINOR INJURIES for the purposes of the Act.

1. Medical Assessor Thomas Newlyn certified on 18 March 2019 as follows:

is not a MINOR INJURY for the purposes of the Act.

The Panel assumes there was no application for a review of that certificate.

1. The claimant sought a review of Medical Assessor Canaris' certificate, on the grounds that the medical assessment was incorrect in a material respect, under s 7.26 of the Act. The claimant relied on the particulars set out in the application and supporting documentation. The claimant brought the application within the time prescribed by s 7.26(10)(as) of the Act and cl 34 of Procedural Direction PIC 7 (28 days).
2. The claimant submits that Medical Assessor Canaris' certificate is incorrect in a material respect for his failure to provide adequate reasons why he disagrees with the claimant's IME Dr George, that the claimant suffers from persistent depressive disorder, for which Dr George assessed 15% WPI. The claimant submits that the reasons of the Medical Assessor are unclear and vague.
3. It is further submitted by the claimant that Medical Assessor Canaris failed to have proper regard to the evidence of impairment and erred in respect to the determination of WPI. The claimant particularises objections to each of the assessments made by Medical Assessor Canaris under the categories of self-care and personal hygiene, social and recreational activities, as well as adaptation under the PIRS. In relation to adaptation, the claimant submits that Medical Assessor Canaris failed to consider the role of the claimant in her husband's business and her adaptation.
4. The claimant' application for review was opposed by the insurer on various grounds. As those submissions were no accepted by the President's delegate, it is not necessary to state them in detail. Briefly, they can be summarised as follows:

(a) The insurer notes that Medical Assessor Canaris' certificate is wholly consistent with the earlier Certificate of Medical Assessor Thomas Newlyn who also diagnosed post-traumatic stress disorder only. The insurer says the two certificates confirm that the claimant's injuries meet the criteria of post-traumatic stress disorder and that no review application was lodged in relation to Medical Assessor Newlyn's certificate.

(b) The insurer submits the claimant's assertion that the Medical Assessor failed to properly consider the report of Dr Graham George is incorrect and appears to be the primary basis for the review application. Particulars are given of the consideration that Medical Assessor Canaris gave to the report of Dr George and his suggested diagnosis of persistent depressive disorder (Dysthymia).

(c) The insurer submits that it is not a proper ground for review that the claimant's opinion on the PIRS class ratings is different from those of the Medical Assessor who took an extensive history and whose reasons disclose his actual path of reasoning.

(d) The insurer notes that Medical Assessor Newlyn and Medical Assessor Canaris came to the same conclusion in finding that the claimant had only sustained post-traumatic stress disorder and that a review would result in the same outcome.

1. The Panel notes that the insurer's submissions do not respond to the claimant's submissions regarding the Medical Assessors' findings under the specified PIRS categories, nor his WPI assessment, to the extent that the claimant puts that assessment in issue.
2. President's delegate Rachel Britliff issued a Determination of an Application for Review of a Medical Assessment on 28 June 2024 which stated the satisfaction of the President's delegate that there is reasonable cause to suspect that Medical Assessor Canaris' assessment was incorrect in a material respect. The basis of that decision was stated as follows:

(a) Medical Assessor Canaris issued a certificate for the second (October) accident which was the same in every respect as the certificate for the first (February) accident except for the date of accident in the certificate header.

(b) He noted in the certificate that there were no prior accidents. He was aware this was not the case because he assessed the February accident at the same time he assessed the October accident.

(c) Clause 6.31 of the Motor Accident Guidelines v9.2 (Guidelines) states:

"The evaluation of the permanent impairment may be complicated by the presence of an impairment in the same region that existed before the relevant motor accident. If there is objective evidence of a pre-existing symptomatic permanent impairment in the same region at the time of the accident, then its value must be calculated and subtracted from the current WPI value. If there is no objective evidence of the pre-existing symptomatic permanent impairment, then its possible presence should be ignored."

(d) Medical Assessor Canaris found there was 9% WPI arising from the psychiatric injury that the claimant sustained in the February accident.

(e) I am satisfied that there is reasonable cause to suspect that Medical Assessor Canaris did not correctly apply cl 6.31 of the Guidelines. I am satisfied that there is reasonable cause to suspect that the medical assessment was incorrect in a material respect.

1. Accordingly, the claimant's review application was accepted. The Panel is to reassess the claimant's psychiatric condition and injury. Pursuant to cl 128(1) of the Personal Injury Commission Rules 2021 (PIC Rules), the Panel is to conduct and determine the proceedings, in accordance with procedures determined by the Panel.
2. The Panel notes that, in assessing WPI arising from the subject (second) accident, it is to have regard to the Oakley principles, as explained in Slade v Insurance Australia Limited t/as NRMA [2020] NSWSC 1031 per Wright J, unless the parties otherwise agree, noting that the same insurer is on risk for both accidents. The Panel also notes that it is to apply s 6.31 of the Guidelines, in evaluating pre-existing impairment arising from the February 2018 accident, noting that the same insurer is on risk for both accidents.

1. A medical assessment matter is determined in accordance with Division 7.5 of the Act. The matter is determined at first instance by a Medical Assessor pursuant to and, on review, by a Review Panel consisting of two Medical Assessors and a Member assigned to the Motor Accidents Division of the Personal Injury Commission (Commission).
2. Part 5 of the Personal Injury Commission Act 2020 (the PIC Act) enables the Commission to make rules with respect to the practice and procedure before the Commission, including proceedings before a Panel, reviewing a decision of a Medical Assessor.[1]
3. Rules 127 to 130 of the Personal Injury Commission Rules 2021 (the PIC Rules) are made pursuant to Part 5 of the PIC Act. A Review Panel determines how it conducts and determines the proceedings and may determine the proceedings solely based on the written Application.[2]
4. The review of the medical assessment is by way of new assessment of all the matters with which the medical assessment is concerned.[3]
5. All members of the Review Panel had no previous involvement with the claimant or with this matter.

1. Causation of injury is addressed in the Guidelines as follows:

"6.5 An assessment of the degree of permanent impairment is a medical assessment matter under cl 2(a) of Schedule 2 of the Act. The assessment must determine the degree of permanent impairment of the injured person as a result of the injury caused by the motor accident. A determination as to whether the injured person's impairment is related to the accident in question is therefore implied in all such assessments. Medical Assessors must be aware of the relevant provisions of the AMA 4 Guides, as well as the common law principles that would be applied by a court (or the Personal Injury Commission) in considering such issues.

6.6 Causation is defined in the Glossary at page 316 of the AMA 4 Guides as follows:

Causation means that a physical, chemical or biological factor contributed to the occurrence of a medical condition. To decide that a factor alleged to have caused or contributed to the occurrence or worsening of a medical condition has, in fact, done so, it is necessary to verify both of the following:

1. The alleged factor could have caused or contributed to worsening of the impairment, which is a medical determination.
2. The alleged factor did cause or contributed to the worsening of the impairment, which is a non-medical determination.

This, therefore, involves a medical decision and non-medical informed judgment.

6.7 There is no simple common test of causation that is applicable to all cases, but the accepted approach involves determining whether the injury (and the associated impairment) was caused or materially contributed to by the motor accident. The motor accident does not have to be a sole cause as long as it is a contributing cause, which is more than negligible. Considering the question 'Would this injury (or impairment) have occurred if not for the accident?' may be useful in some cases, although this is not a definitive test and may be inapplicable in circumstances where there are multiple contributing causes."

1. See Briggs v IAG Limited t/as NRMA Limited.[4] See also Insurance Australia Limited t/as NRMA Insurance v Trkulja [2023] NSWSC 956,[5] wherein his Honour Justice Wright stated at (35):

"The question of causation of injuries was not dealt with in Part 5 of the Guidelines but causation was addressed in Part 6, which related to assessment of permanent impairment. There is no reason to think that different principes were intended to be applied when a medical assessment was being made in relation to causation of minor injuries."

1. Wright J then described the Panel's role in a medical review which is to:

"Consider whether the motor accident did cause or contribute to (the claimant's condition). This requires, not a consideration of material derived as a result of an internet search... but rather a consideration of the material referred to in 5.6 of the Guidelines, namely all the evidence available to the Panel, including all relevant findings derived from:

(1) a comprehensive, accurate history, including pre-accident history and pre-existing conditions;

(2) a review of all relevant records available at the assessment;

(3) a comprehensive description of the injured person's current symptoms;

(5) diagnostic tests available at the assessment, noting that imaging findings that are used to support the assessment should correspond with symptoms and findings on examination."

1. The words "in the circumstances" in the context of whether the treatment is "reasonable and necessary" must refer to the particular circumstances of the claimant. This is because Schedule 2 of the Act refers to treatment "provided or to be provided to the claimant".
2. The test of "reasonable and necessary in the circumstances" does not direct attention to the relationship between the accident and the treatment. That issue arises from consideration of whether treatment "relates to the injury caused by the accident".

1. The parties have presented their respective bundles of documents upon which they rely. The Review Panel (Panel) has read all the documentation. If a particular document is not referred to by the Panel, this does not mean that the Panel, or a Panel Member, has not read it, nor taken it into consideration. The same principle applies to parties not referring to, nor specifically relying upon, a document in their own bundle and submissions.
2. The fact that evidence is not referred to in these reasons does not mean it has been overlooked. It is not required that each piece of evidence be mentioned. The Panel is not required to "analyse every piece of information from every opinion contained in a document with which it was provided". The Panel has come to its own conclusions and has taken its own history.

1. The claimant relied upon the following material which the Panel has considered:

These submissions are directed to the second accident on 12 October 2018.

MRI report of cervical spine and ultrasound of bilateral shoulder

This certificate relates to the second accident but is in identical terms to the previous certificate relating to the first (subject) accident.

The Panel notes this decision relates to the certificate of Medical Assessor Canaris pertaining to the second accident.

DRS Medical Assessment Certificate - minor injury (psychological)

Medical Assessor Newlyn certified that the subject accident caused the claimant to suffer a Post-Traumatic Stress Disorder which is not a minor injury for the purposes of the Act. Under the heading Causation, Medical Assessor Newlyn said as follows:

"Ms Semawy had no psychiatric symptoms before the February motor accident. The post-natal depression symptoms of 2014 had remitted spontaneously. She developed psychiatric symptoms immediately following the accident of 11 February 2018 beginning with an Acute Stress Disorder that progressed to post-traumatic stress disorder. With brief psychological counselling, the post-traumatic stress disorder remitted before the October 2018 motor accident that has resulted in the development of further psychiatric symptoms."

Medical Assessor Newlyn said that the claimant's post-traumatic stress disorder, which is not a minor injury, has resolved.

Dr George noted the history of the first and second motor accident. Dr George opined that the first accident appears to have been most severe and caused the most psychiatric sequalae. He gave a diagnosis under DSM-5 of chronic post traumatic stress disorder and persistent depressive disorder. His assessment of WPI under the psychiatric impairment rating scale (PIRS) for each accident was as follows:

Ms Semawy's presentation is consistent with that of Adjustment Disorder with Mixed Anxiety and Depressed Acute Mood. It also appears that Ms Semawy presents with features of post-traumatic stress disorder, including sleep disturbances, increased irritability/outbursts, impoverish concentration, hypervigilance, and exaggerated startled response.

I believe that Ms Semawy's condition is not the result of the motor vehicle accident on 12 October 2018 but (is) a re-triggering of psychological symptoms from a previous motor accident on 11 February 2018. I believe that Post-Traumatic Stress symptoms in particular may have already been present from the first accident given the nature and severity of the first accident. The pre-existing psychological symptoms from the first accident Ms Semawy reported to have significantly improved prior to the second accident.

Given the nature and severity of the second accident, that Ms Semawy was exposed to an event that post a serious threat to death or serious injury of not only herself but her children, that would have invoked a sense of intense fear and helplessness, I believe that it is a high probability that Ms Semawy would have experienced symptoms of similar nature and severity (i.e. Depression, Anxiety and Post-Traumatic Stress based symptoms) even without any pre-existing conditions.

1. The insurer relied upon the following material which the Panel has considered:

• Insurer's submission in reply to review application dated 28 March 2024 (February 2018 motor accident).

• Insurer's submissions in reply to review application dated 27 March 2024 (October 2018 motor accident).

• Insurer's submissions in reply to WPI dispute dated 18 July 2023

(a) The insurer submits there needs to be proper delineation and apportionment between the two accidents based upon the reliable historical evidence.

(b) The insurer notes the medical evidence relating to post-natal depression and anxiety prior to the February 2018 accident.

(c) The insurer notes there was no mention of psychological symptoms in the claimant's application for personal injury benefits relating to the February 2018 accident.

(d) The insurer references entries in the clinical records relating to injury suffered in the February 2018 accident and imaging performed on 2 May 2018 relating to the cervical spine, lumbar spine and both shoulders. The GP notes recorded continued complaint of pain in the neck, back and shoulder, as well as psychological complaints.

(e) The insurer references various consultations with the treating psychologist relating to severe Anxiety and Depression with signs of Active Stress Disorder relating to the first accident.

(f) The insurer notes that the claimant was seen by Medical Assessor Garvey on 25 November 2018 in relation to a minor injury dispute. Medical Assessor Garvey confirmed that the injuries to the cervical spine, lumbar spine and both shoulders were minor injuries and had resolved. He found no evidence of radiculopathy, annular tears or disc protrusions.

(g) The insurer references the certificate dated 18 March 2019 by Medical Assessor Thomas Newlyn who confirmed that the claimant's post-traumatic stress disorder was not a minor injury. The claimant informed the Medical Assessor that she had a significant personality change following the first accident and that the subsequent accident made everything worse. Medical Assessor Newlyn opined that the claimant had suffered an Acute Stress Disorder that progressed to post-traumatic stress disorder following the first accident which had remitted with brief psychological counselling, before development of further post-traumatic stress disorder symptoms following the second accident.

(h) The insurer references clinical notes of treatment at the Psych Central Psychological and Consulting Services following the second accident.

(i) The insurer notes the claimant was examined by Dr Michael Hong, psychiatrist, on 3 August 2021 for the insurer. Dr Hong opined the claimant suffered from anxiety and post-traumatic stress disorder from the first accident, which was aggravated by the second accident. The claimant reported to Dr Hong the first accident had a much bigger impact than the second accident. Dr Hong opined the claimant had not yet reached the maximum medical improvement for the purposes of a WPI assessment, and she would need to undertake further treatment before her injuries could be viewed as stable.

(j) The insurer notes it subsequently had the claimant examined by Dr Graham Vickery, psychiatrist, whose report dated 7 March 2023 noted ongoing symptoms of rumination, disturbed sleep and reduced hygiene. The psychological symptoms resulting from the first accident reportedly were exacerbated by the second accident. Dr Vickery was unable to provide a WPI assessment as he believed that the claimant's injuries were not stable. He thought the claimant would need further psychological treatment and use of anti-depressant medication for another twelve months.

• The claimant relies upon the report of Dr Graham George dated

13 September 2022. Dr George diagnoses chronic post-traumatic stress disorder and persistent depressive disorder as a result of both motor accidents. 15% WPI is given for each accident (thus a total of 30%). The insurer submits this is incorrect methodology and that the historical impairments from psychological symptoms (as suppose to physical) need to be independently assessed, apportioned and appropriate deductions applied.

• The insurer submits a number of the PIRS class scores given by Dr George are exaggerated. Dr George reports the same level of functioning across both accidents, despite commentary of the claimant that the second accident didn't bring much change to her symptoms. This is also at odds to the self-reports of the second accident as described to Medical Assessor Newlyn.
• The insurer also does not support the diagnosis of post-traumatic stress disorder. With mind to the determination in Jarvis v Allianz Australia Insurance Limited [2022] NSWSC 161, in order to meet the DSM-5 Criteria for post-traumatic stress disorder, there must be exposure to stressors such as death, threatened death, actual or threatened serious injury. The minor nature of the subject February 2018 accident, where the claimant's vehicle was clipped in an overtaking attempt, cannot meet the severity of an accident that meets the Criteria A for a post-traumatic stress disorder diagnosis.
• The insurer submits that close scrutiny of the Class ratings related to psychological symptoms, and when also applied with apportionment deductions, demonstrates that the clamant would not have a medium Class III rating and with the cumulative scores would therefore not exceed 10% WPI.
• Insurer's submissions in reply to WPI dispute dated 18 July 2023 (October 2018 accident).

The insurer makes the same submissions as in relation to the first accident

Documents in both claims - February 2018 and October 2018

1. The Panel conducts a new assessment of all the matters with which the medical assessment is concerned.[6]
2. The Panel is not required to choose between medical opinions and is required to form its own opinions.[7] The Panel's role is not to correct error in the decision of the original Medical Assessor.
3. The Panel adopts the Medical Assessors' examination report and adds the following further reasons.
4. As stated in the examination report, the Medical Assessors agree that the motor accident in October 2018 did cause an aggravation of the claimant's psychological injury arising from the subject accident in February 2018, with the claimant's major depressive disorder becoming clinically to the fore because of the second motor accident. It necessary follows that this case falls into second Oakley Category as previously described.
5. The Medical Assessors have explained the basis for their assessments and findings. The Medical Assessors respectfully note the views expressed by Medical Assessors' Canaris and Newlyn each of whom assessed the claimant some time ago.
6. The medical assessment of permanent impairment is made at the time of examination. In that respect, the assessments made by Dr George and Medical Assessor Canaris are outdated, and do not reflect current symptomatology, in the Medical Assessors' opinion. The diagnosis made by the Medical Assessors is similar to that made by Dr George and Ms Ali. The Medical Assessors note that neither of the insurer's qualified experts, Dr Hong and Dr Vickery, made an assessment of WPI.
7. The Panel is conscious that a strict interpretation of the Oakley principles would compel most of the Medical Assessors' assessment of WPI to be attributed to the subject February 2018 accident. However, as neither party has made submissions on the proper application of the Oakley principles to these claims, and as the same insurer is on risk for both accidents, the Panel believes that the strict application of the Oakley principles would yield an artificial result. The Panel prefers to apportion impairment between the two accidents in accordance with its examination findings.

1. For the above reasons, the Panel concludes the Certificate dated 21 February 2024 should be revoked. The new Certificate appears at the commencement of these reasons.
