17 It is common ground that prior to the accident the first defendant had a substantial pre-existing condition in his lumbar spine and that the accident brought about injuries to both his cervical spine and his lumbar spine. There was also injury to the right shoulder. It does not seem to be regarded as being of significance. The task of the Assessor was to assess damages for the injuries caused by the fault of the owner or driver of the motor vehicle insured by the plaintiff.
18 The real issue was the extent to which his lumbar spine condition could be related to the accident. The stance taken by the plaintiff was that the accident had caused but a temporary problem and that such problem had ceased before the assessment.
19 At this stage it is convenient to briefly refer to the structure of the statement provided by the Assessor. The statement commences with introductory provisions and a recitation of issues. The recitation contains the following:-
"2.1. The injuries sustained in the MVA. In particular, the Claimant's lumbar spine condition manifesting in 2005/2006 and its referability to the MVA.
2.2. The extent of the Claimant's MVA related disability.
2.3. The measure of the Claimant's loss of earning capacity and its referability to the injuries and disabilities sustained in the MVA.
2.4. The measure of the Claimant's need for care and its referability to injuries and disabilities sustained in the MVA."
20 The recitation of issues is followed by a statement of the position of each party in relation to each head of damage (he was given a range in respect of each such head).
21 The Assessor then proceeded with the making of certain general findings of fact, which were said to be relevant to all issues (these included findings as to pre-accident condition, a recording that it came to be common ground that the first defendant suffered significant disability and could not be gainfully employed or looked after without care and that he had a poor prognosis).
22 The statement proceeds with the following:-
"2.5.4. In making the following findings of injury I rely on the Claimant's treating medical practitioners2 2 Dr Teychenne (neurologist) and Associate Professor Sheridan (neurosurgeon). and the MAS report of Dr M. Couch dated 20 March 2006.
2.5.4.1. Neck / aggravation of degenerative change / disc protrusion.
2.5.4.2. Back / aggravation of degenerative change / disc protrusion.
2.5.4.3. Right shoulder musculo ligamentous injury."
23 Under the heading of "Past Treatment" the Assessor proceeded to list the claims made in relation to that head of damage and what was in dispute. The statement then contains the following:-
"3.4. The Insurer generally submits I cannot be satisfied the disputed items relate to the injuries sustained in the MVA. Part of the submission being that they probably relate to the Claimant's lower back condition. The Claimant submits all his injuries and disabilities subsequent to the MVA are related to the MVA. It is common ground the Claimant's cervical spine condition is MVA related.
3.5. The Insurer submits the issue is whether the Claimant's "lumbar spine complications" occurring in 2006 is related to any aggravation sustained in the MVA or a continuation of the underlying degenerative condition which would have developed irrespective of the MVA. Further, it is the Claimant's lumbar spine condition that disables him most and not his cervical spine condition. Mr Fitzsimmons submits the preponderance of medical opinion including the MAS Assessor (Dr M Couch) support non-referability of the Claimant's lumbar spine condition.
3.6. Some of the medical opinions are not clear. However, Dr Kai Lee (orthopaedic surgeon), P. Teychenne (consultant neurologist) and Associate Professor M. Sheridan (neurosurgeon) appear to me to support the Claimant's contention that the MVA has materially contributed to the Claimant's lumbar spine condition and has caused the Claimant's cervical spine condition. My construction of Associate Professor Sheridan's opinion is that the MVA caused a disc prolapse resulting in cervical myelopathy symptoms materially contributing to both the Claimant's cervical and lumbar spine conditions.
3.7. Dr L. Pierides (occupational physician) (Insurer medico-legal) opines the Claimant's lumbar spine would have become evident in 2006 irrespective of the MVA. My interpretation of Dr N. McGill's (consultant rheumatologist) is that the Claimant's lumbar spine condition referable to the MVA would have disabled him for one or two years but his lumbar spine degenerative condition and the 1985 accident are the enduring causes of his current significant lumbar spine condition.
3.8. Dr M. Couch states inter alia the lumbar spine condition "cannot be related directly to the MVA'. However, Dr Couch also opines the MVA aggravated the Claimant's degenerative changes/disc protrusion. Dr Couch attributes 40% WPI to the Claimant's cervical spine and 1% to his right shoulder with 5% (all pre-existing) to his lumbar spine. This does tend to support the Insurer's submission although I am not satisfied Dr Couch supports the view the MVA was only a temporary aggravation until about January 2001 of the Claimant's pre-existing lumbar spine condition.
3.9. I am conscious that legal causation issues are not determined by medical opinion alone. Legal principles and the assessment or litigious process determine the issue Phan v Shui [2006] NSWCA 373. There are factors which, in my opinion support the Insurer's contention. The Claimant's 1985 lumbar spine injury, the lapse of time between the MVA and the lumbar spine manifestation in 2005/2006 (5-6 years) together with the Claimant's pre-existing back pain albeit relatively minor immediately before the MVA. My conclusion, however, is consistent with Mr Jobson's submission. I am satisfied the MVA did make a material contribution3 3 See March v Stramare Pty Ltd (1991) 171 CLR 506. to the Claimant's lumbar spine condition based on the opinion of the Claimant's treating medical practitioners especially Dr Teychenne and Associate Professor Sheridan. I am not satisfied Dr Couch's opinion is to the contrary although I acknowledge uncertainty in this respect.
3.10. I am also satisfied, however, that even without the intervention of the MVA the Claimant's lumbar spine condition was very precarious and was likely to have had a significant detrimental effect on his ability to work and live without some form of care in the future. I base this finding on the universal medical opinion the Claimant's lumbar spine condition was significant even before the subject MVA condition was evident."
24 The statement then proceeds to address other heads of damage (Future Treatment, Non-Economic Loss, Past Economic Loss, Future Economic Loss, Past Voluntary Services, Future Care, Holidays and Equipment).
25 Under the heading "Future Economic Loss", the statement contains, inter alia, the following:-
"7.1. Based on my findings the MVA has been the major contributor to the Claimant's inability to work in the construction industry6 6 The Claimant was variously a truck driver or concrete truck driver in that industry from the early 1990s. in any capacity for what would have been the rest of his working life."
26 Under the heading "Past Voluntary Services", the statement contains, inter alia, the following:-
"8.3. Since November 2005 I am satisfied the Claimant has needed personal care and domestic assistance because of his cervical spine and lumbar spine condition. On the basis of my findings on causation of the Claimant's lumbar spine condition I do not consider it necessary to determine the proportion of the Claimant's disability referable to the cervical spine and lumbar spine. The Claimant's disability to my mind is significantly caused by both conditions."
27 In 8.7 thereof, the Assessor set out his assessment of the reasonable and necessary voluntary care that the first defendant was given and which was referrable to the accident.
28 Under the heading "Future Care" the statement contains, inter alia, the following:-
"9.1 The claim is based on commercial 24 hours per day care for the Claimant's life expectancy9 9 On the median tables approximately 30 years. . The Insurer acknowledges the need for MVA related care at 7 hours per week. In making this submission the Insurer assumes the Claimant's lumbar spine condition is paramount in the Claimant's need for care and this is unrelated to the MVA. Because of my findings in paragraphs 3.6 and 3.7 I am compelled to reject that submission.
…
9.6 I find his current and likely future domestic care needs are as follows:
9.6.1. Assistance in the bathroom (principally toilet and showering). 1.5 hrs per day
9.6.2. Assistance in home transfers and Supervision including night supervision 2.5 hrs per day
9.6.3. Home care including emergency bedding Changes 0.5 hrs per day
9.6.4. Transport 0.75 hrs per day
9.6.5. Domestic duties including shopping 1 hr per day
9.6.6. Home property and motor vehicle cleaning 0.25 hr per day
____________
6.5 hrs per day
____________
6.5 hours per day at 45.5 hours per week. On the 5% tables for the next 10 years (412.9) on a current hourly rate of $21.41 this equates to 45.5 x 21.41 = $974.16 x 412.9 = $402,228.00 (rounded off).
9.7. At the end of the voluntary care period I anticipate the claimant will be approximately 65 years of age. In determining the fair and reasonable paid care requirement for the future in terms of hours per week I should and do take into account the probable need for care as a result of non-related MVA factors such as the Claimant's age and degenerative lumbar spine condition in his advancing years and allow a commercial hourly rate for reasonable care for approximately 20 years. The time involvement of commercial carers can be reasonably assessed to be at least the current voluntary care needs. It is not possible on the evidence to conclude the Claimant will need 24 hour care in ten years time nor the accurate form or cost of care. I am satisfied however, a fair and reasonable allowance should be for 50 hours per week at a current cost of $30.00 per hour1 11 This figure is taken from experience and the report of I. Davey. 1 = $1,500.00 deferred for 10 years 0.614 = $921.00 for 20 years on the 5% tables (666.4) = $613,754.00 (rounded off)."
29 The statement then provides an "Assessment of Damages Summary" which contains a component for future care (13.7. Future care $1,015,982).
30 The statement concludes with the assessment of "Costs and Disbursements".
