Damages Must Flow From Aggravations of Pre-Existing Injuries

Reasons for judgement were released this week by the BC Court of Appeal confirming that judges must award damages when pre-existing conditions are aggravated in part due to a tortious cause.
In this week’s case (Sangha v. Chen) the Plaintiff was involved in a 2005 intersection crash.  Both the Plaintiff and Defendant were at fault for the incident.   The trial judge assessed damages on the basis that the Plaintiff sustained a two year soft tissue injury.  At the time of trial the Plaintiff had on-going chronic pain which was rooted in chronic depression which pre-dated the accident.  However, the Court found that the collision physical injuries “aggravated his previous depressed state” but did not assess damages for the on-going worsened depression finding that the Plaintiff “would have suffered his current symptoms in any event“.
In finding that this was in error and that damages needed to be assessed to reflect the collision caused aggravation of pre-existing depression the BC Court of Appeal provided the following reasons:
[26]        With respect, it does not appear to me to have been open to the judge to find, as she did in para. 110 that Mr. Sangha “would have suffered his current symptoms, in any event”, having found earlier in that same paragraph that “his physical injuries aggravated his previous depressed state”. Further, her conclusion that Mr. Sangha would have suffered his current symptoms appears to be inconsistent with her view expressed in para. 111 that “at most the injuries suffered in the accident aggravated the plaintiff’s mood symptoms”. Given that the “mood symptoms” are exactly those symptoms encompassed within the pre-existing condition of depressive illness, para. 111 appears to allow for attribution of at least a portion of Mr. Sangha’s current symptoms to the physical injuries sustained in the accident.
[27]        I recognize that one must not parse a trial judge’s reasons for judgment with too much exactitude, and so I have turned to the evidence relied upon by the trial judge, the medical report of Dr. Riar, in her determination that all of Mr. Sangha’s current malady derives from his pre-existing condition. Nowhere in that report does Dr. Riar entirely dissociate the current condition of Mr. Sangha from the accident, so as to support the judge’s conclusion that Mr. Sangha would have suffered his current symptoms, in any event. While Dr. Riar clearly considered that the preponderance of Mr. Sangha’s current symptoms derive from the pre-existing mental illness, Dr. Riar also said “I feel that the accident in question aggravated his mood symptoms, which in turn fed into his pains, and they have continued like that all along” and “The only thing the accident did was complicate his situation somewhat more”. Questioned about this, Dr. Riar affirmed this view of the reflection to at least a small degree, of the physical injuries in Mr. Sangha’s current malady:…
[29]        The correct approach to pre-existing conditions is discussed in Athey v. Leonati, [1996] 3 S.C.R. 458, under the rubric of “crumbling skull:
            The so-called “crumbling skull” rule simply recognizes that the pre-existing condition was inherent in the plaintiff’s “original position”. The defendant need not put the plaintiff in a position better than his or her original position. The defendant is liable for the injuries caused, even if they are extreme, but need not compensate the plaintiff for any debilitating effects of the pre-existing condition which the plaintiff would have experienced anyway. The defendant is liable for the additional damage but not the pre-existing damage: Cooper-Stephenson, supra, at pp. 779-780 and John Munkman, Damages for Personal Injuries and Death (9th ed. 1993), at pp. 39-40. Likewise, if there is a measurable risk that the pre-existing condition would have detrimentally affected the plaintiff in the future, regardless of the defendant’s negligence, then this can be taken into account in reducing the overall award: Graham v. Rourke, 74 D.L.R. (4th) 1; Malec v. J. C. Hutton Proprietary Ltd., 169 C.L.R. 638; Cooper-Stephenson, supra, at pp. 851-852. This is consistent with the general rule that the plaintiff must be returned to the position he would have been in, with all of its attendant risks and shortcomings, and not a better position.
[30]        I also refer to Blackwater v. Plint, 2005 SCC 58, [2005] 3 S.C.R., 2005 SCC 58.:
[78]      It is important to distinguish between causation as the source of the loss and the rules of damage assessment in tort. The rules of causation consider generally whether “but for” the defendant’s acts, the plaintiff’s damages would have been incurred on a balance of probabilities. Even though there may be several tortious and non-tortious causes of injury, so long as the defendant’s act is a cause of the plaintiff’s damage, the defendant is fully liable for that damage. The rules of damages then consider what the original position of the plaintiff would have been. The governing principle is that the defendant need not put the plaintiff in a better position than his original position and should not compensate the plaintiff for any damages he would have suffered anyway: Athey. …
[31]        I respectfully conclude that the judge erred in failing to reflect, in her damages award, her conclusion of fact that “the physical injuries aggravated his previous depressed state” and “the accident did cause at least some of” the psychological symptoms. To what extent the damages should have been adjusted to account for these conclusions I cannot say. That question is one particularly within the purview of a trial judge. Accordingly, in my view, the award of damages must be set aside and the issue of quantum of damages must be remitted to the Supreme Court of British Columbia for fresh assessment.

$85,000 Non-Pecuniary Damages Assessment for Chronic Pain Syndrome

Adding to this site’s archives of chronic pain cases, reasons for judgement were released last week by the BC Supreme Court, Vancouver Registry, assessing damages for chronic pain syndrome.
In last week’s case (Perry v. Perry) the Plaintiff was involved in two motor vehicle collisions.  She suffered from pre-existing health problems including PTSD and chronic pain.  She was injured in both collisions and this aggravated her pre-existing difficulties and caused new ones.  Ultimately she was diagnosed with a Chronic Pain Syndrome with a poor prognosis.  In assessing her non-pecuniary damages (money for pain and suffering and loss of enjoyment of life) at $85,000 Mr. Justice Melnick made the following findings:

41] Ms. Perry is a person who had had a number of challenging health issues prior to the first accident. Those issues included PTSD, which related to her childhood abuse, and problems with her feet and legs. She sometimes suffered from depressive episodes and had a history of alcohol and heroin abuse. She had multiple areas of pain that she experienced at least as far back as 2003. I conclude that, prior to the first accident, she was a person of some fragility with respect to both her physical and emotional health, likely the seeds of which were sown by her tragic childhood and exacerbated by her alcohol and drug use.

[42] That said, Ms. Perry, in the few years prior to the accident, had made real progress by putting her addictions behind her and, to a certain extent at least, engaging in life through education, volunteer work and a small amount of employment. She was, however, what I would describe as a “thin-skull” case: more at risk for emotional and psychological trauma than a normal person without Ms. Perry’s medical history would be: Athey v. Leonati, [1996] 3 S.C.R. 458. See also: Hussack v. School District No. 33 (Chilliwack), 2009 BCSC 852 at para. 143; . Thus, while the average otherwise healthy individual involved in the same type of accidents that Ms. Perry experienced may have suffered similar physical injury, that person would not be at the same risk of suffering the same psychological damage as Ms. Perry.

[43] I am satisfied that Ms. Perry suffers from chronic pain, which is largely attributed to the first accident, and to a minor extent to the second accident. She was not without pain and physical problems before these accidents and the defendants are not responsible for the extent to which those symptoms were already symptomatic: Athey at para. 35…

[51] Ms. Perry has several health issues, a large portion of which are attributable to these two accidents. Taking into account, as I have, that some of her current health situation is attributable to her past medical problems, I asses her overall non-pecuniary damages at $85,000. The seriousness of Ms. Perry’s injuries and her guarded prognosis are more in line with the authorities suggested by counsel for Ms. Perry.

Reduction of Damages for Contributing Effects of Pre-Existing Conditions in BC Injury Claims


In BC Injury Claims (tort claims) a damage award can be reduced to account for the extent that a pre-existing condition contributes to a subsequent impairment.  Reasons for judgement were released today by the BC Court of Appeal discussing this area of law in the context of a jury trial.
In today’s case (Laidlaw v. Couturier) the Plaintiff was involved in a 2004 motor vehicle accident.  The Plaintiff suffered from various pre-existing difficulties including depression.  He was injured in the car accident and following a Jury Trial his damages were assessed at $128,717.  The Jury went on to reduce this award by 85% to take into account the “measurable risk that the plaintiff would have suffered from the (post accident) physical and psychological complaints even if the (car accident) had not happened“.
The Plaintiff appealed this jury award arguing that the trial judge made a mistake in having the Jury give a general ‘across the board’ reduction of damages for the risk of difficulties the pre-existing conditions may have posed.  The BC Court of Appeal agreed that the trial judge did indeed err in instructing the Jury and ordered a new trial.  In coming to this conclusion the BC high court extensively discussed the law of reduction of damages to account for risks of pre-existing conditions.  The highlights of this discussion were as follows:

[42] Ultimately, this appeal turns on a significant error exposed in the jury charge, in the third jury question, and the ultimate verdict.

[43] As can be seen from the emphasized portion of the jury charge recited in paragraph 26 of these reasons, the trial judge instructed the jury that if they found that “if the May 2004 accident had not happened there was a material risk that Mr. Laidlaw would nevertheless have suffered from general anxiety or depression or back problems, then you should reduce Mr. Couturier’s liability by the amount of that material risk, whatever you find it to be.”…

[47] The wording of question 3, together with the judge’s charge on causation was overly simplistic.  The various conditions from which the plaintiff had suffered previously, and the symptoms to which they gave rise, were not capable of reduction to a single “measurable risk”.

[48] One, some or none of those previous conditions might have “detrimentally affected the plaintiff in the future”.  One or more of those conditions might have affected him at different points in time.  The degree to which each such condition might have affected him need not have been identical.

[49] To lump these variables together into one question and to invite a single mathematical adjustment was unfair and inappropriate.

[50] Athey was a case with a single identifiable injury, a disc herniation, occurring some months after the accidents giving rise to the plaintiff’s claim.  There was a single pre-existing condition, “a history of minor back problems”, which was alleged to have contributed to his injury.  I do not read the language in Athey, while appropriate to the kind of case with a single measurable risk, to be transferable to the facts of a more complex case such as this one, which involves the assessment of multiple and distinct measurable risks.

[51] The contributing effects of a pre-existing condition to a subsequent injury can be taken into account if the trier of fact considers that to be appropriate.  In many cases, it may well be a relevant factor for the jury to consider.  However, the jury should be told that the effect to be given to such a “measurable risk” should be carefully related to the specific facts of the case.  In a case such as this, where there were various pre-existing conditions, and where it was uncertain if, when, or to what degree those conditions might adversely affect the plaintiff in future, it was an error to invite a general reduction across the board, as is required by question 3.

[52] In my opinion, the first portion of the charge on causation and in question 3 directed the jury to undertake a formulaic approach to the assessment of damages attributable to the defendant rather than directing them to consider, in a nuanced fashion, all of the contingencies and risks inherent in Mr. Laidlaw’s individual circumstances and to arrive at a global assessment of damages.  Question sheets such as this one that ask the jury to answer questions that tend to reveal their deliberations are not helpful, invite appeals, and are to be avoided.

[53] It must be said that the second portion of the trial judge’s written instructions did not mirror the wording in question 3.  However, it stands to reason that by the time the jury was completing its deliberations, their focus must have been on the question sheet.  Question 3 is clear in its terms but, unfortunately, incorrect in its legal effect.  In my view, it amounts to misdirection…

[58] In the end, it is impossible to say with confidence that the jury properly understood its task in assessing the damages due to Mr. Laidlaw.  In my view, the only recourse available is to order a new trial.

More on ICBC Tort Claims and Pre-Existing Injuries

How is a claim for compensation affected if you suffer from pre-existing injuries and as a result of the fault of another have your injuries aggravated?  If your injuries would have deteriorated eventually without the intervening event your claim for damages can be adjusted accordingly.  This is sometimes referred to as the ‘crumbling skull’ principle and reasons for judgment were released today by the BC Supreme Court, New Westminster Registry, applying this point of law.
In today’s case (Jopling v. Bradowich) the Plaintiff was injured in a 2004 BC Car Crash.  The Plaintiff’s accident related injuries included headaches, disturbed sleep, depression and chronic pain.  However, the Plaintiff suffered from pre-existing problems which were summarized by Mr. Justice Rice as follows: “ I am satisfied that the plaintiff suffered from pre-existing injuries to her lower back prior to the motor vehicle accident, and that there was a general degeneration of her spine, all of which were likely to lead her to the condition that she now experiences, although probably not as soon as it did because of the accident.”
The Court valued the Plaintiff’s non-pecuniary loss (pain and suffering) at $75,000 but then reduced this award by 20% to ‘reflect the contingencies that her back and shoulder pain would have manifested regardless of the accident‘.
In reaching this conclusion Mr. Justice Rice made the following observations of the law of causation in BC personal injury claims:

29] The principal issue in this action is whether the plaintiff’s individual injuries were caused by the accident, or whether they were only aggravations of pre-existing injuries.

[30] Proof of causation is determined by the “but for” test: Athey v. Leonati, [1996] 3 S.C.R. 458, at para. 14; Hanke v. Resurfice, 2007 SCC 7, [2007] 1 S.C.R. 333, at para. 21). If I find that “but for” the defendant’s conduct the plaintiff would not have been injured, then the defendant is liable for all the damages flowing from those injuries.  If the conduct of the defendant is unrelated to the alleged loss, then the defendant is not liable.

[31] It is no answer to a plaintiff’s claim for damages that he or she would have suffered less injury or no injury at all had he or she been less susceptible.  If an individual has a pre-existing condition, the person who injures that individual must take him or her as found: Athey, at para. 34.

[32] However, if the plaintiff’s injuries would have manifested themselves on their own in the future regardless of the defendant’s conduct, the court must apply a contingency factor to address that possibility.  Such a contingency does not have to be proven to a certainty.  Rather, it should be given weight according to its relative likelihood: Athey, at para. 35.

$40,000 Pain and Suffering Awarded for TMJ, Hip Injury and STI's

Reasons for judgement were released yesterday by the BC Supreme Court (Pavlovic v. Shields) awarding a Plaintiff just over $134,000 in total damages as a result of injuries sustained in 2 separate motor vehicle collisions.
The first collision was in 2006 and the second in 2007.  Both were rear-end crashes and the Plaintiff was faultless in both collisions.  Often in ICBC Injury Claims involving multiple collisions where fault is not at issue damages are assessed on a global basis and that is what occurred in this case.
Mr. Justice Rice found that the Plaintiff had pre-existing back and shoulder pain before these accidents that that even without these accidents the Plaintiff would have continued to have pain in these areas.  The Court made the following findings with respect to the Plaintiff’s injuries and awarded $40,000 for her non-pecuniary loss (pain and suffering / loss of enjoyment of life):

[59]            In this case, the plaintiff had back and shoulder pain pre-dating both accidents.  This is a “crumbling skull” situation.  It is more probable than not that the plaintiff would have experienced ongoing problems with back pain, for which she had already seen a Dr. Ansel Chu on several occasions in 2003.  The plaintiff claims these injuries were fully resolved, and relies on Dr. Chu’s report of August 14, 2003, in which he states that the plaintiff had had good relief from pain following a series of trigger point injections.  However, Dr. Chu does not state that her injuries had resolved, merely that she was “doing quite well” and that she could make a further appointment with him if the pain flared up again.  That the plaintiff made no further appointments is likely explained by the fact that she went to Europe for an extended period shortly after her last appointment with Dr. Chu. 

[60]            The evidence from Dr. Petrovic’s report is that only two permanent injuries from the accidents are likely: the TMJ and the right hip.  He would defer to the experts on those and has a guarded prognosis for the remainder of her injuries.  Dr. Epstein testified that the TMJ injury is likely to improve with continued treatment.  Dr. Smit was of the opinion that the right hip would require surgery.   

[61]            I accept that the plaintiff had no pre-existing hip or jaw complaints and that these are her principal injuries.  The hip may require surgery and her jaw will require ongoing management and treatment.  The defendants are fully liable for these injuries.  Her other injuries – the neck, shoulder and back pain – are likely to improve over the next year.   The effects of the concussion resolved nine months after the accident.  Taking these factors into account, I consider an award of $50,000 in non-pecuniary damages appropriate in the circumstances, the bulk of which reflects the injuries to the jaw and hip, discounted by 20% to reflect the plaintiff’s pre-existing chronic back pain, for a total of $40,000.

Mr. Justice Rice also did a good job explaining 2 legal principles which often arise in ICBC Injury Claims – the ‘thin-skull’ principle vs. the ‘crumbling skull’ principle.  He summarized these as follows:

[54]            The defendant does not go so far as to deny that the accident caused or contributed to the plaintiff’s injuries.  The concern is as to the extent.  The issue is whether this is a “thin skull” or a “crumbling skull” situation.  Both address the circumstances of a pre-existing condition and its effect upon the accident victim.  The law is that the defendant need not compensate the plaintiff for any debilitating effects of a pre-existing condition if the plaintiff would have experienced them regardless of the accident: Athey v. Leonati, [1996] 3 S.C.R. 458 at para. 35, 140 D.L.R. (4th) 235.  The court requires “a measurable risk” or “a real or substantial possibility and not speculation” that the pre-existing condition would have manifested in the future regardless of the plaintiff’s negligence.  The measurable risk need not be proven on a balance of probabilities, but given weight according to the probability of its occurrence: Athey v. Leonati, at para. 27.

[55]            The injury is deemed “thin skull” when there is a pre-existing condition that is not active or symptomatic at the time of the accident, and that is unlikely to become active but for the accident.  If the injury is proven to be of a thin skull nature, then the defendant is liable for all the plaintiff’s injuries resulting from the accident. 

[56]            A “crumbling skull” injury is also one where there is a pre-existing condition, but one which is active or likely to become active regardless of the accident.  If the injury is proven to be of a crumbling skull nature, then the plaintiff is liable only to the extent that the accident caused an aggravation to the pre-existing condition.
