Holding and result

The report of Dr. Chawla was admissible because the Mohan criteria were satisfied: his specialized pain management expertise rendered his opinions relevant and necessary to issues of chronic pain and employment, no exclusionary rule applied, and s.12.1(2)(a) did not preclude admission in the circumstances of multiple separate actions; any duplication concerns affect weight, not admissibility.

Questions and positions

Legal issues

Party arguments

Applicant
Plaintiff submitted Dr. Chawla's report is admissible because he is a properly qualified physiatrist with a subspecialty in pain management, his opinions are relevant and necessary on chronic pain and employment issues, and his report differs materially from Dr. Adrian's physiatric report.
Respondent
Defendants argued the report is inadmissible relying on common law principles on expert evidence and s.12.1(2)(a) of the Evidence Act limiting expert evidence in vehicle injury proceedings and suggesting duplication with the existing report of Dr. Adrian.

Court’s reasoning

  1. 01

    R v Mohan, [1994] 2 S.C.R. 9

    Expert evidence admissibility requires relevance, necessity, absence of exclusionary rule, and proper qualification

  2. 02

    Evidence Act, R.S.B.C. 1996, c. 124, s.12.1(2)(a)

    Statutory limit on expert evidence in vehicle injury proceedings: max three experts and one report per expert per action, subject to section and regulations

  3. 03

    R v Mohan, [1994] 2 S.C.R. 9

    Trial judge has discretion to admit expert evidence applying Mohan; probative value may be excluded if outweighed by prejudicial effect

06

Ratio, limits and disposition

Ratio decidendi

The report of Dr. Chawla was admissible because the Mohan criteria were satisfied: his specialized pain management expertise rendered his opinions relevant and necessary to issues of chronic pain and employment, no exclusionary rule applied, and s.12.1(2)(a) did not preclude admission in the circumstances of multiple separate actions; any duplication concerns affect weight, not admissibility.

Obiter and limits

  • Plaintiff's involvement in four separate actions would, in theory, allow more experts than three per single action and s.12 case law on aggregation did not govern this ruling
  • Differences between Dr. Chawla's pain-focused diagnoses and Dr. Adrian's physiatric diagnoses support non-duplication
  • Issues of duplication and the weight to be given to overlapping expert evidence are matters for trial consideration

Court disposition

Report of Dr. Kshitij Chawla admitted as evidence

  • Dr. Chawla's expert report is admissible
  • Any issues of duplication or overlap with Dr. Adrian's report shall go to the weight of the evidence at trial

IN THE SUPREME COURT OF BRITISH COLUMBIA Citation: Bowden v.

Collins Counsel for the Defendants in Vancouver Registry Actions, S211322, M230153, M230154, and M230155: C.J. Keri L. Grant H. Dhatt, Articled Student Place and Date of Trial: Vancouver, B.C. September 11, 2023 Place and Date of Ruling with Written Reasons to follow: Vancouver, B.C. September 12, 2023 Place and Date of Written Reasons: Vancouver, B.C. November 24, 2023 [1] The plaintiff seeks damages in personal injury involving four different sets of defendants in four separate motor vehicle accidents which occurred on January 15, 2015, July 2, 2017, July 3, 2018, and September 27, 2019 (the "MVAs"). The plaintiff seeks a ruling on the

admissibility of Dr. Kshitij Chawla's report. There had already been a report prepared by Dr. Mark Adrian. Both physicians are physiatrists. While Dr. Adrian has some certification in connection with pain management, Dr. Chawla has a subspecialty in that area. [2] The defendants argue that Dr. Chawla's report is inadmissible, pursuant to the common law on experts and to the case law surrounding s. 12.1(2)(a) of the Evidence Act, R.S.B.C. 1996, c.

124. Section 12.1(2)(a) reads: Limitation on expert evidence in vehicle injury proceedings 12.1 [ ] (2) Except as provided under this section or the regulations, (a) a party to a vehicle injury proceeding, other than a fast track vehicle injury proceeding, must not tender the following at trial: (i) expert evidence on the issue of vehicle injury damages, of more than 3 experts; (ii) more than one report on the issue of vehicle injury damages from each expert referred to in subparagraph (i), [ ] [3] On Tuesday, September 12, 2023, I ordered that Dr. Chawla's report was admissible with brief reasons to follow. These are those reasons. [4] Expert evidence is admissible in accordance with in R. v. Mohan, [1994] 2 S.C.R. 9 at p. 20, where the Supreme Court of Canada set out the criteria to be: (a) relevance; (b) necessity in assisting the trier of fact; and (c) the absence of any exclusionary rule; and (d) a properly qualified expert. [5] In Mohan, Justice Sopinka, in writing for the Supreme Court of Canada, noted that relevance is a threshold requirement: p.

20. Under this criteria, it also considers the logical relevance of the evidence. Evidence that would be logically relevant may be excluded where the probative value is outweighed by the prejudicial effect, if inter alia: p. 21. [6] Considerations include whether the evidence is likely to assist in the fact-finding mission and where the opinion is necessary in the sense that it will provide information likely outside the experience and knowledge of a judge or jury: p. 23. [7] Section 12.1(2)(a) of the Evidence Act permits for the admission of three expert reports in relation to any one action. As noted here, the plaintiff was involved in four separate actions , which would enable the plaintiff to call 12 experts. I find that case law pertaining to s. 12 insofar as it considers the number of expert reports of similar experts in the situation does not govern this particular matter before the Court. [8] The question of whether to admit an expert opinion and report is a discretionary decision made by the court on the basis of the principles set out in Mohan. Those principles, as noted above, are whether it is helpful, necessary, and there is an absence of an exclusionary rule and there is a properly qualified expert. Here, I note that the existence of a diagnosis of chronic pain of the plaintiff and employment questions surrounding that issue will be key issues to be determined in

this case. Dr. Chawla has a specialty qualification in pain management, which is more comprehensive than a certification. No exclusionary rule prevents the reports admission and the question of the plaintiff's injuries is relevant to the assessment of damages. [9] Dr. Chawla noted in his report the following diagnoses: 1) chronic axial/mechanical low back pain likely secondary to multifactorial etiology, including myofascial pain syndrome, discogenic low back pain, and sacroiliac joint pain; 2) neck and upper back pain (resolved); 3) chronic comorbid insomnia for chronic mood disorder, suggestive of depression and anxiety and thus some had a focus in accordance with his subspecialty. [10] His diagnoses differed from the diagnosis of Dr. Adrian, which focused on the physiatric aspect of the injury suffered by the plaintiff, being mechanical neck, upper back, and lower back pain. [11] I am satisfied there were sufficient differences in the two reports reflecting Dr. Chawla's and Dr. Adrian's different areas of expertise with Dr. Chawla's focus in respect of pain while Dr. Adrian's focus in respect of the physiatric aspects of the MVAs. [12] In all of the circumstances, I find Dr. Chawla's report to be admissible. Any issues going to duplication will go to weight. "Maisonville J."
