Holding and result

The court struck the challenged paragraphs because Mr. McNeil's vocational opinions were founded on CAB PRO program outputs that were neither produced nor explained by their author, depriving the court and the defendants of the ability to scrutinize and cross-examine the source; outputs of a screening program do not constitute an admissible factual foundation for expert opinion absent proper foundation and opportunity for cross-examination.

Court disposition

Application granted

Orders

  • Paragraphs 49, 52, 80 and 285 of Mr. McNeil's report are struck.

Questions and positions

Legal issues

Party arguments

Applicant
Defendants argued that the CAB PRO outputs lack an adequate evidentiary foundation, are not diagnostic, the underlying answers and the entity producing the program results were not produced or made available for cross-examination, and therefore the paragraphs of McNeil's report that rely on those outputs should be struck.
Respondent
Plaintiff maintained that the CAB PRO is an accepted screening tool and that McNeil could legitimately rely on its outputs in forming vocational opinions; the report should therefore remain admissible.

Court’s reasoning

  1. 01

    General principles of admissibility of expert evidence; Supreme Court practice

    Expert opinion must be based on an admissible and examinable factual foundation and the source of opinion must be available for scrutiny and cross-examination

  2. 02

    CAB PRO documentation and court's finding in this decision

    Computer-generated screening-tool outputs are not diagnostic and cannot be used as an unquestioned factual foundation for expert opinion without proper foundation and ability to test the methodology and data

  3. 03

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

    Mohan criteria for admissibility of expert evidence (relevance, necessity, absence of exclusionary rules, proper qualification, and a proper basis) inform civil admissibility analysis

06

Ratio, limits and disposition

Ratio decidendi

The court struck the challenged paragraphs because Mr. McNeil's vocational opinions were founded on CAB PRO program outputs that were neither produced nor explained by their author, depriving the court and the defendants of the ability to scrutinize and cross-examine the source; outputs of a screening program do not constitute an admissible factual foundation for expert opinion absent proper foundation and opportunity for cross-examination.

Obiter and limits

  • CAB PRO is a useful clinical screening tool but explicitly not intended for diagnostic use and its raw data and author must be available if relied upon in litigation
  • A neuropsychologist or psychologist conducting an assessment should produce their underlying data and be available for cross-examination when their conclusions form the basis of another expert's opinion
  • Computer-generated conclusions, when presented as factual findings, amount to expert opinion and require the maker to be subject to examination

Court disposition

Application granted

  • Paragraphs 49, 52, 80 and 285 of Mr. McNeil's report are struck.

2025 BCSC 2624 Malhi v. Nissan

IN THE SUPREME COURT OF BRITISH COLUMBIA Citation: Malhi v. Nissan, 2025 BCSC 2624 Date: 20251008 Docket: M221834 Registry: Vancouver Between: Manpreet Katrina Kaur Malhi Plaintiff And Edger Cortez De Claro and Nissan Canada Inc. Defendants Before: The Honourable Justice Thomas Oral Ruling re admissibility of McNeil's report Counsel for the Plaintiff: B. Hambrook A. Maheem Counsel for the Defendants: J. Miller C. Morcom Place and Date of Trial/Hearing: Vancouver, B.C. October 8, 2025 Place and Date of Judgment: Vancouver, B.C. October 8, 2025 [1] THE COURT: This is an application by the defendant to strike out paragraphs 49, 51, paragraphs 80, and paragraph 285 of Mr. McNeil's report. [2] Mr. McNeil had the plaintiff fill out a neuropsychological test battery consisting of 17 psychological tests contained in a CAB PRO program. The answers provided by the plaintiff are not available; the answers were compiled within the CAB PRO program which then generated an opinion on the nature and extent of the plaintiff's cognitive deficits. These results are reproduced at paragraphs 85 and were summarized at paragraph 50 of McNeil's report. [3] The CAB PRO program is typically used as a screening tool in clinical practice, similar to an MMA exam, but obviously provides much more detailed and specific results. The program makes it clear that the results are not to be used for diagnostic

purposes. [4] In Mr. McNeil's report, he assumed that the functional limitations opined by the program to apply to the plaintiff were accurate and reflective of the plaintiff's cognitive functional limitations. He then utilized these limitations as a factual basis to provide an opinion on the plaintiff's vocational abilities and limitations. [5] I am troubled by the fact that the conclusions generated by the CAB PRO program form the factual basis for Mr. McNeil's opinion. Typically, such a factual basis would be provided by a neuropsychologist or psychologist after performing an extensive assessment which, of course, would be subject to some form of production and the practitioner who formulated the opinions would be made available for cross-examination. In this case, the court is left in the position of simply accepting that the functional limitations created by the CAB PRO program accurately represent the functional limitations of the plaintiff. [6] In my review, the results of such a battery of psychological tests constitute, with respect to the functional abilities of the plaintiff, an opinion on the functional capacity of the plaintiff. As such, the entity that has provided the opinion must be available to be cross-examined on their conclusions and/or opinion in some form. [7] I accept that the CAB PRO program is a useful tool for screening patients; however, I am not

satisfied that the output of the program is admissible as an accurate representation of the cognitive functional limitations of the plaintiff without providing a basis upon which the conclusions or results made and applied to the plaintiff can be scrutinized and subjected to cross-examination. Therefore, I am granting the defendant's application to strike paragraphs 49, 52, 80, and 285 from Mr. McNeil's report. "Thomas J."
