In HLP Solution Inc. v. The Queen (2015 TCC 41 ) the Tax Court held that a CRA employee lacked the necessary impartiality to testify as an expert witness because of her prior involvement in auditing the taxpayer.
Background
The taxpayer was a software company that claimed Scientific Research and Experimental Development (SR&ED) tax credits for the 2009 taxation year. The CRA reassessed to deny the SR&ED credit claims.
In the Tax Court, the taxpayer challenged the qualification of the CRA's expert witness on the basis that she did not have the necessary impartiality to testify as an expert witness in the appeal. The Tax Court held a voir dire to determine whether the Crown's proposed expert witness could testify in the appeal.
The proposed expert witness held a doctorate in computer science and was employed with the CRA as a Research and Technology Advisor (RTA). The taxpayer's allegation of impartiality was not based on the fact that the proposed expert witness was employed with the CRA. Rather, the taxpayer argued that it was the proposed expert witness's involvement in every stage of the file that impugned her impartiality.
The Crown submitted that it is rare for a court to refuse to hear the testimony of an expert witness, and that there must be clear evidence of bias, which, according to the Crown, was not present in this case. Moreover, the Crown submitted that it was in the capacity as an expert that the opinion was given, irrespective of whether this occurred at the audit stage, objection stage, or during appeal.
Analysis
In analyzing whether to admit the evidence by the Crown's witness, the Tax Court reviewed the leading case on the admission of expert evidence, the Supreme Court of Canada decision R. v. Mohan ([1994] 2 SCR 9), in which the Court set out the criteria for determining whether expert evidence should be admitted, namely: relevance, necessity in assisting the trier of fact, the absence of an exclusionary rule, and a properly qualified expert.
In Mohan, the Supreme Court established that the question of relevancy is a threshold requirement for the admission of expert evidence and a matter to be decided by the judge as a question of law. There must first be logical relevance in order for the evidence to be admitted. The judge must then perform a cost-benefit analysis to determine whether the value of the testimony is worth the costs, in the sense of its impact on the trial process.
The Tax Court also reviewed R. v. Abbey (2009 ONCA 624), in which the Ontario Court of Appeal applied Mohan but also distinguished between the preconditions to admissibility and the judge's role as a gatekeeper. The Ontario Court of Appeal noted that while the inquiry into the preconditions to admissibility is a rules-based analysis that tends to yield "yes" or "no" answers, the gatekeeper function does not involve the application of bright line rules and frequently requires the exercise of judicial discretion. The gatekeeper function is more subtle and involves weighing the benefits of the probative value of the evidence against the prejudice associated with admitting the evidence.
In HLP, the Tax Court held that it was preferable to disqualify the expert at the qualification stage. The Court based its conclusions on many of the taxpayer's allegations, including the following:
- the proposed expert witness was involved with the audit and objection;
- the proposed expert witness delivered the opinion (the technical review report) that served as the basis for the assessment;
- following the taxpayer's representations, the proposed expert witness also wrote an addendum to the technical review report in which she maintained the same position;
- the proposed expert witness participated in every meeting with the taxpayer as the CRA's representative;
- the proposed expert witness confused her role as an RTA with that as an expert witness; and
- the proposed expert witness reproduced word-for-word paragraphs from her technical review report.
The Tax Court was careful to note that it was not disqualifying the expert on the basis of her employment with the CRA but rather on the basis of her close involvement throughout the audit and objection stages of the file.
The Tax Court allowed the Crown to submit a new expert report.
The Tax Court's decision in HLP will have a direct impact on future cases in which proposed expert witnesses were involved in the audit and objection processes as CRA employees. Such employees – though they may have the required professional qualifications to testify as an expert witness – cannot be qualified as expert witnesses because they lack the necessary impartiality to testify.
