VAVILOV - JR - SOR - Reasonableness Review - Justification - Evidence. Canada (Minister of Citizenship and Immigration) v. Vavilov
In Canada (Minister of Citizenship and Immigration) v. Vavilov (SCC, 2024) the Supreme Court of Canada revises the law of 'standard of review' ('SOR') for judicial reviews (JR) of administrative tribunal decisions and procedures. 'Standards of review' indicate the degree of deference that applies to the decisions of the lower court/tribunal/body - either on a JR or an appeal, by the reviewing body. The below extracts deal with 'reasonableness', the SOR for JRs - which are primarily addressed at errors by administrative tribunals - thus the term 'reasonableness review'.
The court states an oft-cited aspect of a 'reasonable' JR decision, that it is 'justified in light of it's legal and factual constraints', here it's 'evidence before the decision-maker':(d) Evidence Before the Decision Maker
[125] It is trite law that the decision maker may assess and evaluate the evidence before it and that, absent exceptional circumstances, a reviewing court will not interfere with its factual findings. The reviewing court must refrain from “reweighing and reassessing the evidence considered by the decision maker”: CHRC, at para. 55; see also Khosa, at para. 64; Dr. Q, at paras. 41-42. Indeed, many of the same reasons that support an appellate court’s deferring to a lower court’s factual findings, including the need for judicial efficiency, the importance of preserving certainty and public confidence, and the relatively advantageous position of the first instance decision maker, apply equally in the context of judicial review: see Housen, at paras. 15-18; Dr. Q, at para. 38; Dunsmuir, at para. 53.
[126] That being said, a reasonable decision is one that is justified in light of the facts: Dunsmuir, at para. 47. The decision maker must take the evidentiary record and the general factual matrix that bears on its decision into account, and its decision must be reasonable in light of them: see Southam, at para. 56. The reasonableness of a decision may be jeopardized where the decision maker has fundamentally misapprehended or failed to account for the evidence before it. In Baker, for example, the decision maker had relied on irrelevant stereotypes and failed to consider relevant evidence, which led to a conclusion that there was a reasonable apprehension of bias: para. 48. Moreover, the decision maker’s approach would also have supported a finding that the decision was unreasonable on the basis that the decision maker showed that his conclusions were not based on the evidence that was actually before him: ibid.
