VAVILOV - JR - SOR - Reasonableness Review - Justification - Other Statutory or Common Law. 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 'other statutory or common law':(b) Other Statutory or Common Law
[111] It is evident that both statutory and common law will impose constraints on how and what an administrative decision maker can lawfully decide: see Dunsmuir, at paras. 47 and 74. For example, an administrative decision maker interpreting the scope of its regulation-making authority in order to exercise that authority cannot adopt an interpretation that is inconsistent with applicable common law principles regarding the nature of statutory powers: see Katz Group Canada Inc. v. Ontario (Health and Long‑Term Care), 2013 SCC 64, [2013] 3 S.C.R. 810, at paras. 45-48. Neither can a body instructed by legislation to determine what tax rate is applicable in accordance with an existing tax system ignore that system and base its determination on a “fictitious” system it has arbitrarily created: Montréal (City), at para. 40. Where a relationship is governed by private law, it would be unreasonable for a decision maker to ignore that law in adjudicating parties’ rights within that relationship: Dunsmuir, at para. 74. Similarly, where the governing statute specifies a standard that is well known in law and in the jurisprudence, a reasonable decision will generally be one that is consistent with the established understanding of that standard: see, e.g., the discussion of “reasonable grounds to suspect” in Canada (Transport, Infrastructure and Communities) v. Farwaha, 2014 FCA 56, [2015] 2 F.C.R. 1006, at paras. 93-98.
[112] Any precedents on the issue before the administrative decision maker or on a similar issue will act as a constraint on what the decision maker can reasonably decide. An administrative body’s decision may be unreasonable on the basis that the body failed to explain or justify a departure from a binding precedent in which the same provision had been interpreted. Where, for example, there is a relevant case in which a court considered a statutory provision, it would be unreasonable for an administrative decision maker to interpret or apply the provision without regard to that precedent. The decision maker would have to be able to explain why a different interpretation is preferable by, for example, explaining why the court’s interpretation does not work in the administrative context: M. Biddulph, “Rethinking the Ramifications of Reasonableness Review: Stare Decisis and Reasonableness Review on Questions of Law” (2018), 56 Alta. L.R. 119, at p. 146. There may be circumstances in which it is quite simply unreasonable for an administrative decision maker to fail to apply or interpret a statutory provision in accordance with a binding precedent. For instance, where an immigration tribunal is required to determine whether an applicant’s act would constitute a criminal offence under Canadian law (see, e.g., Immigration and Refugee Protection Act, S.C. 2001, c. 27, ss. 35 to 37), it would clearly not be reasonable for the tribunal to adopt an interpretation of a criminal law provision that is inconsistent with how Canadian criminal courts have interpreted it.
[113] That being said, administrative decision makers will not necessarily be required to apply equitable and common law principles in the same manner as courts in order for their decisions to be reasonable. For example, it may be reasonable for a decision maker to adapt a common law or equitable doctrine to its administrative context: see Nor-Man Regional Health Authority, at paras. 5-6, 44-45, 52, 54 and 60. Conversely, a decision maker that rigidly applies a common law doctrine without adapting it to the relevant administrative context may be acting unreasonably: see Delta Air Lines, at paras. 16-17 and 30. In short, whether an administrative decision maker has acted reasonably in adapting a legal or equitable doctrine involves a highly context-specific determination.
[114] We would also note that in some administrative decision making contexts, international law will operate as an important constraint on an administrative decision maker. It is well established that legislation is presumed to operate in conformity with Canada’s international obligations, and the legislature is “presumed to comply with the values and principles of customary and conventional international law”: R. v. Hape, 2007 SCC 26, [2007] 2 S.C.R. 292, at para. 53; R. v. Appulonappa, 2015 SCC 59, [2015] 3 S.C.R. 754, at para. 40. Since Baker, it has also been clear that international treaties and conventions, even where they have not been implemented domestically by statute, can help to inform whether a decision was a reasonable exercise of administrative power: Baker, at paras. 69-71.
