Vavilov: How Courts Review Tribunal and Government Decisions
If you challenge a tribunal or government decision in court, Vavilov tells you what the court will look for. Here is the framework, in plain language.
Canada (Minister of Citizenship and Immigration) v. Vavilov, 2019 SCC 65, is the Supreme Court of Canada's leading decision on judicial review: how courts review decisions made by tribunals and government officials.
Courts usually ask whether a decision was reasonable: whether it is justified, transparent and intelligible, given the facts and the law. Some questions, such as constitutional issues, get a stricter "correctness" review.
What happened
Alexander Vavilov was born in Toronto. His parents, it later turned out, were Russian spies living under false Canadian identities. The Registrar of Citizenship cancelled his citizenship, relying on an exception for children of foreign government employees. The Supreme Court held the decision was unreasonable: the exception didn't apply to him.
What the court decided
- Reasonableness is the presumed standard of review.
- Correctness applies to constitutional questions, general questions of law of central importance to the legal system, and questions about the boundaries between different decision-makers.
- Where the law gives a right of appeal to a court, ordinary appeal standards apply.
What "reasonable" means
A reasonable decision:
- follows a rational chain of reasoning;
- fits the law and the evidence;
- responds to the parties' key arguments.
What it means for you
- Before going to court, use any internal review or appeal the tribunal offers.
- Point to specific gaps in the reasoning, not just disagreement with the result.
- Watch the deadlines: judicial review applications in Ontario usually must be started within 30 days.
