What is the standard of review for a question of mixed fact and law?

The parties agree on the appropriate standards of review. The standard of review on questions of law is correctness, while findings of fact and factual inferences are reviewable for palpable and overriding error: Housen v. Nikolaisen, 2002 SCC 33, [2002] 2 S.C.R. 235, at paras. 8, 10 and 25. A question of mixed fact and law involves the application of a legal standard to a set of facts, and is subject to review for palpable and overriding error, except for extricable questions of law: Housen, at para. 26. A question of law may be extricable from a question of mixed fact and law if, for example, the incorrect legal standard is applied, or a part of a legal test is not considered by the decision-maker. The extricable question of law is reviewed on a correctness standard.
