Will the following declaration from yesterday's Supreme Court of Canada opinion in Mission Institution v. Khela, 2014 SCC 24 quell the dissent?
This is doubtful. No authority is cited for the proposition, which (judging by the parties' factums) was not seriously argued in a case that turned on the scope of a common-law disclosure requirement and the relationship between the jurisdiction of the federal courts and provincial superior courts (more on those issues in future posts). [T]he standard for determining whether the decision maker complied with the duty of procedural fairness will continue to be “correctness”.
It is true that common law courts have typically professed no difficulty in stepping into the shoes of decision-makers when it comes to procedural matters. But on factual and policy matters falling within the specialized expertise of a decision-maker, it is clear, at least in Canada, that deference is now owed even on pure questions of law and constitutional matters.
Moreover, the Supreme Court of Canada recently noted that a full analysis of the standard of review is necessary "if the relevant precedents appear to be inconsistent with recent developments in the common law principles of judicial review" (para. 48).
If the standard of review of all procedural questions is correctness, then it is "inconsistent with recent developments".
Indeed, in a revealing slip, the Court itself deferred in part to the decision-maker's procedural determination in Khela:
The question of deference on questions of procedural fairness will continue to hang over Canadian administrative law until it is argued and authoritatively resolved by the Supreme Court. Section 27(3) authorizes the withholding of information when the Commissioner has “reasonable grounds to believe” that should the information be released, it might threaten the security of the prison, the safety of any person or the conduct of an investigation. The Commissioner, or his or her representative, is in the best position to determine whether such a risk could in fact materialize. As a result, the Commissioner, or the warden, is entitled to a margin of deference on this point. Similarly, the warden and the Commissioner are in the best position to determine whether a given source or informant is reliable. Some deference is accordingly owed on this point as well. If, however, certain information is withheld without invoking s. 27(3), deference will not be warranted, and the decision will be procedurally unfair and therefore unlawful. (Emphasis added)
