The Supreme Court of Canada on Thursday ruled unanimously that a partial privative clause cannot bar judicial review on questions of fact and law. It held that judicial review of such questions is the courts’ “core supervisory jurisdiction” guaranteed by the Constitution.
Chief Justice Richard Wagner, writing for the bench, held that Canada’s Constitution Act, 1867 guarantees the courts’ ability to review the legality of administrative decisions. He concluded that the legislature acts beyond its authority when it purports to limit courts’ constitutional power to perform a legality review. This is because, according to Wagner, any irrational or unreasonable exercise of public power is unlawful; the Constitution empowers courts to ensure that the government exercises its public power lawfully and within limits.
Notably, Wagner recognized the legislature’s power to prescribe procedures for judicial review. For instance, the legislature can regulate the timelines, fora or standards of judicial review. This power, however, cannot cut into the core supervisory jurisdiction of superior courts.
Sujit Choudhry, counsel for Democracy Watch, welcomed the decision:
In an era where executives around the world have sought to assert broad and unlimited powers that are not reviewable by the courts, the Supreme Court of Canada has resoundingly proclaimed that will not occur in Canada. In clear and unequivocal terms, the Supreme Court has affirmed legal powers, by definition, are limited powers, and that it is the constitutional duty of the provincial superior courts and the federal courts to rule on the legality of executive power.
The case concerns Section 66 of the federal Conflict of Interest Act. Known as a partial privative clause, the provision bars the federal court from reviewing the ethics commissioner’s decisions on the grounds of alleged factual or legal errors. Courts can still review commission decisions if there are alleged jurisdictional errors, procedural errors, or perjured evidence. Thursday’s ruling renders the section of no force and effect.
In May 2021, former ethics commissioner Mario Dion cleared former Prime Minister Justin Trudeau of conflict of interest violations related to his approval of WE Charity as the administrator of the Canada Student Service Grant. It was a temporary program that encouraged students to participate in service activities and support their communities during the COVID-19 pandemic. Democracy Watch, a Canadian advocacy group, argued that Dion failed to consider the personal ties between Trudeau and the Kielburger brothers, who are two of WE Charity’s co-founders.
The advocacy group lodged this judicial review to challenge the conclusion. The lower court threw out the case, holding that the reporting obligation owed by the commissioner to Parliament’s standing committee is an adequate alternative to judicial review. The apex court overturned this ruling.
The Federal Court of Appeal can now review Dion’s conclusion.

Executive Summary
The Supreme Court of Canada unanimously ruled that a partial privative clause cannot prevent judicial review regarding questions of fact and law, establishing this review as the courts’ core supervisory jurisdiction guaranteed by the Constitution. Chief Justice Richard Wagner noted that the Constitution Act, 1867 grants courts the ability to review the legality of administrative decisions. He contended that limiting the courts’ power to conduct legality reviews amounts to an overreach by the legislature, asserting that any irrational exercise of public power is unlawful and empowers courts to ensure government action is lawful and within limits.
The ruling specifically addressed Section 66 of the federal Conflict of Interest Act, a partial privative clause that previously barred federal courts from reviewing the Ethics Commissioner's decisions based on factual or legal errors. The court determined that while such clauses cannot limit core judicial review jurisdiction, the legislature retains the power to prescribe procedures for judicial review, such as setting timelines or standards. This decision impacts a prior challenge lodged by Democracy Watch against the conclusion reached by former Ethics Commissioner Mario Dion regarding conflict of interest violations involving Justin Trudeau and WE Charity. The ruling allows the Federal Court of Appeal to now review Dion’s conclusion, confirming that courts retain jurisdiction to examine administrative decisions for jurisdictional, procedural, or evidential errors, even where statutory clauses attempt to limit scope.
Full Take
The decision establishes a powerful structural defense for judicial oversight, asserting that the ability to review legality is fundamental rather than discretionary. The core tension analyzed here lies between legislative intent—the desire to allocate specific powers and procedures—and constitutional mandate—the judiciary’s role as the ultimate guarantor of lawful governance. When a legislature attempts to place a "privative clause" on judicial review, it attempts to relegate constitutional oversight into administrative or procedural boundaries, which the Court has rejected as an attempt to diminish the fundamental legality check necessary for administrative action.
The implication extends beyond this specific case concerning the ethics commissioner; it reinforces the principle that courts serve a supervisory role over executive power, not merely a rubber stamp for legislative will. The recognition that procedure can be regulated without curtailing core jurisdiction is a significant affirmation of judicial autonomy against legislative attempts to narrow oversight. For advocacy groups seeking accountability, this outcome suggests that legal challenges focused on procedural fairness or jurisdictional errors remain viable avenues to scrutinize executive decisions, regardless of statutory restrictions placed upon review mechanisms.
The pattern observed is the tension between delegated authority and inherent constitutional power. The narrative functions to defend the judiciary's structural role in a system where public power must be exercised lawfully; any attempt to carve out exceptions risks undermining the system’s capacity for accountability. The missing element often explored in such cases is the actual effect of procedural restrictions on substantive justice—does limiting review actually decrease the scope of scrutiny or merely shift the burden? What specific, measurable harms does this operational framework create when applied to high-stakes administrative decisions?
