Background
Nadine Muhanna obtained Canadian citizenship in 2008. Her file was subsequently discovered as part of a fraud investigation into Nizar Zakka and his firm, Décision Immigration 2000 Inc., a citizenship consultancy operating a scheme to simulate residence in Canada. Documents seized from the firm included Ms. Muhanna’s 2005 Lebanese passport bearing the handwritten annotation “à ne pas déclarer” (“not to be declared”), along with stamps demonstrating travel in 2005, 2006, and 2007 that were not disclosed in her citizenship application. The evidence suggested she had materially understated her absences from Canada during the four-year residency period preceding her application.
The Minister of Citizenship and Immigration first initiated revocation proceedings against Ms. Muhanna in 2011. The process was restarted twice following legislative amendments, including a 2017 finding by the Federal Court that the then-existing revocation scheme was constitutionally inoperable under paragraph 2(e) of the Canadian Bill of Rights. In May 2024 the Minister sent a Request for Information Letter, and in July 2024 issued a formal notice under subsection 10(3) of the Citizenship Act. Ms. Muhanna responded, signed a form electing to have the Minister—rather than the Federal Court—decide her case, and requested full disclosure of the Décision Immigration 2000 Inc. files. In October 2024, a Senior Analyst acting as the Minister’s delegate revoked her citizenship.
Ms. Muhanna sought judicial review on three grounds: (1) that the Minister’s failure to disclose the entirety of the seized files violated the common law duty of procedural fairness; (2) that thirteen years of proceedings amounted to an abuse of process; and (3) that the revocation decision was unreasonable on its merits.
The Court’s Holding
Justice McHaffie dismissed the application on all three grounds. On disclosure, the court held that paragraph 10(3)(c) of the Citizenship Act—which requires the Minister’s notice to set out “the specific grounds and reasons, including reference to materials, on which the Minister is relying”—exhaustively defines the Minister’s disclosure obligations when a person elects the ministerial decision-making route. Relying on Ocean Port Hotel Ltd v British Columbia, 2001 SCC 52, and the Federal Court of Appeal’s recent decision in Tan v Canada (Citizenship and Immigration), 2026 FCA 36, the court held that clear statutory procedural requirements oust the common law duty of fairness. A person who chooses to have the Minister decide their case—rather than requiring referral to the Federal Court, where full discovery rights apply—does so with notice of the Minister’s limited disclosure obligations and cannot afterward claim entitlement to broader disclosure. The court expressly declined to follow Ibrahim v Canada (Citizenship and Immigration), 2025 FC 2010, which had reached the opposite conclusion, finding that Tan (FCA) had undermined Ibrahim’s reasoning.
On delay, the court held that while the thirteen-year process was lengthy, Ms. Muhanna had not demonstrated that the delay caused her significant prejudice in her ability to respond to the Minister’s allegations—the threshold required to establish an abuse of process in an administrative context, per Law Society of Saskatchewan v Abrametz, 2022 SCC 2. Without demonstrated prejudice to the ability to mount a defence, prolonged delay, however inordinate, does not by itself constitute an abuse of process warranting a stay. On the merits, the court found that Ms. Muhanna’s substantive arguments were largely a restatement of her procedural fairness and delay arguments and did not reveal any logical or factual error rendering the Minister’s decision unreasonable.
Key Takeaways
- When a citizenship-revocation respondent elects under paragraph 10(3.1)(b) of the Citizenship Act to have the Minister decide their case, the Minister’s disclosure obligation is limited to what paragraph 10(3)(c) requires — setting out the specific grounds, reasons, and materials relied on — and the common law duty of procedural fairness cannot expand that obligation.
- The Federal Court of Appeal’s binding decision in Tan, 2026 FCA 36, confirms that the revocation scheme as a whole is procedurally fair and constitutionally valid: a person who wants the fuller procedural protections of discovery and disclosure may obtain them by not requesting ministerial adjudication, thereby triggering a Federal Court action under subsection 10.1(1).
- Delay in administrative revocation proceedings does not constitute an abuse of process unless the affected person demonstrates actual, significant prejudice to their ability to respond to the allegations; length of delay alone is insufficient to warrant a stay.
- Ibrahim, 2025 FC 2010 — which held that the common law duty of fairness imposes disclosure obligations on the Minister beyond the statute — has been effectively overtaken by Tan (FCA) and should not be followed.
Why It Matters
This decision clarifies a contested area of Canadian citizenship law: the scope of disclosure owed to individuals facing revocation who invoke the ministerial decision-making route. By holding that the statutory framework is self-contained and displaces common law fairness norms, the court resolves a conflict between two Federal Court decisions (Tan and Ibrahim) and firmly anchors disclosure obligations to the text of the Citizenship Act. Practitioners advising clients in revocation proceedings must now account for the fact that electing ministerial adjudication means foregoing the discovery rights available in a Federal Court action — a strategic choice with significant evidentiary consequences.
More broadly, the ruling reaffirms the Ocean Port principle that clear parliamentary choices about procedural design prevail over judge-made fairness requirements, absent a constitutional violation. It also signals that courts will scrutinize abuse-of-process delay arguments carefully, requiring concrete evidence of prejudice rather than relying on the mere passage of time — even where, as here, proceedings spanned more than a decade and were restarted multiple times following legislative reforms.
