Okwuobi v. Lester B. Pearson School Board; Casimir v. Quebec (Attorney General); Zorilla v. Quebec (Attorney General), 2005 SCC 16, is a leading Supreme Court of Canada decision on minority language rights. The Court held that parents in Quebec who are denied access to English schools for their children must apply through the Administrative Tribunal of Quebec (ATQ), which holds exclusive jurisdiction to hear appeals regarding minority language rights, and cannot bypass the tribunal by applying to the courts. In examining the intent of the Quebec legislation the Court found that the tribunal also had the power to hear constitutional questions.
This decision was part of a trilogy of cases on minority language rights which included Solski (Tutor of) v. Quebec (Attorney General), 2005 SCC 14, and Gosselin (Tutor of) v. Quebec (Attorney General), 2005 SCC 15.
