Weaving a Tangled Web:Hapeand the Obfuscation of Canadian Reception Law

Abstract

SummaryThe majority Supreme Court of Canada judgment inHape— a case concerning extraterritorial applicability of theCanadian Charter of Rights and Freedoms— is premised on three aspects of the relationship between international and Canadian law: (1) the interaction of customary international law and Canadian common law; (2) the role of Canada’s international legal obligations inCharterinterpretation; and (3) the potential role of customary international law as a source of unwritten principles of the Canadian Constitution. This article reviews pre-existing law in all three of these areas and analyzes a number of innovations apparently introduced thereto, with little or no explanation, by the majority inHape. It concludes thatHapeseriously exacerbates an already uncertain relationship between international and Canadian law, with fundamental consequences for the rule of law in Canada.
