This article explores some aspects of the Canadian Supreme Court’s decision on Nevsun Resources v Araya in the light of its exposition on the act of state doctrine and application of core human rights as an integral aspect of international customary law and common law. It examines the Nevsun decision in the context of recent statutory developments in France and the Netherlands, the promised law reform in the European Union, and the proposed business and human rights treaty. I argue that it is high time to abandon the doctrinal fossil that human rights obligations do not apply to corporate governance and operations. It is hoped that COVID-19 contexts, and a post-pandemic world, will expeditiously result in the willing adoption of a treaty on business and human rights.
