In June 2016, the United Kingdom voted by a narrow margin in favour of leaving the European Union. This initiated an unprecedented political, economic, social, constitutional and legal crisis that continues unabated as the date of anticipated departure — March 29, 2019 — rapidly approaches. In this series, international law experts from Canada, the United Kingdom, Europe and the United States, comment on Brexit’s international and domestic law and governance implications. Their commentaries consider a wide range of subjects: trade, financial services, cross-border insolvency, intellectual property rights, environmental law and human rights. The analysis in this series should help politicians, policy makers, practitioners and civil society actors understand what is at stake in the Brexit negotiations, how to achieve a mutually satisfactory outcome to the negotiations, and what to do if such an agreement cannot be achieved.
