Updated Debate Map: Brexit

This debate map indexes analysis of and information about the legal consequences of the Brexit, focusing specifically on the mechanics of leaving the EU and the impact on EU citizens in the UK and British citizens in the EU—as well as on trade, the environment, and human rights protection in the UK. The map also includes analysis of treaty withdrawal generally under international law and the extent to which obligations, particularly in the fields of human rights and trade, can be said to continue even after a state’s exit from a treaty.

The collection includes blog posts, papers prepared by the UK government, legal advice issued by leading lawyers, journal articles, and book chapters. Its purpose is to collect together legal analysis of the consequences of the Brexit under international law and EU law. 

We will be keeping this index up to date as developments unfold over the next weeks and months and may add coverage of new issues as appropriate.

Any comments on the content or organization of this map as well as suggestions for inclusion are welcome. Please send an email to merel.alstein@oup.com.
