The process of the UK’s withdrawal from the EU has presented and will continue in the coming years and decades to present many challenges.  One important question is what will happen to all of the international agreements to which the UK is party, or of which it enjoys the benefits, by virtue of its membership of the EU.  Those international agreements cover areas as diverse as air services, citizens’ rights, land transportation, nuclear cooperation, (political) partnerships, and trade.  They also take different forms: they comprise both “EU-only” agreements (negotiated and concluded by the EU alone in areas of its exclusive competence) and “mixed” agreements (concluded by the EU and its Member States in the fields of shared competence).  As the UK inches closer to “exit day”, and the EU and the UK prepare for signature and ratification of the Withdrawal Agreement, this discussion will explore how the Withdrawal Agreement provides for the continuation of these international agreements vis-à-vis the UK during the “transition or implementation period” (IP), and what will happen to them after the IP has come to an end.  It will also consider some of the other key features of the Withdrawal Agreement from the perspective of international law, including: the UK’s ability to negotiate, sign and ratify international agreements during the IP; the role of the Joint Committee established by the Withdrawal Agreement; and the provisions regarding the resolution of disputes that may arise between the UK and the EU.  Finally, it will explore some specific issues that arise in relation to a set of international agreements not directly provided for by the Withdrawal Agreement – intra-EU investment treaties – in the context of the UK’s departure from the EU.
