Brexit: legal consequences for the EU

Dispute-settling between the EU and the UK
  • Nial Fennelly


The UK’s withdrawal from the European Union will have the most profound effect on legal relationships between the EU and the United Kingdom.

The purpose of this paper is to address the consequences in two principal respects:
  1. 1.

    Whether any judicial institution will be able to resolve disputes concerning the interpretation or effect of the withdrawal agreement reached under Art 50. The UK will not agree to the CJEU having jurisdiction. The case law of the CJEU says that it will. This will not, however, extend to disputes with the United Kingdom. The difference is due to the fact that the UK follows a dualist approach to the effect of international agreements.

  2. 2.

    The effects of withdrawal on existing judicial proceedings. The withdrawal of the UK from the EU will not affect the jurisdiction of the CJEU to decide cases whether references for preliminary ruling or infringement actions commenced before the date when the UK’s membership ends.
