UK’s financial obligations to the EU post ‘no deal’ Brexit


Sean Aughey (together with Sam Wordsworth QC) was invited to give expert written evidence on public international law to the ‘no deal’ financial obligations enquiry conducted by the House of Lords sub-committee on EU financial affairs.

The questions posed by the committee focused on whether, as a matter of international law, the UK would have financial obligations to the EU in the event of a ‘no deal’ withdrawal from the EU Treaties becoming effective.

In their written submission, Sam Wordsworth and Sean Aughey explained that the UK would have certain crystallised financial obligations on withdrawal in a ‘no deal’ scenario pursuant to Article 50 of the Treaty on European Union as interpreted and applied consistent with Article 70 of the Vienna Convention on the Law of Treaties.

The written submission of Sam Wordsworth and Sean Aughey is available here.
