How to give the people of Northern Ireland a democratic say over the new legal arrangements that will apply to them under the Withdrawal Agreement? Given the deeply divided nature of Northern Irish society, this is a legal, political and constitutional conundrum. The WA, exceptionally for an EU/international treaty, sets out a complex mechanism regulating how the Northern Ireland Assembly may vote in the future to grant or withhold democratic consent to the terms of the WA as it applies to Northern Ireland. However, this mechanism may yet prove to be a recipe for future political conflict.

The decision of the Prime Minister Theresa May to stand down if the Parliament approves the Withdrawal Agreement has led a number of passionate proponents of Brexit including Boris Johnson to change their view of the deal. Still, the Democratic Unionist Party said on Wednesday that the Brexit deal and in particular the backstop posed ‘an unacceptable threat to the integrity of the United Kingdom.’ This is significant not only because the DUP is in a confidence-and-supply arrangement with the Government but also because a number of ardent Brexiteers such as Jacob Rees-Mogg have said that their stance towards the deal depends on DUP’s position. In light of another meaningful vote, one has to wonder whether the DUP’s fears concerning the threat of the backstop to the constitutional integrity of the UK are justified.
