The United Kingdom voted to leave the European Union back in June 2016. Yet, going on three years later, their departure has finally been scheduled for this March 29.
One of the benefits of the EU is the development of standards that permitted goods to travel between EU countries without being subjected to lengthy border checks for duties and to ensure that the goods meet the same regulatory standards.
While the UK and EU are engaged in efforts to develop a post-Brexit trade relationship, there is no guarantee such an agreement will be finalized.
Should it not be, the Irish Backstop, which would govern the passage of goods from the UK to Ireland, including across the Northern Ireland land border with Ireland, would come into play.
In this article, New York Times reporter Richard Perez-Pena does a nice job summarizing all that would be involved should the Irish Backstop ultimately need to be activated without having to build a wall.
