I spoke in December 2016 in Belfast to the Irish Centre for European Law and to the Northern Irish Judges on the subject of “Brexit and the Border”. The NI/RoI border is twice the length of the Anglo-Welsh border, and three times the length of the Anglo-Scottish border. My talk sought to identify some of the challenges that will be encountered for the movement of persons and of goods across the border after Brexit.
A summary of my remarks, and the accompanying PowerPoint presentation, are here.
