I am delighted and truly honoured to be able to speak to you tonight to deliver the 2014 Mackenzie-Stuart lecture. President Barroso was speaking in London last Friday where he said: ‘The European Union would not have become what it is today if it weren’t for British politicians and entrepreneurs, British thinkers and British ideas’. Scholars from this University and from its Centre for European Legal Studies have contributed enormously. Looking just to the Union’s Courts, Judges Lord Mackenzie-Stuart, David Edward, Konrad Schiemann, Christopher Vajda and Nicholas Forewood, Advocates-General Francis Jacobs and Eleanor Sharpston are true architects of our Union.
