I begin by saying that I am extremely grateful to the contributors to this book symposium for kindly having taken the time to read my book The Evolutionary Interpretation of Treaties, and to commit to writing their very stimulating views of it. Given the richness of the comments provided by my colleagues, it would I think be impertinent for me to do more, at this stage, than to try to set out the reflections that their comments have prompted with me.
In writing my book, one of the things I tried to do was to stress the striking interpretative potential with which the Vienna Convention rules are pregnant. It is worth remembering that when counsel for the United Kingdom in what Lord Hoffmann in Matthews  UKHL 4 at  referred to as ‘the great case of Golder’ tried to reign in the European Court of Human Rights, they did so by exhorting the Court that it was bound by the rules set out in Articles 31–33 of the Vienna Convention. It is safe to say that the strategy backfired.
