Philippe Sands, Professor of Law at University College London, came to the Lauterpacht Centre on Wednesday 2 November 2016, to discuss some of the issues arising from his latest book, 'East West Street: On the Origins of Genocide and Crimes Against Humanity' (Weidenfeld & Nicolson, 2016). The conversation was led by Dr Sarah Nouwen (LCIL Deputy Director) and Dr Franziska Exeler (Faculty of History, University of Cambridge), and was followed by questions from the floor.
