On 5 December 2013, the Oxford Public International Law Discussion Group had the honour of hosting a presentation by Professor William Schabas (Middlesex University London, Leiden University). Only a few days before the 65th anniversary of the adoption of the Universal Declaration of Human Rights, Professor Schabas spoke about the contemporary significance of the UDHR. He argued that not at least due to the prominent role given to it in the Human Rights Council’s Universal Period Review, the Universal Declaration is of unprecedented importance today. This contrasts with its legal status as a formally non-binding declaration. Drawing on his extensive research on the drafting history, which is the subject of his most recent publication with Cambridge University Press (The Universal Declaration of Human Rights: The Travaux Préparatoires, CUP 2013), Professor Schabas demonstrated to what point the form of the instrument was already controversial during the discussions leading up to its adoption. Does the contemporary importance of the Declaration call for a re-thinking of the traditional sources of public international law? This was one of the questions Professor Schabas’ fascinating talk raised, and that the audience explored in the ensuing discussion. A podcast is available for this talk (including the PIL Lunchtime Discussion Group series) on http://www.law.ox.ac.uk/themes/pil/media.php[linkme].
