CLSGC’s 2014-15 Seminar Series on the theme of 'Beyond Pluralism? Co-Implication, Embeddedness and Interdependency between Public International Law and EU Law', co-convened by two members of the Centre, Dr Paul Gragl and Dr Violeta Moreno-Lax, concludes with this final workshop on Constructive Links or Dangerous Liaisons? The Case of Public International Law and European Union Law.


After an introductory roundtable discussion held in October 2014 on the general aspects of the relationship between EU law and PIL to set the scene, the project 'Beyond Pluralism? Co-Implication, Embeddedness and Interdependency between Public International Law and EU Law' opened in medias res, analysing specific legal areas from the viewpoint of both the EU and PIL in a series of ‘thematic dialogues’ (on monetary policy, energy and environmental law, human rights, crime, justice and terrorism, and common foreign and security policy), taking place from October 2014 to March 2015. An inductive methodology has been followed, based on direct observation of the respective thematic field, intended to allow contributors to draw conclusions on the actual processes of reception, compliance and/or contestation between the EU and international legal orders on that basis. This concluding two-day workshop will serve to put findings into perspective, reflect upon them and consider how best to articulate the link between the two regimes, possibly re-defining their relationship and offering a comprehensive account of their interaction, overcoming the limitations of monist, dualist and pluralist approaches.
