Mario’s primary scholarly interests lie in the area of international law and organisations, with particular interest in critical legal theories, sustainable development and the resolution of international disputes. His current research focuses on the notion of ‘fairness’ in international environmental law and looks at the equitable distribution of environmental costs, risks and responsibilities between the North and the South. He is also conducting research on the ‘figure of the immigrant’ in the European Union, and its construction through legal discourse, structures and processes. His latest book is ‘The Concept of Unity in Public International Law’ (Hart Publishing, 2012).
