External action and self-determination: the coherence of EU external action with the principles of customary international law in the light of the Western Sahara Campaign

      Comments Off on External action and self-determination: the coherence of EU external action with the principles of customary international law in the light of the Western Sahara Campaign

The paper represents a continuation of my research on the relationship between European Union external action and international law, published last year on the European Foreign Affairs Review. The aim is to investigate on the coherence of European Union External Action with the principles of public international law and particularly with the protection of the right to self-determination. The case Western Sahara Campaign case opened a Pandora Box on the role of the European Union as international actor. The Court underlined the necessity of interpreting international agreements concluded by the EU with respect to the rules of customary international law and the right to self-determination of people. In the light of the Court’s findings should the EU give priorities to its commercial interests or should prevail the protection of oppressed groups such as the Saharawi people? The Court did not explicitly refer just to UN Charter Article 73, but also to Article 1 which recognizes the right of self-determination to all people. Such a situation could expose EU external trade policies to claims by every group which affirms its right to self-determination. The aim of the paper is to show that the judgment of the Court should have been more pragmatic, specifying within which limits self-determination claims should be taken into account by EU external actions.
