Between Sollen and Sein: The CJEU’s reliance on international law in the interpretation of economic agreements covering occupied territories

Abstract This contribution focuses on the Court of Justice of the European Union (Court or CJEU) reliance on international law in cases involving economic agreements covering occupied territories. In its earlier case law, the Court adopted a formalistic approach by ignoring the broader international legal framework of the dispute in an effort to achieve conformity with international law, while at the same time avoiding being drawn into political storms. The article continues by identifying an even more worrisome trend in the Court’s latest judgments in the Front Polisario and Western Sahara Campaign UK cases. In these two cases the Court showed its willingness to stretch the international rules of treaty interpretation to a breaking point in order to avoid pronouncing on the politically sensitive question of the de facto application of the EU’s agreements with Morocco in the territory of Western Sahara. The article concludes by asserting that the Court’s line of argumentation brings another dimension to the Völkerrechtsfreundlichkeit debate. The classical, binary understanding of the Court’s approach as ‘open/hostile’ to international law only provides us with a partial picture of how international law was actually used in these cases. The Court’s apparent willingness to rely on international law as a heuristic device to reinforce an outcome that radically departs from the logic and structure of international law and international legal argumentation requires a more in-depth engagement with both the content of the international law rules invoked in those judgments and with the Court’s use of such rules.
