A multitude of actors at the national and supranational level typically have a stake in the EU’s relationship with third countries. Governmental and non-governmental actors seek to frame debates over the EU’s external relations in ways that suit their own interests. In their article “Legal framing and the EU’s external relations: how NGOs shaped the negotiations for an Israel-Europol cooperation agreement” published in the Journal of European Public Policy, Patrick Müller and Peter Slominski highlight that a recourse to legal arguments can give actors with limited power resources the upper hand in shaping the EU’s foreign policy. Patrick and Peter argue that strategies of legal framing, encompassing intimate knowledge of and an ability to align arguments with the laws regulating conduct in a legal community, allow non-governmental organizations to leave their mark on the EU’s external relations. Their analysis of the negotiations on the Israel-Europol agreement shows that an EU-registered civil society organization, the MATTIN Group, employed various strategies of legal framing, highlighting that a draft text of the agreement would have been inconsistent with the EU’s legal position, and ultimately convincing EU officials to include additional conditions in their negotiations with their Israeli counterparts. The evidence presented by Patrick and Peter illustrates that by connecting its legal reasoning with a stable understanding of the law within the EU, the MATTIN Group managed “to develop a powerful legal frame, which finally prevailed in the intra-EU debate despite a strong political interest to reach an agreement.”
