This online EPRS policy roundtable is dedicated to the European Court of Justice’s landmark ruling in Costa v ENEL (1964). In that decision, the ECJ proclaimed, for the first time, the principle of primacy of EU law, thereby acknowledging the coexistence of national law and Community law and providing for rules of conflict solving between the two legal orders. The event will focus on the origins and context of this landmark case, as well as the current significance of the principle of primacy in the EU legal order. The speakers will include Professor Amedeo Arena from the University of Naples, Professor Sacha Garben from the College of Europe in Bruges, María José Martínez Iglesias, former Director for Legislative Affairs in the Legal Service of the European Parliament, and Rafał Mańko, policy analyst in the Citizens' Policies Unit of the Members' Research Service. The roundtable will be moderated by Micaela Del Monte, head of the Citizens' Policies Unit.

Jutta Schulze-Hollmén, Director for Resources, acting Director for the Members' Research Service, European Parliamentary Research Service (EPRS)

![Financing the European defence industry [Policy Podcast]
Although the European defence industry is generally competitive, more than a decade of underinvestment has kept it from reaching its full potential. The significant under-investment in European defence is demonstrated by the severe difficulties the European defence technological and industrial base (EDTIB) has in obtaining finance. Member States defence budgets will continue to be the EDTIBs main source of funding; however, more collaborative actions and spending would enhance output and efficiency.
