Center for European and International Law

Organisational unit: Institute

Organisation profile

The directors of the Leuphana Center for European and International Law (CEIL) conduct research on fundamental issues of European and international law. The research focuses on questions of securing constitutional structures based on the rule of law at the European and international level as well as on fundamental questions of legitimacy and structure of European and international economic law. Another focus is on European and international sustainability law as well as on dispute resolution at the European and international level.

In the Center for European and International Law, scholars from the School of Sustainability (Prof. Dr. Jelena Bäumler & Prof. Dr. Valentin Schatz) and the School of Public Affairs (Prof. Dr. Till Patrik Holterhus, Prof. Dr. Suzan Denise Hüttemann, Prof. Dr. Christian J. Tams, Prof. Dr. Jörg Philipp Terhechte) conduct joint research.

Main research areas

Listed below are publications that exemplify the work produced by the members of CEIL. A comprehensive list of publications by the members of the Centre can be found on the websites of the respective individuals and via the research database FOX of the Leuphana University of Lüneburg.

European Law

In the area of European law, the research focuses on Union constitutional and administrative law, cooperation in criminal law and EU economic law. Here, fundamental questions of the constitutionality of the EU are dealt with as well as current questions of economic law, whereby the connection to sustainability law and the role of the EU as a global actor are of particular importance.

International Law

Research on international law covers the central areas of the law of the international community. This includes questions of international maritime law, global environmental law and legal aid law as well as the foundations of the international legal order (state responsibility, sources of law). The academic work in these fields is application-oriented; it benefits from close cooperation with legal practitioners in governments, international organisations, NGOs and the legal profession.

International Business Law

In the field of international economic law, the focus is on research projects on WTO law and investment protection law. The directors of CEIL have a wide range of experience in the practical examination of the respective topics and have assumed numerous functions in international legal disputes in this context.

European and International Sustainability Law

Research on European and international sustainability law examines the individual legal levels and their interaction from the perspective of sustainability. Based on the UN Sustainable Development Goals and the European Green Deal, the role and transformation potential of law for central challenges of the present, such as climate change, biodiversity loss or environmental pollution, are examined.

Dispute Resolution

The peaceful settlement of international conflicts is the focus of many of CEIL's research projects. In close cooperation with international institutions (international tribunals, arbitration courts), the diverse regimes of international dispute resolution are researched. In addition to their academic work, directors of CEIL regularly participate in international (arbitration) court proceedings, for example as experts or legal advisors.
