Courses

Global Security and Peaceful Dispute Settlement in International Law
Valentin Schatz, Christian Tams
This course focuses on the relationship between global security issues
and the peaceful settlement of disputes in international law (PDS).
First, it provides an overview and understanding of the methods of PDS, which range from negotiation to the use of international institutions to recourse to binding forms of settlement such as judicial or arbitral proceedings.
Second, this course explores how PDS relates to diverse global security issues in the 21th century, while employing a broad understanding of ‘global security’ that emphasizes interlinkages between security and global challenges such as environmental protection, human rights and migration.

Security, Power and Law in the 21st Century
Jelena Bäumler, Valentin Schatz, Angar Verma
This lecture series explores the relationship between international law, security, and power in the 21st century. As states increasingly perceive a wide range of developments as security challenges, and as geopolitical power relations continue to evolve, the triangular relationship between international law, security, and power calls for its rethinking. To this end, the lecture series examines, across different fields of international law, how changing understandings of security and shifting power relations shape the development and application of international law; it also explores how international law influences – and can influence – security and power.

Bringing together scholars and practitioners, the lecture series covers topics including collective and regional peace and security, peacemaking, maritime security, international criminal accountability, international trade and investment, counter-terrorism, and environmental security.

Sustainable Ocean Law and Governance
Valentin Schatz
This seminar addresses the role, achievements and shortcomings of international law and relevant global and regional actors and institutions in achieving sustainable ocean governance. Its main focus is on the international legal framework governing the sustainable use and protection of the oceans and the international institutions established for the purpose of, or involved in, implementing these legal frameworks (for example, the International Maritime Organization (IMO), the International Seabed Authority (ISA) or regional fisheries management organizations (RFMOs)). In the media, we regularly read about the shortcomings of this legal and institutional order (such as the ongoing ‘tragedy of the commons’), with journalists writing bestselling accounts of the oceans as a “lawless frontier” and filmmakers reaching broad audiences with documentaries such as the rather activist ‘Seaspiracy’ or the more impressive ‘Ocean with David Attenborough’. Against that backdrop, this seminar aims not only to foster an understanding of ocean governance as an integrative concept – i.e., drawing from a broad legal framework – but also to diagnose the reasons for its shortfalls. Specifically, we will focus on environmental sustainability rather than all facets of what ‘sustainable’ ocean governance may entail (e.g., social sustainability, such as human rights, etc.). In essence, we will consider the legal and institutional dimension of UN Sustainable Development Goal 14 (“Life below Water”), which encourages us to “[c]onserve and sustainably use the oceans, seas and marine resources for sustainable development”. Where suitable, the seminar will also draw on security-related debates concerning ocean sustainability, such as in the context of illegal, unreported and unregulated (IUU) fishing. The global order of the oceans is uniquely suitable for the study of governance challenges due to its unmatched plurality of differing legal spaces (areas of full State sovereignty such as the internal waters, ‘free access’ global commons such as the high seas, internationally managed global commons such as the deep seabed beyond national jurisdiction, and various spaces in between) and an unprecedented number of international organizations and bodies with a law-making competence.

The seminar begins by providing a general introduction to the main pillars and tenets of the global order of the oceans (particularly the 1982 United Nations Convention on the Law of the Sea (UNCLOS) as well as the concepts of ocean governance and ocean sustainability. Thereafter, the seminar analyzes specific persistent and/or contemporary challenges and recent or ongoing developments with respect to sustainable ocean governance. These topical sessions and the examples and/or case-studies examined in them highlight the importance not only of international law and institutions but also of its implementation through the prescription and enforcement of regional (for example, European) and domestic (for example, German) law.
