Public International Law (LL.M.)

Public International Law is a one-year Master’s specialisation at the internationally acclaimed Leiden Law School at Leiden University. The programme focuses on the legal framework that governs international relations in an increasingly complex global society.

Different perspectives

In this programme you will gain a thorough understanding of the fundamental doctrines of public international law, studying different perspectives from theory and practice. We will also challenge you to develop your own views on the role and functioning of law in international society.

Current global challenges

As a result of globalisation and international interdependence, international law is changing. Whereas in the past, this law was limited to relations between states, in recent years, organisations, peoples, business and individuals have also become part of the realm of international law. Who is entitled to intervene in situations of mass violations of human rights? Which means are allowed to combat international terrorism? Can the international community develop governance mechanisms, including law, to deal with problems such as global climate change?

International organisations and courts

This Master’s is taught in Leiden and at Campus The Hague. A unique feature of the programme is that it makes use of the expertise available in the various international institutions located in The Hague, such as the International Court of Justice, the International Criminal Tribunal for Yugoslavia, the International Criminal Court and the Organisation for the Prohibition of Chemical Weapons.
