Public International Law

Public International Law is a core specialization within the discipline of International Law, itself part of the broader academic field of Law & Justice. It examines the legal rules, principles, and institutions that govern relations between states and other international actors, including treaties, customary international law, the law of international organizations, state responsibility, jurisdiction and immunities, the law of the sea, diplomatic and consular law, and mechanisms for peaceful dispute settlement. Students learn doctrinal analysis, treaty interpretation, litigation and arbitration strategies before international courts and tribunals (such as the International Court of Justice and arbitral bodies), and advisory practice for states, international organizations, and NGOs.

In an interconnected world, Public International Law underpins governance of transnational challenges: armed conflict and peacebuilding, human rights protection, international trade and investment, migration, transboundary environmental protection and climate law, and accountability for international crimes. Training combines legal research and writing with practical skills, moot courts, negotiation exercises, clinics, and internships at courts, intergovernmental organizations, and civil society bodies, preparing graduates to craft, interpret, and implement rules that shape global cooperation and stability.
