Module summary

Public International Law contains the principles that govern international relations. What are states? When, if ever, can they go to war? How is their sovereignty restricted? When can they be held responsible for international wrongdoing? What is the place of the individual in the global legal order? What happens when these principles are in dispute? These and more questions this module shall address, through engagement not only with doctrinal but also with critical and normative sources.

Module aims

This module aims to enable you to understand and engage critically with the sources and content of public international law, the main critical theories, categories of international rights and obligations, and subjects, institutions and officials of the international legal system.

Relying on innovative approaches to legal teaching and learning, Public International Law will be taught through a combination of the following:

  • Plenaries which will each comprise two hour ‘flipped-classroom’ sessions, during which students will engage primarily in peer-to-peer learning. Either one or both module convenors shall supervise these sessions, answering queries and encouraging group discussion.
  • Companion videos which shall run for approximately 20 minutes each, with the intention of introducing students to the basic concepts to be covered by each plenary, any key terms, and any particularly important points of debate. Individual videos shall be prepared by either one or both module convenors.
  • Seminars which shall each comprise one hour instructor-led discussions, designed to cement the knowledge and understanding gained via the flipped-classroom plenary sessions and companion videos.

Throughout the module, students will have the opportunity to engage with historical and/or contemporary case studies, such as the Russia-Ukraine war.

Upon successful completion of this module, you should be able to:

  • Demonstrate a critical understanding of the sources and content of public international law, the main critical theories, categories of international rights and obligations, and subjects, institutions and officials of the international legal system;

Additional assessment information

In this module, formative assessment will be provided in lectures and seminars through Q&A sessions and 'flipping the classroom' exercises and comments by the lecturer and by fellow students. In addition, during the final week (week 10), the plenary and seminar session shall be dedicated to assessment Q&A.

Two documents specifically designed for this module aim to support students in developing and adapting their learning strategies to the requirements of this module. Part II of the Reading List for this module, provides students with general guidance on public international law research, i.e. how and where to find primary and secondary sources.

Additionally, presentation guidelines will provide detailed guidance on how to prepare the group presentation.
