Parties to Non-International Armed Conflicts under International Treaty Law

Chapter 2 examines international humanitarian law treaties. Using classical treaty interpretation methods, it establishes what degree of organization is required from a non-state armed group to become ‘Party to the conflict’ under article 3 common to the four Geneva Conventions, or an ‘organized armed group’ under article 1(1) of the Additional Protocol II or under the ICC Statute. Chapter 2 also analyses the travaux préparatoires of the different treaties, subsequent practice, and engages with the main doctrinal debates surrounding these questions. By subjecting the three treaties to thorough analysis, the chapter presents concise interpretations of the relevant organizational requirements, and compares the different thresholds. It also identifies and addresses under-researched questions, such as whether the organization criterion under international humanitarian law requires the capacity to implement the entirety of the applicable law.
