It is assumed that all students already have a good working knowledge of public international law. On this assumption, the purpose of this course is two-fold: first, to refresh knowledge of the main chapters of public international law, its general principles and key doctrines; secondly, to focus attention upon recent developments and topical issues affecting these general principles. Themes discussed are: the history and function of international law, sources, statehood, territorial and maritime delimitation, international responsibility, treatment of aliens, jurisdiction and immunities, human rights and IHL, UN system and targeted sanctions, use of force and international terrorism and fragmentation and the proliferation of international courts.
