About this lecture

Self-determination is a concept that has attracted much discussion at the theoretical and practical levels. Questions concerning its legal scope, the holder of the right and its content have been controversial. On 25 February 2019. the International Court of Justice rendered an advisory opinion on the Legal Consequences of the Separation of the Chagos Archipelago from Mauritius in 1965 that shed light on these issues in a mnner that goes beyond the particulardispute the impact of this advisory opinion in the interpretation and application of this fundamental principle of general international law.
