[Part I of a two-part post]
The advisory proceedings concerning the Legal Consequences of the Separation of the Chagos Archipelago from Mauritius in 1965 are over, but an opinion that answers the legal questions raised in the request could have consequences well beyond the Indian Ocean.
Earlier this month, Stephen Allen contributed a post on the self-determination arguments made in relation to the first question asked of the court. Like Allen, I have taken sides in my scholarly work, although unlike Allen, I have argued that self-determination emerged as a customary norm of international law before 1970. As I argued in my article on the arbitration (2010-2015) between the UK and Mauritius (published in volume 19 of The Max Planck Yearbook of United Nations Law, 2016, pp. 419-468), the emergence of a norm prohibiting partition in the decolonization context would have outlawed the division of the archipelago before independence in 1968, unless it could be shown that Mauritius consented to the separation.
In this post, I argue that the legal arguments raised by the Applicants in the South West Africa Cases could be of direct relevance to the opinion, because although the ICJ refused to address the merits, the cases spanned a period of time (1960-1966) that is germane to any contemporary assessment of the legality of the decision to partition the Chagos Archipelago in 1965. While the Applicants did not reference the Colonial Declaration (GAR 1514 (XV) (1960) in their pleadings, they nevertheless argued that international law in the 1960s prohibited partition, demonstrating that there were principles of law at stake that proscribed the non-consensual division of territory.
What remains missing is an authoritative opinion from the world court. Read the rest of this entry…
