International Journal of Private Law and International Arbitration IJPLIA 2836-5216 10.54216/IJPLIA https://www.americaspg.com/journals/show/1356 2022 2022 American University in the Emirates, Dubai, UAE Mahir Al Banna The legal status of the Chagos archipelago is complex because it is of a hybrid nature: it is under the sovereignty of the United Kingdom which grants rights at sea to Mauritius, and on land to the United States (Diego Garcia). This case is also important because it is not easy to have two divergent preoccupations: the protection of the environment in the face of the rights of Chagossians and environmental sustainability in the face of equity and human rights. This case was first submitted to the Permanent Court of Arbitration (PCA), before the UN General Assembly had asked the International Court of Justice (ICJ) about the claims that the PCA declared it lacked jurisdiction to answer. 2022 2022 08 19 10.54216/IJPLIA.010101 https://www.americaspg.com/articleinfo/30/show/1356
