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 08 19 1356 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJPLIA.010101 https://www.americaspg.com/journal/30/article/1356 https://www.americaspg.com/storage/8641.pdf
