We decided to start with the obvious – the climate treaties, including the UNFCCC and Paris Agreement as the backbone, with the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC) as the foundation. We reminded that Court that Saint Lucia is a member of COSIS, which had brought a similar request before the Tribunal on the Law of the Sea (ITLOS). We emphasized “systemic integration”: the need for the Court to read the relevant climate treaties together with the UN Charter, UNCLOS, customary law, and human rights, rather than in silos. Coordinating with other participating OECS States (Saint Vincent and the Grenadines and Grenada), we entrusted that responsibility to our OECS Mission in Brussels, led by Chargé d’Affaires Desmond Simon (Saint Lucia) and Ambassador Joseph (Grenada). They worked diligently through the night to prepare hundreds of pages of submissions and annexes, ensuring they were delivered on time.
