ICJ: Authorisation of IUCN & COSIS to participate in Climate Change (AO) proceedings

As previously reported, by Order of 20 April 2023, the ICJ invited states entitled to appear before the ICJ and any international organisations likely to be able to furnish information to submit written statements in respect of Obligations of States in respect of climate change (Request for an Advisory Opinion). It was noted this Order was without prejudice to the possibility of the further addition of participants to the proceedings by authorisation of the ICJ. Pursuant to Article 66 of the ICJ Statute, on 14 June 2023 the ICJ decided that the International Union for Conservation of Nature (IUCN) is likely to be able to furnish information on the questions submitted to the Court by the General Assembly and therefore authorised the IUCN to participate in the proceedings (ICJ Press Release No. 2023/29). Pursuant to Article 66 of the ICJ Statute, on 22 June 2023 the ICJ decided that the Commission of Small Island States on Climate Change (COSIS) is likely to be able to furnish information on the questions submitted to the Court by the General Assembly and therefore authorised the COSIS to participate in the proceedings (ICJ Press Release No. 2023/32).
