The International Court of Justice (ICJ), was seised of a dispute between Guatemala and Belize by way of a special agreement. In 2008, the two States concluded an agreement to submit Guatemala’s territorial, insular and maritime claim to the International Court of Justice, which was subsequently amended by a protocol concluded in 2015. The Parties now request the Court to determine in accordance with applicable rules of international law as specified in Article 38(1) of the Statute of the Court any and all legal claims of Guatemala against Belize to land and insular territories and to any maritime areas pertaining to these territories, to declare the rights therein of both Parties, and to determine the boundaries between their respective territories and areas.
More information on the case and the referenda that led to it can be found in the ICJ press release, at the Belize Referendum Commission website and in a presentation held by the Ministry of Foreign Affairs of Guatemala (in Spanish).
