ICJ
A6. Public international law of the seaDefinition
International Court of Justice, with maritime cases including North Sea Continental Shelf and Nicaragua v Colombia.
The International Court of Justice, the principal judicial organ of the United Nations seated in The Hague, has decided much of the modern law of maritime delimitation. The North Sea Continental Shelf cases (1969) rejected mandatory equidistance and set out equitable principles; the Gulf of Maine, Libya/Malta, and Nicaragua v Colombia (2012) judgments refined the equidistance/relevant-circumstances method. A state may choose the ICJ as its forum under UNCLOS Article 287, and the Court applies the Convention alongside customary law.
