The charm of maritime delimitation and its enigmatic lessons hardly surprise us, yet the reasoning behind them sometimes seems seductively elusive. On September 23, 2017, a Special Chamber of the International Tribunal for the Law of the Sea (ITLOS) issued its decision in Ghana v. Ivory Coast. The glamour of maritime delimitation is reason enough to note the judgment, but the case also addresses the equidistance principle for maritime delimitation, the standard for the acceptance of a tacit agreement, and international responsibility under Article 83 of the United Nations Convention on the Law of the Sea (UNCLOS).
