Decisions of international courts and arbitrators, as well as judgments of national courts, are fundamental elements of modern public international law. The International Law Reports is the only publication in the world wholly devoted to the regular and systematic reporting in English of such decisions. It is therefore an absolutely essential work of reference. Volume 188 is devoted to the Question of the Delimitation of the Continental Shelf between Nicaragua and Colombia beyond 200 Nautical Miles From the Nicaraguan Coast (Nicaragua v. Colombia), The Arctic Sunrise, Khlaifia and Others v. Italy, Whelan v. Ireland, Crimea Annexation Case, European Stability Mechanism Case, Al-Juffali v. Estrada, Ukraine Law v Debenture Trust Corp Plc, Pham v Secretary of State for the Home Department, R (Campaign Against Arms Trade) v Secretary of State for International Trade, Jam and Others v. International Finance Corp., Republic of Sudan v. Harrison and Others
