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 204 is devoted to Somalia v. Kenya, Situation in the State of Palestine, The M/T 'San Padre Pio' Case (Switzerland v. Nigeria) and Ukraine v. Russian Federation.
