Overview of the case
On 9 April 1984 Nicaragua filed an Application instituting proceedings against the United States of America, together with a Request for the indication of provisional measures concerning a dispute relating to responsibility for military and paramilitary activities in and against Nicaragua. On 10 May 1984 the Court made an Order indicating provisional measures. One of these measures required the United States immediately to cease and refrain from any action restricting access to Nicaraguan ports, and, in particular, the laying of mines. The Court also indicated that the right to sovereignty and to political independence possessed by Nicaragua, like any other State, should be fully respected and should not be jeopardized by activities contrary to the principle prohibiting the threat or use of force and to the principle of non-intervention in matters within the domestic jurisdiction of a State. The Court also decided in the aforementioned Order that the proceedings would first be addressed to the questions of the jurisdiction of the Court and of the admissibility of the Nicaraguan Application. Just before the closure of the written proceedings in this phase, El Salvador filed a declaration of intervention in the case under Article 63 of the Statute, requesting permission to claim that the Court lacked jurisdiction to entertain Nicaragua’s Application. In its Order dated 4 October 1984, the Court decided that El Salvador’s declaration of intervention was inadmissible inasmuch as it related to the jurisdictional phase of the proceedings.
After hearing argument from both Parties in the course of public hearings held from 8 to 18 October 1984, on 26 November 1984 the Court delivered a Judgment stating that it possessed jurisdiction to deal with the case and that Nicaragua’s Application was admissible. In particular, it held that the Nicaraguan declaration of 1929 was valid and that Nicaragua was therefore entitled to invoke the United States declaration of 1946 as a basis of the Court’s jurisdiction (Article 36, paragraphs 2 and 5, of the Statute). The subsequent proceedings took place in the absence of the United States, which announced on 18 January 1985 that it “intends not to participate in any further proceedings in connection with this case”. From 12 to 20 September 1985, the Court heard oral argument by Nicaragua and the testimony of the five witnesses it had called. On 27 June 1986, the Court delivered its Judgment on the merits. The findings included a rejection of the justification of collective self‑defence advanced by the United States concerning the military or paramilitary activities in or against Nicaragua, and a statement that the United States had violated the obligations imposed by customary international law not to intervene in the affairs of another State, not to use force against another State, not to infringe the sovereignty of another State, and not to interrupt peaceful maritime commerce. The Court also found that the United States had violated certain obligations arising from a bilateral Treaty of Friendship, Commerce and Navigation of 1956, and that it had committed acts such to deprive that treaty of its object and purpose.
It decided that the United States was under a duty immediately to cease and to refrain from all acts constituting breaches of its legal obligations, and that it must make reparation for all injury caused to Nicaragua by the breaches of obligations under customary international law and the 1956 Treaty, the amount of that reparation to be fixed in subsequent proceedings if the Parties were unable to reach agreement. The Court subsequently fixed, by an Order, time‑limits for the filing of written pleadings by the Parties on the matter of the form and amount of reparation, and the Memorial of Nicaragua was filed on 29 March 1988, while the United States maintained its refusal to take part in the case. In September 1991, Nicaragua informed the Court, inter alia, that it did not wish to continue the proceedings. The United States told the Court that it welcomed the discontinuance and, by an Order of the President dated 26 September 1991, the case was removed from the Court’s List.
