Case Digest: Nicaragua v. U.S., ICJ 1984
Public International Law | Jurisdiction of the ICJ: Contentious jurisdiction
Facts:
- In 1946, the U.S. made an Optional Clause Declaration with a reservation allowing termination after five years plus six months' notice.
- In 1984, when it became clear that its dispute with Nicaragua would be placed before the Court, the U.S. deposited a notification restricting its 1946 declaration's applicability to disputes involving Central American states or events in Central America for two years.
- Nicaragua sought to rely on the 1946 U.S. declaration to establish the ICJ's jurisdiction, claiming it was a state accepting the same obligation as the U.S. under Article 36, paragraph 2, of the Statute.
Held:
- The Court found Nicaragua that it was a state accepting the same obligation but on the basis of a declaration it made under the Statute of the Permanent Court of International Justice.
- The Court therefore finds that the Nicaraguan declaration of 1929 is valid and that Nicaragua accordingly was, for the purposes of Article 36, paragraph 2, of the Statute of the Court, a “State accepting the same obligation” as the United States at the date of filing of the Application and could therefore rely on the United States declaration of 1946.
- The declaration of the United States: The notification of 1984
- The acceptance of the jurisdiction of the Court by the United States on which Nicaragua relies is the result of the United States declaration of 14 August 1946.
- However, the United States argues that effect should be given to the letter sent to the Secretary- General of the United Nations on 6 April 1984.
- It is clear that if this notification were valid as against Nicaragua at the date of filing of the Application, the Court would not have jurisdiction under Article 36 of the Statute.
- After outlining the arguments of the Parties in this connection, the Court points out that the most important question relating to the effect of the 1984 notification is whether the United States was free to disregard the six months’ notice clause which, freely and by its own choice, it has appended to its declaration, in spite of the obligation it has entered into vis-a-vis other States which have made such a declaration.
- The Court notes that the United States has argued that the Nicaraguan declaration, being of undefined duration, is liable to immediate termination, and that Nicaragua has not accepted “the same obligation” as itself and may not rely on the time-limit proviso against it.
- The Court does not consider that this argument entitles the United States validly to derogate from the time-limit proviso included in its 1946 declaration.
- In the Court’s opinion, the notion of reciprocity is concerned with the scope and substance of the commitments entered into, including reservations, and not with the formal conditions of their creation, duration or extinction.
- Reciprocity cannot be invoked in order to excuse departure from the terms of a State’s own declaration. The United States cannot rely on reciprocity since the Nicaraguan declaration contains no express restriction at all.
- On the contrary, Nicaragua can invoke the six months’ notice against it, not on the basis of reciprocity, but because it is an undertaking which is an integral part of the instrument that contains it.
- The 1984 notification cannot therefore override the obligation of the United States to submit to the jurisdiction of the Court vis-a-vis Nicaragua.
