Nottebohm case ICJ 1 is the proper name for the 1955 case adjudicated by the International Court of Justice. Liechtenstein sought a ruling to force Guatemala to recognize Friedrich Nottebohm as a Liechtenstein national. The case has been cited in many definitions of nationality.
Background
Friedrich Nottebohm was born September 16, 1881, in Hamburg, Germany. In 1905, he moved to Guatemala, where he went into business in trade, banking, and plantations with his brothers. The business prospered, and Nottebohm became its head in 1937. Nottebohm would live in Guatemala until 1943 as a permanent resident without ever acquiring Guatemalan citizenship. He would sometimes visit Germany on business, and had friends and relatives in both countries. He also paid a few visits to Liechtenstein to see his brother Hermann, who had moved there in 1931 and became a citizen. In 1939, Nottebohm again visited Liechtenstein, and on October 9, 1939, shortly after World War II began, he applied for citizenship. His application was approved and he became a citizen. Under German law, he lost his German citizenship. In January 1940, he returned to Guatemala on a Liechtenstein passport and informed the local government of his change of nationality. Although originally neutral, Guatemala soon sided with the Allies and formally declared war on Germany on December 11, 1941. In spite of his Liechtenstein citizenship, the Guatemalan government treated Nottebohm as a German citizen. As part of a massive program in which the US co-operated with various Latin American countries to intern in the US over 4,000 persons of German ancestry or citizenship, Nottebohm was arrested by the Guatemalan government as an enemy alien in 1943, handed over to a US military base, and transferred to the US, where he was interned until 1946. The Guatemalan government confiscated all his property in the country, and the US government also seized his company's assets in the US. In 1950, the US government returned to the Nottebohm family about half the value of what it had seized. The Guatemalan government held on to his property and returned 16 coffee plantations to his family only in 1962, after he had died. After his release, he returned to Liechtenstein, where he lived for the rest of his life. In 1951, the Liechtenstein government, acting on behalf of Nottebohm, brought suit against Guatemala in the InternationalCourt of Justice for what it argued was unjust treatment of him and the illegal confiscation of his property. However, the government of Guatemala argued that Nottebohm did not gain Liechtenstein citizenship for the purposes of international law. The court agreed and so stopped the case from continuing.
Judgment
Although the Court stated that it is the sovereign right of all states to determine its own citizens and criteria for becoming one in municipal law, such a process would have to be internationally scrutinized if the question is of diplomatic protection. The Court upheld the principle of effective nationality : the national must prove a meaningful connection to the state in question. That principle had previously been applied only in cases of dual nationality to determine the nationality that should be used in a given case. The court ruled that Nottebohm's naturalization as a citizen of Liechtenstein had not been based on any genuine link with that country, but for the sole purpose of enabling him to replace his status as the national of a belligerent state with that of a neutral state in a time of war. The Court held that Liechtenstein was not entitled to take up his case and put forward an international claim on his behalf against Guatemala:
Criticism
The ruling came under scrutiny due to the implication that a person could be left without any effective nationality. While applying such a standard in cases of dual nationality would still leave a person eligible for diplomatic protection from one state, Nottebohm was not a citizen of any country other than Liechtenstein at the time, and the ruling implied he may not have been an effective national of any country, though it's unclear if Nottebohm was treated as a dual national due to his long-term residence in Guatemala or previous links to Germany. The International Law Commission noted that in an age of globalization and large-scale migration, this standard has the potential of creating an underclass of millions of people lacking any diplomatic protection, as "there are millions of persons who have drifted away from their state of nationality and made their lives in states whose nationality they never acquire, or have acquired from birth and descent from states with which they have a tenuous connection."
