Nationality is the legal bond between an individual and a State, entailing reciprocal rights and duties and enabling the State to exercise diplomatic protection. Nationality is within domestic jurisdiction (Nationality Decrees in Tunis and Morocco, PCIJ 1923), but international law limits its effects. Hague Convention 1930, Art 1: each State determines under its own law who are its nationals; other States recognise this only if consistent with international conventions, custom and generally recognised principles.
Nottebohm Case (Liechtenstein v Guatemala, ICJ 1955): Nottebohm, a German national, naturalised in Liechtenstein shortly before WWII. ICJ held nationality must rest on a ‘genuine link’ (a real connection of existence, interests and sentiments); Guatemala was not obliged to recognise Liechtenstein’s claim. The test is applied mainly to diplomatic protection, not nationality per se.
