Article 4 State of nationality of a natural person For the purposes of the diplomatic protection of a natural person, a State of nationality means a State whose nationality that person has acquired, in accordance with the law of that State, by birth, descent, naturalization, succession of States or in any other manner, not inconsistent with international law.

Article 5 Continuous nationality of a natural person 1. A State is entitled to exercise diplomatic protection in respect of a person who was a national of that State continuously from the date of injury to the date of the official presentation of the claim. Continuity is presumed if that nationality existed at both these dates. 2. Notwithstanding paragraph 1, a State may exercise diplomatic protection in respect of a person who is its national at the date of the official presentation of the claim but was not a national at the date of injury, provided that the person had the nationality of a predecessor State or lost his or her previous nationality and acquired, for a reason unrelated to the bringing of the claim, the nationality of the former State in a manner not inconsistent with international law. 3. Diplomatic protection shall not be exercised by the present State of nationality in respect of a person against a former State of nationality of that person for an injury caused when that person was a national of the former State of nationality and not of the present State of nationality.
