The member States of the Council of Europe and the other States signatory to this Convention,
Considering that the avoidance of statelessness is one of the main concerns of the international community in the field of nationality;
Noting that State succession remains a major source of cases of statelessness;
Recognising that the European Convention on Nationality (ETS No. 166), opened for signature in Strasbourg on 6 November 1997, contains only general principles and not specific rules on nationality in case of State succession;
Bearing in mind that, with regard to statelessness in relation to State succession, other international instruments either do not have a binding character or do not address some important issues;
Convinced that for the reasons above there is a need for a comprehensive international instrument on State succession and the avoidance of statelessness which should be interpreted and applied, bearing in mind the principles of the European Convention on Nationality;
Taking into account Recommendation No. R (99) 18 of the Committee of Ministers on the Avoidance and Reduction of Statelessness, as well as the practical experience gained in recent years with regard to State succession and statelessness;
Having regard to other binding international instruments, namely the United Nations Conventions relating to the Status of Stateless Persons and on the Reduction of Statelessness, and the Vienna Conventions on Succession of States in respect of Treaties and on Succession of States in respect of State Property, Archives and Debts;
Having also regard to the draft articles on nationality of natural persons in relation to the succession of States, prepared by the United Nations International Law Commission, contained in the Annex to the United Nations General Assembly Resolution 55/153 of 2001 as well as the Declaration of the European Commission for Democracy through Law (Venice Commission) on the Consequences of State Succession for the Nationality of Natural Persons;
Building upon, but without prejudice to, the general principles established in the international instruments and documents mentioned above, by adding specific rules applicable to the particular situation of statelessness in relation to State succession;
In order to give effect to the principles established in the European Convention on Nationality that everyone has the right to a nationality and that the rule of law and human rights, including the prohibition of arbitrary deprivation of nationality and the principle of non-discrimination, must be respected in order to avoid statelessness,
Have agreed as follows:
Article 1 Definitions
For the purposes of this Convention :
a. “State succession” means the replacement of one State by another in the responsibility for the international relations of territory;
b. “State concerned” means the predecessor State or the successor State, as the case may be;
c. “Statelessness” means the situation where a person is not considered as a national by any State under the operation of its internal law;
d. “Habitual residence” means a stable factual residence;
e. “Person concerned” means every individual who, at the time of the State succession, had the nationality of the predecessor State and who has or would become stateless as a result of the State succession.
Article 2 Right to a nationality
Everyone who, at the time of the State succession, had the nationality of the predecessor State and who has or would become stateless as a result of the State succession has the right to the nationality of a State concerned, in accordance with the following articles.
Article 3 Prevention of statelessness
The State concerned shall take all appropriate measures to prevent persons who, at the time of the State succession, had the nationality of the predecessor State, from becoming stateless as a result of the succession.
Article 4 Non-discrimination
When applying this Convention, States concerned shall not discriminate against any person concerned on any ground such as sex, race, colour, language, religion, political or other opinion, national or social origin, association with a national minority, property, birth or other status.
Article 5 Responsibility of the successor State
1. A successor State shall grant its nationality to persons who, at the time of the State succession, had the nationality of the predecessor State, and who have or would become stateless as a result of the State succession if at that time:
a. they were habitually resident in the territory which has become territory of the successor State, or
b. they were not habitually resident in any State concerned but had an appropriate connection with the successor State.
2. For the purpose of paragraph 1, sub-paragraph b, an appropriate connection includes inter alia:
a. a legal bond to a territorial unit of a predecessor State which has become territory of the successor State;
b. birth on the territory which has become territory of the successor State;
c. last habitual residence on the territory of the predecessor State which has become territory of the successor State.
Article 6 Responsibility of the predecessor State
A predecessor State shall not withdraw its nationality from its nationals who have not acquired the nationality of a successor State and who would otherwise become stateless as a result of the State succession.
Article 7 Respect for the expressed will of the person concerned
A successor State shall not refuse to grant its nationality under Article 5 paragraph 1, sub-paragraph b, where such nationality reflects the expressed will of the person concerned, on the grounds that such a person can acquire the nationality of another State concerned on the basis of an appropriate connection with that State.
Article 8 Rules of proof
1. A successor State shall not insist on its standard requirements of proof necessary for the granting of its nationality in the case of persons who have or would become stateless as a result of State succession and where it is not reasonable for such persons to meet the standard requirements.
2. A successor State shall not require proof of non-acquisition of another nationality before granting its nationality to persons who were habitually resident on its territory at the time of the State succession and who have or would become stateless as a result of the State succession
Article 9 Facilitating the acquisition of nationality by stateless persons
A State concerned shall facilitate the acquisition of its nationality by persons lawfully and habitually residing on its territory who, despite Articles 5 and 6, are stateless as a result of the State succession.
Article 10 Avoiding statelessness at birth
A State concerned shall grant its nationality at birth to a child born following State succession on its territory to a parent who, at the time of State succession, had the nationality of the predecessor State if that child would otherwise be stateless.
Article 11 Information to persons concerned
States concerned shall take all necessary steps to ensure that persons concerned have sufficient information about rules and procedures with regard to the acquisition of their nationality.
Article 12 Procedural guarantees
When applying this Convention, the State concerned shall ensure that in the framework of the procedures relating to nationality :
a. the relevant applications be processed within a reasonable time;
b. the relevant decisions contain reasons in writing and be open to an administrative or judicial review in conformity with its internal law;
c. the fees be reasonable and not an obstacle for applicants.
Article 13 Settlement by international agreement
States concerned shall endeavour to regulate matters relating to nationality, especially with a view to avoiding statelessness, where appropriate by international agreement.
Article 14 International co-operation
1. In order to adopt appropriate measures to avoid statelessness arising from State succession, States concerned shall co-operate among themselves, including by providing information with regard to the operation of their relevant internal law.
2. For the same purpose as that mentioned in paragraph 1, States concerned shall also co-operate:

3. If several States concerned make a declaration, as set out in paragraph 2, in respect of the same State succession, this Convention will apply between the States making such declaration.
