European Convention on Nationality

It is a comprehensive convention of the Council of Europe dealing with the law of nationality.

Article 5 provides that no discrimination shall exist in a state's internal nationality law on the grounds of "sex, religion, race, colour or national or ethnic origin".

It provides for nationality to be acquired at birth by descent from either parent to those born within the territory of the state.

(States may exclude partially or fully children born abroad).

Finally, it provides loss of nationality for "conduct seriously prejudicial to the vital interests of the State Party".
