The Committee of Experts on Nationality (CJ-NA) was responsible for the inter-governmental co-operation in the field of nationality. The Committee consisted of officials with a practical knowledge of citizenship issues from each member state of the Council of Europe as well as observers from a number of other States and international organisations.

The main aims of the Committee were:
- to follow developments on nationality issues, in particular in member states of the Council of Europe;
- to search for solutions aiming at the harmonisation of rules and practices in Europe on matters concerning acquisition and loss of nationality;
- to hold regular exchanges of view to achieve a common standing between member States, and to make proposals for the solution of practical and legal problems faced by States within its field of competence, namely by drafting legal instruments (conventions and recommendations) for adoption by the Committee of Ministers.
