With a view to ensuring or promoting the freedom of workers and employers to form local, national or international organisations for the protection of their economic and social interests and to join those organisations, the Contracting Parties undertake that national law shall not be such as to impair nor shall it be so applied as to impair this freedom. The extent to which the guarantees provided for in this article shall apply to the police shall be determined by national laws or regulations. The principle governing the application to the members of the armed forces of these guarantees and the extent to which they shall apply to persons in this category shall equally be determined by national laws or regulations.
