Freedom of association

1. Everyone has the right to freedom of peaceful assembly and association with others, including the right to form trade unions for the protection of one's interests.
2. No one may be compelled to belong to an association.
3. No restrictions may be placed on the exercise of this right other than those which are prescribed by law and which are necessary in a democratic society in the interests of national security or public safety, public order, the protection of public health or morals or the protection of the rights and freedoms of others. This article shall not prevent the imposition of lawful restrictions on members of the armed forces and of the police in their exercise of this right.
