Article 19
Freedom of association
(1) Everyone shall have the right to freedom of association
with others, including the right to form and join trade unions for
the protection of his interests.
(2) 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 (ordre public), 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.
(3) Nothing in this article authorizes legislative measures to
be taken which would prejudice, or the law to be applied in such a
manner as to prejudice, the guarantees provided for in the
International Labour Organization Convention of 1948 concerning
Freedom of Association and Protection of the Right to Organize as it
applies to Hong Kong.
