(1) Except with his or her own consent, a person shall not be hindered in the enjoyment of his or her freedom of assembly and association, that is to say, his or her right to assemble freely and associate with other persons and in particular to form or belong to trade unions or other associations for the protection of his or her interests or to form or belong to political parties or other political associations.
(2) Nothing contained in or done under the authority of any law shall be held to be inconsistent with or in contravention of this section to the extent that the law in question makes provision—
(a) that is reasonably required in the interests of defence, public safety, public order, public morality or public health;
(b) that is reasonably required for the purpose of protecting the rights or freedoms of other persons; or
© that imposes restrictions upon public officers that are reasonably required for the proper performance of their functions,
and except so far as that provision or, as the case may be, the thing done under the authority thereof is shown not to be reasonably justifiable in a democratic society.
