Section 26, The Constitution of Sierra Leone, 1991

(1) Except with his own consent, no person shall be hindered in the enjoyment of his freedom of assembly andassociation, that is to say, his right to assemble freely and associate with other persons and in particular to form or belong to any political party, trade unions or other economic, social or professional associations, national or international, for the protection of his interests. (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. which is reasonably required— i. in the interests of defence, public safety, public order, public morality, public health, or provision for the maintenance of supplies and services essential to the life of the community; or ii. for the purpose of protecting the rights and freedoms of other persons; or b. which imposes restrictions upon public officers and upon members of a defence force; or c. which imposes restrictions on the establishment of political parties, or regulates the organisation, registration, and functioning of political parties and the conduct of its members; and except in 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.
