d. human dignity, equity, social justice, equality and non-discrimination;
… (Art. 8)

It is recognised and declared that every person in Zambia has been and shall continue to be entitled to the fundamental rights and freedoms of the individual, that is to say, the right, whatever his race, place of origin, political opinions, colour, creed, sex or marital status, but subject to the limitations contained in this Part³, to each and all of the following, namely:
a. life, liberty, security of the person and the protection of the law;
… (Art. 11)

1. Subject to clauses (4), (5) and (7), no law shall make any provision that is discriminatory either of itself or in its effect.
2. Subject to clauses (6), (7) and (8), no person shall be treated in a discriminatory manner by any person acting by virtue of any written law or in the performance of the functions of any public office or any public authority.
3. In this Article the expression “discriminatory” means affording different treatment to different persons attributable, wholly or mainly to their respective descriptions by race, tribe, sex, place of origin, marital status, political opinions, colour or creed whereby persons of one such description are subjected to disabilities or restrictions to which persons of another such description are not made subject or are accorded privileges or advantages which are not accorded to persons of another such description.
4. Clause (1) shall not apply to any law so far as that law makes provision-
…
c. with respect to adoption, marriage, divorce, burial, devolution of property on death or other matters of personal law;
d. for the application in the case of members of a particular race or tribe, of customary law with respect to any matter to the exclusion of any law with respect to that matter which is applicable in the case of other persons; or
e. whereby persons of any such description as is mentioned in clause (3) may be subjected to any disability or restriction or may be accorded any privilege or advantage which, having regard to its nature and to special circumstances pertaining to those persons or to persons of any other such description is reasonably justifiable in a democratic society.
5. Nothing contained in any law shall be held to be inconsistent with or in contravention of clause (1) to the extent that it is shown that it makes reasonable provision with respect to qualifications for service as a public officer or as a member of a disciplined force or for the service of a local government authority or a body corporate established directly by any law.
6. Clause (2) shall not apply to anything which is expressly or by necessary implication authorised to be done by any such provision or law as is referred to in clause (4) or (5).
7. Nothing contained in or done under the authority of any law shall be held to be inconsistent with or in contravention of this Article to the extent that it is shown that the law in question makes provision whereby persons of any such description as is mentioned in clause (3) may be subjected to any restriction on the rights and freedoms guaranteed by Articles 17, 19, 20, 21 and 22, being such a restriction as is authorised by clause (2) of Article 17, clause (5) of Article 19, clause (2) of Article 20, clause (2) of Article 21 or clause (3) of Article 22, as the case may be.
8. Nothing in clause (2) shall affect any discretion relating to the institution, conduct or discontinuance of civil or criminal proceedings in any court that is vested in any person by or under this Constitution or any other law. (Art. 23)
