(1) Subject to the provisions of subsections (4) and (5) no law shall make any provision that is discriminatory either of itself or in its effect.
(3) In this section, the expression “discriminatory” means affording different treatment to different persons attributable wholly or mainly to their respective descriptions by race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status 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.
(5) Nothing contained in any law shall be held to be inconsistent with or in contravention of subsection (1) to the extent that it makes provision with respect to standards of qualifications (not being standards of qualifications specifically relating to race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status) to be required of any person who is appointed to any office in the public service, any office in a disciplined force, any office in the service of a local government authority or any office in a body corporate established by law for public purposes.
