(3) In this section, the expression “discriminatory” means affording different treatment to different persons attributable wholly or mainly to their respective descriptions by race, place of origin, political opinions, colour, creed or sex 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) of this section to the extent that it makes provision with respect to standards or qualifications (not being standards or qualifications specifically relating to race, place of origin, political opinions, colour, creed or sex) to be required of any person who is appointed to or to act in any office in the public service. Any office in a disciplined force, any office in the service of a local government authority or in any office in a body corporate established by law for public purposes.
