Right to freedom from discrimination
Section 42(3) · 1999 Constitution (2004 edition)
What Constitution says
(3) Nothing in subsection (1) of this section shall invalidate any law by reason only that the law imposes restrictions with respect to the appointment of any person to any office under the State or as a member of the armed forces of the Federation or member of the Nigeria Police Forces or to an office in the service of a body, corporate established directly by any law in force in Nigeria.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
