The 1994 Constitution recognized customary law as being of equal status with common law.
s. 39 (2) When interpreting any legislation, and when developing the common law or customary law, every court, tribunal or forum must promote the spirit, purport and objects of the Bill of Rights.
(3) The Bill of Rights does not deny the existence of any other rights or freedoms that are recognised or conferred by common law, customary law or legislation, to the extent that they are consistent with the Bill.
See Chapter 12 on recognition and role of traditional leaders.
