South Africa has ratified the ICESCR and in terms of section 231(4) of the Constitution is required to enact legislation to implement the International Convention on Economic, Social and Cultural Rights (ICESCR). Chapter 2 of South Africa’s Constitution is based on the ICESCR which promotes and protects socio-economic and cultural rights. Socio-economic and cultural rights are also promoted in myriad pieces of legislation which give effect to the obligation contained in the Constitution (towards socio-economic and cultural rights). There is therefore no additional legislation required to implement the tenets of the ICESCR.
South Africa is yet to ratify the Optional Protocol to the ICESCR, so no obligation to enact legislation to domesticate the option protocol exists. Once the Optional Protocol is ratified section 231 (4) of the Constitution requires that the treaty be domesticated through the enactment of national legislation.
