LLM / Department of Mercantile Law / Scholarship on the subject of Corporate Social Responsibility (CSR) highlights its four components: economic, legal, ethical and philanthropic responsibility. In South Africa, while the economic, legal and ethical components of CSR are regulated and attract punitive measures for erring corporations who fail to adhere to such demands, the application of the philanthropic aspect of CSR is problematic. The application of philanthropic responsibility suffers normative, institutional and accountability deficiencies in South Africa. Hence, corporations do not conscientiously direct philanthropic responsibility towards achieving core socio-economic needs of their host communities. In the light of international human rights standards relevant to CSR, this research attempts to examine domestic laws which regulate the practice of CSR in South Africa and advance how the philanthropic aspect of CSR can be developed to achieve the realisation of socio-economic rights, in particular, the rights to access to health care, water and social security, education, housing and clean environment. The argument is made that through the formulation and application of an appropriate legal framework, philanthropic CSR can play a contributory role to the realisation of socio-economic rights recognised under the 1996 South African constitution. The implications are that in appropriate cases socio-economic rights do not only bind the state and consequently apply to the "vertical" relationship between individuals and the state, but could also apply "horizontally", in respect of the relationship between private entities. This is a controversial issue and its full implications have not yet been resolved.
