The UDHR at 75: Analysing the Prevalence of the Use of the UDHR and Other Human Rights Treaties in the Work of the Constitutional Court of South Africa

South Africa’s democracy turned 30 years old in 2024. At the same time, its constitutional order and jurisprudence marked three decades since the Interim Constitution and its successor, the 1996 Constitution, came into operation. Coincidentally, the Universal Declaration of Human Rights (UDHR) turned 75 years old in the previous year, 2023. The confluence of these facts is quite poignant in the context of a constitutional text that is often lauded for its commitment to the protection of human rights and the eradication of the injustices of the past, which were firmly entrenched by the segregationist policies of the apartheid regime. At the centre of this hype about South African constitutional jurisprudence is the centrality of international law to the interpretation of the Bill of Rights as well as the development of the common law, customary law, and statutory law. With the UDHR being such a central pillar in the human rights sector, this study set out to determine the extent to which the Constitutional Court of South Africa relied on the UDHR and other international instruments in carrying out the mandate set out above. The study analysed cases delivered by the Court in two separate years, spaced ten years apart. The study did not necessarily attempt to determine a correlation, but simply to use descriptive statistics to determine how often, in those two years, the Court relied on international law in general, and on the UDHR in particular, in its interpretive and legal development mandate.
