Which south African constitution that embraced an approach of complete denial of the principle of constitutionalism?

The South African constitution that embraced an approach of complete denial of the principle of constitutionalism was the apartheid-era constitution, which was in effect from 1948 to 1994. This constitution entrenched and institutionalized racial segregation and discrimination, and denied basic rights and freedoms to the majority of the population based on their race. It was fundamentally at odds with the principles of constitutionalism, which emphasize the rule of law, equality before the law, and the protection of individual rights and freedoms.
