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

The apartheid-era South African constitution, which was in effect from 1948 to 1994, embraced a system of complete denial of the principle of constitutionalism. This constitution institutionalized racial segregation and discrimination, denying basic rights and freedoms to the majority of the population based on their race. It was a fundamentally unjust and oppressive legal framework that was eventually dismantled with the end of apartheid.
