In the South African constitution, the beginning of Chapter 1 reads:
The Republic of South Africa is one, sovereign, democratic state founded on the following values:
(a) Human dignity, the achievement of equality and the advancement of human rights and freedoms.
(b) Non-racialism and non-sexism.
(c) Supremacy of the constitution and the rule of law.
(d) Universal adult suffrage, a national common voters roll, regular elections and a multi-party system of democratic government, to ensure accountability, responsiveness and openness.
What is the understood meaning of "equality" in the bold phrase? Has this ever been tested in court?
