After South Africa gained independence from apartheid, its economic and industrial growth started happening in the true sense.
In South Africa, the industries for the generation of electricity(Eskom), for civil aviation (South African Express Airways), for diamond mining (Alexkor), for the production of weapons and artillery (Denel), for railways (Transnet), etc. are owned by the government.
Whereas, production and service industries other than the disciplines above are mostly owned by private players. This makes South Africa a mixed economy.
When the party that lost a court case asks for a higher court to review the decision, that person is using the right to "appeal," since cases can go all the way up to the Supreme Court.
