In June 1991, the Population Registration Act, 1950, a cornerstone of apartheid legislation, was repealed by the government of F. W. de Klerk, and in July an INOCSA delegation met with the Apartheid and Olympism Commission at the IOC headquarters in Lausanne. The IOC recognised INOCSA on 9 July 1991, such that the "interim" was removed from its name (NOCSA). It first competed at the 1992 Summer Olympics in Barcelona. The official flag of South Africa and national anthem "Die Stem van Suid-Afrika" were still the apartheid-era ones, but the Olympic team competed under an interim flag and Beethoven's "Ode to Joy". Likewise it decided not to use the Springbok emblem or green-and-gold colours of white sports teams. These decisions were unpopular with white South Africans, and as a concession the green-and-gold colours were adopted. NOCSA in 2004 merged with other bodies to form the South African Sports Confederation and Olympic Committee (SASCOC).
