The (TAC) was founded in December 1998 to campaign for access to treatment for HIV/AIDS. It is widely acknowledged as one of the most important civil society organisations active on AIDS in the developing world. One of its most significant victories was the 2002 Constitutional Court ruling in which the South African government was ordered to provide anti-retroviral drugs to prevent transmission of HIV from mothers to babies during birth. In the years following TAC's campaigns were instrumental in securing a universal government-provided AIDS treatment programme, which has since become the world's largest. In 2007, in large part owing to pressure from the TAC, the National Strategic Plan on HIV, STIs and Tuberculosis 2007-2011 was adopted by Parliament. Today the TAC continues to represent users of the public healthcare system in South Africa, and to campaign and litigate on critical issues related to healthcare. The organisation currently has over 8 000 members and a network of 182 branches and provincial offices in seven of South Africa's nine provinces. The TAC monitors thousands of clinics and hospitals.
