I want to know the answer to the following question:
Who brought litigation to South Africa?
All the background I'm provided with is that "In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent.". Is that enough to answer the question?
Answer: yes
