The Institute for Security Studies (ISS), a research organisation focused on human security and international criminal law, sought admission as amicus curiae in criminal appeal proceedings before the Constitutional Court involving Dr Wouter Basson. The State consented to the ISS’s admission, but Dr Basson opposed it. The ISS wished to make submissions on international crimes, including crimes against humanity, conspiracy charges, extradition, amnesties, and South Africa’s international obligations. After hearing argument, the Constitutional Court refused the application and later provided reasons for that refusal.
