In its judgment in the Basson II case in 2005, the Constitutional Court of South Africa stated:
[179] … There can be no doubt that the use of instruments of state to murder captives long after resistance had ceased would in the 1980s, as before and after, have grossly transgressed even the most minimal standards of international humanitarian law.
[180] The same has to be said of … the provision of cholera bacteria for placement in water supplies. Such means of warfare are abhorrent to humanity and forbidden by international law. … In 1925 the Geneva Protocol prohibited the use of chemical and bacteriological weapons. In 1972 the ban on bacteriological means of warfare was restated and strengthened by a specific convention designed to prohibit the manufacture and stockpiling of these agents of destruction.
