In her ruling, Khampepe said the applications were brought after unreasonable delays and were not supported by adequate explanations. The ruling means both Mbeki and Zuma will be required to testify before Khampepe at the commission of inquiry. Khampepe has given three reasons for her decision to dismiss the recusal applications by the former presidents.
