Dr Wouter Basson, a cardiologist, was charged in 2007 with unprofessional conduct before a professional conduct committee of the Health Professions Council of South Africa (HPCSA) relating to his participation in chemical and biological warfare research during his employment with the South African Defence Force in the 1980s. The committee comprised Professor J F M Hugo (Chairperson), Professor R E Mhlanga, and the late retired Judge Eloff. In December 2013, the committee found Basson guilty on four charges. In January 2015, during sanction hearings, petitions were presented by various medical organizations calling for Basson's removal from the Register of Medical Practitioners. When Basson's counsel inquired whether committee members belonged to these organizations, the committee refused to provide the information. Basson subsequently obtained an interim interdict. Professor Hugo later disclosed he was a member of SAMA and had been associated with RUDASA. In March 2015, Basson applied for the recusal of Professors Hugo and Mhlanga on grounds of bias, which the committee refused. Basson then sought judicial review of this decision.
