The former apartheid-era chemical warfare, Dr Wouter Basson is expected to appeal against the Health Professional Council of South Africa (HPCSA) ruling in the Supreme Court of Appeal in Bloemfontein.

Basson was found guilty of unethical behaviour while working on the apartheid government weapons programme in the 1980s and early 1990s.

Basson has taken the council (HPCSA) and two members to court for being biased against him.

He wants Professors Eddie Mhlanga and Jannie Hugo to be recused. The professors have refused to recuse themselves.

Basson was found guilty of unprofessional conduct by the Health Professions Council of SA in December 2013, following a six-year long inquiry.

The HPCSA inquiry was held to determine whether Basson acted unethically during his work on the apartheid government’s chemical and biological weapons project, Project Coast, during the 80s and early 90s.

In his defence, Basson claimed he acted as a soldier and not as a doctor.

One of accusations against him is being involved in the large-scale production of Mandrax, cocaine and teargas and supplying it to Angola’s Unita leader, Jonas Savimbi.

In 2002, Basson was acquitted by the High Court in Pretoria of criminal charges arising from his conduct.

The HPCSA reviewed the judgment to establish if there were grounds to hold an inquiry.

The state appealed against the decision of the high court in the Supreme Court of Appeal, but the appeal was dismissed.

The state then went to the Constitutional Court, but that case was dismissed in September 2005.
