Pretoria - Families of victims of the chemical warfare allegedly administered by Wouter Basson want him struck off the roll as a medical practitioner.
"We cannot do anything as families. All we want is the law to take its course and that Basson be struck off the roll," Mamelodi resident Lizzy Sefulo said on the sidelines of Basson's hearing on Thursday.
Sefulo, 72, said her late husband Harold Sefulo was drugged and tortured with two other anti-apartheid activists by security policemen in 1987.
Sefulo, Jackson Maake and Andrew Makope were abducted and tortured, and their bodies were blown up in the former homeland of Bophuthatswana.
Basson played a major part in their death, said Lizzy Sefulo.
She and several other relatives attended Basson's hearing at the Health Professions Council of SA on Thursday.
They were supported by the human rights group, Khulumani.
Khulumani co-ordinator Mmanoko Mokgonyane alleged that Basson's chemicals and drugs were administered to the victims before they were tortured and killed.
The charges against Basson arise from his involvement in the apartheid government's chemical and biological warfare programme in the 1980s and early 1990s.
He is accused of acting unethically by being involved in the large-scale production of Mandrax, cocaine and teargas, of weaponising teargas, and of supplying it to Angola's Unita leader Jonas Savimbi.
He is also accused of acting unethically by providing disorientating substances for cross-border kidnappings and by making cyanide capsules available for distribution to operatives for use in committing suicide.
In 2002, Basson was acquitted by the North Gauteng High Court in Pretoria of criminal charges arising from his conduct.
The HPCSA reviewed the judgment to establish if there were grounds to continue with an inquiry against Basson.
The State appealed the high court's decision in the Supreme Court of Appeal, but the appeal was dismissed.
The State then went to the Constitutional Court to appeal the decision.
That was also dismissed in September 2005.
