The appellant, Joshua James Button, pleaded guilty in the regional court sitting in Krugersdorp to two counts of rape committed in 2018 and 2019 while he was a detainee at the Bosasa Youth Centre. The complainants were fellow detainees aged 15 and 17. In a pre-sentence report, the probation officer recorded, without medical verification, that the appellant was HIV-positive and aware of his status, and that one complainant (CR) had allegedly contracted HIV as a result of the rape. The regional court relied heavily on this alleged HIV-positive status as a weighty aggravating factor and sentenced the appellant to life imprisonment on count one and ten years on count two. The Gauteng Division of the High Court dismissed his appeal against sentence, again relying on the asserted HIV-status. Before the Supreme Court of Appeal, the appellant applied in terms of s 19(b) of the Superior Courts Act 10 of 2013 to adduce further medical evidence. The evidence comprised affidavits and a report from Lancet Laboratories confirming that a blood sample taken from the appellant on 5 December 2023 tested non-reactive (negative) for HIV-1 and HIV-2, and that an expert clinical virologist confirmed it is medically impossible for a truly HIV-positive person to later test negative without a stem cell transplant, which the appellant had never undergone. The appellant explained that he had not controverted the pre-sentence report at trial because his legal representative had given him only five minutes to read it and he did not appreciate the HIV reference until addresses were made.
