The binding legal principles established are: (1) Evidence of rape can be proven beyond reasonable doubt even where medical evidence is inconclusive, provided that there is credible testimony from the complainant, supported by corroborative evidence such as DNA evidence and the accused's inability to explain incriminating physical evidence. (2) When assessing evidence in rape cases, courts must evaluate the evidence in its totality rather than considering each piece of evidence in isolation. (3) Under minimum sentencing legislation (section 51 of the Criminal Law Amendment Act 105 of 1997), courts retain a duty to assess in every case whether the prescribed sentence is proportionate to the particular offence, taking into account all circumstances of the case, before imposing the prescribed sentence. (4) A sentence of life imprisonment for rape, even of a child by a family member, may be disproportionate where: (a) the offender is a first-time offender with prospects for rehabilitation; (b) the rape, while serious, was not the most severe form (no additional violence, offender desisted, no serious physical injuries); (c) there is no evidence of ongoing severe trauma to the victim; and (d) other mitigating circumstances exist. (5) The absence of serious physical injuries to a rape complainant may be considered (along with other factors cumulatively) when determining whether substantial and compelling circumstances exist to deviate from a prescribed minimum sentence, as a literal interpretation of section 51(3)(aA)(ii) that would prevent such consideration would be unconstitutional. (6) Proportionality remains the cornerstone of sentencing even in the context of minimum sentencing legislation, and courts must ensure that punishment fits the crime, the criminal, and the circumstances of the case.
