The binding legal principles established are: (1) In cases where an accused claims false accusation, the alleged motives must be analyzed together with all the evidence, and if there is no basis for imputing false accusation, the enquiry proceeds to whether the State has proved guilt beyond reasonable doubt. (2) Evidence of child complainants in sexual offence cases must satisfy cautionary rules relating to young witnesses and single witnesses, but where such evidence is clear, consistent, and corroborated in material respects, and the trial court makes favourable credibility findings including on demeanour, an appeal court will be slow to interfere. (3) Incestuous rape by a parent of a child constitutes one of the most grievous forms of rape, involving abuse of trust, authority, and the family bond that should nurture love and protection. (4) Under section 51(1) of the Criminal Law Amendment Act 105 of 1997, the prescribed minimum sentence of life imprisonment applies to rape of children unless substantial and compelling circumstances justify a lesser sentence. (5) Where an accused fails to adduce evidence of substantial and compelling circumstances, the trial court has no basis to deviate from the prescribed minimum sentence. (6) Lack of remorse, persistence in denying guilt despite overwhelming evidence, and continuation of offending behaviour after initial discovery are aggravating factors in sentencing for sexual offences.
