Mokgoro J (with concurrence from Moseneke DCJ, Sachs J, Skweyiya J and Van der Westhuizen J) noted that while the crime was heinous and may have deserved a harsher sentence if prosecuted in the High Court, the guarantee of a fair trial applies in all criminal trials regardless of the nature of the offence. The unfairness is not assessed by proportionality between offence and sentence, but by the retrospective application of legislation rendering the sentence unauthorized. The Court declined to make a general order affecting all similarly situated persons, noting that sentencing requires individual consideration and such an order would cause administrative difficulties. O'Regan J (with concurrence from Langa CJ, Ngcobo J and Yacoob J) observed that English courts have held it an abuse of process for a judge to promise a non-custodial sentence and then impose a custodial one. Ngcobo J emphasized the shift from parliamentary supremacy to constitutional supremacy, noting that courts must now interpret legislation to promote the Bill of Rights values rather than relying on common law presumptions, though those presumptions reflected similar concerns about fairness and the rule of law.
