The binding legal principles established are: (1) Section 51(2) of the Criminal Law Amendment Act 105 of 1997 applies only to regional courts and High Courts, not to district magistrates' courts, regardless of anomalies this creates. (2) For minimum sentencing provisions to apply under the Criminal Law Amendment Act, all elements of the scheduled offence, including value thresholds, must be proved by the State before conviction/verdict, not merely admitted or proved after conviction. (3) A court not bound by minimum sentencing legislation may nevertheless properly have regard to such legislation as one factor reflecting legislative policy and community standards when imposing sentence, provided this does not become the determinative or predominant factor. (4) A misdirection in sentencing is only material if it is of such nature, degree or seriousness that it shows the court did not exercise its discretion at all, or exercised it improperly or unreasonably - mere technical errors are insufficient to warrant appellate interference. (5) In drug trafficking cases, particularly involving hard drugs like cocaine imported from abroad, the interests of society and the need for deterrence generally outweigh the personal circumstances of couriers, even first offenders. (6) An appellate court will not readily interfere with a sentence imposed by a lower court unless it is disturbingly inappropriate or vitiated by material misdirection.
