The binding legal principles are: (1) An appellate court can only interfere with a sentence imposed by a lower court where there has been an irregularity resulting in failure of justice, the court misdirected itself to such an extent that its decision on sentence is vitiated, or the sentence is so disproportionate or shocking that no reasonable court could have imposed it (applying S v Bogaards); (2) A sentence under s 276(1)(i) of the CPA is appropriate where a custodial sentence is essential but an extended period of incarceration is inappropriate, as it mitigates the sentence by creating prospect of early release on correctional supervision after serving one-sixth of the sentence (applying S v Scheepers); (3) In sentencing for sexual offences against children, aggravating factors include: positions of trust and authority, significant age differences, grooming behavior, violation of court protection orders, manipulation of the victim, and lack of genuine remorse or acceptance of responsibility; (4) The existence of what the offender characterizes as a 'love relationship' does not mitigate sexual offences against children, particularly where the accused occupied a position of authority and engaged in grooming behavior.
