An appellate court will only interfere with a sentencing court's discretion where there is a misdirection or the sentence imposed is manifestly excessive. In cases of rape of very young children by persons in positions of trust who also infect the victim with sexually transmitted diseases, a sentence of 18 years imprisonment (with partial suspension) is not manifestly excessive and may even be considered lenient, given that section 65(1) of the Criminal Law (Codification and Reform) Act provides for a maximum sentence of life imprisonment. The aggravating factors under section 65(2) - particularly the age of the victim, the position of trust, and transmission of a sexually transmitted infection - justify substantial custodial sentences.
