1. Sections 64(1) and 70(4)(a)(i) of the Criminal Law (Codification and Reform) Act must be read harmoniously together. Section 64(1) is peremptory and requires that persons accused of sexual intercourse with young persons "of or under the age of twelve years" must be charged with rape, unless there is evidence the young person was capable of consenting and did consent. 2. The reference in Section 70(4)(a)(i) to "below the age of twelve years" does not oust the specific provisions of Section 64(1) which includes those aged 12 years. Young persons of and under age 12 are incapable of consenting to sexual intercourse in law. 3. The definition of "young person" in Section 61 as "a boy or girl under the age of 16 years" must be read with Section 64(1), such that for purposes of Section 70 offences, "young persons" means those aged 13 years and below 16 years, while those aged 12 and under fall under the rape provisions. 4. Where an unrepresented accused qualifies a guilty plea by denying an essential element of the offence, the magistrate must alter the plea to not guilty and allow the accused to ventilate the defence. 5. In cases involving sexual abuse of children, exact ages must be determined through birth certificates and/or medical evidence, not mere allegations in charge sheets.
