The binding legal principles established by the majority are: (1) Evidence of a child witness can sustain a conviction if the court is satisfied that the evidence is trustworthy, which depends on factors such as the child's power of observation, recollection, and narration on the specific matter testified. (2) Minor contradictions in a child witness's evidence, particularly regarding details such as the exact position during a rape, do not necessarily render the evidence unreliable where the child was not asked to volunteer such details and may not have understood the need to be precise about such matters due to age and the intimidating atmosphere of testifying. (3) The credibility of a child witness relates to honesty, while reliability relates to cognitive ability or brain development, assessed by factors such as ability to encode, retain, retrieve and recount information. (4) The evidence of a single witness must be clear and satisfactory in every material respect to sustain a conviction, but this does not mean such evidence must be flawless and beyond criticism. (5) While section 60 of the Sexual Offences Act prevents use of caution merely because an offence is sexual in nature, courts should not convict on the evidence of a child as a single witness unless such evidence is treated with caution. (6) An accused must be warned of the applicability of minimum sentence legislation at the time when he tenders his plea; failure to do so constitutes a serious misdirection vitiating the sentencing proceedings and warranting the court to consider sentence afresh. (7) The reconstructed record must show that the accused was warned of penal provisions; it is not sufficient merely to state that this was explained.
