The binding legal principles established are: (1) In sexual offence cases involving minor children, the credibility and reliability of the child complainant, assessed through demeanor and consistency of account, is the primary basis for conviction, and conviction does not solely depend on production of physical exhibits; (2) Where an accused has had legal practitioners who come and go, and there is no evidence on record that the court refused reasonable requests for postponements or adjournments, there is no denial of the right to legal representation; (3) An alibi defence may be rejected where it is contradicted by evidence, including evidence from the accused's own witnesses; (4) There is no requirement to prove through documentary evidence facts that are not genuinely in dispute, particularly where the accused's defence is based on different grounds (such as alibi rather than challenging the disputed fact); (5) In sentencing for rape of a minor by a person in a position of trust, substantial custodial sentences are appropriate, and sentences in the region of 17-20 years (with partial suspension) do not induce a sense of shock where aggravating factors include breach of trust, the victim's tender age, use of threats, and subsequent flight.
