The binding legal principles established are: (1) At the stage of a section 174 application for discharge, the test is whether there is evidence upon which a reasonable court, acting carefully, might convict; credibility findings play a limited role at this stage. (2) An application to reopen a criminal case should only be granted where the applicant provides: (a) a reasonably sufficient explanation for why the evidence was not led at trial; (b) a prima facie likelihood of the truth of the evidence; and (c) that the evidence is materially relevant to the outcome of the trial. (3) In cases based on circumstantial evidence, the Blom test applies: the inference sought must be consistent with all proved facts and must exclude every other reasonable inference. (4) An accused's version cannot be rejected solely because it is improbable; it may only be rejected once the court finds on credible evidence that the explanation is false beyond reasonable doubt. (5) Where there has been an irregularity in criminal proceedings, a conviction will only be set aside if there has been a failure of justice. This requires asking whether, on the evidence unaffected by the irregularity, guilt is established beyond reasonable doubt. Only in exceptional cases where the irregularity constitutes such a gross departure from established procedure that the accused was not properly tried will it constitute a failure of justice per se. (6) In sentencing murder cases under the Criminal Law Amendment Act, courts must carefully distinguish between section 51(1) (premeditated murder, minimum life imprisonment) and section 51(2) (murder, minimum 15 years). Premeditation must be established on proper evidence, not mere inference. (7) In cases involving sustained domestic abuse of the offender by the deceased, courts must evaluate the abuse not from an objective or male perspective but by placing themselves in the position of the woman concerned, with full regard to the abusive relationship and expert evidence. This gives effect to the offender's equality rights under section 9(1) of the Constitution. (8) Even in serious cases such as murder, where substantial and compelling circumstances exist (including age, clean record, history of severe abuse, psychological trauma, unlikelihood of reoffending, and family consequences), courts should consider non-custodial sentences under section 276(1)(h) after compliance with section 276A(1)(a) of the CPA.
