1. For culpable homicide under s 49 of the Criminal Law (Codification and Reform) Act, the State must prove that: (a) the accused's conduct was both the factual and legal cause of death; and (b) a reasonable person would have foreseen that such conduct would result in death and would have taken reasonable steps to avoid it. 2. Where a sustained and brutal assault using weapons results in serious injuries (including disgorged eye, deep lacerations, head injuries) and the victim dies soon after from head injuries, the assault is both the factual and legal cause of death, and death was reasonably foreseeable. 3. Credible eyewitness testimony from multiple witnesses observing from different vantage points, which is consistent with objective medical evidence and not dislodged in cross-examination, is sufficient to establish guilt even if the witnesses are victims of the same incident. 4. An appellate court should only interfere with sentence if the trial court's discretion was not exercised judicially and properly, or if the sentence is vitiated by irregularity, misdirection or is disturbingly inappropriate. 5. Culpable homicide arising from violent gang assaults invariably attracts a custodial sentence, reflecting the constitutional imperative to protect the sanctity of human life.
