The appellant was convicted of murder in the Regional Court, Kimberley. A party was held at the appellant's house. The deceased, Mrs Tyro Guys, came to call her husband away from the party. An altercation developed between the deceased and party guests, then with the appellant's mother. The appellant intervened and told the deceased to leave. He escorted or followed her into the street where a verbal dispute turned into physical aggression. The appellant struck the deceased while holding a glass in his hand. The deceased was seen bleeding profusely from her neck area and died minutes later after collapsing in her yard. The post-mortem examination revealed three injuries: a 1cm triangular laceration near the right eye, an 11cm superficial laceration from below that wound to the corner of the mandible, and a 10cm x 7cm incised wound in the neck extending obliquely from below the right mandible to the collarbone notch. The cause of death was gross blood loss from laceration of the subclavian artery. The central factual dispute was whether the appellant struck one blow (defence version) or two blows - first to the face breaking the glass, then stabbing the neck with the broken glass (State witness Emma Guys' version).
The appeal against the murder conviction was dismissed.
When applying the test of whether there is a reasonable possibility that an accused might be innocent, a court must account for all the evidence and cannot simply ignore aspects of it, including the accused's own version. Expert evidence suggesting a 'possibility' supporting the defence case must be considered in its full context, including any qualifications or conditions attached to such concessions. Where expert evidence states that injuries could 'possibly' have been caused in a particular manner, but only if certain conditions are met (such as a downward trajectory of a blow), and the accused's own evidence demonstrates those conditions were not present (a horizontal blow), there is no reasonable possibility that the accused's version is true. Where an accused stabs a deceased in a vital area (the neck) with a broken glass, the proper inference is that he foresaw death as a possible result and acted with dolus eventualis, warranting a murder conviction.
The Court cited with approval the test articulated in S v Van der Meyden 1999 (2) 79 (W) at 82: 'The proper test is that an accused is bound to be convicted if the evidence establishes his guilt beyond reasonable doubt, and the logical corollary is that he must be acquitted if it is reasonably possible that he might be innocent. The process of reasoning which is appropriate to the application of the test in any particular case will depend on the nature of the evidence which the court has before it. What must be borne in mind, however, is that the conclusion which is reached (whether it be to convict or to acquit) must account for all the evidence. Some of the evidence might be found to be false; some of it might be found to be unreliable; and some of it might be found to be only possibly false or unreliable; but none of it may simply be ignored.' The Court also observed that counsel were in agreement that if the appellant stabbed the deceased with a broken glass in the vital area of the neck, the only reasonable inference must be that he foresaw death as a possible result and acted with dolus eventualis.
This case illustrates the application of the 'reasonable possibility' test in South African criminal law, particularly in cases turning on credibility and expert evidence. It demonstrates how courts must consider all evidence holistically and not selectively ignore the accused's own version when assessing whether a reasonable possibility of innocence exists. The judgment reinforces that expert evidence must be considered in its full context, including qualifications and conditions attached to concessions. It also affirms the deference appellate courts give to trial courts' credibility findings, while emphasizing that credibility alone is insufficient - the court must still be satisfied there is no reasonable possibility the witness was mistaken. The case provides guidance on when dolus eventualis can be inferred in assault cases resulting in death.
