The appellant (accused 3) was charged with two others for murder, robbery with aggravating circumstances, and unlawful possession of a firearm following an incident on 1 November 2000. The deceased was shot during a robbery at a butchery where approximately R8 000 in cash and R10 000 in cheques were stolen. Witnesses identified accused 1 and 2 in an identification parade as the attackers. The appellant was not identified in the parade. The State's case against the appellant relied primarily on the testimony of Mr Mabena, who testified about a discussion at a shebeen regarding the planned robbery, and two bank deposit slips found in the appellant's bedroom showing deposits of R2 000 each into the accounts of the appellant and accused 2 on the same day, at the same bank, with the same teller. The appellant pleaded not guilty, exercised his right to remain silent, and did not testify. He was convicted in the trial court and sentenced to life imprisonment for murder and 25 years for robbery.
1. The appeal is upheld. 2. The order of the court a quo is set aside (only in respect of the appellant) and substituted with: "Accused 3 is found not guilty and discharged on all counts."
Where a conviction is sought based on circumstantial evidence, the proved facts must not only be consistent with guilt but must exclude every other reasonable inference. The mere presence of suspicious circumstances, such as deposit slips showing banking transactions on the same day, without more, does not satisfy the Blom test where multiple reasonable innocent explanations exist. An accused person's election to remain silent cannot be used to supplement an inadequate State case or to convert suspicion into proof beyond reasonable doubt. The weight of silence depends on the strength of the evidence calling for an answer. For a conviction based on common purpose, courts must evaluate the evidence against each accused separately and individually to determine whether all elements of the doctrine have been proved beyond reasonable doubt in respect of each accused. Inferences may not be drawn from other inferences; they must be based on facts proved beyond reasonable doubt.
The court made observations about the improper manner in which the prosecution questioned witness Mabena, noting it was "not only wrong but also unfair both towards Mabena and the appellant" to ask whether the appellant agreed to a plan when the witness had clearly testified he was uncertain whether the appellant was even present during the discussion. The court also noted that it would have been "highly improbable that a person who is, at the crucial time, outside and clearly not party to the discussion, would be able to agree to anything suggested." The court stated it was "strange" that the prosecution twisted its questions in the manner it did. The court also commented that the discovery of the deposit slips "hardly satisfies the first rule of logic in Blom" and that relying on them for conviction "would stretch inferential reasoning too far."
This case reaffirms fundamental principles in South African criminal law regarding circumstantial evidence, the burden of proof, and the right to silence. It emphasizes that: (1) circumstantial evidence must satisfy the strict requirements in R v Blom; (2) inferences of guilt must be the only reasonable inference from proved facts; (3) an accused's silence cannot be used to supplement a weak State case; (4) suspicion, no matter how strong, cannot ground a conviction; (5) courts must evaluate evidence against each accused separately when dealing with common purpose; and (6) the State bears the burden of proving guilt beyond reasonable doubt throughout. The judgment provides important guidance on the proper application of S v Boesak principles regarding an accused's election not to testify, clarifying that silence only becomes significant where there is substantial evidence calling for an answer.
