The appellant, Edmore Nyarugwe, was a police officer stationed at Victoria Falls Border Post. On 28 July 2014, he was charged with criminal abuse of office (alternatively bribery) for allegedly accepting US$300 from Tariro John Mundozo, Augustine Chasaya and Ronald Chasaya to facilitate smuggling of goods into Zimbabwe without declaring them to ZIMRA officials. It was further alleged that he offered US$100 to Rufaro Mvududu, a ZIMRA official, to allow the truck safe passage without inspection. The appellant pleaded not guilty, denying any knowledge of or meeting with the three men in the truck, and denying offering any bribe to Rufaro. He was convicted by the magistrate's court and sentenced to a fine of US$400 or 6 months imprisonment, plus 3 months imprisonment suspended for 3 years.
The appeal against conviction and sentence was upheld. The conviction was quashed and the sentence was set aside.
1. A prior inconsistent statement of a witness declared hostile does not itself become evidence and cannot be relied upon as substantive evidence to prove the prosecution's case or to corroborate other evidence. 2. Where a hostile witness has been cross-examined by the party calling them, their evidence can only be considered if portions of their oral testimony in court incriminate the accused - the prior statement alone cannot serve this purpose. 3. Proof beyond reasonable doubt in criminal cases demands more than merely believing one witness and disbelieving the accused; a defence must succeed whenever it appears reasonably possible that it might be true. 4. Where state witnesses give contradictory versions of events, a court cannot simply reject one version on speculative grounds (such as assuming bias) without proper evaluation of the objective evidence.
The Court noted that even where a witness's credibility has been impeached by production of a prior inconsistent statement, this does not mean their adverse evidence must necessarily be rejected - it remains evidence that must be properly examined. However, the weight of such evidence will usually be substantially affected by the equivocation of the witness. The Court also observed that it was surprising that if Rufaro had truly reported the incident to her supervisor, the supervisor did not report the matter to police at the border, suggesting doubt about whether the incident actually occurred as alleged.
This case is significant in Zimbabwean criminal law and evidence for clarifying the proper treatment of hostile witness testimony and prior inconsistent statements. It reinforces the principle that prior inconsistent statements cannot be used as substantive evidence to prove a case, but only to neutralize adverse testimony. The judgment also emphasizes the high standard of proof beyond reasonable doubt in criminal cases, and that this standard requires more than merely believing the complainant and disbelieving the accused - it demands that a defence succeeds whenever it appears reasonably possible that it might be true. The case serves as an important reminder to trial courts about the dangers of relying on impeached evidence and the need for objective assessment of all evidence.
