The State v Michael Nyamukondiwa

The appellant was charged with theft of trust property under section 113(2) of the Criminal Law (Codification and Reform) Act. The complainant, a junior officer in the Zimbabwe Prison Service, alleged that on 10 February 2009, while reporting for duty at Harare Remand Prison, he had his Nokia E90 cellphone with a US$100 note beneath its battery. The appellant, a Chief Superintendent and officer in charge, confiscated the cellphone citing Standing Rules prohibiting cellphones in the prison complex. At a disciplinary hearing on 3 March 2009, a different cellphone (Vodafone 125) was produced. The appellant denied receiving a Nokia E90 and maintained he only received the Vodafone that was later produced. He was convicted by the magistrate and sentenced to 6 months imprisonment (3 months suspended for good conduct, 3 months suspended on condition of restitution).

• Whether the trial court erred in convicting the appellant when the evidence did not warrant a conviction
• Whether the trial court misdirected itself by accepting uncorroborated evidence of the complainant regarding possession of the Nokia E90 cellphone
• Whether the trial court erred in ruling inadmissible the evidence of the defence witness Nunurai Mudzverengi
• Whether grounds of appeal were properly formulated in compliance with Supreme Court Rules
• Whether the evidence of a single witness with an interest to serve was sufficient for conviction without corroboration

The appeal against conviction was allowed. The conviction was set aside and the verdict was altered to read: "The appellant is found not guilty and acquitted."

Where a conviction is based on the evidence of a single witness who has an interest to serve or a possible motive to falsify evidence, such evidence must be treated with caution and requires careful scrutiny. The evidence must be clear and satisfactory in every material respect, and corroboration should be sought. Hearsay evidence cannot constitute proper corroboration. A witness's relationship with a party or interest in the outcome affects the weight to be given to their evidence, not its admissibility. The court may only convict where the evidence establishes guilt beyond reasonable doubt, and in the absence of clear, satisfactory and corroborated evidence from a single interested witness, a conviction is unsafe.

The court observed that US$1000 was "a lot of money by any standard" and commented on the unlikelihood of someone parting with such a substantial sum without obtaining the seller's details in case of malfunction or the property being stolen. The court also noted that grounds of appeal stating merely that "the evidence did not warrant a conviction" or that "the trial court erred in accepting the complainant's evidence" are not proper grounds of appeal as they do not comply with the requirement to "set out clearly and specifically" the ground of appeal. The court cited with approval the principle from S v Svosva that there is no rule requiring a credible witness to remember all minor details of an incident, and that forgetfulness regarding minor details does not make a witness less credible.

This case reinforces important principles in criminal evidence law regarding: (1) the cautious approach required when dealing with single witness testimony, particularly where that witness has an interest to serve; (2) the need for corroboration of evidence from witnesses with possible motives to falsify; (3) the distinction between admissibility and weight of evidence - that a witness's relationship with a party affects credibility assessment rather than admissibility; (4) the proper treatment of hearsay evidence and its limitations in providing corroboration; (5) the requirement that evidence must be clear and satisfactory in every material respect before conviction can be sustained; and (6) the importance of properly formulating grounds of appeal in compliance with procedural rules.
