#Sufficiency of expert handwriting evidence to sustain a forgery conviction
The document examiner's opinion evidence alone, without corroboration, cannot support a conviction for forgery.
The court re-evaluated the evidence and found that no SACCO witness connected the Appellant to the forgery; the only linking evidence was the document examiner's opinion. The Appellant was not the only employee authorised to write cheques, and the magistrate treated the expert's opinion as the truth without testing it against other evidence.
Gaps in the prosecution case - uninvestigated beneficiaries and signatories
Failure to investigate the beneficiaries of the forged cheques and who forged the official signatories' signatures weakened the prosecution case below the required standard.
The beneficiaries named in the charge sheet could not have cashed the cheques without presenting identity cards, yet police did not investigate them. Similarly, no evidence showed who forged the signatures of the official signatories, without which the cheques could not have been encashed even if the Appellant wrote them.
First appellate court's duty to re-evaluate evidence
The first appellate court must weigh conflicting evidence and draw its own inferences, subject to due allowance for not having seen or heard the witnesses.
Relying on Njoroge v Republic, the court restated the duty of the first appellate court on questions of fact and law, then applied it by independently re-evaluating the trial evidence rather than deferring to the magistrate's findings.
