Kinyanjui v Republic
The bottom line
#Kenya's Court of Appeal quashed a death sentence, ruling that a conviction based only on fingerprint evidence must exclude every other reasonable explanation.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the magistrate misdirected himself in holding that the burden was on the accused to explain how his fingerprints came to be at the scene of crime
- 2.Whether the fingerprint evidence alone was sufficient and safe to sustain a conviction for robbery with violence
Key legal issues
#Burden of proof regarding fingerprints found at a crime scene
The magistrate's statement that it is established law that the accused must explain how his fingerprints came to be at the scene was incorrect; the accused need only raise a reasonable doubt.
The court held the magistrate misdirected himself by placing an evidential burden on the accused to explain the presence of his fingerprints. The correct position is that the accused need only raise a reasonable doubt. However, on the facts, the court found the appellant's evidence raised no such doubt, so the misdirection was not decisive of the appeal.
Sufficiency and safety of fingerprint-only evidence
A conviction based solely on fingerprint evidence is unsafe unless the circumstances point to guilt to the exclusion of any other reasonable hypothesis; here gaps in the chain of evidence made the conviction unsafe.
The lifted print was a palm print whose origin was unproven - no photograph of the surface or negative was produced. Multiple sets of fingerprints were taken without satisfactory explanation, and three eyewitnesses failed to identify the appellant at parades. These discrepancies, unexamined by the courts below, rendered the conviction unsafe.
