Julius Kiplangat Tanui v Republic
The bottom line
#Kenya's Court of Appeal quashed a robbery conviction because a hostile witness and a drunk eyewitness's shaky identification left too much doubt.
What this practically means
#Executive summary
#Key legal issues
#Credibility of the hostile witness (PW2)
PW2's evidence was wholly unreliable and of no probative value and should not have been considered at all.
PW2 was declared hostile and cross-examined by the prosecution. He gave contradictory accounts - that the complainant was bleeding then not bleeding; that the attackers were unknown persons, then Kapkem, then Leonard Langat alias Kopku and Wesley Kiplangat. Following Batala and Abel Monari Nyanamba, treating a witness as hostile equates to a finding of unreliability, rendering the evidence negligible. The court concluded he was cagey and deliberately untruthful.
Identification by a single identifying witness under unfavourable conditions
The circumstances of identification were not favourable; the complainant's drunkenness, the rainy and muddy night, and material contradictions created doubt as to identity, rendering the conviction unsafe.
PW1 admitted he had been drinking; it was a rainy, muddy night; no medical evidence established his degree of drunkenness. He gave inconsistent figures for the amount stolen (Kshs. 3,750 vs Kshs. 700) and inconsistent weapons. Applying Maitanyi, the evidence of a single identifying witness in difficult conditions must be tested with the greatest care. The court found doubt in the appellant's identity.
Absence of medical evidence and unsafe conviction
The absence of the P3 form/medical evidence left the complainant's claim of injury uncorroborated, contributing to the finding that the conviction was unsafe.
The court noted there was no medical evidence to corroborate that PW1 sustained injuries as alleged; the P3 form was not produced by its maker. Combined with the thin single-witness identification evidence and the complainant's intoxication, the court held this was not a safe conviction, as the evidence relied upon by the prosecution was thin and shaky.
Degree of drunkenness as affecting identification capacity
The state of drunkenness of the identifying witness was a critical issue deserving greater weight, and various degrees of drunkenness may affect the witness's faculties.
Drawing on the South African authority S v Chretien quoting R v Bouke, the court distinguished degrees of drunkenness. No medical evidence was adduced as to the complainant's degree of drunkenness, yet both lower courts simply held that his drunkenness did not affect his ability to identify the culprit. The court held that the state of drunkenness ought to have been given more weight in assessing the complainant's faculties.
Legal principles established
#- A second appellate court concerns itself only with matters of law and may not interfere with findings of fact unless the lower courts considered matters they should not have, failed to consider matters they should have, or were plainly wrong on the evidence.
- The evidence of a witness declared hostile is unreliable and cannot found a conviction; a court cannot convict solely on the evidence of a hostile witness.
- A court must test with the greatest care the evidence of a single identifying witness where conditions favouring correct identification were difficult, and must warn itself before, not after, making its decision.
