Peter Mwangi Wanjiku v Republic [2020] KECA 469 (KLR)
The bottom line
#Kenya's Court of Appeal freed a man sentenced to death after finding that shaky witness identification and an unfair shift of the burden of proof made his robbery conviction unsafe.
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 learned Judge properly directed herself and properly considered the evidence of identification
- 2.Whether the learned Judge properly reconsidered and re-evaluated the evidence adduced before the trial court, and if so whether the evidence was sufficient to sustain the appellant's conviction
- 3.Whether it is open to the Court of Appeal to reconsider and review the sentence imposed on the appellant
Key legal issues
#Whether the identification evidence of a single witness was safely tested
The trial and first appellate courts did not adequately test the single witness's identification evidence: no inquiry was made into the nature and source of the lighting, no description of the assailants appeared in the first report or statement, and the possibility of mistaken identification was not ruled out.
Although Section 143 of the Evidence Act permits conviction on a single witness, Maitanyi requires careful testing of identification evidence, especially in difficult conditions. The complainant said the lights came from a nearby plot, but no inquiry established the distance, position, or nature of the lights. His first report and police statement contained no description or name of any assailant. The night-time, stressful circumstances left open the possibility of honest but mistaken identification.
Failure to call crucial witnesses
The passenger present during the attack, the police officer who received the first report, and the boda boda riders who assisted in the arrest were crucial witnesses, and no reason was given for the failure to call them.
While the prosecution has discretion over which witnesses to call, Bukenya establishes that it must make available all witnesses necessary to establish the truth, and that where the evidence called is barely adequate, an adverse inference may be drawn from the non-calling of material witnesses. On a conviction resting on a single identifying witness, the absence of these witnesses without explanation undermined the safety of the conviction.
Shifting of the burden of proof
The High Court erred by holding that the burden lay on the appellant to adduce evidence of an alibi to remove himself from the scene.
Despite correctly stating the law on single-witness identification, the first appellate court misdirected itself in law by requiring the appellant to account for his whereabouts. The burden of proving the case beyond reasonable doubt rests on the prosecution throughout; the accused has no responsibility to give an alibi or prove anything. This misdirection constituted an error of law on a second appeal.
Duty of the first appellate court to re-evaluate evidence
Although the High Court correctly directed itself by citing Okeno, it failed to discharge the duty of reconsidering and re-evaluating the evidence, and had it done so it would have found the identification evidence unsafe.
Okeno requires the first appellate court to make its own findings and draw its own conclusions, making allowance for the trial court's advantage of seeing and hearing witnesses. Here the Judge reproduced the correct principles but did not apply them: she did not test the impression received by the sole witness at the time of the incident or the description given to those who came to his aid. The failure to analyse and evaluate was itself an error of law.
Sentence
The High Court's remission to the trial court for re-sentencing was within its powers and raised no issue for the Court of Appeal, but the sentence could not stand once the conviction was quashed.
The State argued the sentence issue was premature because the High Court made no determination on sentence but remitted for re-sentencing. The Court found the remission lawful and within the High Court's powers. However, since the death sentence was predicated on the conviction, the finding that the conviction was unsafe necessarily required the sentence to be set aside as well.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact unless they are based on no evidence, wrong principles, or are plainly wrong.
- Evidence of a single identifying witness must be tested with the greatest care, and failure to undertake such careful testing is an error of law rendering the evidence unsafe to support a conviction.
- The burden of proof remains on the prosecution throughout; an accused has no obligation to give an alibi or prove anything.
- Where the evidence called by the prosecution is barely adequate, the court may infer that the evidence of uncalled witnesses would have been adverse to the prosecution.

Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
Accordingly, we allow the appeal against both conviction and sentence, quash the appellant’s conviction and set aside the death sentence that was imposed upon him. The appellant shall forthwith be released unless otherwise lawfully held.
We cannot interfere with the decision of the superior court on facts unless it is demonstrated that the trial court and the first appellate court considered matters they ought not to have considered or that they failed to consider matters they should have considered
Failure to undertake an inquiry of careful testing is an error of law and such evidence cannot safely support a conviction.
The appellant had no responsibility to give any alibi or prove anything. The burden of proof remained upon the prosecution to prove the case against the appellant and the learned Judge erred in shifting the same to the appellant.
Where the evidence called is barely adequate, the court may infer that the evidence of uncalled witnesses would have tended to be adverse to the prosecution.
it is not the function of the first appellate court merely to scrutinize the evidence to see if there was some evidence to support the lower court’s findings and conclusions; it must make its own findings and draw its own conclusions
Issues in the judgment
#The judgment cites Karani v R and David Njoroge as statements of this Court's own mandate, and the extracts are quoted in the judgment's own voice, so these authorities are treated as adopted by the court rather than merely cited by parties; however, the Muruatetu and Gitonga citations appear in the narrative of the first appeal and of the respondent's submissions, making their treatment by this Court ambiguous.
