Lukas Wanyenye Njoki v Republic
The bottom line

#Scope of the Court's mandate on second appeal
The mandate is limited to matters of law only under section 361(1) of the Criminal Procedure Code; the first appellate court's approach showed it was alive to the applicable principles, and the Court declined to reproach it.
The Court invoked section 361(1) of the Criminal Procedure Code and the Dzombo decision, reaffirming that matters of fact are for the trial court and first appellate court, and that interference is warranted only where the courts below considered or failed to consider matters they should have, or were plainly wrong on the evidence. Applying that standard, the High Court judges were properly seized of the Pandya and Coghlan thresholds, so the first ground failed. However, the remaining legal errors in the treatment of identification evidence vitiated the convictions.
Recognition versus identification of the appellant by PW9
Recognition did not apply because PW9 did not know the appellant prior to the incident; the High Court was right to so hold. Equally, evidence of identification was doubtful and unsustainable.
The Court set out the requirements for sustaining recognition evidence (prior acquaintance, duration, reasons for certainty) and for identification evidence (circumstances, source of light, striking features, proximity, impediments, and prompt description to police). PW9 repeatedly stated he could not see the abductors clearly, was blindfolded, and the houses were unlit. His identification of the appellant at the police station a week later was therefore doubtful, and doubt must be resolved in the accused's favour.
Conviction on the evidence of a single identifying witness
Both courts below failed to warn themselves of the dangers of acting on the evidence of PW9, a single identifying witness, and to give reasons for doing so; the convictions were consequently unsafe and stood vitiated.
PW9's evidence was the sole foundation of the convictions on counts III, IV, V, VI and VII. The Court held that where a conviction rests on a single identifying witness, the trial court and first appellate court are obliged in law to warn themselves of the dangers of acting on such evidence and give reasons; neither did. Once the sole identifying evidence faltered, there was no other basis for sustaining the convictions, which were therefore vitiated.
Failure to call crucial witnesses
The complaint failed: the appellant did not specify the crucial witness not called, and the identification parade evidence having been discounted by the trial court, no prejudice arose from the officer's absence.
The Court cited section 134 of the Evidence Act and Mwangi vs. Republic for the proposition that the number and identity of prosecution witnesses is a matter of discretion, qualified by Bukenya vs. Uganda's obligation to call witnesses necessary to establish the truth, but not a superfluity of them (Keter vs. Republic). Since the parade evidence was discounted and formed no part of the basis of conviction, the appellant suffered no prejudice. The complaint was rejected.
Burden of proof, alibi and sentence
These issues were not interrogated because the determination on identification evidence effectively disposed of the appeal, rendering consideration of them unnecessary.
Having vitiated the concurrent findings on conviction, the Court declined to address the alleged shifting of the burden of proof, the sufficiency of proof beyond reasonable doubt, and the legality or fairness of the sentence, since addressing them would be an exercise in futility. The appeal was allowed in its entirety on the identification/single-witness ground alone.
Legal principles established
#- In a second appeal, the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact unless no reasonable tribunal could have reached the conclusion on the evidence
- For evidence of recognition to be sustained, the witness must state that he or she knew the assailant prior to the incident, the length of time known, and reasons for certainty of recognition
- Where a conviction rests solely on the evidence of a single identifying witness, both the trial court and the first appellate court are obligated to warn themselves of the dangers of acting on such evidence and give reasons before doing so
- No particular number of witnesses is required to prove any fact; whether a witness is called is a matter for the prosecution's discretion, subject to the Bukenya obligation to call witnesses necessary to establish the truth
- Failure to call the officer who conducted an identification parade causes no prejudice where the parade evidence was discounted by the trial court and formed no part of the basis of conviction
