Samson Somali Koskei v Republic [2016] KECA 295 (KLR)
The bottom line
#Kenya's Court of Appeal freed a man sentenced to death for robbery, ruling that broken, circumstantial evidence cannot justify a conviction.
What this practically means
#Executive summary
#Key legal issues
#Scope of jurisdiction on a second appeal
The Court considers only issues of law and is bound by concurrent findings of fact unless shown not to be based on evidence.
Section 361(1)(a) of the Criminal Procedure Code limits second appeals to matters of law. The court cannot re-open findings of fact made concurrently by the trial court and the High Court; it may intervene only where such findings are shown not to be founded on the evidence, as held in Thiongo v R.
Conviction on circumstantial evidence and the unbroken chain rule
The chain of circumstantial evidence must be complete and unbroken; where broken by discrepancies going to the root of the prosecution, the discrepancies are resolved in favour of the accused.
The case against the appellant was largely circumstantial. There was no evidence linking the appellant to the scene apart from the victims' testimony; exhibits and the homemade gun were not directly linked to him; the arresting officer did not testify and the investigator acted on hearsay. These breaks in the chain, in a capital case demanding watertight evidence, were fatal to the conviction.
Standard of care required by the prosecution in capital cases
Because a conviction attracts a mandatory death sentence, the prosecution must exercise greater caution and adduce watertight evidence; the burden of proof always rests on the prosecution.
The court emphasised that faced with a mandatory death sentence, investigators and prosecutors must pursue alternative hypotheses, eliminate doubts, and call essential witnesses such as arresting officers. A casual approach, as exhibited here, leaves discrepancies that go to the root of the prosecution and cannot sustain a conviction.
Reconciliation of discrepancies under section 382 Criminal Procedure Code
An appellate court must reconcile alleged discrepancies in witness testimony and determine whether they go to the root of the prosecution so as to affect an otherwise proved case.
Discrepancies are inevitable in any trial. The High Court, as first appellate court, must reconcile them under section 382 of the Criminal Procedure Code, guided by the court's previous decisions in Vincent Kasyula Kingo v Republic and Njuki & 4 others v Republic. Here the discrepancies went to the root of the prosecution and resolved in the appellant's favour.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to issues of law and is bound by concurrent findings of fact of the lower courts unless those findings are not based on evidence.
- A conviction on circumstantial evidence is justified only where the inculpatory facts are incompatible with the innocence of the accused and incapable of explanation on any other reasonable hypothesis, and the burden of proving this never shifts to the accused.
- In a case based wholly on circumstantial evidence, every element of the unbroken chain of evidence must be adduced by the prosecution and the chain must never be broken at any stage.
