Michael Saa Wambua & another v Republic [2017] KECA 236 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a robbery conviction and death sentence, confirming that minor charge sheet errors do not defeat justice when no prejudice is shown.
What this practically means
#Executive summary
#Key legal issues
#Whether failure to indicate the time of the offence in the charge sheet rendered the charge defective and fatal
The omission was not fatal; no prejudice was occasioned, and by section 382 CPC the conviction stands where no failure of justice occurred
Sections 134 and 214 of the Criminal Procedure Code govern charge requirements and curative amendment. The appellants did not demonstrate any prejudice from the omission to state the time. Undisputed evidence showed the offence occurred at night on the very night the appellants were drinking at the deceased's bar. The point was raised for the first time on second appeal and treated as an afterthought. Section 382 CPC cures any irregularity not occasioning a failure of justice.
Whether failure to call a crucial witness vitiates the conviction
No; the prosecution has discretion on which witnesses to call, and failure to call the teacher, mother and sister was not prejudicial
The court invoked Mwangi v Republic on prosecution discretion, section 143 of the Evidence Act (no particular number of witnesses required), and Bukenya v Uganda on the duty to call necessary witnesses. The uncalled witnesses' testimony would merely have repeated uncontested facts (reporting the incident, recovery of exhibits). The dispute was identity, resolved by the credible eyewitnesses Robert and Raphael, whose credibility findings were concurrent findings of fact not interferable with on second appeal.
Whether the appellants' alibi defences were rebutted
Yes; the alibis were ousted by the totality of the prosecution evidence, particularly the two eyewitnesses
Section 309 CPC permits prosecution rebuttal of new matter raised in defence. The court held an alibi may be rebutted by calling rebuttal evidence or by weighing it against the totality of the prosecution case. Both courts below weighed the alibis against the evidence of the eyewitnesses who recognized the appellants and found the prosecution evidence truthful and credible. The court affirmed that rejection as it was a concurrent finding of fact.
Legal principles established
#- A second appellate court confines itself to points of law only and will not interfere with concurrent findings of fact of the two courts below unless those findings were based on no evidence
- Not every conflict between the particulars of a charge and the evidence vitiates a conviction; only conflicts causing discernible prejudice do
- Whether a witness is called by the prosecution is within the prosecution's discretion, which the court will not interfere with absent an oblique motive
- An alibi may be rebutted either by prosecution evidence in rebuttal or by the court weighing it against the totality of the prosecution case
- Discrepancies in prosecution evidence do not per se vitiate the case where they do not affect an otherwise proved case
