Imbwaka & 3 others v Republic (Criminal Appeal 83 of 2019) [2025] KECA 92 (KLR)
The bottom line
#Kenya's Court of Appeal upheld four murder convictions but replaced the death sentences with 30 years' imprisonment each, citing the Muruatetu decision.
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 ingredients of the offence of murder were established
- 2.Whether the appellants were positively identified notwithstanding alleged contradictions in prosecution evidence
- 3.Whether the appellants' alibi defences were displaced
- 4.Whether the prosecution's failure to call certain witnesses entitled the court to draw adverse inferences
- 5.Whether malice aforethought was proved
- 6.Whether the information was fatally defective for omitting the words 'jointly with others not before the court'
- 7.Whether the mandatory death sentence was lawful in light of Muruatetu
Key legal issues
#Effect of contradictions and discrepancies in prosecution evidence
The contradictions (dates, times, names, weapons, number of assailants) were minor, typographical or due to human frailty and did not undermine the reliability of the identification by recognition in broad daylight
The court applied the substantive test from Ondeng': only contradictions leaving a reasonable person in doubt vitiate a conviction. The date/time discrepancies were scrivener's errors evident from the handwritten record; the differing name permutations did not erode the witnesses' categorical recognition of the assailants, whom they had known since childhood, in daylight, and whom they named in their first reports to police.
Whether the alibi defences were displaced
The alibis, raised for the first time on the witness stand without prior notice, were completely negated by the strong recognition evidence
While an accused bears no burden of proving an alibi, failure to raise it early is a factor in assessing its weight, and the prosecution may invoke section 309 of the Criminal Procedure Code to rebut it. The alibi prevails only where it raises reasonable doubt. Here the prosecution evidence in its totality eliminated any reasonable possibility that the alibis were true.
Failure to call certain witnesses
Neither the pathologist who did not testify (her report was properly produced under section 77 of the Evidence Act) nor the neighbours who arrived after the attack were essential witnesses; no adverse inference was warranted
Under section 143 of the Evidence Act no particular number of witnesses is required, and under Bukenya an adverse inference arises only where an essential witness is absent and the extant evidence is barely adequate. Neither condition was met, and whether to call a witness is a prosecutorial discretion unimpeached by any oblique motive.
Malice aforethought
Malice aforethought was established under section 206(a) of the Penal Code by the vicious armed attack inflicting multiple extensive cuts
Malice aforethought is distinct from motive. Applying the Tubere factors - nature of weapon, manner of use, part of body targeted, nature of injuries, and conduct of the accused - the repeated cutting with pangas, slashers and rungus showed a clear intention to cause grievous harm. Recovery of the murder weapon is not a legal requirement for conviction.
Defective information
The omission of the words 'jointly with others not before the court' despite six assailants was a technical defect curable under section 382 of the Criminal Procedure Code
Section 382 bars reversal on account of errors, omissions or irregularities unless they occasion a failure of justice, and regard is had to whether the objection could and should have been raised earlier. The court accepted the information should ideally have contained the words but found no prejudice to the appellants.
Mandatory death sentence
The mandatory death sentence, imposed before Muruatetu, was unconstitutional in its mandatory aspect and had to be set aside; the appellate court substituted thirty years' imprisonment for each appellant
The respondent conceded the sentence should be set aside since the trial judge considered herself constrained by the then-mandatory provision in section 204 of the Penal Code before Francis Karioko Muruatetu unshackled sentencing discretion. The court, finding sufficient material including detailed mitigation, itself imposed an appropriate sentence considering youthfulness, first-offender status, remorse and family responsibilities.
Legal principles established
#- A first appellate court must subject the evidence to a fresh and exhaustive examination, weigh conflicting evidence and draw its own conclusions, making allowance for the trial court's advantage of seeing and hearing the witnesses
- Not every inconsistency in prosecution evidence introduces reasonable doubt; the test is whether the contradictions are such that a reasonable person would be left in doubt whether the charges were proved
- Where the only evidence against a defendant is identification or recognition evidence, the court must examine it carefully and be satisfied the circumstances of identification were favourable and free from possibility of error
- An alibi does not shift the burden of proof to the accused, but failure to raise it at the earliest opportunity may affect the weight given to it; it only prevails where it raises reasonable doubt
- The prosecution need not call a multiplicity of witnesses; it must call only a sufficient number to establish a pertinent fact, and whether to call a witness is within its discretion absent oblique motive
- The murder weapon need not be recovered and produced in court for a murder conviction to be sustained; each element of the crime must simply be proved beyond reasonable doubt
- Omission of the words 'jointly with others not before the court' in an information is a curable defect under section 382 of the Criminal Procedure Code where it does not occasion a failure of justice
Court orders
#- 1.The appeal against conviction is dismissed in its entirety
- 2.The appeal against sentence succeeds and the death sentence imposed on each of the appellants is set aside

- On appeal from
- High Court of Kenya
- Jurisdiction invoked
- First appeal to the Court of Appeal against conviction and sentence for murder under the Penal Code
Relief refused
#Setting aside of the convictions for murder
The identification evidence was strong, alibis were displaced, malice aforethought was proved, and the defect in the information was curable under section 382 of the Criminal Procedure Code
Acquittal based on alleged contradictions in prosecution evidence
The discrepancies were minor, typographical or attributable to human frailties and did not go to the elements of the charge
Costs
No costs order was made in the judgment
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.
The upshot is that the appeal against conviction herein is dismissed in its entirety. The appeal against sentence succeeds. The death sentence imposed on each of the appellants is hereby set aside.
In its place, each of the appellants is sentenced to thirty (30) years imprisonment to be computed to begin on 13/10/2017 when the appellants were remanded in custody pending sentencing.
It is not the function of a 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.
not every inconsistency, however small, introduces reasonable doubt to the prosecution case
Such alibi defence will only prevail where it successfully raises reasonable doubt about the probability whether it is the accused person who committed the offence.
our law does not require the murder weapon to be found and produced in court for a guilty verdict in murder to be sustained
this omission did not occasion any prejudice to the appellants; and that the defect is eminently curable under section 382 of the Criminal Procedure Code
Orders accordingly.
Issues in the judgment
#The judgment refers to 'the appellant' in the singular in places despite four appellants, and the memorandum of appeal numbering is internally confusing (a fifth lettered sub-item 'e' interrupts the list of grounds 'd' and 'e')
The trial court's quoted judgment describes PW3, Mayemula Mutola Malale, as 'the father to the deceased' while the appellate judgment itself records her as the deceased's mother
