Duncan Thuku Mwangi v Republic [2020] KECA 9 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a murder conviction and death sentence, confirming that strong identification evidence and an abandoned trial defence can defeat an appeal.
What this practically means
#Executive summary
#Key legal issues
#Sufficiency of evidence of identification where the appellant was a stranger to the witnesses, the incident occurred at night, and identification in the parade took place three months later
The totality of the circumstances - bright electric lighting from an estimated 20 bulbs, close proximity (2-4 metres), duration of 4-5 minutes, prompt descriptions given to police the following day, and independent identification in the parade - made the identification safe and positive
The court re-evaluated the entire evidence as a first appellate court. It found that the lighting, distance, duration of the incident, prior descriptions given to police and subsequent identification parade gave the witnesses opportunity to form a permanent impression of the appellant. PW3 had extra reason to be keen since the deceased was his father. The trial judge's assessment of witness credibility was entitled to weight.
Whether a challenge to the regularity of the identification parade could be entertained on first appeal
No - the complaint of an irregular parade was raised for the first time on appeal and was therefore incompetent
Relying on Japheth Mwambire Mbitha vs. R, the court held that only issues raised and determined by the trial court or on first appeal can be pursued on appeal. Since the appellant had not challenged the parade in the trial court, the contention was barred.
Whether the appellant's alibi defence created doubt in the prosecution case
The alibi was properly considered and rejected as the prosecution evidence squarely placed the appellant at the scene
The appellant claimed to have been at home from 5pm, corroborated by his wife, but the court found that the prosecution evidence of identification placed him at the scene on the material night, so the alibi did not raise a reasonable doubt.
Whether malice aforethought was proved
Yes, the medical report on the cause of death established an intention to kill
The court found that the shooting of the deceased in the head without provocation or reflection, evidenced by the autopsy report, demonstrated the requisite malice aforethought for murder under section 203 of the Penal Code.
Legal principles established
#- On a first appeal, the Court of Appeal must subject the entire evidence to a fresh examination and reach its own conclusions, while making allowance for the trial court's advantage of seeing and hearing the witnesses.
- Issues not raised and determined by the trial court or on first appeal cannot be raised for the first time on a first or second appeal.
- The prosecution is required to avail only those witnesses whose testimony is relevant to the matter under inquiry, and there is no legal requirement on the number of witnesses needed to prove a fact.
Court orders
