Kenga Kaingu Mweni & 2 others v Republic
The bottom line
#Kenya's Court of Appeal quashed murder convictions because the trial judge failed to interpret witness testimony and properly guide assessors, freeing the appellants.
What this practically means
#Executive summary
#Key legal issues
#Failure to interpret witness evidence into English
The failure to interpret the Swahili evidence of key eyewitnesses, and the unexplained handling of a Duruma-speaking witness, rendered their evidence worthless and the trial defective.
English is the official language of the High Court under section 198 of the Criminal Procedure Code. The evidence of the first and third prosecution witnesses, the daughter-in-law and granddaughter of the deceased, was given in Swahili without interpretation; the judge only noted 'Sworn interpreter made available' over a month later. The record also contained incomplete and meaningless passages attributable to the judge. These defects destroyed the evidentiary foundation of the murder convictions.
Disqualification of a defence witness
Disqualifying a defence witness merely because he was seated in court during prosecution evidence was impermissible and an irregularity rendering the trial a nullity.
The judge disqualified DW4, Chengo, simply because he had been seated in court while prosecution evidence was given. The court held that a prospective witness's presence in court affects only the credibility or weight of his evidence, and does not justify barring him from testifying, especially for the defence. This illegal disqualification was singled out as an irregularity making a retrial unjust.
Summing up to assessors
The judge's one-sided 'summary of the case' was no summing-up at all; the failure to guide lay assessors on the law, including the burden of proof beyond reasonable doubt, made the trial fatally defective.
Section 322(1) of the Criminal Procedure Code does not impose a mandatory duty to sum up, but authority establishes that assessors, being laymen, require the judge's guidance on legal issues, especially in murder trials. The judge neither explained the law of murder nor instructed the assessors on the standard of proof, and her summary was one-sided. Section 262, requiring trials before the High Court to be with the aid of assessors, was rendered nugatory.
Whether a retrial should be ordered
No retrial was ordered because the illegal disqualification of the defence witness and the cumulative irregularities would make a second trial unjust.
The respondent sought a retrial. Applying the principles in Kungu's case, the court noted that where an accused was denied the opportunity to call a material witness in the defective trial, ordering a retrial would subject him to a second trial that could have been avoided. The disqualification of Juma was precisely such a deprivation, and the cumulative effect of the irregularities reinforced the conclusion that a retrial would be unjust.
Legal principles established
#- Although section 322(1) of the Criminal Procedure Code does not impose a mandatory duty to sum up, good sense and authority require a summing-up to lay assessors, particularly in murder trials; failure to sum up renders the proceedings fatally defective.
- The practice of summing-up to assessors has acquired the force of law.
- A prospective defence witness who has been seated in court during prosecution evidence may not be disqualified on that ground; it goes only to credibility or weight.
- A retrial will not be ordered where the accused was deprived of calling a material witness during the defective trial, as that would subject him to a second trial that could have been avoided.
- Justice must be administered according to law, not according to the whims or caprices of a judicial officer.
