Republic v Mweni (Sexual Offence E038 of 2022) [2025] KEMC 277 (KLR)
The bottom line
#A Makindu court acquitted a man of defiling a four-year-old girl because investigators failed to prove he was the assailant beyond reasonable doubt.
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 complainant was defiled on 11/5/2022
- 2.If so, whether it was the accused person who defiled the complainant
- 3.If not, whether an indecent act was committed against the complainant on the aforementioned date
- 4.If so, whether such indecent act was committed by the accused person
- 5.Whether the prosecution has proven its case against the accused person to the required standard
Key legal issues
#Proof of age of the complainant
The complainant was a minor; proof need only show the victim was below eighteen, though it must be beyond reasonable doubt
The charge alleged the child was four years old. The health card produced showed birth on 14/10/2018, making her three years and seven months at the material time. Relying on Moses Nato Raphael and Kaingu Elias Kasono, the court held that contradictions on exact age are immaterial so long as minority below eighteen is established, age being relevant to sentencing categories.
Whether penetration was proved
Penetration was proved by the complainant's testimony corroborated by medical evidence, though the organ used was not established
The complainant testified she was touched and suffered pain; medical examination on 12/5/2022 revealed lacerations on the labia, foul-smelling discharge and a perforated hymen. Relying on Bassita Hussein and Fappyton Mutuku Ngui, the court accepted that medical evidence is not indispensable. The totality of evidence left no doubt the child was defiled, even though the instrument of penetration was unclear.
Reliability of unsworn testimony of a child of tender years without voire dire
Failure to conduct voire dire does not vitiate the trial; unsworn evidence falls under section 124 of the Evidence Act and must be treated with great caution
Citing Maripett Loonkomok, the court noted the 14-year threshold for voire dire and that mere absence of voire dire does not invalidate the trial. The proviso to section 124 permits conviction on the sole evidence of the victim if the court records reasons to be satisfied she is telling the truth; corroboration becomes paramount in exercising that power.
Positive identification of the assailant
Identification was not established with sufficient certainty; no inquiry was made into the circumstances of identification and the investigating officer was not called
Guided by Maitanyi, Wamunga and related authorities, the court warned itself of the danger of a single identifying witness. The circumstances of arrest were unclear, no one testified whether the name was given to police at first report, and the Assistant Chief was not called, leaving the possibility of mistaken identity unresolved.
The accused's medical condition defence
The defence of sexual incapacity failed because the accused bore the burden under section 111 of the Evidence Act and tendered no medical proof
Chronic urinary retention and catheter use were undisputed, but no medical evidence showed inability to erect or have intercourse. The court's own research indicated intercourse remains possible even with an indwelling catheter. The fact being especially within the accused's knowledge, he was discharged of no burden by mere assertion, and the defence was dismissed.
The defence of alibi and sufficiency of prosecution rebuttal
The alibi was probable and the prosecution failed to displace it, creating a reasonable doubt as to the accused's presence at the scene
The alibi was first raised at the defence hearing, but under Chabah, Kiarie and section 212 of the Criminal Procedure Code the prosecution could have sought to rebut it. The investigating officer was not called; evidence on the day-care arrangement and the accused's alleged presence at work was not investigated. His defence could not be disregarded.
Whether the case was proved beyond reasonable doubt
No; the evidence left only suspicion, which cannot ground a conviction
Applying the classic standard from Miller v Ministry of Pensions and Bakare v State, the court found it could not exclude that the assailant was someone else. Suspicion, however strong, cannot substitute for proof. The accused owes no duty to prove innocence, and the court was left gambling on probabilities, which is impermissible.
Legal principles established
#- Where an accused alleges a fact specially within his knowledge, such as a medical incapacity, the burden of proving it rests on him under section 111 of the Evidence Act
- An alibi need only introduce a reasonable doubt; the prosecution bears the duty of placing the accused at the scene and may be given an opportunity to rebut a defence raised for the first time
- A conviction cannot rest on suspicion; the prosecution must prove guilt beyond reasonable doubt
Court orders
#- 1.The accused person is found not guilty and acquitted of the offence of defilement contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act pursuant to section 215 of the Criminal Procedure Code
- 2.The accused person is equally acquitted of the alternative charge of committing an indecent act with a child contrary to section 11(1) of the Sexual Offences Act
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- First-instance criminal trial under the Sexual Offences Act and the Criminal Procedure Code
Relief refused
#Conviction on the main count of defilement
Proof beyond reasonable doubt was not attained; the alibi and gaps in investigation left a reasonable doubt as to the accused's presence at the scene and identity of the assailant
Conviction on the alternative count of committing an indecent act with a child
It suffers the same fate as the main count for the same reasons
Costs
No costs order made (criminal proceedings)
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.
Consequently, I hereby find the accused person not guilty and proceed to acquit him of the ofience of defilement contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act, pursuant to the provisions of section 215 of the Criminal Procedure Code.
For avoidance of doubt, the accused person is equally acquitted of the alternative charge. It is so decreed.
With the totality of the evidence on record, I find it dificult to disregard the defence evidence on what transpired on the material day. It cannot be ruled out that the accused person was not at home at the material time. His defence is probable.
I have a reasonable doubt, and this is a safeguard that has enormous value in our system.
Issues in the judgment
#Age discrepancies within the record: particulars state the complainant was aged 4 years while PW1 testified she was 3½ years old at the time of incident, and the health card indicates 3 years and 7 months; the court reconciled these rather than treating them as fatal
Date discrepancy in the evidence as recorded, corrected during trial
The judgment records that no voire dire examination was conducted although the court formed an opinion on the child's understanding of the oath
