BNT v Republic (Criminal Appeal 179 of 2019) [2025] KECA 643 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed that DNA evidence is not required to convict someone of defilement, and upheld a life sentence.
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 charge sheet was fatally defective in citing 'section 8(1)(2)' of the Sexual Offences Act
- 2.Whether the prosecution proved the ingredients of defilement (age, penetration, identity) beyond reasonable doubt
- 3.Whether the appellant's alibi defence was properly considered and displaced
- 4.Whether the absence of DNA evidence rendered the conviction unsafe
- 5.Whether the prosecution's failure to call Ronald Keya as a vital witness drew an adverse inference
- 6.Whether the alleged failure to assign counsel violated the appellant's constitutional rights
Key legal issues
#Defective charge sheet
The error of citing a non-existent 'section 8(1)(2)' was a minimal, harmless defect curable under section 382 of the Criminal Procedure Code
There is no section 8(1)(2) in the Sexual Offences Act, but the appellant raised the complaint for the first time on second appeal, indicating no prejudice and bereaving the Court of jurisdiction. Substantively, the charge gave clear notice of the offence and the age of the complainant, so no failure of justice resulted.
Proof of defilement
The prosecution proved age, penetration and identity beyond reasonable doubt; the complainant's age was established by age assessment and oral testimony
The age assessment report placed the complainant at 6-7 years. Penetration was proved by the complainant's consistent oral evidence corroborated by medical evidence showing a torn hymen, vaginal tear and extensive injuries requiring surgery. Identity rested on recognition evidence, which is more reliable than identification of a stranger.
Minor discrepancies in prosecution evidence
The discrepancies relied on by the appellant did not go to the root of the offence or weaken the prosecution case
The variations in the complainant's age, the mention of Ronald Keya, and PW4's reference to another girl were minor and did not affect the substance of the prosecution case. Concurrent findings that the complainant's evidence was cogent and reliable were not disturbed on second appeal.
Alibi defence
The alibi, raised for the first time on the witness stand without notice, was properly rejected as an afterthought
While the accused bears no burden of proving an alibi and the prosecution must displace it, late disclosure deprives the police of the chance to investigate. The strong recognition evidence eliminated any reasonable possibility that the alibi was true.
Legal principles established
#- An appellate court will not normally interfere with concurrent findings of fact by the two courts below unless they are based on no evidence, a misapprehension of the evidence, or wrong principles
- A defective charge sheet entitles an appellant to acquittal or retrial only where the defect caused prejudice; the test is substantive, not technical
- There is no mandatory requirement for DNA evidence to secure a conviction for sexual offences
- An accused person bears no burden of proving an alibi, but failure to disclose an alibi early enough may affect the weight given to it
Court orders
#- 1.The appeal fails in its entirety and is dismissed
- 2.The conviction and life sentence are affirmed
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya
- Appeal against conviction and sentence in Sexual Offence Case No. 94 of 2015 (Chief Magistrate's Court, Kakamega)
- Jurisdiction invoked
- Second appeal to the Court of Appeal under section 361(1) of the Criminal Procedure Code, limited to matters of law
Relief refused
#Acquittal on the ground of a defective charge sheet
The defect was minor and curable as a harmless error under section 382 of the Criminal Procedure Code
Acquittal for want of DNA evidence
There is no legal requirement for DNA tests to secure a conviction in sexual offences
Adverse inference against the prosecution for failing to call Ronald Keya
Ronald Keya was not a vital witness; the complainant never implicated him
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.
This is a second appeal. Our jurisdiction is, therefore, limited to a consideration of matters of law only by dint of section 361(1) of the Criminal Procedure Code.
There is no requirement under our law for the prosecution to present DNA tests linking an accused person to the crime in sexual ofiences, in order to secure a conviction.
The upshot is that the appeal fails in its entirety and is hereby dismissed.
we are satisfied that the conviction against the appellant was safe, and we afirm it.
An alibi raises a specific defence and an accused person who puts an alibi as an answer to a charge does not in law thereby assume any burden of proving that answer and its suficient if an alibi introduces into the mind of a court a doubt that is not unreasonable.
Issues in the judgment
#The judgment records the age assessment as finding the complainant 6-7 years old, while PW1's testimony that she was born in December 2009 is said to make her around five years old at the time of the incident, and the charge sheet alleged 8 years; the court treats all as consistent with being below twelve
