Bkw v Republic
The bottom line
#Kenya's Court of Appeal upheld a man's defilement conviction and 20-year sentence, confirming that second appeals can only challenge legal errors, not facts.
What this practically means
#Executive summary
#Key legal issues
#Proof of the complainant's age without a birth certificate or age assessment report
Age was sufficiently proved by the consistent testimony of PW1, her parents and the medical evidence, plus the probation officer's report placing her birth in 2000, aligning with her being 14 at the time of the offence
The Court reiterated that age may be established by documentary evidence, oral testimony of the victim or a parent, medical evidence, or observation, provided the proof is credible and reliable. On the record, four witnesses and the probation officer's report consistently placed the complainant's age at 14 years, mathematically consistent with the offence date, so the ground failed.
Proof of penetration
Penetration was proved by the complainant's testimony corroborated by medical evidence of lacerations, a broken hymen and presence of spermatozoa; the slightest insertion suffices and an intact hymen is not required
PW1 gave a clear account of the assault, describing the appellant forcing himself on her and putting something into her vagina, causing pain and bleeding. The doctor's evidence confirmed physical trauma and spermatozoa. Applying Mark Oiruri Mose and George Owiti Raya, partial or slightest penetration suffices, so the contention that penile insertion was not proved failed.
Identification of the perpetrator
This was identification by recognition: the appellant was PW1's aunt's son, known to her and entrusted by her father to escort her home, and PW1's prompt, unshaken testimony placed him at the scene
The appellant was not a stranger to the complainant. She identified him as her aunt's son and her assailant; PW3 and PW4 confirmed prior escort occasions. Relying on Anjononi v Republic, recognition of a known assailant is more reliable than identification of a stranger, and the surrounding circumstances corroborated PW1's account.
Lawfulness of the 20-year sentence
The sentence was the prescribed statutory minimum under section 8(3) of the Sexual Offences Act; sentencing being a matter of fact under section 361, the Court had no basis to interfere
Having been convicted of defilement of a 14-year-old, the appellant attracted the prescribed 20-year sentence. Neither the trial court nor the High Court could have imposed any other sentence, and as sentencing is a matter of fact on second appeal, the Court could not disturb it.
New grounds raised for the first time on second appeal (defective charge sheet, inconsistencies, failure to call witnesses)
Those grounds were not raised before the first appellate court, are matters of fact, and cannot be entertained on a second appeal
Grounds including the defective charge sheet, evidential inconsistencies and failure to call witnesses were not raised in the first appellate court and were not considered by the courts below. They are matters of fact outside the Court's section 361 mandate and were therefore excluded from determination.
Legal principles established
#- On a second appeal the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact of the two courts below unless based on no evidence
- Matters not raised in the courts below cannot be raised for the first time on a second appeal
- The age of a complainant in a defilement case may be proved by documentary evidence, oral testimony of the child, parents or guardian, medical evidence or other credible forms of proof, which must be credible and reliable
- Penetration in defilement is proved by even the slightest insertion of the male genital organ into the female genital organ
- Recognition of an assailant known to the witness is more satisfactory and reliable than identification of a stranger
