Key legal issues
#Scope of second appellate jurisdiction
The Court's jurisdiction is limited to matters of law under Section 361 of the Criminal Procedure Code; fact findings of the two courts below are not interfered with absent demonstration of error in law.
Relying on Hamisi Mbela Davis and Erick Onyango Ondeng', the Court held that a second appellate court defers to concurrent fact findings because it did not see or hear the witnesses. Interference lies only where the courts below considered matters they should not have, omitted matters they should have, or were plainly wrong, which would amount to error of law.
Proof of penetration and effect of medical evidence
The fact of a sexual offence need not always be proved by medical examination; the victim's truthful evidence under Section 124 of the Evidence Act, together with circumstantial evidence, suffices.
PW1's hymen was absent and PW1 awoke naked with pain, corroborating penetration. Although she had prior sexual relations, Section 124 permits conviction on the victim's credible evidence alone. Citing Kassim Ali and Arthur Mshila Manga, the Court found the medical evidence did not negate defilement and declined to disturb concurrent findings.
Effect of contradictions in witness testimony
Minor inconsistencies in human recollection are inevitable and do not vitiate the prosecution case unless they are major, substantial and fundamental so as to raise doubt as to guilt.
Applying John Nyaga Njuki, the Court held the alleged contradiction in PW1's evidence (waking naked versus having clothes on) was of a minor nature and did not affect the otherwise proved case, so the Court was entitled to overlook it and uphold conviction.
Constitutionality of minimum mandatory sentence and severity
The 15-year minimum sentence under Section 8(4) of the Sexual Offences Act remains lawful per the Supreme Court's direction in Republic v Mwangi; severity of sentence is a question of fact outside the second appeal remit.
Following Octavious Waweru Kibugi, the Court held that minimum mandatory sentences under the Sexual Offences Act remain valid until the Supreme Court determines otherwise on proper escalation. By dint of Section 361(2) of the Criminal Procedure Code, severity of sentence is a question of fact and the appellant showed no error in the exercise of the trial court's sentencing discretion.
Legal principles established
#- On a second appeal the Court is confined to matters of law and will not interfere with concurrent findings of fact of the two courts below unless none reasonable tribunal could have reached them or the courts below were plainly wrong.
- Minor discrepancies in witness testimony do not vitiate a prosecution case unless they are major, substantial and fundamental so as to create doubt as to the guilt of the accused.
- Minimum mandatory sentences under the Sexual Offences Act remain lawful following the Supreme Court's decision in Republic v Mwangi; ISLA & 3 others (Amicus Curiae), and severity of sentence is a question of fact outside second appellate remit.

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.
By parity of reasoning, we find that this appeal is devoid of merit and we dismiss it in its entirety.
In the circumstances, we find no reason to interfere with the concurrent findings of the two courts below. We therefore find that the appellant’s conviction was safe.
The fact of a sexual ofience need not be proved at all times by medical examination. The oral evidence and the circumstantial evidence are enough.
the minimum mandatory sentences under the Sexual Offences Act remain lawful until determined otherwise by the Supreme Court when the matter is properly escalated to that Court.
Orders accordingly.
Issues in the judgment
#The charge alleges offences on diverse dates between 28th March 2017 and 9th April 2017, but counsel for the respondent referred to the introduction of PW1 to the appellant on 'the night of 18th March 2017', a date outside the charge period.
PW6's testimony that the appellant had sex with the other lady because PW1 was on her menstrual cycle and only touched PW1's breasts is not reconciled in the judgment with the finding of penetrative defilement on the first occasion.
