What this practically means
#Executive summary
#Questions the Court framed

- 1.Whether the case against the appellants was proved beyond reasonable doubt
- 2.Whether the appellants' defences were given due consideration
- 3.Whether the sentence imposed upon the appellants was deserved
Key legal issues
#Ingredients of gang defilement under section 10 of the Sexual Offences Act
Gang rape/defilement requires rape or defilement committed in association with others or in their company with common intention; presence with common intention suffices even without direct penetration by the accused
The Court construed section 10 and identified three ingredients: rape or defilement under the Act; commission in association with another or others; or presence in the company of others committing the offence with common intention. Common intention with the actual penetrators renders an accused as guilty as those who penetrated the victim.
Proof of age of the complainant
A birth certificate obtained after proceedings commenced still proves minority; what matters is proof at hearing that the victim was a minor at the time of the offence
The appellants argued the complainant's birth was registered only after the matter went to court. The Court held it immaterial when the certificate was obtained, so long as at the hearing it was proved that PW1 was a minor when the defilement was committed. The victim's truancy did not excuse the accused's conduct given the mandatory character of the provision.
Corroboration of a child victim's evidence
Under the proviso to section 124 of the Evidence Act, corroboration is unnecessary where the child victim of a sexual offence is truthful
The appellants contended PW1's evidence was uncorroborated. The Court held it is well settled that courts are not hamstrung by corroboration requirements where the victim is a child of tender years if the court is satisfied she is truthful; the trial court had found PW1 truthful. Credibility may be determined on demeanour.
Failure to call certain witnesses
The prosecution need not call a superfluity of witnesses; the choice of witnesses is within its discretion and reviewable only for oblique motive
The appellants complained that Whitney, the informer and the appellants' sister were not called. The Court found no evidence any would have given meaningful testimony, reiterated that no particular number of witnesses is required unless the law so provides, and that interference is warranted only where oblique motive is shown.
Enhancement above the prescribed minimum sentence
A sentence above the prescribed minimum must be justified by aggravating circumstances explained by the trial court; absent that, the enhancement is arbitrary
Section 10 prescribes a minimum of 15 years. The trial court imposed 20 years without identified aggravating circumstances. The Court held the accused is entitled to the least prescribed punishment and that any deviation from the minimum must be explained, failing which the enhancement is arbitrary. It substituted 15 years.
Legal principles established
#- A second appellate court considers only issues of law, not facts already considered by the two courts below
- Where a minimum sentence is prescribed, any deviation or enhancement must be explained by the trial court, otherwise the enhancement is arbitrary
- Under the proviso to section 124 of the Evidence Act, corroboration is not required where the victim of a sexual offence is a child of tender years if the court is satisfied the child is truthful
- The prosecution is not obliged to call a superfluity of witnesses; whether to call a witness is a matter within the prosecution's discretion, reviewable only for oblique motive
- For defilement under section 8 of the Sexual Offences Act, the prosecution must prove minority of the victim, penetration, and that the accused was the penetrator
- An accused present when a complainant is defiled, with common intention with the perpetrators, is equally guilty under section 10 of the Sexual Offences Act

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.
In the premises, while we dismiss the appellants' appeal on conviction, we set aside the sentence of 20 years' imprisonment imposed on them and substitute therefor a sentence of 15 years' imprisonment for each of the appellants.
Since the appellants were out on bond during the trial, the said sentences shall run from the date of their conviction by the trial court, on 15th May 2018.
Our duty as a second appellate court is to consider only issues of law as opposed to the facts which have been considered by the two courts below.
We hold that in cases where a minimum sentence is prescribed, any deviation therefrom ought to be explained by the trial court, otherwise the enhancement of the sentence would be arbitrary
the prosecution is not obligated to call a superfiuity of witnesses, but only such witnesses as are suficient to establish the charge beyond any reasonable doubt.
courts are not hamstrung by requirements of corroboration where the victim of a sexual ofience is a child of tender years, if it is satisfied that the child is truthful.
Issues in the judgment
#The judgment does not state the case number of the present appeal before the Court of Appeal; only the appeal below (Bungoma High Court Criminal Appeal Nos. 21 and 22 of 2018) is identified
The judgment recites the appeal from the trial as having been dismissed by the High Court without recording the date of that decision, and the trial conviction date is given as 18th May 2018 in one passage and 15th May 2018 in the final orders
