Key legal issues
#Compliance with Section 169(1) Criminal Procedure Code
Both the trial magistrate and the first appellate Judge fully complied with Section 169(1); their judgments were unassailable on that aspect.
The court examined the first appellate judgment and found it set out the offences, submissions, evidence, issues, applicable law and reasoned conclusions, satisfying the requirement that a judgment contain the points for determination, the decision thereon and reasons for the decision.
Voir dire non-recording
Failure to record the questions and answers during voir dire was not per se fatal; no prejudice or miscarriage of justice was occasioned.
Relying on Mohamed v Republic, DWM v Republic and Kathurima, the court held that recording in question-and-answer form is desirable but not mandatory; what matters is demonstration on the record that the trial court conducted the exercise and formed the requisite opinion of the minors' intelligence and understanding of the duty to speak the truth.
Burden of proof and defence
No burden was shifted to the appellant; both courts considered and rejected his grudge/fabrication defence.
Applying Sekitoleko and Ajwang, the burden remains on the prosecution throughout. The record showed both courts weighed the appellant's sworn defence against the prosecution evidence and gave reasons for rejecting it; the disbelief of the grudge allegation was a factual conclusion not re-examinable on second appeal.
Failure to call the father of PW1
Failure to call the father of PW1 was not fatal; he was not the prime mover of the prosecution.
Applying Bukenya and Keter, the prosecution need only call witnesses sufficient to establish the charge. PW4 set the prosecution in motion; the father's role was limited to accompanying the minors to the police and hospital, so his exclusion occasioned no prejudice.
Proof of age
Age was properly proved by the oral testimony of close relatives (PW3 and PW6) confirmed by medical assessment (PW5); birth certificates were not indispensable.
Following Basil Okaroni, Kaingu and Francis Omuromi, age may be proved by medical evidence, birth certificate, parents or guardian, and observation; the two methods used here were accepted by both courts below and aligned with approved principles.
Proof of penetration
Penetration was proved; the intact hymen and absence of discharge were consistent with interrupted complete penetration, and partial penetration sufficed.
The court adopted the Sexual Offences Act definitions, holding that the struggle by PW1 and PW2's escape may have interrupted complete penetration, explaining the intact hymen; the offence was complete on partial penetration. For PW2, digital contact completed the indecent act notwithstanding absence of injury.
Sentence of life imprisonment
The words 'liable to imprisonment for life' conferred discretion; the maximum sentence on a first offender without justification was erroneous; life imprisonment set aside and sixteen years substituted.
Applying Kichanjele, Opoya and Kogo, 'shall be liable to' expresses a maximum, not a mandatory sentence. Both courts below erred in treating the maximum as the only option; the appellant was a first offender and the prosecution advanced no reasons justifying the maximum sentence.
Legal principles established
#- On a second appeal the Court of Appeal is confined to matters of law and will not disturb concurrent findings of fact unless based on no evidence, a misapprehension of the evidence, or wrong principles
- The words 'shall be liable to' in a penal provision express a maximum penalty and leave the court discretion to impose a lesser sentence
- Failure to record verbatim the questions and answers in a voir dire examination of a minor is not per se fatal to the prosecution case if the record shows the court conducted the exercise
- The definitions of penetration, indecent act and defilement in the Sexual Offences Act apply to sexual offences whether charged under the Penal Code or the Sexual Offences Act
- Partial penetration is sufficient to complete the offence of defilement
Court orders
#- 1.Sentence of imprisonment for life with hard labour on count 1 set aside and substituted with a sentence of sixteen years imprisonment with hard labour to run concurrently with the sentence on count 2 from the date of conviction by the trial court
- 2.Appeal allowed only to the extent of the sentence; otherwise dismissed
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Nyeri
- H.C.CR. A. No. 21 of 2005
- Jurisdiction invoked
- Section 361(1) of the Criminal Procedure Code (second appeal on matters of law only)
Relief refused
#Quashing of the convictions on both counts
Concurrent findings of fact were supported by evidence; prosecution case proved beyond reasonable doubt
Costs
No costs order 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.
We must therefore interfere with the sentence of imprisonment for life with hard labour which we set aside and substitute therefor a sentence of sixteen years imprisonment with hard labour to run concurrently with the sentence on count 2 from the date of conviction by the trial court. To this extend only does the appeal succeed but is otherwise dismissed.
Our mandate which is as set out in Section 361(1) of the Criminal Procedure Code is that we are restricted to the addressing ourselves to matters of law only.
the use of the words "shall be liable to" does not import that the sentence mentioned in any particular section in which these words occur is merely a maximum and that the court may impose any lesser sentence below the limit indicated.
The offence was however complete upon partial penetration as defined above.
The prosecution is not obligated to call a superfluity of witnesses, but only such witnesses as are sufficient to establish the charge beyond any reasonable doubt.
An invitation to this court to depart from concurrent findings of fact by the trial and first appellate court should be declined by the second appellate court, unless it is shown that there are compelling reasons for doing so
Issues in the judgment
#Date of High Court judgment stated inconsistently as 28 October 2014 in the header and 28 November 2014 in the body
Coram initials (WAKI, NAMBUYE, AZANGALALA) differ from signature block initials (P.N. WAKI, R.N. NAMBUYE, F. AZANGALALA)
Quoted Section 145(1) of the Penal Code refers to girls under fourteen years although the charge and amended provision refer to under sixteen years
