Peter v Republic (Criminal Appeal E040 of 2024) [2026] KEHC 7836 (KLR) (4 June 2026) (Judgment) Neutral citation: [2026] KEHC 7836 (KLR) Republic of Kenya In the High Court at Machakos Criminal Appeal E040 of 2024 AN Ongeri, J June 4, 2026 Between John Muvia Peter Appellant and Republic Respondent (Being an appeal from the conviction and judgment of Hon MA OTINDO (PM) in Machakos SO CR CASE NO 45 of 2019 delivered on 25/4/2024) Judgment 1.​The Appellant was sentenced to 15 years imprisonment for the offence of defilement c/s 8(1) as read with section 8(4) of the SOA Act NO 3 of 2006. 2.​The particulars of the charge were that on 26/8/2019 at [Particulars Withheld] in Machakos County the Appellant intentionally and unlawfully caused his penis to penetrate the vagina of PNN, a child aged 17 years. 3.The Appellant was faced with an alternative charge of Indecent Act c/s 11(1) of the SOA NO 3 of 2006 in that on the same date and particulars as in count 1 above, the Appellant intentionally and unlawfully touched the vagina of PNN a child aged 17 years with his penis. 4.The Appellant pleaded not guilty and the prosecution called a total of six (6) witnesses. 5.​The prosecution evidence in summary was that the complainant who testified as PW1 said she went to the house of the Appellant who was her boyfriend on 25/8/2019 and she spent the night there. 6.​The following day she went home but did not enter the house as she saw her father outside the house. 7.​She went back to the Appellant's house until 28/8/2019 when her parents went with the chief (PW3) to the Appellant's house to get her. 8.The Appellant was arrested and detained at Likia (Tikia) Police Station while the complainant was taken to hospital. 9.PW5 Dr John Mutunga who testified on behalf of the doctor who examined the complainant said the complainant had a broken hymen. 10.The Appellant said he was at his home when he saw the complainant sitting by the roadside.He said the complainant called him and told him she had been chased from home and sought his assistance. 11.​He refused to help her and she followed him to his home and entered his house by force. 12.​Later on 23/4/2019 he was arrested by some people who went to his home and told him that he had defiled a child. 13.​The trial court found the Appellant guilty as charged and sentenced him to 15 years imprisonment. 14.The Appellant has appealed against both conviction and sentence on the following grounds;i.That the evidence adduced by the prosecution witnesses was not sufficient to even warrant even a case to answer.ii.That the witnesses who gave evidence before the court were compromised including alleging that the appellant (accused) was a close friend of the accused.iii.The medical evidence adduced was wanting and nothing was evident that it was the accused who committed the offence (if any was).iv.That the investigating officer failed to adduce evidence enough to show that the accused could have been a perpetrator of the offence (if any was committed).v.That the learned magistrate erred in not observing all aspects in relation to sexual offence act before convicting the accused.vi.The learned magistrate erred in law and fact for not considering the probation report considering the probation report considering the victim was aged 17 years at the time of the complaint. 15.​The parties filed written submissions as follows; The appellant, John Muija Peter, submitted that he was convicted with the offence of defilement contrary to section 8(1) as read with section 8(4) of the Sexual Offences Act and sentenced to fifteen years imprisonment. 16.He challenges both the conviction and sentence on grounds that the prosecution failed to prove its case beyond a reasonable doubt. 17.Regarding the complainant’s age, the appellant argues it was not properly established because the birth certificate was ambiguous and lacked a clear date of birth and that the mother merely stated the complainant was born in 2002 without giving an exact date, and the complainant herself admitted she was unsure of her birthday. 18.He submits that no age assessment was ordered, and the inconsistencies in the documentary evidence should have created reasonable doubt. 19.On penetration, the appellant points to the complainant’s own testimony, which he says is unreliable and contradictory was that she willingly spent multiple nights at his house, had been his girlfriend for two years, went to church alone for an entire day, and repeatedly chose not to go home. 20.He argues her behaviour suggested she was acting as an adult, not a child in need of protection, and that the medical evidence did not prove penetration because a broken hymen can result from many non-sexual causes. 21.He also contends the medical report was improperly produced by a doctor who was not its author, without proper justification or compliance with the Evidence Act, violating his right to challenge expert evidence. 22.Further, the appellant asserts the trial was procedurally flawed because he was denied a copy of the trial proceedings despite repeated requests, which he says breached his constitutional right to a fair hearing under Article 50(5)(b). 23.He maintains that his sworn defence, in which he explained that the girl followed him and he tried to send her away, was ignored by the trial court. 24.Citing several appellate decisions, he argues that the prosecution’s case was riddled with contradictions, that the complainant was not a credible witness, and that the defence of mistaken belief as to the complainant’s age under section 8(5) of the Sexual Offences Act should have been considered. 25.He concludes that the conviction is unsafe and prays that the appeal be allowed, the conviction quashed, the sentence set aside, and that he be set at liberty. 26.The Respondent, the Republic, filed written arguments opposing the appeal by John Muia Peter against his conviction and sentence from May 23, 2024, in Machakos Chief Magistrate’s Court Sexual Offences Case No. 45 of 2019. 27.The appellant was convicted of defilement and sentenced to 15 years in prison, with an alternative charge of committing an indecent act with a child. 28.The prosecution argues the conviction was sound because it proved all three legal ingredients beyond reasonable doubt: penetration, age, and identification. 29.Penetration was established by the complainant’s testimony that she stayed at the appellant’s house for several days and had sexual intercourse with him. 30.A doctor’s medical examination corroborated this, finding the victim’s hymen broken, with no bruises consistent with the non-forced nature of the encounter. 31.The victim’s age was proved by a birth certificate showing she was born on August 24, 2002, making her 17 years old at the time of the offense in late August 2019, legally a child. 32.Identification was reliable because the appellant was the complainant’s boyfriend who had promised to marry her, the victim’s mother testified she knew him, and he was arrested inside his own house where the complainant was found. 33.The trial court properly dismissed the appellant’s defense as untruthful and lacking credibility, especially since he did not deny being found with the complainant in his house. 34.The 15-year sentence is lawful, appropriate, and aligns with the Sexual Offences Act’s deterrent purpose. 35.The issues for determination in this appeal are as follows;i.Whether the prosecution proved the age of the complainant beyond a reasonable doubt;ii.Whether the act of penetration was proved to the required standard;iii.Whether the appellant was positively identified as the perpetrator of the offence;iv.Whether the appellant's defence, including a possible mistaken belief as to the complainant's age under Section 8(5) of the Sexual Offences Act, was properly considered by the trial court; andv.Whether the sentence imposed was legal and appropriate, particularly with regard to the period spent in pre-trial custody. 36.On the first issue of whether the prosecution proved the complainant’s age beyond a reasonable doubt, the appellant argues that the evidence was ambiguous because the birth certificate lacked an exact date of birth, the mother only stated a birth year of 2002, and the complainant herself was uncertain of her birthday. 37.The law is clear that in sexual offences involving minors, the burden of proving that the victim is a child under eighteen years rests entirely on the prosecution, and the standard of proof remains beyond a reasonable doubt. 38.The best proof of age is a certified birth certificate as provided under Section 41 of the Births and Deaths Registration Act, Cap 149. In this instance, the prosecution presented a birth certificate explicitly establishing the victim’s date of birth as August 24, 2002. 39.This document constitutes primary evidence of age, and the mother's general recollection or the complainant's own subjective uncertainty cannot invalidate the official records. 40.At the time of the offence on August 26, 2019, the complainant was legally seventeen years and two days old. 41.Consequently, the prosecution successfully discharged its burden of proving she was a child within the meaning of the Sexual Offences Act No. 3 of 2006, and the trial court did not err on this point. 42.Regarding the second issue of whether penetration was proved to the required legal standard, the appellant claims the evidence was unreliable, citing that the complainant stayed voluntarily at his house as his girlfriend and that the medical evidence of a broken hymen is inconclusive since it can happen through non-sexual activities. 43.Under Section 2 of the Sexual Offences Act, penetration is defined as the introduction of any part of the body or an object into the genital organs of another, and the slightest degree of penetration is sufficient to constitute the offence. 44.The complainant’s direct testimony that she stayed at the appellant's house and had sexual intercourse with him establishes the physical act. 45.Her testimony is robustly supported by the expert evidence of PW5, Dr. John Mutunga, who testified that the victim had a ruptured hymen. 46.While a ruptured hymen on its own may sometimes be attributed to non-sexual trauma, when it is coupled with the consistent, direct testimony of the complainant pointing to sexual intercourse, it serves as potent corroborative evidence. 47.The consensual or non-forced nature of the encounter, as highlighted by the lack of bodily bruises, does not absolve the appellant because Section 8 of the Sexual Offences Act creates a strict liability offence where the consent of a minor is entirely immaterial and cannot be used as a legal defence. 48.The third issue addresses whether the appellant was positively identified as the perpetrator. 49.The appellant’s defence asserts that the evidence failed to link him to the crime. 50.However, this is a case of recognition rather than identification of a stranger under difficult circumstances. 51.The appellant and the complainant had a long-standing romantic relationship spanning two years, the complainant's mother knew him, and the local chief, PW3, accompanied the parents to the appellant's own house where the complainant was actively found residing. 52.The appellant did not deny that the complainant was found inside his house. There was absolutely no room for mistaken identity, and the prosecution proved his connection to the locus and the victim beyond any doubt. 53.On the fourth issue concerning the appellant's defence and a possible mistaken belief as to the complainant's age under Section 8(5) of the Sexual Offences Act, the appellant contends that the girl acted like an adult and that his statutory defence was completely ignored. 54.Section 8(5) allows for a defence if the accused can prove that the child actively deceived them into believing they were over eighteen years old and that the accused reasonably held that belief based on deliberate steps taken to verify the age. 55.The statutory burden to prove this deception shifts to the defence on a balance of probabilities. 56.The record shows that the appellant did not adduce any evidence showing an active ploy or misrepresentation by the complainant regarding her age, nor did he demonstrate any steps he took to verify her status. 57.His sworn defence was a simple denial of the sexual encounter, claiming she forced her way into his house and that he tried to turn her away, which completely contradicts the premise of a mistaken belief during a consensual relationship. 58.The trial magistrate was fully justified in dismissing his defence as an afterthought that was entirely incompatible with the surrounding facts. 59.Finally, the fifth issue handles the legality and appropriateness of the 15-year imprisonment sentence. The appellant was sentenced under Section 8(4) of the Sexual Offences Act, which provides that a person who defiles a child between the ages of sixteen and eighteen years is liable to imprisonment for a term of not less than fifteen years. 60.Following the Supreme Court of Kenya decision in Francis Karioko Muruatetu & Another v. Republic (2017) eKLR, and subsequent clarifications regarding mandatory minimum sentences in sexual offences, the legal position in kenya is that the Muruatetu case(supra) is not applicable to sexual offences. 61.However, Section 333(2) of the Criminal Procedure Code mandates that a court must take into account the period an accused person spent in pre-trial custody before sentencing. 62.The record indicates that the appellant was arrested in 2019 and sentenced in 2024, but he was admitted to bond during the pre-trial period from 30th September 2019. 63.Accordingly, while the conviction for the offence of defilement contrary to Section 8(1) as read with Section 8(4) of the Sexual Offences Act is perfectly safe and is hereby upheld, the sentence of 15 years imprisonment is also lawful and appropriate in the circumstances of this case. 64.The sentence shall run from the date of the trial court’s judgment, being 25th April 2024, noting that the appellant was on bond during the pre-trial period and the period he stayed in custody from 9/9/2019 t0 30/9/2019 can be deducted from the 15 years during computation. 65.Orders shall issue accordingly.
