(Being an appeal against the Judgement of Hon. Joy Ayieta (RM) in Madiany S.O CRC No. E11 OF 2025 delivered on 08.9.2025 and 02.10.2025 respectively)
1. The Appeal herein arises from the Judgement of Hon. Joy Ayieta (RM) in Madiany S.O CRC No. E11 OF 2025 dated 18.9.2025 wherein she convicted and sentenced the Appellant herein to 20 years’ imprisonment.
2. The Appellant was aggrieved and filed a Petition of Appeal dated 15 th October 2025 wherein he raised the following grounds of appeal;
I. THAT the learned trial magistrate erred in law and fact in not making a finding that the ingredients of the offence were not proved beyond a reasonable doubt.
II. THAT the learned trial magistrate erred in law and fact in not making a finding that the rights of the appellant to a fair trial were breached
III. THAT the learned trial magistrate erred in law and fact in not considering the procedural errors that were inconsequential to conviction.
IV. THAT the learned trial magistrate erred in law and fact in admitting evidence that was inadmissible.
V. THAT the learned trial magistrate erred in both law and fact in not weighing the conflicting evidences that were inconsequential to conviction.
The Appellant therefore prayed that the appeal be allowed and that the conviction be quashed and sentence set aside and he be set at liberty.
3. This being the first Appellate Court, the Court’s duty is to consider the evidence presented to the trial court and subject it to an independent analysis so as to arrive at its own conclusion. The court however will have to take into account that it neither heard nor saw the witnesses. In Okeno- Vs- Republic (1972) EA 32 it was held that;
‘‘"An appellant is entitled to expect the evidence as a whole to be submitted to a fresh and exhaustive examination and to the Appellate court's own decision on the evidence. The first appellate court must itself weigh conflicting evidence and draw its own conclusions. It is not the function of the first appellate court merely to scrutinize the evidence to see if there was some evidence to support the lower court's findings and conclusions; it must make its own findings and conclusions. Only then can it decide whether the magistrate's findings can be supported. In doing so, it should make an allowance for the fact that the trial court has had the advantage of hearing and seeing the witnesses"."
4. The case before the lower court is that the Appellant, Byron Owino Oyugi was charged before the Senior Principal Magistrate's Court at Madiany with the offence of defilement contrary to Section 8(1) as read with Section 8(3) of the Sexual Offences Act, No. 3 of 2006 . The particulars of the offence were that on diverse dates between 25th April 2025 and 29th April 2025, at Wera Village, Omia Mwalo Sub-Location Rarieda Sub County in Siaya County, intentionally caused his penis to penetrate the vagina of V.A.O , a child aged 13 years
5. The Appellant also faced an alternative charge of committing an indecent act with a child contrary to Section 11(1) of the Sexual Offences Act . The particulars were that on diverse dates between the dates of 25 th April 2025 to 21 st June 2025 in Wera village of Omia Mwalo sub location, Rarieda sub county in Siaya County at unknown time intentionally touched the vagina of V.A.O a child aged 13 years. The Appellant pleaded not guilty to both counts. After a full trial, the learned trial magistrate convicted him on the main count of defilement and sentenced him to serve twenty (20) years imprisonment. The same has precipitated into the present appeal.
6. PW1 V.A.O (The Complainant / Child Survivor) provided primary direct evidence of the defilement occurring between April 25th and April 29th, 2025. She detailed the locus in quo (the Appellant's house within their shared family homestead) and the precise mechanics of the offense stating that the Appellant forcefully pulled her into his room, locked the door, stripped her of her skirt and underpants and inserted his penis into her vagina. She testified that the Appellant is her uncle as he is a brother to her father. That her grandmother used to send her to take food to the Appellant who also lived within the same homestead and that on those occasions he would lock the door and proceed to remove her clothes and then insert his penis into her vagina. She explained her initial silence by indicating that she had a sore throat which was painful due to attending a church kesha (night vigil) the previous night which temporarily incapacitated her voice. She also cited a fear of being beaten by her mother. She testified to a later distinct incident on Saturday June 21st, 2025, where the Appellant chased her, dragged her near a toilet and touched her breasts an act which was interrupted by her mother.
On cross-examination, she stated that it was the Appellant who had defiled her and that her mother found the Appellant fondling her breasts.
7. M.A.O (PW2) was the mother of the complainant who testified that upon going to look for her daughter, she caught the Appellant in flagrant delicto embracing and inappropriately touching the minor’s breasts. She added that the moment the Appellant saw her, he fled the scene. That she chased after the Appellant as she raised alarm and later went back home and upon disciplining the minor for delaying, the child made an immediate, tearful disclosure that the Appellant had previously defiled her in the month of April 2025 and that she had been too terrified to speak about it. She produced the primary identification details confirming the minor’s date of birth as June 10th 2011 making her a child under Kenyan law. She identified the birth certificate as PMFi-1.
8. Ezekiel Kenga (PW3) testified that he is a clinical officer working at Ongido Sub County Hospital. That, he examined the minor on June 22 nd , 2025. That on examination, he noted no fresh external vaginal lacerations or active discharge. That he noticed two critical findings that legally established penetration inter alia; that the minor's hymen was completely broken ; that the minor tested positive for pregnancy (with a distended abdomen and a clinically assessed gestational period of approximately 8 weeks). He noted that the minor's history indicated her last sexual episode was with her uncle in April and that she had missed her menses ever since. He explicitly concluded that the pregnancy and clinical history conclusively confirmed that the complainant had been defiled. He produced the treatment notes and P3 for as exhibits 2 and 3 respectively. On cross-examination, he stated that the pregnancy was positive and which linked the Appellant to it as per the evidence of the minor.
9. No. 116890 PC Samuel Njoroge Mwangi (PW4) was the investigating officer who testified that he received the report on June 22nd, 2025 from the local village elder and the mother of the complainant. That he learnt that the Appellant and the complainant had been engaging in immoral activities. He also learnt that the Appellant had been defiling the minor between 25/4/2025 and 29/4/2025. That he placed the Appellant in custody as he arranged to have the minor taken to hospital for examination. That he secured the minor’s original birth certificate which he produced as PExh 1 which legally anchored her age at 13 years old.
10. The trial court later ruled that a prima facie case had been made out against the Appellant by the Respondent and that the Appellant was subsequently placed on his defence and who elected to tender an unsworn statement and called no witnesses.
11. Byron Owino Oyugi (DW1) was the Appellant who stated that he knew the complainant and further that he was aware of the charges facing him. He stated that he could not recall the events of April 2025 as he was in the lake but he remembers the one wherein the mother of the complainant found him with the minor wherein he stated: "Time passed and her mother found us standing on the path behind my grandmother's house. I saw PW2 and ran away."
12. When confronted with the substantive charge of defilement from April 2025, the Appellant stated: "I cannot remember what happened in April. On that day I was in the lake." He attempted to raise a vague, generic alibi (being a fisherman at the lake) but failed completely to provide specific dates, times or supporting witnesses to back it up.
13. The appeal was canvassed by way of written submissions. The Appellant complied while the Respondent did not.
14. The Appellant submitted that the prosecution bears the absolute burden of establishing its case beyond reasonable doubt by proving three cumulative ingredients of defilement: the age of the victim, the fact of penetration, and the positive identification of the accused. He argued that the prosecution failed to present cogent evidence to clear evidential gaps.
15. To fortify this argument, the Appellant relied on Bakare v. State (1987) 1 NWLR (Pt. 52) 579 : Where Oputa, JSC (Supreme Court of Nigeria) observed that the presumption of innocence requires a high degree of cogency in prosecution evidence to displace it stating that while absolute certainty is impossible, proof beyond reasonable doubt does not admit of plausible possibilities. He also relied on the case of Pius Arap Maina v. Republic (2013) eKLR where the Court of Appeal held that any evidential gaps in the prosecution's case which raise material doubts must invariably be resolved in favor of the accused person.
16. The Appellant further placed his reliance on sections 107(1), 108, and 109 of the Evidence Act (Cap 80, Laws of Kenya) t o assert that anyone who desires a court to give judgment on any liability dependent on facts must strictly prove that those facts exist.
17. While the Appellant did not dispute that the birth certificate indicated the victim's date of birth as 10th June 2011, he raised a material doubt regarding the identity and legitimate ownership of the document. He pointed out distinct discrepancies between the names used. The charge sheet listed the victim as V.A.O. , a minor aged 13 years. The prosecution at various intervals prior to the hearing used two different sets of initials namely V.A.O. and M.A.O. During the hearing, the minor testified using the initials V.A. The Appellant argued that " V.A. " is fundamentally different from " V.A.O. " creating an unresolved fatal defect regarding the victim’s true identity.
18. The Appellant forcefully contested the element of penetration, arguing that PW1 (the complainant) failed to demonstrate or specify how penetration occurred. He submitted that her testimony lacked the mandatory "sensory details" necessary to sustain a conviction based solely on a victim's word. In support of this position, the Appellant relied on the case of Julius Kioko Kivuva v. Republic (2015) eKLR : where the High Court held that evidence of sensory details such as what a victim heard, saw, felt or smelled is highly relevant and necessary to strengthen the credibility of a witness where a conviction rests primarily on the victim's testimony. The Appellant argued that PW1's reference to "tabia mbaya" did not equate to legal penetration.
19. The Appellant pointed out that the medical examination conducted by PW3 (pages 22–23 on the P3 Form) explicitly normalizes the physical anatomy of the victim. It recorded that the labia majora, labia minora, clitoris, peri-urethral area, vestibule and vagina were all normal with no lacerations or discharge thereby negating any medical proof of penetration under Section 2 of the Sexual Offences Act.
20. The Appellant acknowledged that he and the complainant were familiar with each other. However, he maintained that the prosecution failed to prove that he was the person who actually defiled her. Invoking Section 33 of the Sexual Offences Act, the Appellant argued that courts must critically analyze the surrounding circumstances of an alleged crime to deduce if it was likely to have been committed. He characterized the prosecution's case as reliant on weak circumstantial evidence noting that PW1 claimed she was pulled into a house but failed to establish penetration.
21. The Appellant relied on the jurisprudence in P.O.N v. Republic (2019) eKLR where the Court of Appeal ruled that to base a conviction entirely on circumstantial evidence, the inference of guilt must be the only rational inference to be drawn. If any reasonable possibility consistent with innocence exists, the accused must be acquitted. Also in Simon Musoke v. Republic (1958) EA 71 it was held that before drawing an inference of guilt from circumstantial evidence, a court must be absolutely sure that there are no co-existing factors that weaken or destroy that inference. Again in Absalom Amboka Okila v. Republic (2020) eKLR Matheka, J. observed that under Section 33 of the Sexual Offences Act, the circumstances under which an offence is alleged to have been committed cannot be ignored, as they serve as the vital fourth ingredient to determine the likelihood of the offense occurring.
22. Ultimately, the Appellant submitted that the trial court's decision was a product of speculation, contradictions, inconsistencies, and poor investigations. He prayed that the High Court orders inter alia; allow the appeal; quash the conviction; set aside the 20-year prison sentence and to set him at liberty.
23. I have considered the Appeal, the record of appeal and the Appellant’s submissions and find that the issue for determination is whether the prosecution proved its case against the Appellant beyond reasonable doubt.
24. It is trite that in criminal cases, the burden of proof is upon the prosecution to discharge and that the standard of proof is one of beyond any reasonable doubt. See Woolmington Vs Dpp [1935] AC 462.
25. It is noted that the Appellant had been charged with an offence of defilement under section 8(1) as read with section 8(3) of the Sexual Offences Act No. 3 of 2006. In order to prove the offence therein, the Respondent was under obligation to prove certain essential ingredients and that to answer this, the Court must evaluate the three canonical ingredients of defilement namely; the age of the complainant (whether she was a child under the law); the fact of penetration and the positive identification or recognition of the Appellant as the perpetrator. These ingredients must each be proven for a conviction to ensue (See George Opondo Olunga vs Republic [2016] eKLR)
26. S ection 8(1) of the Sexual Offences Act No. 3 of 2006 provides as follows: - (1) A person who commits an act which causes penetration with a child is guilty of an offence termed defilement.
(2) A person who commits an offence of defilement with a child aged eleven years or less shall upon conviction be sentenced to imprisonment for life.
(3) A person who commits an offence of defilement with a child between the age of twelve and fifteen years is liable upon conviction to imprisonment for a term of not less than twenty years.
(4) A person who commits an offence of defilement with a child between the age of sixteen and eighteen years is liable upon conviction to imprisonment for a term of not less than fifteen years.
(5) It is a defence to a charge under this section if
(a) it is proved that such child, deceived the accused person into believing that he or she was over the age of eighteen years at the time of the alleged commission of the offence; and
(b) the accused reasonably believed that the child was over the age of eighteen years.
(6) The belief referred to in subsection (5) (b) is to be determined having regard to all the circumstances, including any steps the accused person took to ascertain the age of the complainant.
(7) Where the person charged with an offence under this Act is below the age of eighteen years, the court may upon conviction, sentence the accused person in accordance with the provisions of the Borstal Institutions Act and the Children's Act.
(8) The provisions of subsection (5) shall not apply if the accused person is related to such child within the prohibited degrees."
27. As regards the age of the victim, it is noted that the same is crucial in that the eventual sentence to be imposed upon conviction is dependent upon the age of the victim.. The Court of Appeal in Edwin Nyambogo Onsongo vs. Republic (2016) eKLR stated as follows in respect of proving the age of a victim in cases of defilement:
“... the question of proof of age has finally been settled by recent decisions of this court to the effect that it can be proved by documents, evidence such as a birth certificate, baptism card or by oral evidence of the child if the child is sufficiently intelligent or the evidence of the parents or guardian or medical evidence, among other credible forms of proof. We think that what ought to be stressed is that whatever the nature of evidence preferred in proof of the victim’s age, it has to be credible and reliable.”
28. Regarding proof of age, and as noted above, it is noteworthy to state at the outset that the importance of proving the age of a victim in sexual offences is paramount considering that under the Sexual Offences Act, the prescribed sentence is determined by the age of the victim.
29. Section 2 of the Children’s Act defines a child as a person under the age of eighteen (18) years. There are various ways which can be used to prove a victim’s age as held in Mwalango Chichoro Mwajembe V Republic, Criminal Appeal No. 24 of 2015 (UR ) where the court stated as follows :
“……..the question of proof of age has finally been settled by a recent decisions of this court to the effect that it can be proved by documentary evidence such as a birth certificate, baptism card or by oral evidence of the child if the child is sufficiently intelligent or the evidence of the parents or guardian or medical evidence, among other credible forms of proof” It has even been held in a long line of decisions from the High Court that age can also be proved by observation and common sense. (See Denis Kinywa -Vs- Republic Criminal Appeal No. 19 of 2014) and (Omar Ucher -Vs- Republic Criminal Appeal No. 11 of 2015). We doubt if the courts are possessed of requisite expertise to assess age by merely observing the victim since in a criminal trial the threshold is beyond any reasonable doubt. This form of proof is a direct influence by the decisions of the Court of Appeal of Uganda in Francis Omuroni -Vs- Uganda Criminal Appeal No. 2 of 2000. We think that what ought to be stressed is that whatever the nature of evidence presented in proof of the victim’s age, it has to be credible and reliable...”
In the present case, the prosecution discharged this burden through the birth certificate (Exhibit 1) produced by PW4, which established that the minor was born on 10/6/2011, making her age as thirteen years at the time of the incident. This was further corroborated by the Clinical Officer (PW3), satisfying the legal threshold. The Appellant in his defence did not dispute the complainant’s age as per the birth certificate and further did not dispute the fact that the complainant was still a minor. I find that the age of the minor (13 years) was proved beyond reasonable doubt
30. As regards the aspect of penetration, section 2 of the Sexual Offences Act No.3 of 2006 defines ‘‘Penetration’’ as the partial or complete insertion of the genital organs of a person into genital organs of another person.
31. Penetration is proved through the evidence of the victim. The testimony of the victim in this case coupled with evidence from other witnesses was sufficient to determine whether penetration occurred. Under the provisions of section 124 of the Evidence Act, the same provides as follows:
"Notwithstanding the provisions of section 19 of the Oaths and Statutory Declaration Act, where the evidence of the victim admitted in accordance with that section on behalf of the Prosecution in the proceedings against any person for an offence, the accused shall not be liable to be convicted in proceedings against him unless it is corroborated by other evidence in support thereof implicating him. Provided that where in a criminal case involving a sexual offence, the only evidence is that of the alleged victim of the offense, the court shall receive the evidence of the alleged victim and proceed to convict the accused person, if for reasons to be recorded in the proceedings, the court is satisfied that the alleged victim is telling the truth."
In the case of Bassita vs. Uganda S.C. Criminal Appeal No. 35 of 1995 it was held thus:
"An intercourse or penetration may be proved by direct or circumstantial evidence. Ally the sexual intercourse is proved by the victim's own evidence and reinforced by the medical evidence or other evidence. Though desirable, it is not hard and fast rule that the victim's evidence and medical evidence must always be adduced in every case of defilement to prove sexual intercourse or penetration. Whatever evidence the prosecution may wish to adduce to prove its case such evidence must be such that is sufficient to prove the case beyond reasonable doubt."
32. The Appellant argues that penetration was not proven because the minor utilized the Swahili phrase "tabia mbaya" (bad behavior) and failed to provide deep sensory details of the act as required under Julius Kioko Kivuva v Republic [2015] eKLR. He further points to the P3 Form where the clinical officer ( PW3) noted that her external genitalia (labia majora, minora, and vestibule) were "normal" and free from fresh lacerations.
33. A holistic reading of the minor’s testimony shatters the Appellant’s line of reasoning. PW1 did not merely stop at "tabia mbaya" . She went on to state categorically “Accused took his penis and inserted in my vagina... Accused removed my skirt and underpants... Accused removed his briefs half way to his knees." This is direct, specific anatomical evidence of penetration as defined under Section 2 of the Sexual Offences Act. Furthermore, the lack of fresh lacerations or bleeding on her external genitalia is medically logical. The defilement occurred between 25th and 29th April 2025 . The medical examination by PW3 was performed on 22nd June 2025 nearly two months later. It is obvious that any superficial external injuries would have long healed. Further, and most damningly, PW3 testified that upon a per-vaginal examination, the minor's hymen was broken and that she tested positive for pregnancy. The clinical officer noted that the abdomen was distended with a growing foetus and that he confirmed the pregnancy was estimated at 8 weeks.
34. Kenyan courts have repeatedly held that a child’s testimony on penetration need not to be scientifically perfect as it conveys the fact of intrusion. In Mark Oiruri Mose v Republic [2013] eKLR , the Court of Appeal stressed that a victim account of how the male genitalia came in contact with her genital is sufficient to prove penetration
35. The minor testified that she had never had sexual intercourse with any other person and thus it was only the Appellant who was her uncle who had defiled her. I have no reason to doubt the testimony of the minor as nothing emerged that her family had any problems with the Appellant. In fact it came out clearly that the complainant was the one who was frequently used by the family to take meals to the Appellant who also lived within the homestead. Consequently, I find the element of penetration was proved beyond a shadow of doubt by the Respondent.
36. The Appellant contends in his submissions that there exists a material doubt regarding the identity of the complainant. He argues that while the charge sheet lists the victim as V.A.O , she gave her name as V.A in court, which creates a fatal discrepancy as to whether she is the legitimate owner of the birth certificate produced. This Court finds this argument to be a hyper-technical distraction devoid of legal merit. The minor ( PW1 ) testified that her name is V.A and that she was 13 years old. Her mother, Maureen Adhiambo Okoth ( PW2) explicitly testified that the minor was her daughter and was born on 10th June 2011. The investigating officer ( PW4) produced the minor's original birth certificate ( PExh 1 ) which verified her birth date as 10th June 2011. The certificate of birth indicated the name of the minor as .V.A. The evidence of the minor and her mother left no doubt that the two names refer to one and the same person and that the person examined by the clinical officer was V.A.O as captured on the P3 form and was the complainant. Again, the Appellant confirmed in his defence evidence that he knew the complainant very well. He was therefore not talking of a stranger but someone he had known quite well. I find the contention by the Appellant to be preposterous and devoid of any merit.
37. As regards the identity of the perpetrator, the complainant stated that the Appellant was well known to her as her uncle and brother to her father. She further confirmed that she used to be sent to the Appellant’s house to take food to him as he also lived within the same homestead. I find that the identification of the Appellant was firm, consistent and free from any possibility of mistake. The complainant knew the Appellant prior to the incident and positively recognized him as the perpetrator. This was therefore a case of recognition rather than identification of a stranger, which Kenyans courts have consistently held that to be the most reliable form of identification. In Anjononi & Others v Republic [1980] eKLR , the Court of Appeal held that recognition is ‘‘more reliable than identification of a stranger because it is based on the witness’s prior knowledge of the accused’’. The Complainant’s evidence was direct, unwavering and supported by circumstances of close physical proximity during the commission of the offence which left no room for doubt. Further, it is noted that the Appellant concedes in his submissions that he and the complainant are well known to each other. They reside within the same homestead. It emerged that the Appellant is the paternal uncle of the minor ( "a brother to my father" as PW1 testified). The offence took place at 1:00 p.m. in broad daylight inside the Appellant's house. This is an absolute case of recognition which minimizes the possibility of mistaken identity. It is further noted that the complainant’s mother found the Appellant in a compromising situation with her daughter, as he was then fondling her breasts and had enveloped her in a tight embrace (flagrant delicto) and that on seeing her, he took off and that she gave chase after him as she raised alarm. Furthermore, the narrative contains strong circumstantial and corroborative elements. On 21st June 2025, the minor’s mother ( PW2 ) caught the Appellant holding and embracing the minor on a path near a maize plantation at 7:00 p.m. Upon being spotted, the Appellant immediately took off and fled. In his own statutory defense the Appellant (DW1) admitted to this exact encounter:
"Time passed and her mother found us standing on the path behind my grandmother's house. I saw PW2 and ran away."
Under Section 8 of the Evidence Act (Cap 80), the conduct of an accused person during or after the alleged offence is highly relevant. The Appellant's flight upon being spotted with the minor is highly inconsistent with the behavior of an innocent uncle and strongly corroborates the minor's subsequent immediate disclosure to her mother that she had been defiled by him earlier between 25/4/2025 and 29/4/2025. Iam satisfied that the ingredient of identification was therefore sufficiently proved
27. 38. An analysis of the lower court record leaves no doubt that the learned trial magistrate carefully analyzed the evidence of the minor, the mother, the medical professional and the investigating officer. The defence raised by the Appellant was a mere bare denial coupled with a selective admission of the events of 21st June 2025. The Appellant offered no reasonable explanation as to why an innocent paternal uncle would flee into a maize plantation at night upon merely being seen with his niece by her mother. I find that the Respondent established all ingredients of the offence against the Appellant herein beyond any reasonable doubt. Hence, the finding on conviction by the trial court was quite sound and must be upheld.
39. On whether the sentence imposed upon the Appellant was appropriate, the statutory prescription and judicial discretion , the trial court imposed a sentence of twenty years’ imprisonment pursuant to Section 8(3) of the Sexual Offences Act, which prescribes this penalty for the defilement of a child aged between 12 to 15 years. While the Supreme Court in Francis Karioko Muruatetu & Another v Republic [2017] eKLR declared mandatory minimum sentences unconstitutional, it affirmed that courts must consider the gravity of the offense and the specific circumstances before sentencing. In Jared Koita Injiri v Republic [2019] eKLR , the Court of Appeal upheld a life sentence for defilement of a minor, noting that despite the discretion granted by Muruatetu , the severity of the crime against a child of tender years justifies the harshest penalty. The trial magistrate exercised this discretion, noting the mandatory nature of the provision and the need to deter such conduct.
40. In the case of Shadrack Kipkoech Kogo - vs - R. Eldoret Criminal Appeal No.253 of 2003 the Court of Appeal stated thus as regards interference with sentence: -
“sentence is essentially an exercise of discretion by the trial court and for this court to interfere it must be shown that in passing the sentence, the sentencing court took into account an irrelevant factor or that a wrong princ

1. The Appeal herein arises from the Judgement of Hon. Joy Ayieta (RM) in Madiany S.O CRC No. E11 OF 2025 dated 18.9.2025 wherein she convicted and sentenced the Appellant herein to 20 years’ imprisonment.
2. The Appellant was aggrieved and filed a Petition of Appeal dated 15 th October 2025 wherein he raised the following grounds of appeal;
I. THAT the learned trial magistrate erred in law and fact in not making a finding that the ingredients of the offence were not proved beyond a reasonable doubt.
II. THAT the learned trial magistrate erred in law and fact in not making a finding that the rights of the appellant to a fair trial were breached
III. THAT the learned trial magistrate erred in law and fact in not considering the procedural errors that were inconsequential to conviction.
IV. THAT the learned trial magistrate erred in law and fact in admitting evidence that was inadmissible.
V. THAT the learned trial magistrate erred in both law and fact in not weighing the conflicting evidences that were inconsequential to conviction.
The Appellant therefore prayed that the appeal be allowed and that the conviction be quashed and sentence set aside and he be set at liberty.
3. This being the first Appellate Court, the Court’s duty is to consider the evidence presented to the trial court and subject it to an independent analysis so as to arrive at its own conclusion. The court however will have to take into account that it neither heard nor saw the witnesses. In Okeno- Vs- Republic (1972) EA 32 it was held that;
‘‘"An appellant is entitled to expect the evidence as a whole to be submitted to a fresh and exhaustive examination and to the Appellate court's own decision on the evidence. The first appellate court must itself weigh conflicting evidence and draw its own conclusions. It is not the function of the first appellate court merely to scrutinize the evidence to see if there was some evidence to support the lower court's findings and conclusions; it must make its own findings and conclusions. Only then can it decide whether the magistrate's findings can be supported. In doing so, it should make an allowance for the fact that the trial court has had the advantage of hearing and seeing the witnesses"."
4. The case before the lower court is that the Appellant, Byron Owino Oyugi was charged before the Senior Principal Magistrate's Court at Madiany with the offence of defilement contrary to Section 8(1) as read with Section 8(3) of the Sexual Offences Act, No. 3 of 2006 . The particulars of the offence were that on diverse dates between 25th April 2025 and 29th April 2025, at Wera Village, Omia Mwalo Sub-Location Rarieda Sub County in Siaya County, intentionally caused his penis to penetrate the vagina of V.A.O , a child aged 13 years
5. The Appellant also faced an alternative charge of committing an indecent act with a child contrary to Section 11(1) of the Sexual Offences Act . The particulars were that on diverse dates between the dates of 25 th April 2025 to 21 st June 2025 in Wera village of Omia Mwalo sub location, Rarieda sub county in Siaya County at unknown time intentionally touched the vagina of V.A.O a child aged 13 years. The Appellant pleaded not guilty to both counts. After a full trial, the learned trial magistrate convicted him on the main count of defilement and sentenced him to serve twenty (20) years imprisonment. The same has precipitated into the present appeal.
6. PW1 V.A.O (The Complainant / Child Survivor) provided primary direct evidence of the defilement occurring between April 25th and April 29th, 2025. She detailed the locus in quo (the Appellant's house within their shared family homestead) and the precise mechanics of the offense stating that the Appellant forcefully pulled her into his room, locked the door, stripped her of her skirt and underpants and inserted his penis into her vagina. She testified that the Appellant is her uncle as he is a brother to her father. That her grandmother used to send her to take food to the Appellant who also lived within the same homestead and that on those occasions he would lock the door and proceed to remove her clothes and then insert his penis into her vagina. She explained her initial silence by indicating that she had a sore throat which was painful due to attending a church kesha (night vigil) the previous night which temporarily incapacitated her voice. She also cited a fear of being beaten by her mother. She testified to a later distinct incident on Saturday June 21st, 2025, where the Appellant chased her, dragged her near a toilet and touched her breasts an act which was interrupted by her mother.
On cross-examination, she stated that it was the Appellant who had defiled her and that her mother found the Appellant fondling her breasts.
7. M.A.O (PW2) was the mother of the complainant who testified that upon going to look for her daughter, she caught the Appellant in flagrant delicto embracing and inappropriately touching the minor’s breasts. She added that the moment the Appellant saw her, he fled the scene. That she chased after the Appellant as she raised alarm and later went back home and upon disciplining the minor for delaying, the child made an immediate, tearful disclosure that the Appellant had previously defiled her in the month of April 2025 and that she had been too terrified to speak about it. She produced the primary identification details confirming the minor’s date of birth as June 10th 2011 making her a child under Kenyan law. She identified the birth certificate as PMFi-1.
8. Ezekiel Kenga (PW3) testified that he is a clinical officer working at Ongido Sub County Hospital. That, he examined the minor on June 22 nd , 2025. That on examination, he noted no fresh external vaginal lacerations or active discharge. That he noticed two critical findings that legally established penetration inter alia; that the minor's hymen was completely broken ; that the minor tested positive for pregnancy (with a distended abdomen and a clinically assessed gestational period of approximately 8 weeks). He noted that the minor's history indicated her last sexual episode was with her uncle in April and that she had missed her menses ever since. He explicitly concluded that the pregnancy and clinical history conclusively confirmed that the complainant had been defiled. He produced the treatment notes and P3 for as exhibits 2 and 3 respectively. On cross-examination, he stated that the pregnancy was positive and which linked the Appellant to it as per the evidence of the minor.
9. No. 116890 PC Samuel Njoroge Mwangi (PW4) was the investigating officer who testified that he received the report on June 22nd, 2025 from the local village elder and the mother of the complainant. That he learnt that the Appellant and the complainant had been engaging in immoral activities. He also learnt that the Appellant had been defiling the minor between 25/4/2025 and 29/4/2025. That he placed the Appellant in custody as he arranged to have the minor taken to hospital for examination. That he secured the minor’s original birth certificate which he produced as PExh 1 which legally anchored her age at 13 years old.
10. The trial court later ruled that a prima facie case had been made out against the Appellant by the Respondent and that the Appellant was subsequently placed on his defence and who elected to tender an unsworn statement and called no witnesses.
11. Byron Owino Oyugi (DW1) was the Appellant who stated that he knew the complainant and further that he was aware of the charges facing him. He stated that he could not recall the events of April 2025 as he was in the lake but he remembers the one wherein the mother of the complainant found him with the minor wherein he stated: "Time passed and her mother found us standing on the path behind my grandmother's house. I saw PW2 and ran away."
12. When confronted with the substantive charge of defilement from April 2025, the Appellant stated: "I cannot remember what happened in April. On that day I was in the lake." He attempted to raise a vague, generic alibi (being a fisherman at the lake) but failed completely to provide specific dates, times or supporting witnesses to back it up.
13. The appeal was canvassed by way of written submissions. The Appellant complied while the Respondent did not.
14. The Appellant submitted that the prosecution bears the absolute burden of establishing its case beyond reasonable doubt by proving three cumulative ingredients of defilement: the age of the victim, the fact of penetration, and the positive identification of the accused. He argued that the prosecution failed to present cogent evidence to clear evidential gaps.
15. To fortify this argument, the Appellant relied on Bakare v. State (1987) 1 NWLR (Pt. 52) 579 : Where Oputa, JSC (Supreme Court of Nigeria) observed that the presumption of innocence requires a high degree of cogency in prosecution evidence to displace it stating that while absolute certainty is impossible, proof beyond reasonable doubt does not admit of plausible possibilities. He also relied on the case of Pius Arap Maina v. Republic (2013) eKLR where the Court of Appeal held that any evidential gaps in the prosecution's case which raise material doubts must invariably be resolved in favor of the accused person.
16. The Appellant further placed his reliance on sections 107(1), 108, and 109 of the Evidence Act (Cap 80, Laws of Kenya) t o assert that anyone who desires a court to give judgment on any liability dependent on facts must strictly prove that those facts exist.
17. While the Appellant did not dispute that the birth certificate indicated the victim's date of birth as 10th June 2011, he raised a material doubt regarding the identity and legitimate ownership of the document. He pointed out distinct discrepancies between the names used. The charge sheet listed the victim as V.A.O. , a minor aged 13 years. The prosecution at various intervals prior to the hearing used two different sets of initials namely V.A.O. and M.A.O. During the hearing, the minor testified using the initials V.A. The Appellant argued that " V.A. " is fundamentally different from " V.A.O. " creating an unresolved fatal defect regarding the victim’s true identity.
18. The Appellant forcefully contested the element of penetration, arguing that PW1 (the complainant) failed to demonstrate or specify how penetration occurred. He submitted that her testimony lacked the mandatory "sensory details" necessary to sustain a conviction based solely on a victim's word. In support of this position, the Appellant relied on the case of Julius Kioko Kivuva v. Republic (2015) eKLR : where the High Court held that evidence of sensory details such as what a victim heard, saw, felt or smelled is highly relevant and necessary to strengthen the credibility of a witness where a conviction rests primarily on the victim's testimony. The Appellant argued that PW1's reference to "tabia mbaya" did not equate to legal penetration.
19. The Appellant pointed out that the medical examination conducted by PW3 (pages 22–23 on the P3 Form) explicitly normalizes the physical anatomy of the victim. It recorded that the labia majora, labia minora, clitoris, peri-urethral area, vestibule and vagina were all normal with no lacerations or discharge thereby negating any medical proof of penetration under Section 2 of the Sexual Offences Act.
20. The Appellant acknowledged that he and the complainant were familiar with each other. However, he maintained that the prosecution failed to prove that he was the person who actually defiled her. Invoking Section 33 of the Sexual Offences Act, the Appellant argued that courts must critically analyze the surrounding circumstances of an alleged crime to deduce if it was likely to have been committed. He characterized the prosecution's case as reliant on weak circumstantial evidence noting that PW1 claimed she was pulled into a house but failed to establish penetration.
21. The Appellant relied on the jurisprudence in P.O.N v. Republic (2019) eKLR where the Court of Appeal ruled that to base a conviction entirely on circumstantial evidence, the inference of guilt must be the only rational inference to be drawn. If any reasonable possibility consistent with innocence exists, the accused must be acquitted. Also in Simon Musoke v. Republic (1958) EA 71 it was held that before drawing an inference of guilt from circumstantial evidence, a court must be absolutely sure that there are no co-existing factors that weaken or destroy that inference. Again in Absalom Amboka Okila v. Republic (2020) eKLR Matheka, J. observed that under Section 33 of the Sexual Offences Act, the circumstances under which an offence is alleged to have been committed cannot be ignored, as they serve as the vital fourth ingredient to determine the likelihood of the offense occurring.
22. Ultimately, the Appellant submitted that the trial court's decision was a product of speculation, contradictions, inconsistencies, and poor investigations. He prayed that the High Court orders inter alia; allow the appeal; quash the conviction; set aside the 20-year prison sentence and to set him at liberty.
23. I have considered the Appeal, the record of appeal and the Appellant’s submissions and find that the issue for determination is whether the prosecution proved its case against the Appellant beyond reasonable doubt.
24. It is trite that in criminal cases, the burden of proof is upon the prosecution to discharge and that the standard of proof is one of beyond any reasonable doubt. See Woolmington Vs Dpp [1935] AC 462.
25. It is noted that the Appellant had been charged with an offence of defilement under section 8(1) as read with section 8(3) of the Sexual Offences Act No. 3 of 2006. In order to prove the offence therein, the Respondent was under obligation to prove certain essential ingredients and that to answer this, the Court must evaluate the three canonical ingredients of defilement namely; the age of the complainant (whether she was a child under the law); the fact of penetration and the positive identification or recognition of the Appellant as the perpetrator. These ingredients must each be proven for a conviction to ensue (See George Opondo Olunga vs Republic [2016] eKLR)
26. S ection 8(1) of the Sexual Offences Act No. 3 of 2006 provides as follows: - (1) A person who commits an act which causes penetration with a child is guilty of an offence termed defilement.
(2) A person who commits an offence of defilement with a child aged eleven years or less shall upon conviction be sentenced to imprisonment for life.
(3) A person who commits an offence of defilement with a child between the age of twelve and fifteen years is liable upon conviction to imprisonment for a term of not less than twenty years.
(4) A person who commits an offence of defilement with a child between the age of sixteen and eighteen years is liable upon conviction to imprisonment for a term of not less than fifteen years.
(5) It is a defence to a charge under this section if
(a) it is proved that such child, deceived the accused person into believing that he or she was over the age of eighteen years at the time of the alleged commission of the offence; and
(b) the accused reasonably believed that the child was over the age of eighteen years.
(6) The belief referred to in subsection (5) (b) is to be determined having regard to all the circumstances, including any steps the accused person took to ascertain the age of the complainant.
(7) Where the person charged with an offence under this Act is below the age of eighteen years, the court may upon conviction, sentence the accused person in accordance with the provisions of the Borstal Institutions Act and the Children's Act.
(8) The provisions of subsection (5) shall not apply if the accused person is related to such child within the prohibited degrees."
27. As regards the age of the victim, it is noted that the same is crucial in that the eventual sentence to be imposed upon conviction is dependent upon the age of the victim.. The Court of Appeal in Edwin Nyambogo Onsongo vs. Republic (2016) eKLR stated as follows in respect of proving the age of a victim in cases of defilement:
“... the question of proof of age has finally been settled by recent decisions of this court to the effect that it can be proved by documents, evidence such as a birth certificate, baptism card or by oral evidence of the child if the child is sufficiently intelligent or the evidence of the parents or guardian or medical evidence, among other credible forms of proof. We think that what ought to be stressed is that whatever the nature of evidence preferred in proof of the victim’s age, it has to be credible and reliable.”
28. Regarding proof of age, and as noted above, it is noteworthy to state at the outset that the importance of proving the age of a victim in sexual offences is paramount considering that under the Sexual Offences Act, the prescribed sentence is determined by the age of the victim.
29. Section 2 of the Children’s Act defines a child as a person under the age of eighteen (18) years. There are various ways which can be used to prove a victim’s age as held in Mwalango Chichoro Mwajembe V Republic, Criminal Appeal No. 24 of 2015 (UR ) where the court stated as follows :
“……..the question of proof of age has finally been settled by a recent decisions of this court to the effect that it can be proved by documentary evidence such as a birth certificate, baptism card or by oral evidence of the child if the child is sufficiently intelligent or the evidence of the parents or guardian or medical evidence, among other credible forms of proof” It has even been held in a long line of decisions from the High Court that age can also be proved by observation and common sense. (See Denis Kinywa -Vs- Republic Criminal Appeal No. 19 of 2014) and (Omar Ucher -Vs- Republic Criminal Appeal No. 11 of 2015). We doubt if the courts are possessed of requisite expertise to assess age by merely observing the victim since in a criminal trial the threshold is beyond any reasonable doubt. This form of proof is a direct influence by the decisions of the Court of Appeal of Uganda in Francis Omuroni -Vs- Uganda Criminal Appeal No. 2 of 2000. We think that what ought to be stressed is that whatever the nature of evidence presented in proof of the victim’s age, it has to be credible and reliable...”
In the present case, the prosecution discharged this burden through the birth certificate (Exhibit 1) produced by PW4, which established that the minor was born on 10/6/2011, making her age as thirteen years at the time of the incident. This was further corroborated by the Clinical Officer (PW3), satisfying the legal threshold. The Appellant in his defence did not dispute the complainant’s age as per the birth certificate and further did not dispute the fact that the complainant was still a minor. I find that the age of the minor (13 years) was proved beyond reasonable doubt
30. As regards the aspect of penetration, section 2 of the Sexual Offences Act No.3 of 2006 defines ‘‘Penetration’’ as the partial or complete insertion of the genital organs of a person into genital organs of another person.
31. Penetration is proved through the evidence of the victim. The testimony of the victim in this case coupled with evidence from other witnesses was sufficient to determine whether penetration occurred. Under the provisions of section 124 of the Evidence Act, the same provides as follows:
"Notwithstanding the provisions of section 19 of the Oaths and Statutory Declaration Act, where the evidence of the victim admitted in accordance with that section on behalf of the Prosecution in the proceedings against any person for an offence, the accused shall not be liable to be convicted in proceedings against him unless it is corroborated by other evidence in support thereof implicating him. Provided that where in a criminal case involving a sexual offence, the only evidence is that of the alleged victim of the offense, the court shall receive the evidence of the alleged victim and proceed to convict the accused person, if for reasons to be recorded in the proceedings, the court is satisfied that the alleged victim is telling the truth."
In the case of Bassita vs. Uganda S.C. Criminal Appeal No. 35 of 1995 it was held thus:
"An intercourse or penetration may be proved by direct or circumstantial evidence. Ally the sexual intercourse is proved by the victim's own evidence and reinforced by the medical evidence or other evidence. Though desirable, it is not hard and fast rule that the victim's evidence and medical evidence must always be adduced in every case of defilement to prove sexual intercourse or penetration. Whatever evidence the prosecution may wish to adduce to prove its case such evidence must be such that is sufficient to prove the case beyond reasonable doubt."
32. The Appellant argues that penetration was not proven because the minor utilized the Swahili phrase "tabia mbaya" (bad behavior) and failed to provide deep sensory details of the act as required under Julius Kioko Kivuva v Republic [2015] eKLR. He further points to the P3 Form where the clinical officer ( PW3) noted that her external genitalia (labia majora, minora, and vestibule) were "normal" and free from fresh lacerations.
33. A holistic reading of the minor’s testimony shatters the Appellant’s line of reasoning. PW1 did not merely stop at "tabia mbaya" . She went on to state categorically “Accused took his penis and inserted in my vagina... Accused removed my skirt and underpants... Accused removed his briefs half way to his knees." This is direct, specific anatomical evidence of penetration as defined under Section 2 of the Sexual Offences Act. Furthermore, the lack of fresh lacerations or bleeding on her external genitalia is medically logical. The defilement occurred between 25th and 29th April 2025 . The medical examination by PW3 was performed on 22nd June 2025 nearly two months later. It is obvious that any superficial external injuries would have long healed. Further, and most damningly, PW3 testified that upon a per-vaginal examination, the minor's hymen was broken and that she tested positive for pregnancy. The clinical officer noted that the abdomen was distended with a growing foetus and that he confirmed the pregnancy was estimated at 8 weeks.
34. Kenyan courts have repeatedly held that a child’s testimony on penetration need not to be scientifically perfect as it conveys the fact of intrusion. In Mark Oiruri Mose v Republic [2013] eKLR , the Court of Appeal stressed that a victim account of how the male genitalia came in contact with her genital is sufficient to prove penetration
35. The minor testified that she had never had sexual intercourse with any other person and thus it was only the Appellant who was her uncle who had defiled her. I have no reason to doubt the testimony of the minor as nothing emerged that her family had any problems with the Appellant. In fact it came out clearly that the complainant was the one who was frequently used by the family to take meals to the Appellant who also lived within the homestead. Consequently, I find the element of penetration was proved beyond a shadow of doubt by the Respondent.
36. The Appellant contends in his submissions that there exists a material doubt regarding the identity of the complainant. He argues that while the charge sheet lists the victim as V.A.O , she gave her name as V.A in court, which creates a fatal discrepancy as to whether she is the legitimate owner of the birth certificate produced. This Court finds this argument to be a hyper-technical distraction devoid of legal merit. The minor ( PW1 ) testified that her name is V.A and that she was 13 years old. Her mother, Maureen Adhiambo Okoth ( PW2) explicitly testified that the minor was her daughter and was born on 10th June 2011. The investigating officer ( PW4) produced the minor's original birth certificate ( PExh 1 ) which verified her birth date as 10th June 2011. The certificate of birth indicated the name of the minor as .V.A. The evidence of the minor and her mother left no doubt that the two names refer to one and the same person and that the person examined by the clinical officer was V.A.O as captured on the P3 form and was the complainant. Again, the Appellant confirmed in his defence evidence that he knew the complainant very well. He was therefore not talking of a stranger but someone he had known quite well. I find the contention by the Appellant to be preposterous and devoid of any merit.
37. As regards the identity of the perpetrator, the complainant stated that the Appellant was well known to her as her uncle and brother to her father. She further confirmed that she used to be sent to the Appellant’s house to take food to him as he also lived within the same homestead. I find that the identification of the Appellant was firm, consistent and free from any possibility of mistake. The complainant knew the Appellant prior to the incident and positively recognized him as the perpetrator. This was therefore a case of recognition rather than identification of a stranger, which Kenyans courts have consistently held that to be the most reliable form of identification. In Anjononi & Others v Republic [1980] eKLR , the Court of Appeal held that recognition is ‘‘more reliable than identification of a stranger because it is based on the witness’s prior knowledge of the accused’’. The Complainant’s evidence was direct, unwavering and supported by circumstances of close physical proximity during the commission of the offence which left no room for doubt. Further, it is noted that the Appellant concedes in his submissions that he and the complainant are well known to each other. They reside within the same homestead. It emerged that the Appellant is the paternal uncle of the minor ( "a brother to my father" as PW1 testified). The offence took place at 1:00 p.m. in broad daylight inside the Appellant's house. This is an absolute case of recognition which minimizes the possibility of mistaken identity. It is further noted that the complainant’s mother found the Appellant in a compromising situation with her daughter, as he was then fondling her breasts and had enveloped her in a tight embrace (flagrant delicto) and that on seeing her, he took off and that she gave chase after him as she raised alarm. Furthermore, the narrative contains strong circumstantial and corroborative elements. On 21st June 2025, the minor’s mother ( PW2 ) caught the Appellant holding and embracing the minor on a path near a maize plantation at 7:00 p.m. Upon being spotted, the Appellant immediately took off and fled. In his own statutory defense the Appellant (DW1) admitted to this exact encounter:
"Time passed and her mother found us standing on the path behind my grandmother's house. I saw PW2 and ran away."
Under Section 8 of the Evidence Act (Cap 80), the conduct of an accused person during or after the alleged offence is highly relevant. The Appellant's flight upon being spotted with the minor is highly inconsistent with the behavior of an innocent uncle and strongly corroborates the minor's subsequent immediate disclosure to her mother that she had been defiled by him earlier between 25/4/2025 and 29/4/2025. Iam satisfied that the ingredient of identification was therefore sufficiently proved
27. 38. An analysis of the lower court record leaves no doubt that the learned trial magistrate carefully analyzed the evidence of the minor, the mother, the medical professional and the investigating officer. The defence raised by the Appellant was a mere bare denial coupled with a selective admission of the events of 21st June 2025. The Appellant offered no reasonable explanation as to why an innocent paternal uncle would flee into a maize plantation at night upon merely being seen with his niece by her mother. I find that the Respondent established all ingredients of the offence against the Appellant herein beyond any reasonable doubt. Hence, the finding on conviction by the trial court was quite sound and must be upheld.
39. On whether the sentence imposed upon the Appellant was appropriate, the statutory prescription and judicial discretion , the trial court imposed a sentence of twenty years’ imprisonment pursuant to Section 8(3) of the Sexual Offences Act, which prescribes this penalty for the defilement of a child aged between 12 to 15 years. While the Supreme Court in Francis Karioko Muruatetu & Another v Republic [2017] eKLR declared mandatory minimum sentences unconstitutional, it affirmed that courts must consider the gravity of the offense and the specific circumstances before sentencing. In Jared Koita Injiri v Republic [2019] eKLR , the Court of Appeal upheld a life sentence for defilement of a minor, noting that despite the discretion granted by Muruatetu , the severity of the crime against a child of tender years justifies the harshest penalty. The trial magistrate exercised this discretion, noting the mandatory nature of the provision and the need to deter such conduct.
40. In the case of Shadrack Kipkoech Kogo - vs - R. Eldoret Criminal Appeal No.253 of 2003 the Court of Appeal stated thus as regards interference with sentence: -
“sentence is essentially an exercise of discretion by the trial court and for this court to interfere it must be shown that in passing the sentence, the sentencing court took into account an irrelevant factor or that a wrong princ
