School-going teenagers will no longer face automatic defilement charges over consensual relationships

School-going teenagers arrested and dragged through criminal courts, detained, and handed defilement charges for consensual peer relationships will no longer face automatic prosecution after the High Court delivered a landmark ruling declaring that child protection laws have for years been weaponised against the very learners they were meant to protect.

Justice Bahati Mwamuye delivered the ruling on May 20, 2026, in Constitutional Petition No. E490 of 2025, declaring that applying Sections 8, 9, and 11 of the Sexual Offences Act (SOA) to consensual, non-coercive, and non-exploitative sexual conduct between adolescents of close age proximity violates the Constitution.

The petition was filed in August 2025 by the Centre for Reproductive Rights and the Reproductive Health Network Kenya (RHNK) on behalf of three affected adolescents and the Network for Adolescents and Youth of Africa (NAYA), a youth-led organisation. It challenged prosecutions arising from two criminal cases at the Makadara Chief Magistrate’s Court involving teenagers aged between 17 and 19 years.

What the law stated before the ruling

Enacted in 2006, Kenya’s Sexual Offences Act imposed a blanket ban on sexual activity involving anyone below 18 years, treating all minors as legally incapable of giving consent to sexual activity regardless of the circumstances or age proximity involved.

Section 8 of the Act, which deals with defilement, prescribed mandatory prison sentences ranging from 15 years to life imprisonment depending on the age of the victim. A conviction involving a child aged 11 years or below attracted life imprisonment. Where the victim was between 12 and 15 years, the mandatory minimum sentence was 20 years, while cases involving victims aged between 16 and 18 years attracted a minimum sentence of 15 years.

Section 9 criminalised attempted defilement and carried a mandatory minimum sentence of 10 years imprisonment. Section 11, which deals with indecent acts involving minors, similarly imposed imprisonment terms of not less than 10 years upon conviction.

The law made no distinction between predatory sexual abuse and consensual relationships involving adolescents of close age proximity. Courts consistently held that once the complainant was proved to be below 18 years, consent became legally irrelevant.

The law was also applied unevenly along gender lines. In many cases involving teenagers of similar ages, one party was prosecuted while the other was treated as the complainant, with criminal liability largely falling on male adolescents due to the legal construction of the offence around penetration.

Sexual offences accounted for more than 31 percent of Kenya’s prison population before the ruling, with defilement-related convictions forming the largest share.

Impact on learners

The petition detailed the consequences faced by school-going teenagers charged over consensual peer relationships.

One petitioner identified as HSO, aged 17, was arrested alongside his 16-year-old partner after police raided their home in February 2025. He was charged with defilement and detained after failing to raise bail, before later securing release following intervention by NAYA.

In another case, a teenager identified as AMO was arrested and charged with defilement at the age of 17 after a consensual relationship resulted in pregnancy in 2022. Although the charges were eventually withdrawn in May 2025, the prolonged prosecution reportedly affected his education, mental wellbeing, and future opportunities.

The petitioners argued that adolescents prosecuted over consensual relationships suffered interrupted schooling, detention, stigma, psychological harm, and long-term social consequences. They further stated that fear of prosecution discouraged school-going teenagers from seeking reproductive health information and adolescent-friendly healthcare services.

Data from the Kenya National Bureau of Statistics (KNBS) cited in the petition indicated that teenage pregnancy cases increased from 224,333 in 2025 to 235,938 in 2026.

Court orders

Justice Mwamuye declared that applying Sections 8, 9, and 11 of the Sexual Offences Act to adolescents involved in consensual peer relationships, without evidence of exploitation, coercion, abuse, or power imbalance, is inconsistent with Articles 27, 28, 31, 43, and 53 of the Constitution. The court also permanently stayed the two criminal cases before it.

However, the ruling does not lower Kenya’s age of consent or decriminalise statutory sexual offences. Instead, it requires the law to distinguish between exploitative abuse and consensual adolescent peer relationships.

The Office of the Director of Public Prosecutions (ODPP) was directed to formalise and publish prosecutorial guidelines distinguishing consensual adolescent peer conduct from exploitative sexual offences. The National Police Service (NPS) was also ordered to review arrest and investigation procedures involving minors accused of sexual offences.

The court further directed state agencies responsible for health, education, and child protection to develop coordinated policies ensuring adolescents can access sexual and reproductive health information and services without fear of criminalisation.

Former Law Society of Kenya (LSK) President Faith Odhiambo called for legislative reforms that protect children from exploitation without criminalising age-appropriate peer relationships. She noted that the long-term impact of the judgment would depend on how it is implemented and interpreted in future prosecutions.

The ruling is expected to influence how schools, prosecutors, and child protection agencies handle adolescent sexuality cases and may reignite debate on comprehensive reproductive health education within schools.
