Court Strikes Blow to Blanket Prosecution of Consensual Teen Sex

The High Court has delivered a constitutional ruling declaring that the indiscriminate criminal prosecution of consensual sexual relationships between adolescents violates constitutional protections.

In a judgment issued in Constitutional Petition No. E490 of 2025, Justice Bahati Mwamuye found that applying Sections 8, 9, 11, and 43 of the Sexual Offences Act against minors involved in consensual, non-exploitative, and non-coercive sexual activity was inconsistent with constitutional principles safeguarding dignity, equality, and the best interests of children.

“The Constitution demands protection, guidance, and rehabilitation of children, not punitive criminal sanctions in situations where adolescents engage in consensual relationships absent coercion, manipulation, or exploitation,” Justice Mwamuye ruled.

Court Issues Order to Amend Guidelines on Prosecutions

Further, the court ordered the Director of Public Prosecutions’ office to amend its prosecutorial guidelines so that teenagers who enter into consensual relationships do not automatically face defilement charges according to existing law.

Justice Mwamuye observed that the current wording and implementation of the Sexual Offences Act fail to distinguish between predatory sexual conduct and consensual adolescent relationships involving minors close in age.

The petitioners argued that the blanket criminalisation of all sexual activity involving persons below the age of 18 had adverse social and health consequences for adolescents.

They told the court that fear of arrest and prosecution discourages teenagers from accessing reproductive health services and counselling support, ultimately undermining efforts to protect vulnerable young people.

Legal scholars and child rights advocates have for years questioned the proportionality of the law.

Among them was lawyer Caroline Oduor, who previously argued that criminal penalties imposed on adolescents in consensual relationships failed to satisfy constitutional standards on human dignity and the welfare of children.

Concerns Over Mandatory Sentencing

The ruling comes amid increasing pressure on Parliament to reconsider aspects of the Sexual Offences Act No. 3 of 2006, particularly mandatory sentencing provisions in defilement cases.

Debate intensified earlier this year during oversight visits by the Constitutional Implementation Oversight Committee to correctional facilities in Kisumu County.

During those visits, prison authorities and legal experts expressed concern that mandatory prison terms ranging from 15 to 20 years leave little room for courts to evaluate mitigating factors, including the age difference between accused persons and complainants, mutual consent, and absence of exploitative intent.

Statistics presented before lawmakers indicated that sexual offences account for more than 31% of the country’s prison population, with defilement-related convictions forming the largest proportion of those cases.
