On May 20, 2026, the Milimani High Court in Nairobi issued a landmark ruling Verdict In Petition E490/2025 This fundamentally changes the way Kenyan law is addressed consensual sex between minors. In a judgment delivered by Justice Bahati Mwamuye, the court held that the application of Sections 8, 9 and 11 of the Sexual Offenses Act (SOA) toward teenagers in consensual, age-appropriate relationships “violates multiple constitutional rights.” The petition was submitted by three anonymous young people (referred to as HSO, AMO and TA) and the youth organization Network for Youth and Young People of Africa (NAYA) against the Attorney General and three state agencies. It challenged the wholesale criminalization of sex with teenagers as being incompatible with Articles 27, 28, 31, 43 and 53 of the 2010 Law Constitutionensure the equality, dignity, privacy, health, education and welfare of the child.
The plaintiffs, represented by Center for Reproductive Rights and Reproductive Health Network Kenyarecounted how police arrested her and charged her under defilement laws, even though there was no evidence of violence or exploitation. For example, in one case, a 17-year-old boy was charged after police searched the bedroom he shared with his 16-year-old girlfriend; In another case, a 17-year-old was prosecuted because his partner’s pregnancy led to a defilement charge – which was withdrawn once his minor status was confirmed. The petitioners argued that such enforcement “broadly and harmfully criminalizes the youth-peer relationships that the law was intended to protect.” They insisted that the law must draw a line between exploitative abuse and consensual intimacy between teenagers to avoid derailing youth into the criminal justice system.
Respondents – through the Attorney General’s Office and security agencies – countered that the SOA sections are necessary to protect minors and that strict enforcement prevents loopholes for criminals. They emphasized protecting the safety of children, particularly in the context of widespread gender-based violence. The judge acknowledged these concerns, but noted that “anything short of a contextual approach would allow criminal law to function in a manner divorced from constitutional values.” In other words, blanket prosecution of consensual teenage couples endangers the rule of law by overriding constitutional rights.
In its reasoning, the court made a sharp distinction between two categories: “consensual, non-coercive and non-exploitative sexual behavior between young people in a close age relationship” on the one hand and “non-consensual, coercive, exploitative or abusive” behavior on the other. Judge Mwamuye ruled that investigative and law enforcement agencies must treat these scenarios differently. Police, prosecutors and courts are now required to consider the context of each case – including the ages of the parties, evidence of consent and any power imbalances – before bringing libel charges. The court emphasized that the SOA “must be construed in accordance with the Constitution” and must be interpreted in accordance with fundamental rights.
The orders resulting from the judgment were comprehensive. The Director of Public Prosecutions has been ordered to formalize and publish clear guidelines for dealing with cases of consensual sex involving teenagers, and the national police service must review its arrest and interrogation protocols regarding minors. State authorities responsible for health, education and child protection have been ordered to develop guidelines so that young people can access sexual and reproductive health information “without fear of criminalization”. Crucially, the court permanently stayed two defilement cases pending before the Makadara Court – CR No. 34 of 2025 and MSCO/E239 of 2023 – provided they were fully consensual relationships under the age of 18. Each party was ordered to bear its own costs as this was a public interest litigation.
The response from Kenyan legal and civil society actors was swift. Former President of the Law Society, Faith Odhiambo praised The decision called the decision a “major turning point” in the justice system’s treatment of adolescent sexuality. She pointed out that the verdict confirmed that treating normal teenage relationships as crimes violated young people’s rights to equality, dignity, privacy, health, education and their well-being. Victor Rasugu from NAYA commented that young people have long “lived in fear…fear that a relationship could land them in a police cell,” and praised the ruling’s potential to ease that fear. At the same time, observers warned that it could be difficult to draw the line in future cases. Odhiambo warned that implementation could be difficult, especially given the severe gender-based violence crisis in Kenya.
The impact on the rule of law is profound. By insisting that criminal law enforcement be consistent with constitutional standards, the Supreme Court affirmed that even well-intentioned laws cannot override fundamental rights. The ruling’s context-based approach prevents the mechanical application of defilement laws to consensual teen behavior. In practice, it prohibits automatic arrests for sex between peers under 18, requiring authorities to instead focus on coercion or abuse when children’s well-being is truly at stake. Many commentators believe that this clarity will reduce arbitrary prosecutions of juveniles and promote proportionality and fairness, which are core principles of the rule of law. If carefully implemented, the ruling will ensure that Kenyan laws protect children without criminalizing normal adolescent behavior.
