On May 20, a landmark ruling from Nairobi’s Milimani High Court struck down the application of Kenya’s defilement laws to consensual sex between teenagers. Justice Bahati Mwamuye held that Sections 8, 9, and 11 of the Sexual Offences Act violate constitutional rights when used against adolescents in close-in-age, non-coercive relationships.
The decision in Petition E490/2025 came in response to a challenge.
The challenge was filed by three anonymized minors—identified as HSO, AMO, and TA—and the youth organization Network for Adolescent and Youth of Africa (NAYA). They argued the broad criminalization of teen sex conflicted with Articles 27, 28, 31, 43, and 53 of Kenya’s 2010 Constitution, which protect equality, dignity, privacy, health, education, and the best interests of the child.

How police arrests brought the case to court
The petitioners, represented by the Centre for Reproductive Rights and Reproductive Health Network Kenya, described real cases. In one instance, police raided the bedroom a 17-year-old boy shared with his 16-year-old girlfriend and charged him with defilement. In another, a 17-year-old faced prosecution after his partner became pregnant—the charges were later dropped once his own minor status was confirmed. They argued that such enforcement “broadly and harmfully criminalize[d] adolescent peer relationships” and forced teenagers into the criminal justice system where the law was meant to protect them.
Government argued it needed to protect minors
The respondents—through the Office of the Attorney General and security agencies—defended the law as necessary to safeguard children, especially given widespread gender-based violence. Justice Mwamuye acknowledged that concern, but ruled that “anything less” than a contextual approach would let criminal law operate “in a manner disconnected from constitutional values.” He found that blanket prosecutions of mutual teen couples overrode fundamental rights guaranteed in the Constitution.
The court drew a clear line between consent and abuse
The judge distinguished two categories: “consensual, non-coercive and non-exploitative sexual conduct between adolescents of close age proximity” versus “non-consensual, coercive, exploitative or abusive” conduct. Police, prosecutors, and courts must now examine context—ages, evidence of consent, power imbalances—before bringing such charges. The ruling orders that the Sexual Offences Act “must be interpreted in harmony with the Constitution.”

Orders include new guidelines for police and prosecutors
It directed the Public Prosecution’s Office to formalize and publish clear guidelines for handling mutual teen sex cases. The National Police Service must review its arrest and interrogation protocols for minors. State health, education, and child protection agencies were told to develop policies so adolescents can access sexual and reproductive health information “without fear of criminalization.” The court also permanently stayed two pending defilement cases in Makadara Court—CR No. 34 of 2025 and MSCO/E239 of 2023—insofar as they involved fully consensual under-18 relationships.
Each party was ordered to bear its own costs.
This recognized the public-interest nature of the case.

Reactions: relief and caution from civil society
Former Law Society president Faith Odhiambo called the decision a “major turning point” for how Kenya’s justice system treats adolescent sexuality. She said the ruling affirmed that criminalizing normal teen relationships had violated rights to equality, dignity, privacy, health, education, and the best interests of children. Victor Rasugu of NAYA said young people had “lived in fear… afraid that a relationship could land them in a police cell” and praised the judgment’s potential to relieve that fear. But Odhiambo also warned that implementation could be difficult, especially amid Kenya’s serious gender-based violence crisis—drawing the right line in future cases won’t be easy.
What the ruling means for the rule of law
By requiring enforcement of criminal law to align with constitutional norms, the High Court reinforced that well-intentioned statutes cannot override fundamental rights. The context-based approach prevents automatic arrests for under-18 sex between peers and directs authorities to focus on coercion or abuse. Many commentators believe this clarity will reduce arbitrary prosecutions of adolescents and promote proportionality and fairness—core principles of the rule of law. If faithfully implemented, the ruling ensures Kenya’s laws protect children without criminalizing normal adolescent behavior.
