Reforming the Sexual Offences Act in Kenya:
Restoring Judicial Discretion
In 2022, Justice Defenders supported a group of paralegals at Kamiti Maximum Prison who filed a constitutional petition challenging the mandatory minimum sentences in Kenya’s Sexual Offences Act. These laws required courts to impose fixed sentences without considering the circumstances of each case, leaving judges unable to weigh factors such as age, intent or the unique background of the accused. For many people in prison, particularly minors charged alongside other minors, this resulted in long sentences that did not reflect the realities of their cases.
The petition was prepared and filed in December 2021 by three Kamiti paralegals and three of their clients, with support from Justice Defenders graduates and staff. They argued that mandatory minimums removed a court’s duty to consider mitigation and violated fundamental rights, including the right to a fair trial and the right to equal treatment under the law. Justice George Odunga of the Constitutional Court in Machakos agreed and ruled that prescriptive sentences within the Act were unconstitutional. The Court held that sentencing must involve careful judicial consideration and that people previously sentenced without such consideration should be eligible for resentencing.
The impact was immediate. Hundreds of people convicted under mandatory minimums could now return to court to have their sentences reviewed. The ruling also prevented future cases from being decided under rigid guidelines that had tied the hands of judges. For people like seventeen year old Samuel Muthee, who was convicted after a consensual relationship between two minors, the change meant freedom. His case was taken up by paralegal Peter Kago, who challenged the assumptions built into the law and argued for an approach that recognised the complexities of cases involving minors. Samuel was released after the judgment.
The petition came from people living the realities of the law. Paralegals such as Peter Mueke Maingi, Peter Thanga Kago and Nathan Khaemba submitted the case because they saw daily how mandatory sentencing affected those around them. Their insight came from the lives they lived behind bars, where they witnessed the consequences of rigid laws that overlooked context and placed minors and first-time offenders on the same scale as violent perpetrators. Their work turned personal experience into legal reform that reached far beyond the prison gates.
The Court’s decision has now been appealed and will be reviewed by the judiciary, but it remains one of the most significant sentencing reforms in recent years. It affirms that courts must be able to evaluate each case on its own facts and that people caught up in the criminal justice system should not be defined solely by the label of the offence.
The petition also reflects a core Justice Defenders principle. When people with lived experience of the justice system are equipped with legal training, they can challenge laws that do not serve the public well and advocate for reforms that strengthen fairness and accountability. The Sexual Offences Act petition shows how legal empowerment inside prisons can lead to national change and demonstrates that those most affected by the law have an essential role in shaping it.
