Muruatetu & another v Republic; Katiba Institute & 5 others (Amicus Curiae)
The bottom line
#Mandatory death sentence for murder in Kenya is unconstitutional; courts must now consider mitigating factors.
What this practically means
#The Supreme Court ruled that the automatic death sentence for murder violates the Constitution. Every convicted person now has the right to present reasons why they should not be executed. Courts must listen to these reasons and decide an appropriate sentence, which could be death or a lesser penalty. This ruling applies to all murder cases, including those already sentenced.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the mandatory nature of the death penalty provided for in the Penal Code under section 204 is unconstitutional?
- 2.Whether the indeterminate life sentence should be declared unconstitutional?
- 3.Whether this court can or should define the parameters of a life sentence; and
- 4.What remedies, if any, accrue to the petitioners?
Key legal issues
#Whether the mandatory nature of the death penalty under section 204 of the Penal Code is unconstitutional.
The mandatory death sentence is unconstitutional because it violates the right to a fair trial (Article 50), the right to dignity (Article 28), the right to equality (Article 27), and access to justice (Article 48). It deprives the court of judicial discretion and denies the convict an opportunity to be heard in mitigation.
The court reasoned that sentencing is a crucial component of a trial and the right to a fair trial extends to the sentencing stage. Section 204, by mandating the death sentence, prevents the court from considering mitigating circumstances, thereby treating all murder convicts as an undifferentiated mass and violating their dignity. It also denies convicts the right to have their sentence reviewed by a higher court, as the appeal is limited to conviction. The court found that this mandatory aspect is inconsistent with the progressive Bill of Rights in the Constitution.
Whether the indeterminate life sentence should be declared unconstitutional.
The court declined to make a determination on this issue because the petitioners did not sufficiently argue and illustrate the particulars of why the indeterminate life sentence should be declared unconstitutional.
The court noted that the petitioners' submissions were inadequate and that a critical issue such as this, where legislation is to be examined, is deserving of reasoned arguments from all parties and input from the High Court and Court of Appeal. The court did not want to act as a court of first and last instance on this matter.
Whether this court can or should define the parameters of a life sentence.
The court held that it is not for the Judiciary to define what constitutes a life sentence; this is a function within the realm of the Legislature.
The court relied on Article 51 of the Constitution, which tasks Parliament with enacting legislation for the humane treatment of detained persons. It also agreed with the High Court decision in Jackson Maina Wangui that determining what amounts to life imprisonment is a matter for the legislative branch. The court recommended that the Attorney General and Parliament develop legislation on the definition of a life sentence.
What remedies accrue to the petitioners?
The appropriate remedy is to remit the matter to the High Court for a sentencing re-hearing, where the court will consider mitigating factors and pass an appropriate sentence.
The court was persuaded by comparative jurisprudence from Belize (Reyes), Uganda (Kigula), and Malawi (Kafantayeni), where the practice upon declaring the mandatory death penalty unconstitutional was to remit the case for resentencing. The court held that the petitioners are deserving of a remedy as they were denied a fair trial, and the High Court is best placed to hear mitigation and determine an appropriate sentence.

The bench

- Jurisdiction invoked
- Article 163(4)(a) of the Constitution

Relief refused
#Declaration that the indeterminate life sentence is unconstitutional
The court found that the petitioners had not sufficiently argued and illustrated the particulars of why the indeterminate life sentence should be declared unconstitutional, and that a critical issue such as this is deserving of reasoned arguments and input from lower courts.
Order fixing a definite number of years to constitute life imprisonment
The court held that defining what constitutes a life sentence is a function within the realm of the Legislature, not the Judiciary.
Award of damages for unconstitutional detention
The court did not grant this prayer; instead it remitted the matter to the High Court for sentencing, implicitly rejecting the claim for damages at this stage.
Application of the declaration to all convicts suffering the same fate
The court limited the sentencing re-hearing to the two petitioners and directed that other existing or intending petitioners should await appropriate guidelines.
Costs
No order as to costs was made in the judgment.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
Consequently, we find that section 204 of the Penal Code is inconsistent with the Constitution and invalid to the extent that it provides for the mandatory death sentence for murder. For the avoidance of doubt, this decision does not outlaw the death penalty, which is still applicable as a discretionary maximum punishment.
We do this by determining that any court dealing with the offence of murder is allowed to exercise judicial discretion by considering any mitigating factors, in sentencing an accused person charged with and found guilty of that offence.
The mandatory nature of the death sentence as provided for under section 204 of the Penal Code is hereby declared unconstitutional. For the avoidance of doubt, this order does not disturb the validity of the death sentence as contemplated under article 26(3) of the Constitution.
This matter is hereby remitted to the High Court for re- hearing on sentence only, on a priority basis, and in conformity with this judgment.
Key timeline
#Practical implications
#Prepare for resentencing hearings
Lawyers representing murder convicts sentenced to death must now file applications for resentencing. Gather mitigating evidence such as character, circumstances, and remorse to argue for a lesser sentence. The High Court will conduct a hearing on sentence only, so focus on building a strong mitigation case.
Review internal disciplinary procedures
The principle of fair hearing in sentencing may influence how businesses handle employee discipline. Ensure that employees are given a chance to present mitigating factors before termination or other severe penalties. This aligns with constitutional values of dignity and fair process.
Know your rights if charged with murder
If you are charged with murder, you now have the right to present evidence of mitigation at sentencing. This could reduce your sentence from death to life imprisonment or a term of years. Ensure your lawyer prepares a strong mitigation case, including personal background and circumstances.
