The sentencing of Christopher Okello Onyum to death has reignited public debate about how capital punishment is actually implemented in Uganda—and whether a death sentence automatically leads to execution. In practice, it does not. In this report, we look at three things Museveni can do to Christopher Okello Onyum.
Uganda’s legal framework provides a multi-layered process that combines judicial review and executive discretion, meaning that a person sentenced to death still has several legal avenues before any execution can take place.
The Legal Process After a Death Sentence
Following a death sentence by the High Court, a convict is entitled to appeal. The case may proceed to the Court of Appeal and, ultimately, the Supreme Court if necessary. These appellate stages are critical, as they allow higher courts to review both the conviction and the sentence.
Only after the exhaustion of all appeals does the matter move beyond the judiciary.
The President’s Constitutional Role
At the final stage, the process shifts to the executive arm of government. Under Article 121 of the Constitution, the President is empowered to exercise what is known as the Prerogative of Mercy.
This authority allows the President, acting on advice from the Advisory Committee on the Prerogative of Mercy, to grant a full pardon, commute a death sentence to life imprisonment, or respite or delay the execution.
This means that even after the courts have upheld a death sentence, execution is not automatic. It requires a further executive decision.
“121. Prerogative of mercy
(1) There shall be an Advisory Committee on the Prerogative of Mercy which shall consist of—
(a) the Attorney General who shall be the Chairperson; and
(b) six prominent citizens of Uganda appointed by the President.
(2) A person shall not be qualified for appointment as a member of the committee if he or she is a member of Parliament, the Uganda Law Society or a district council.
(3) A member appointed under clause (1)(b) of this Article shall serve for a period of four years and shall cease to be a member of the committee—
(a) if circumstances arise that would disqualify him or her from appointment; or
(b) if removed by the President for inability to perform the functions of his or her office arising from infirmity of body or mind or for misbehaviour, misconduct or incompetence.
(4) The President may, on the advice of the committee—
(a) grant to any person convicted of an offence a pardon either free or subject to lawful conditions;
(b) grant to a person a respite, either indefinite or for a specified period, from the execution of punishment imposed on him or her for an offence;
(c) substitute a less severe form of punishment for a punishment imposed on a person for an offence; or
(d) remit the whole or part of a punishment imposed on a person or of a penalty or forfeiture otherwise due to Government on account of any offence.
(5) Where a person is sentenced to death for an offence, a written report of the case from the trial judge or judges or person presiding over the court or tribunal, together with such other information derived from the record of the case or elsewhere as may be necessary, shall be submitted to the Advisory Committee on the Prerogative of Mercy.
(6) A reference in this Article to conviction or imposition of a punishment, sentence or forfeiture includes conviction or imposition of a punishment, penalty, sentence or forfeiture by a court martial or other military tribunal except a field court martial.” Article 121 of Uganda’s Constitution
A Precedent: The Case of Chris Rwakasisi
Uganda has previously witnessed high-profile cases that illustrate how this process works in practice.
Chris Rwakasisi, a former security chief, was sentenced to death in 1988 and spent more than 20 years on death row. In 2009, President Yoweri Museveni exercised his constitutional powers and granted him a pardon, leading to his release from Luzira Maximum Security Prison.
The case demonstrated that a death sentence can ultimately be overturned through executive action.
The Reality of Death Row in Uganda
Uganda has not carried out executions in recent decades, despite courts continuing to issue death sentences in capital cases such as murder. As a result, many inmates remain on death row for extended periods.
This has created a situation where the death penalty exists in law but is rarely implemented in practice.
What Lies Ahead for Okello
For Christopher Okello Onyum, the immediate next step is the appeals process. His legal team may challenge both the conviction and the sentence in higher courts. Should the appeals fail, his fate would then fall within the scope of presidential discretion under the Prerogative of Mercy.
Until all these stages are completed, his sentence remains legally significant but not final in practical terms.
A System of Law and Discretion
Okello’s case underscores a broader reality about capital punishment in Uganda: the ultimate outcome is shaped by both the judiciary and the executive.
While courts determine guilt and impose sentences, the final step—whether a death sentence is carried out, reduced, or set aside—rests within a constitutional framework that allows for review, delay, and, in some cases, mercy.
In that sense, a death sentence marks not the end of the process, but the beginning of a new and uncertain phase in the pursuit of justice.
Meanwhile, Uganda Prisons boss Byabashaija has made it clear that Christopher Okello Onyum will be hanged with in 72 hours after Museveni signs death warrant. (See Details HERE).
