The bottom line

#

The Court of Appeal refused to reduce a defilement sentence after delivering its judgment, confirming it cannot reopen its own decisions and Muruatetu resentencing only applies to murder cases.

What this practically means

#

Executive summary

#
This is a ruling of the Court of Appeal at Mombasa (Murgor, Laibuta and Ngenye-Macharia JJ.A.) on an undated application by Herman Mwero Mwavughanga seeking resentencing after the Court, on 8 December 2023, substituted his life sentence for defilement with 35 years' imprisonment. The applicant invoked clause 4.8.18 of the Judiciary Sentencing Guidelines, 2023, Article 28 and Article 27 of the Constitution, and the Court of Appeal decision in Ali Abdallah Mwanza v Republic, contending that finalized cases may be reopened for resentencing and that he was entitled to equal treatment given his age. The respondent opposed, submitting that the Court had become functus officio after delivering its judgment and that any challenge to the sentence lay in the Supreme Court. The Court framed the threshold question as whether it retained jurisdiction to resentence, or was functus officio. Applying the Supreme Court's articulation of the doctrine in Raila Odinga v IEBC, it held that having perfected its judgment it had performed all its duties and could not sit in appeal over its own decision; the only remedy is an appeal to the Supreme Court under Article 162 of the Constitution. It further held that clause 4.8.18, read in context with clause 4.8.1, governs resentencing flowing from Muruatetu I and II and applies only to offenders convicted of murder subjected to the mandatory death penalty; the applicant, convicted of defilement under section 8(1) as read with section 8(2) of the Sexual Offences Act, was ineligible. Relying on Lillian S and Samuel Kamau Macharia, the Court concluded it lacked jurisdiction and dismissed the application. No order as to costs was made.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.Whether the Court of Appeal has jurisdiction to entertain an application for resentencing after it has delivered judgment in the applicant's appeal, or whether it is functus officio
  2. 2.Whether clause 4.8.18 of the Judiciary Sentencing Guidelines, 2023 confers jurisdiction on the Court to reopen a finalized case for resentencing
  3. 3.Whether the applicant, convicted of defilement rather than murder, is eligible for resentencing under the Muruatetu jurisprudence and the Sentencing Guidelines

Key legal issues

#
01

Functus officio and the finality of a delivered judgment

Holding

Having heard and determined the applicant's appeal on 8 December 2023, the Court has performed all its duties and is functus officio; it cannot sit on appeal over its own decision, and any challenge must proceed to the Supreme Court.

Reasoning

The Court adopted the doctrine of finality as stated by the Supreme Court in Raila Odinga & 2 Others v IEBC: a court is functus once its judgment or order has been perfected, the doctrine permitting only correction of clerical errors. An invitation to resentence after delivery of judgment would amount to the Court reviewing its own decision, which the law forbids; the proper remedy is an appeal to the Supreme Court under Article 162 of the Constitution.

02

Scope of clause 4.8.18 of the Judiciary Sentencing Guidelines, 2023

Holding

Clause 4.8.18 does not confer a general power to reopen finalized cases; read in context, it concerns resentencing hearings following Muruatetu I and II, which apply to offenders convicted of murder subjected to the mandatory death penalty.

Reasoning

The applicant had cited clause 4.8.18 out of context. Clause 4.8.1 makes clear that the Guidelines' resentencing provisions respond to Muruatetu, entitling offenders convicted of murder and subject to the mandatory death penalty to a resentencing hearing on mitigation. The applicant was convicted of defilement under section 8(1) as read with section 8(2) of the Sexual Offences Act, not murder, and therefore falls outside the Guidelines' resentencing framework.

p. 3
03

Jurisdiction as a threshold prerequisite

Holding

Jurisdiction flows from the Constitution or statute and cannot be assumed; lacking jurisdiction to entertain the resentencing motion, the Court must down its tools.

Reasoning

Relying on Owners of the Motor Vessel 'Lillian S' v Caltex Oil (Kenya) Ltd and Samuel Kamau Macharia v Kenya Commercial Bank, the Court reiterated that a court can only exercise jurisdiction as conferred by the Constitution or written law, and a decision rendered without jurisdiction amounts to nothing. Since no provision of law confers jurisdiction on the Court of Appeal to resentence a party whose appeal it has finally determined, the application could not be entertained.

p. 4

Legal principles established

#
  • Once the Court of Appeal has rendered its decision on conviction and sentence, it is functus officio and cannot reopen or review its own judgment; the only avenue is an appeal to the Supreme Court under Article 162 of the Constitution.
  • The resentencing jurisdiction under clause 4.8.18 of the Judiciary Sentencing Guidelines, 2023 applies only to offenders convicted of murder and sentenced to the mandatory death penalty pursuant to Muruatetu I and II, and does not extend to persons convicted of defilement.

Application for resentencing by the Court of Appeal following its judgment of 8 December 2023 substituting a 35-year sentence for life imprisonment

The Court, having rendered its decision, is functus officio and lacks jurisdiction to review its own judgment; the applicant was convicted of defilement, not murder, and is thus ineligible for resentencing under the Muruatetu-based Guidelines; any challenge lies to the Supreme Court

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.

A court is functus when it has performed all its duties in a particular case.
p. 2Definition of functus officio (quoting the Supreme Court in Raila Odinga v IEBC)
An appeal against a decision of this Court can only be heard and determined by the Supreme Court by dint of Article 162 of the Constitution. But, this Court having rendered a decision on conviction and sentence of the applicant, it is functus oficio.
p. 2Finality of Court of Appeal decisions; the only remedy is appeal to the Supreme Court
He is therefore not eligible for resentencing as sought in the application.
p. 3Muruatetu resentencing confined to murder convictions, not defilement
A Court's jurisdiction flows from either the Constitution or legislation or both. Thus, a Court of law can only exercise jurisdiction as conferred by the Constitution or other written law. It cannot arrogate to itself jurisdiction exceeding that which is conferred upon it by law.
Jurisdictional limits of courts (quoting the Supreme Court in Samuel Kamau Macharia)
In sum, the applicant's application is without merit and is hereby dismissed. It is so ordered.
p. 4Final orders - dismissal of the resentencing application

Issues in the judgment

#
minor

The judgment inconsistently spells the cited authority's name, 'Ali Abdullah Mwanza' in the grounds and 'Ali Abdallah Mwanza' in the applicant's affidavit recital.
