The bottom line

#

Kenya's Court of Appeal upheld a death sentence for the murder of a toddler, confirming the death penalty remains a lawful option after the Muruatetu decision.

What this practically means

#

Executive summary

#
This was a first appeal to the Court of Appeal at Nyeri against the death sentence imposed on Vincent Gikundi Nyaga following his conviction for the murder of his 2½-year-old son by the High Court at Meru. The appellant murdered the child on 15th February 2009 after luring the child's mother to surrender the boy, strangling him and inflicting multiple skull and cervical fractures, and dumping the body in a pit latrine. He was convicted after trial before Wendo, J and sentenced to death by Mabeya, J on 21st March 2018. Before the Court of Appeal, counsel abandoned the appeal against conviction and pursued only the sentence, invoking the Supreme Court's decision in Francis Karioko Muruatetu, submitting that the appellant had spent 15 years in custody, was remorseful, reformed, and now 62 years old, and asking for resentencing to a term of imprisonment. The court held that Muruatetu declared only the mandatory nature of section 204 of the Penal Code unconstitutional; the death sentence remains lawful and a trial judge retains discretion to impose it after considering aggravating factors, mitigation, personal circumstances and victim impact. The court found that Mabeya, J had been aware of Muruatetu and had properly exercised that discretion on the circumstances of the offence. Adopting the settled principles in Bernard Kimani Gacheru v Republic on non-interference with discretionary sentences, the court agreed the death sentence was well deserved and dismissed the appeal.

Questions the Court framed

#

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

  1. 1.Whether the death sentence imposed on the appellant should be reviewed to a term of imprisonment in light of Francis Karioko Muruatetu & Another v Republic
  2. 2.Whether the trial judge properly exercised the discretion now available after Muruatetu in imposing the death sentence

Key legal issues

#
01

Whether the mandatory-death declaration in Muruatetu entitled this appellant to resentencing

Holding

No. Muruatetu removed only the mandatory nature of the death sentence; the death sentence remains lawful and the trial judge, having considered the circumstances and mitigation, properly exercised discretion in imposing death.

Reasoning

The court noted that Mabeya, J was aware of Muruatetu at sentencing and considered the circumstances of the murder before imposing death. The Supreme Court had declared only the mandatory wording of section 204 unconstitutional, leaving the death penalty available. The discretion conferred by Muruatetu had in fact been exercised, and the aggravating circumstances - the savage killing of a 2½-year-old child - amply justified the sentence.

02

The standard for appellate interference with a discretionary sentence

Holding

An appellate court will not interfere with sentence unless it is manifestly excessive, or the trial court overlooked a material factor, took into account wrong material, or acted on a wrong principle.

Reasoning

The court adopted the classic statement in Bernard Kimani Gacheru v Republic, reaffirming that sentence rests in the discretion of the trial court and depends on the facts of each case. The fact that the appellate court might itself have imposed a different sentence is not sufficient ground for interference. None of the recognised grounds for interference was shown here.

Legal principles established

#
  • The death sentence remains a lawful sentence in Kenya; only the mandatory nature of section 204 of the Penal Code was declared unconstitutional, leaving trial judges discretion to impose either death or a term sentence.
  • An appellate court will not interfere with a trial court's discretionary sentence unless it is manifestly excessive, or the trial court overlooked a material factor, took into account wrong material, or acted on a wrong principle.
  • In exercising sentencing discretion after Muruatetu, a trial judge may impose the death sentence where aggravating factors, mitigation, personal circumstances of the convict and victim impact statements justify it.

Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.

The appeal is devoid of merit and is accordingly dismissed.
p. 3Final orders - dismissal of appeal against sentence
We agree with Mabeya, J that the death sentence was well deserved.
p. 3Upholding of death sentence
a trial Judge has discretion to impose a death sentence taking into account aggravating factors, mitigation, personal circumstances of the convict and victim impact statement or any other extenuating circumstances.
p. 3Sentencing discretion after Muruatetu
On appeal, the appellate court will not easily interfere with sentence unless, that sentence is manifestly excessive in the circumstances of the case, or that the trial court overlooked some material factor, or took into account, some wrong material, or acted on a wrong principle.
p. 3Standard for appellate interference with sentence

Issues in the judgment

#
minor

The judgment cites the Muruatetu decision as '(2016)' and '[2016] eKLR', but the sentencing and mitigation discussion occurred in 2018, and the well-known Muruatetu decision was delivered in 2017 - the year in the citation may be inaccurate; noted as printed in the judgment.
